How to rotate an object along a line in AutoCAD. Use the Rotate tool to rotate objects. How to turn in AutoCAD at a certain angle
You can rotate an object (geometric element, text, image, block) in AutoCAD in two ways, using the appropriate command or the so-called "Handles".
Rotate objects using the command TURN (_ROTATE) is performed as follows:
1. Run the command by clicking the corresponding button on the editing toolbar, enter in command line TURN (_ROTATE) or choose from top menu Edit -\u003e Rotate.
2. Select the object or objects to rotate. This command also supports preselection if objects were selected before running the command TURN, this item can be skipped.
4. Enter the value of the angle of rotation in the command line and press Enter, or indicate with the cursor on the screen, completing the rotation by clicking the left mouse button. The command has options "Copy" and " Reference angle". If you select" Copy "the base element will remain, its copy will be rotated. The" Reference Angle "option allows you to alternatively specify the amount of rotation on the screen by choosing a start and end direction.
Rotating objects with grips
1. Select the objects object or objects to be rotated.
2. Click on the marker (handle). This marker will be the center of rotation of objects.
3. By right-clicking, select the "Rotate" option.
4. Similarly to the previous method, enter the value of the angle of rotation, or select by clicking the right button.
In AutoCAD, clockwise rotation is taken as a positive angle, and a negative one is counterclockwise.
Important. These methods allow objects to be rotated around a single center. In the event that you need to rotate a lot of objects around their own centers, so that they remain in their places, it is disassembled in detail
New to Autodesk AutoCAD? Have you already started work, but are facing difficulties? Do not know, how to rotate an object in AutoCAD? So this article is for you. Here we will explain everything in detail and with screenshots.
So let's say you have AutoCAD open. Let's draw a simple object, for example "Sad smiley".
Now let's say we want to cheer him up a bit and change his mouth expression. It was done using the Arc tool. 3 points ". This is where the arc is drawn from three points.
In order to change the facial expression, we need to rotate this arc 180 degrees.
To the question “ How to turn in AutoCADthis very arc? " I answer: "As indicated in my instructions."
1) Select the "Rotate" button on the editing panel.
2) We need to select the object we need (in this case, the arc). When you hover over the selected object, it becomes a bold line.
3) Click, and the object becomes a thin dashed line.
4) If you are sure of the object that you have selected, then click on the right mouse button. This will confirm the selection.
5) Now we need to find the point from which the turn will be made. To do this, point to the beginning (1) and the center of the arc (2). Thus, we will find the center point for the rotation (3). Click on it (point 3).
6) Now try moving the cursor around point 3.
7) You can see that we can twist our arc as we like. But we need to rotate it exactly by 180 degrees, so in the "Angle of rotation or" field, write "180". Press "Enter".
8) See what we did? This is "Funny Smile". Congratulations. You have successfully changed the facial expression of our test subject "Smile".
Let's not dwell on this and continue the lesson. Now let's answer the question “ How to rotate a drawing in AutoCAD?».
9) Just as described earlier, select the "Rotate" button on the toolbar.
10) Select our entire object ("Cheerful smile"). To do this, move the cursor to the left top corner drawing, press the left key once, lower the cursor to the lower right corner so that all the objects we need to rotate (in this case, the entire face) fall into the resulting blue area.
11) Press the left mouse button once. Everything previously selected has become thin dashed lines.
12) Press the right mouse button to confirm the selection. Now we indicate the pivot point. Select the very center of the face. Hover the cursor over points 4 and 5. Click on point 6.
13) Roll the mouse cursor around the selected point 6. If you turn the cursor and wait a little, you will see a phantom, which is shown by the main line. It will show you the possible location of the object during the turn.
14) We enter 45 in the "Angle of rotation or". Thus, we have rotated the object by 45 degrees.
Congratulations. You have learned how to rotate single objects or multiple objects in AutoCAD.
Now, finally, I will show you how to rotate text in autocad... We continue our training.
15) Click on the "Multi-line text" button
16) Similar to step 10 of our tutorial, select the place where you want to place the text.
17) Click in the lower right corner and get:
18) Enter the text. For example, "Smile".
19) It turns out that:
20) If you wish, you can independently edit the height of the text.
21) Let's rotate the text. We follow steps: 1, 2, 3 and 4. Then follow steps: 12, 13, 14.
Congratulations, you've learned how to rotate text in AutoCAD.
In this case, we need to unfold the rectangular object that represents the contour of the facade of the small pedestal in the drawing, 90 ° counterclockwise. To do this, we need to use the Rotate tool, which is new for you.
Council. In AutoCAD, counterclockwise rotation is considered positive and clockwise rotation is negative. If you are not satisfied with the default angle direction, you can change it using the dialog box Choice of directionthat opens after clicking the button Direction dialog box Drawing units (see figure 3.3).
1. Run the tool Turnby clicking the button Turn toolbars Edit or by choosing the command from the menu Change »Rotate or by entering the command in the command window Turn or simply pov... AutoCAD prompts you to select the objects to rotate. Click on one of the lines of the elevation of the small cabinet and press Enter to complete the selection.
Note. By clicking on one of the lines of the rectangle, you will immediately understand how it differs from the rectangles created from separate lines - in this case, all four lines of the object will be selected at once, regardless of which line you click on. Rectangles created with the command Rectangle, consist of four segments of the so-called polyline, which unites all segments into one object. For more information on polylines, see Chapter 10, About Labeling a Drawing.
2. AutoCAD in the command window prompts you to select the base point around which you want to rotate. Click on the button End toolbars Object Snap.
3. Move the pointer to the upper left corner of the facade outline (the point at which it touches the outline of the small cabinet). Once AutoCAD recognizes this point as the end point, left-click to grab its coordinates as the base pivot point. Before proceeding to the next step, make sure that the indicator button is ORTHO in the status bar is off (if it is not, click it to turn off orthogonal drawing mode). This mode, which provides drawing only horizontally and vertically, is convenient in many cases, but in this situation it will only hinder us. For more information on orthogonal mode, see Chapter 5.
4. Move the pointer from the base point - moving the pointer will rotate the facade outline (Fig. 4.46). The command line will prompt Rotation Angle or [Copy / Reference Angle]:that prompts you to set the rotation angle.
Figure: 4.46 The second rectangle rotates around the base point
5. Enter 90. The rectangle will be rotated 90 °, as a result of which our "door" of the small cabinet will move to the "closed" position, as in fig. 4.3, and command execution Turn will automatically end.
Now we will digress from the task of creating rectangles for a while and get acquainted with another new tool for creating arcs.
You met the COPY command in Chapter 3 (see also the video "Lesson 3.3. Copying, pasting and deleting objects"). Let's repeat the main points related to copying objects in AutoCAD with specifying a base point.
1. Create a simple object or open a drawing containing such an object.
2. Call the COPY command by entering it at the command line or by pressing the Copy (Copy) tab Home (Main) in the group Modify (Editing) tape. Alternatively, click Copy (Copy) on the toolbar Modify (Edit) or use the menu command Modify\u003e Copy (Edit\u003e Copy). A prompt will appear:
Select objects:
Select an object. A prompt will appear:
Select objects:
Press the key Enter or Space. AutoCAD asks for a base point:
Specify base point or
3. Click on the drawing area to select the base point and move the mouse to indicate the translation vector of the object copy. In this case, the program will ask you to specify the second point:
Specify second point or
4. Click to paste the copy. AutoCAD will prompt you:
Specify second point or
Continue pasting points, making multiple copies, as shown in Fig. 3.15.
5. Press the key to end the command. Enter, select the Exit option or enter the letter E at the command line.
Mirroring objects
The MIRROR command creates a mirror (symmetrical) reflection of objects about an axis of symmetry defined by the two selected endpoints.
After running the MIRROR command, AutoCAD will display the prompt:
Select objects:
Select the objects you want to mirror and press the key Enter, to accept the selection set. Then AutoCAD will ask you to define the two extreme points of the line, relative to which the selected objects should be reflected, as shown in Fig. 6.1.
Figure: 6.1. Selecting a Centerline for Mirroring Objects
After selecting the second point, the program will ask you if you want to delete the originally selected objects:
You have a choice: keep the original objects in the drawing along with their copies, or keep only the reflected objects and delete the original ones. By default, it is suggested not to erase the original objects, so when choosing this option, just press the key Enter. To erase the originals of the objects, you can select the Yes option or enter the Y command followed by pressing the Enter. In any case, whichever you choose, the command ends up flipping the object.
Usually, when you mirror an object with text, you want the text to retain its original orientation - from left to right (Figure 6.2).
Figure: 6.2. Maintain text orientation when mirroring an object
The AutoCAD MIRRTEXT system variable controls the orientation of text when mirrored. Setting this variable to 1 will cause the entire text to be reversed, as shown in Fig. 6.3. If the MIRRTEXT variable is set to 0, then the text will retain its original orientation.
Figure: 6.3. Reversing text when mirroring
By default, the MIRRTEXT system variable is set to 0.
Advice
To change this value, enter MIRRTEXT at the command line. At the prompt Enter new value for MIRRTEXT<0>: Enter the required value (0 or 1).
Let's consider the order of performing mirroring of objects.
1. Open an existing drawing or create a new one containing a simple object.
2. Call the MIRROR command by clicking the corresponding button on the tab Home (Main) in the group Modify Modify Modify\u003e Mirror (Edit\u003e Display). Another way is to enter the MIRROR command on the command line.
3. Select the object to be flipped. The program will ask you to specify the first point of the mirror axis:
Specify first point of mirror line:
Specify second point of mirror line:
5. Turn on Ortho Mode (Orthogonal mode) by clicking the corresponding button at the bottom of the program window (if it is not currently pressed).
6. Select the second point below the first using the help mode Ortho Mode(Orthogonal mode) (Fig. 6.4). The program will display the object and issue a request:
Erase source objects?
Figure: 6.4. Mirroring an Object
7. Press the key Enter, to accept the default and keep the original object.
Creating arrays
Array call a set of homogeneous objects that form a single whole. Arrays of an AutoCAD program are a collection of copies of one object, located at an equal distance from each other. Since arrays are associated with coordinate offsets, they can be rectangular and polar. In rectangular arrays, objects are displaced along the coordinate axes, and such arrays are rectangular structures. In polar arrays, copying occurs around one point, as a result of which such aggregates are circular.
The ARRAY command is used to create an array. It can be called by clicking the button of the same name on the tab Home (Main) in the group Modify (Editing) the ribbon or toolbar Modify (Editing). You can also use the menu command Modify\u003e Array (Edit\u003e Array) or type ARRAY at the command line.
After running the command, a dialog box will appear Array (Array) (Figure 6.5).
Figure: 6.5. Array Dialog Box
At the top of the window there is a switch that allows you to select the type of array: rectangular or polar. To the right of it is the button Select objects (Select Objects) by clicking which you can select objects to copy. The content of the central part of the window changes depending on the selected type of array. Various copy options can be specified here. On the right is the preview area.
Rectangular array
To create a rectangular array, set the radio button in the window Array(Array) to position Rectangular Array (Rectangular array). This will make the following options available.
Use fields to change the number of rows and columns Rows (Strings) and Columns (Columns). As you change the number of rows and columns, the preview image will update.
Fields Row offset (Offset between lines) and Column offset (Offset between columns) are used to change the distance between rows and columns. With a positive value of the parameter Row offset (Offset between lines) lines are created in the positive direction of the axis Y (up), with negative - in the opposite direction. Negative value in the field Column offset (Column Offset) means the columns will be created on the left. Pay attention to the values \u200b\u200bof these parameters and the image in the preview area in Fig. 6.6.
Figure: 6.6. Specifying column and row offset
You can define the offset of rows and columns independently by entering values \u200b\u200binto the text boxes. In addition, to the right of the margins is a combined button that allows you to select row and column offset by defining two opposite corners of the rectangle. Length (x) rectangle - column offset, width (y) - line offset.
To indicate the general corner of the array, use the field Angle of array (Corner of the array). You can specify the numerical value of the angle in this field or by clicking the button Pick Angle of Array (Pick a corner of the pattern), located to the right of the field, select two points in the drawing. AutoCAD will measure the slope of the line between these two points and use it as the slope of the array (Figure 6.7). The default angle is 0 °.
Figure: 6.7. Setting the common corner of a rectangular pattern
When you change each of these values, the preview image is updated to show you what the resulting array will look like. Abstract blocks are used here to represent actual objects. To see how your array will look in the drawing, click on the button Preview (Preview). AutoCAD will temporarily hide the dialog Array (Array) and will show the array using the objects you selected. Button Preview (Preview) will only be available after you select objects.
Reinforce your rectangular array skills with the following steps.
1. Draw an object such as an ellipse.
Array(Array).
Rectangular Array (Rectangular array) and click on the button Select objects (Object selection). Select the ellipse and press the key Enter to return to the window Array (Array).
4. Enter the following parameter values: Rows (Lines) - 4, Columns(Columns) - 6, Row offset (Offset between lines) - 2 4 0, Column offset (Offset between columns) - 2 8 0, Angle of array (Angle of the array) - 10.
5. Click the button Preview (Preview). A preview of the array appears on the screen. If the window Array (Array) prevents you from seeing the array, just drag this window by the title bar.
6. Click the button Accept (Accept) to complete the ARRAY command. The drawing should resemble that shown in fig. 6.8.
Figure: 6.8. Rectangular array of ellipses at an angle of 10 °
Polar array
To create a polar array, select the radio button in the window Array (Array) to position Polar Array (Polar array) (Figure 6.9).
Figure: 6.9. Polar array creation window
The following options become available.
Fields X and Y serve to indicate the center of the circle along which the array elements will be located. The center can also be set by clicking the button Pick center point (Pick the center point) located to the right of the margins and point it in the drawing with the mouse.
A polar array is characterized by three parameters: the number of elements created (Total number of items), a common corner filled with an array (Angle to fill), and the angle between the elements (Angle between items).To create an array, you need to set two parameters, for which in the drop-down list Method (Method) should choose which parameters will be used.
Note
When specifying a fill angle or an angle between elements, a positive value will copy the elements in a counterclockwise direction, and a negative value will copy the elements in a clockwise direction.
At the bottom of the window is a checkbox that lets you specify whether to rotate individual objects in the array. When the checkbox is unchecked, objects retain their original angle, and when checked, each element rotates around its base point when it is built around a circle.
When the button is pressed More (More) will be displayed additional settings rotation of objects (fig. 6.10). By default, objects rotate in their characteristic way. Linear objects (lines, polylines, rays, etc.) - relative to their starting point. Circles, arcs, and ellipses are relative to their center points. Blocks and text rotate around their insertion point, and lines rotate around the middle. In order for them to rotate about the base point, you must uncheck the box Set to object "s default (Default settings) and in the fields X and Y specify the coordinates of the point.
Figure: 6.10. Object rotation options
Consider the process of creating a polar array.
1. Draw a shape like the one shown in fig. 6.11.
Figure: 6.11. Original shape for polar array
2. Issue the ARRAY command. A dialog box appears on the screen. Array (Array).
3. Set the switch to position Polar Array (Polar array) and click the button Select objects (Object selection). Select the source shape and press Enter to return to the window Array (Array).
4. Click the button Pick center point(Pick Center Point) and set the center of the pattern to a point below the shape on its centerline.
5. In the drop-down list Method (Method) select item Total number of items & Angle to fill (Total number of elements and fill angle).
6. Set the parameter Total number of items (Total number of elements) is 8, and the parameter Angle to fill (Filling angle) - 3 6 0.
7. Press the button OK. Your drawing should resemble the one shown in fig. 6.12.
Figure: 6.12. Polar array
Rotating objects
To rotate objects, use the ROTATE command. It can be used to rotate objects at a certain angle and around a specified point.
To run the ROTATE command, press the button Rotate (Rotate) tab Home (Main) in the group Modify (Editing) the ribbon or toolbar Modify (Editing). You can also execute the menu command Modify\u003e Rotate (Edit\u003e Rotate) or enter ROTATE at the command line.
After running the command, a prompt will appear:
Select objects:
Select the objects you want to rotate and press the key Enteror Space to accept the selection set. The program will issue the following request:
Specify base point:
In response, use the mouse to set the point around which the rotation will occur, after which the last request will appear - about specifying the rotation angle:
<0>:
The angle of rotation can be specified in one of three ways:
With the mouse, using the base point as the corner vertex;
By entering the angle value from the keyboard;
Using the Reference parameter, set a start angle and then a new one.
Note
It is also possible to specify the base point using Cartesian coordinates in the field near the pointer or on the command line. For example, to rotate an object using the drawing origin as the base point, you can enter 0.0 and press Enter at the Specify base point: prompt.
To set the angle of rotation with the mouse, simply move the pointer around the base point until the object takes the required position (Fig. 6.13).
Figure: 6.13. Object preview after rotation
Advice
You can use Ortho Mode or polar tracking aids to quickly and accurately rotate objects to the desired angles.
The rotation angle value can simply be entered from the keyboard. Angles are measured using the current base angle and direction. The default base angle is 0 ° (east) with counterclockwise measurement direction. At the time of command execution, the current direction and base angle are displayed on the command line as follows:
Current positive angle in UCS: ANGDIR \u003d counterclockwise ANG– BASE \u003d 0
Entering an angle value and pressing a key Enter rotate the selected object by the specified angle.
Note
You can enter a negative angle and rotate objects in the opposite direction. For example, entering a value of -45 ° is equivalent to entering a value of 315 °: the object will take the same position as a result of rotation in different directions.
The Reference parameter lets you rotate objects by specifying a direction or starting angle and then specifying a new, absolute rotation angle. AutoCAD will rotate the object by calculating the difference between the direction angle and the new angle.
This parameter is invaluable if you don't know the existing rotation angle of the object. Using the grip function, you can lock two points on objects that define the current angle. Then, in response to the request:
Specify the new angle or<0>:
it is necessary to enter the angle from the keyboard or, using the Points parameter, select two points to define a new angle (Fig. 6.14).
Figure: 6.14. Rotation using the Reference parameter
With the Copy parameter of the ROTATE command, you can not only rotate objects, but also create copies of them. When this option is selected in response to the Specify rotation angle or<0>: the following prompt appears:
Rotating a copy of the selected objects.
Specify rotation angle or<0>:
The angle of rotation can be set using any of the methods described earlier. In fig. 6.15 shows the effect of using the Copy parameter when executing the ROTATE command.
Figure: 6.15. The result of rotating objects with copying
To practice the acquired knowledge, follow these steps.
1. Call the ROTATE command and select the object in the drawing to be rotated. The first prompt appears:
Specify base point:
2. Specify the center of rotation, and the program will ask you to determine the angle of rotation:
Specify rotation angle or<0>:
3. Use the mouse to rotate the object to any angle.
4. To return the object to its original position, press the Esc. Alternatively, click Undo (Cancel) on the panel quick access or on the toolbar Standard (Standard).
5. Call the ROTATE command again and select the object in the drawing to rotate. A prompt will appear:
Specify base point:
6. Pick the center of rotation. You will be prompted to determine the angle of rotation:
Specify rotation angle or<0>:
7. Enter the value 4 5 and press the key. Enter. The object will be rotated 45 °.
8. Enter the U command and press the key Enter or Space, to undo the changes.
9. Call the ROTATE command again and select the object in the drawing. After that, the program will ask you to specify the base point:
Specify base point:
10. Pick the center of rotation. A prompt will appear:
Specify rotation angle or<0>:
11. Select the Copy option using the cursor keys or by typing C at the command line and pressing Enter.
12. Enter the value 6 0 and press the key. Enter. The object will be rotated and copied.
Scaling objects
To resize objects in AutoCAD use the SCALE command (see also the video "Lesson 6.1. Rotating and scaling objects").
To run the SCALE command, press the button Scale (Zoom) tab Home (Main) in the group Modify (Editing) the ribbon or toolbar Modify (Editing). You can also execute the menu command Modify\u003e Scale (Edit\u003e Scale) or enter SCALE on the command line.
After calling the SCALE command, the program will ask you to select objects:
Select objects:
Select the objects to be scaled and press Enter or Space, to accept the selection set. The following query requires you to specify a base point from which the zoom will occur:
<1.0000>:
The scaling factor can be specified in one of three ways:
With the mouse, using the base point as the vertex;
By entering the coefficient from the keyboard;
Using the Reference parameter, set the initial size (length) and then the new one. This can be done both from the keyboard and by pointing points on the drawing.
When using the mouse, you simply move the pointer by selecting a point in the drawing to indicate the desired scale factor. This displays a preview of the object (Fig. 6.16).
Figure: 6.16. Changing the scale of an object
Note
It is also possible to enter the Cartesian coordinates of the base point in the field near the pointer or on the command line. For example, to scale an object using the drawing origin as the base point, you can enter a value of 0.0 and press Enter at the Specify base point: prompt.
The scale value can also be entered using the keyboard. At a scale factor greater than 1, objects are enlarged, and at a smaller scale, their size is reduced. The scaling factor must always be greater than zero.
The Reference parameter allows you to scale objects by specifying an initial length and then a new, absolute one. AutoCAD determines the required scale factor by calculating the difference between the start and new length. You can enter the length using the keyboard or select two points in the figure that define the relative length. The Reference parameter is simply necessary if you do not know the length of an existing object, but have only the required one. Using the gripping function, you can lock two points on an object that define its length. Then AutoCAD will offer to set a new length:
Specify new length or<1.0000>:
You can enter the length using the keyboard, or use the Points parameter to select two points to specify a new length.
Using the Copy parameter of the SCALE command, you can not only change the scale of objects, but also create copies of them. When this parameter is selected in response to the Specify scale factor or<1.0000>: the following prompt appears:
Scaling a copy of the selected objects.
Specify scale factor or<1.0000>:
You can use any method to determine the scale factor. An example of resizing with copying an object is shown in Fig. 6.17.
Figure: 6.17. Result of rescaling with copying the object
Reinforce what you learned by doing the following exercise.
1. Call the SCALE command and select an object. The screen will ask you to determine the base point:
Specify base point:
2. Draw a base point. The program will ask you to determine the scale factor:
Specify scale factor or<1.0000>:
3. Scale the object in any aspect using the point selected by the mouse pointer.
4. Enter the letter U in the command line or press the Undo (Undo) on the Quick Access Toolbar to return the object to its original size.
5. Reissue the SCALE command and select the object. The screen will ask you:
Specify base point:
6. Designate a base point, and then a request for determining the scale factor will appear:
Specify scale factor or<1.0000>:
7. Enter the value 2 and press the key. Enter or Space. The object will be enlarged twice.
Breaking an object
The BREAK command allows you to remove parts of an object or split it in two. To start it, press the button Break (Break) tab Home (Main) in the group Modify (Editing) the ribbon or toolbar Modify (Editing). You can also execute the menu command Modify\u003e Break(Edit\u003e Break) or enter BREAK at the command line.
After calling the BREAK command, the program will prompt you to select an object. As you select the object, you specify the first breakpoint. If you want to change it, you must select the First point option when prompted by the Specify second break point or: command to re-specify the first point. Then, after specifying the first point, when prompted by the program, specify the second point, and the gap will be created.
If you need to split one object into two without breaking its geometry, just use the @ symbol to define the second point. In this case, the program will place the second point in the same coordinates as the first one. As a result, two objects will be created, together making up the original.
Sometimes the type of new objects created by splitting may differ from the original. When you break a line, AutoCAD simply creates two lines, however, when you break a circle, the program converts it to an arc. The order in which the points are selected determines how much of the circle is saved. AutoCAD will remove the first part in a counterclockwise direction.
When choosing the second break point, there are a few things to keep in mind. First, if you select a second point somewhere outside the object, AutoCAD will project the breakpoint along a line perpendicular to the object and passing through the selected point. Second, if the second breakpoint lies outside the object's boundaries, AutoCAD will simply delete everything between the first point and the object's boundary.
Follow these steps to create an object break.
1. Call the BREAK command and select a point on an object (for example, a circle) that will serve as the first break point. AutoCAD will ask you to pick the second point:
Specify second break point or:
2. Pick a second point somewhere near the circle to break the circle and get an arc part of it. The result should look something like the one shown in Fig. 6.18.
Figure: 6.18. The result of breaking a circle
Create a chamfer
Drawing objects can be connected by creating chamfers (beveled lines). To "chamfer" in the language of metalworking means to bevel a rectangular face of a part. The presence of such a function in AutoCAD is due to the fact that in many cases it is inconvenient to create the image of these parts of the drawing using basic editing tools.
Use the CHAMFER command to create a chamfer (beveled corner) between two intersecting objects. It can be called up by clicking on the button Chamfer (Chamfer) on a tab Home (Main) in the group Modify (Editing) the ribbon or toolbar Modify (Editing). You can also execute the menu command Modify\u003e Chamfer (Edit\u003e Chamfer).
When using the CHAMFER command, you must specify two distances (from the intersection point to each object) or a distance and angle for the chamfer. The mEthod parameter lets you choose which way to create chamfers to use.
Distance method
Through this method you define the distance from the intersection to the object along each line. The program calculates the distances from the intersection point to the first and second objects and then draws a line between these two points.
The Distance parameter allows you to set the chamfer lengths. The first length is used for the first selected object, the second for the second.
If the chamfer lengths are equal, a 45 ° chamfer is drawn. When you set the first distance, AutoCAD assigns that default value to the second distance. To accept this, just press the key Enter in response to the program's request to enter the second chamfer distance.
Angle setting method
The angle method uses distance and angle to define the chamfer line. The distance is subtracted from the first selected object to define the starting point, and the chamfer line is drawn at a specific angle until it intersects with the second object. By default, the angle is measured counterclockwise from the first object.
When you chamfer a polyline using the Polyline parameter, the first and second objects are defined in the order in which the polyline was drawn. If you are in doubt or are not getting the expected results, the best waymay not use the Polyline parameter, but simply chamfer the polyline sections separately.
Let's look at how to create a chamfer.
1. Draw two lines perpendicular to each other (fig. 6.19).
Figure: 6.19. Original lines for chamfering
2. Run the CHAMFER command and select the Angle parameter. The screen will ask you to define the chamfer length on the first line:
Specify chamfer length on the first line<0.0000>:
3. Enter the value 90 and press the key. Enter or Space, to set the length. You are prompted to specify the angle of the chamfer:
Specify chamfer angle from the first line<0>:
4. Enter the value 65 and press the key. Enter or Space to set the chamfer angle. The program will ask you to select the first line:
5. Then enter the second line in response to the request:
AutoCAD will skew the corner. Note that 90 is measured from the first line you selected. The result should look something like the one shown in Fig. 6.20.
Figure: 6.20. Chamfering by Entering a Single Distance and Angle
6. Enter the U command to undo the last chamfer.
7. Run the CHAMFER command again and select the Distance parameter. Set the first distance to 110.
8. AutoCAD sets the second distance to the default value corresponding to the first distance. Press the key Enter, to accept this meaning. AutoCAD will ask you to select the first line:
Select first line or:
Select one of the lines as the first.
9. In response to the following request, provide the second line:
Select second line or shift-select to apply corner:
10. AutoCAD will chamfer and the drawing will look like the one shown in fig. 6.21.

You got acquainted with the basics of editing objects in AutoCAD, mastered such basic techniques as copying, mirroring, rotating, resizing objects, as well as more specific tools - creating an array of objects, ripping and chamfering.
Knowledge and confident possession of editing techniques allows you to optimize the process of creating drawings, diagrams, plans, etc. You will be able to select the supporting structural elements of objects, find symmetry and similarity. This is how AutoCAD gives you more possibilities for creativity, taking over most of the chores.
To rotate any object (graphic element, text, table, etc.) in AutoCAD, just use the "Rotate" editing command.
Rotation in AutoCAD is performed according to the specified algorithm (in order not to remember it, just carefully monitor the information on the command line):
1. Select the Rotate command.
2. Pick the object to be rotated.
3. Specify the base point (ie the point around which the rotation will be performed). Depending on the change in the location of the base point, the final result will change with the same actions and parameters.
4. Specify the rotation angle OR select one of the suboptions (copy or reference angle).
As you can see, the question "how to rotate an object in AutoCAD" is quite simple. However, let's take a closer look at the nuances that arise when we want to set the AutoCAD rotation angle.
How to turn in AutoCAD at a certain angle
It was discussed above that during the execution of the "Rotate" command, you need to set the angle. This can be done graphically, i.e. using anchors and tracking lines directly in the work area. You can also enter the exact value using the keyboard.
If initially the turn was specified incorrectly, then you can refer to the AutoCAD suboption "Reference angle" (you do not need to cancel the turn!). This will allow you to specify a new angle relative to the existing one. Angle range 0-360 0.
There is very quick way perform rotation in AutoCAD using the "handles" of the object.This method is discussed in detail in the article "How to transfer a drawing in AutoCAD". The same material is clearly demonstrated in the video course “
