Rotating Entities

Commands: ROTATE and ROTATE3D

You can rotate entities about a specified point at a specified rotation angle or by an angle referenced to a base angle. The default method rotates the entities using a relative rotation angle from their current orientation.

By default, angles start at 3 o'clock and increase in a counter-clockwise direction. If you want to rotate in a clockwise direction you can enter a negative angle by using a minus sign.

 

NOTES

  • The Angular Base is controlled by the ANGBASE system variable, which in turn refers to the current UCS.

  • The Angle Direction is controlled by the ANGDIR system variable, which sets the positive angle direction from angle 0 with respect to the current UCS.

 

The Copy option of the Grips Editing commands allows to create multiple copies of the entities being stretched, moved, rotated, mirrored or scaled.

Rotating a selection set

  1. Do one of the following:

  2. Click the Rotate tool button () on the Modify toolbar.

  3. Choose Rotate in the Modify menu.

  4. Type rotate or RO in the command bar.

The command bar reads: Select entities to rotate:

  1. Select the entities, then right click or press Enter.
    The command bar reads: Rotation point:

  2. Specify the rotation point.
    The command bar reads: Copy/Base angle/<Rotation angle>:
    A prompt menu displays:

  3. (option) Choose Copy in the prompt menu or type C, then press Enter to create a rotated copy of the selection set.

  4. Specify the rotation angle.
    The selection set is rotated.

 

NOTE

Use the Center option of the Array command if you want to keep the original entities.

Rotating a selection set in reference to a base angle

  1. Do one of the following:

  2. Click the Rotate tool button () on the Modify toolbar.

  3. Choose Rotate in the Modify menu.

  4. Type rotate or RO in the command bar.

The command bar reads: Select entities to rotate:

  1. Select the entities, then right click or press Enter.
    The command bar reads: Rotation point:

  2. Specify the rotation point.
    The command bar reads: Copy/Base angle/<Rotation angle>:
    A prompt menu displays:

  3. (option) Choose Copy in the prompt menu or type C, then press Enter to create a rotated copy of the selection set.

  4. Do one of the following:

  5. Choose Base angle in the prompt menu.

  6. Type B in the command bar, then press Enter.

The command bar reads: Base angle <0>:

  1. To specify the base angle do one of the following:

  2. Type the base angle in the command bar.

  3. Click the rotation point again, then click a second point.

The command bar reads: New Angle.

  1. Do one of the following:

  2. Type the new angle in the command bar.

  3. Click a point to define the new angle.

Rotating in 3D

  1. Do one of the following.

The command bar reads: Select entities to rotate:

  1. Select the entities, then right click or press Enter.
    The command bar reads: Select axis by: Entity/Last/View/Xaxis/Yaxis/Z-axis/<2 points>:

  2. Press Enter to define the rotation axis by specifying two points.

  3. Specify the first rotation axis point.

  4. Specify the second rotation axis point.
    The command bar reads: Reference/<Rotation Angle>:

  5. Specify the rotation angle.
    The selection set is rotated clockwise, looking in the rotation axis direction.
