Rotate an object based on an existing angle

You can rotate an object based on a known angle or the angle of two points you select. In the following example, you want to rotate the chair and desk on the right to match the chair and table on the left. The new angle is unknown.

1. At the Command prompt, enter rotate.
2. At the Command prompt to Select objects: Select the objects to rotate.
3. At the Command prompt to Specify base point: In the object to rotate, select the appropriate base point.
   (In the following example, the base point is the midpoint of the back of the chair. All selected objects rotate around that base point.)

 

4. At the Command prompt to Specify rotation angle or [Copy/Reference] <0>: R

Note: The reference option refers to the current angle of the object to rotate. If you know the angle, known, enter that value. For unknown angles, enter R (as shown previously) to select a reference angle.

5. At the Command prompt to Specify the reference angle <0>: Enter a known angle, or select a first and second point to specify the existing angle.

6. At the Command prompt to Specify the new angle or [Points] <0>: P
7. Select the starting point of the new angle, and then select the endpoint. The first object is rotated to match the angle of the second object.
