Rotate Objects
You can rotate objects around a specified point. To determine the angle of
rotation, you enter an angle value or specify a second point.
Entering a positive angle value rotates the objects counterclockwise or clock-
wise, depending on the Direction Control setting in the Drawing Units
dialog box. The plane of rotation and the direction of the zero angle depend
on the orientation of the user coordinate system.
Rotate an Object by a Specified Angle
You rotate objects by choosing a base point and a relative or absolute rotation
angle. Specify a relative angle to rotate the object from its current orientation
around the base point by that angle. Specify an absolute angle to rotate the
object from the current angle to a new absolute angle.
You can rotate an object by specifying a relative angle using one of two
methods:
■ Enter a rotation angle value from 0 to 360 degrees. You can also enter
values in radians, grads, or surveyor bearings.
■ Drag the object around the base point and specify a second point. Turning
on Ortho and Polar Tracking, or using object snaps for the second point,
is often useful with this method.
In this example, you rotate the plan view of a house by selecting the object
(1), specifying a base point (2), and specifying an angle of rotation by drag-
ging to another point (3).
Rotate an Object to an Absolute Angle
Sometimes it is easier to rotate to an absolute angle with a reference option.
