Rotation

The Rotation tool rotates an object by a specified angular value with respect to a point.
Note: The angular value may be any measurement or numerical value, regardless of units. The
units are presumed to be degrees by the software. A positive angular value rotation is performed in
a counter-clockwise direction.
To create specific angles of rotation, please refer to " Numerical Edit" in the chapter "Using the
Display Toolbox."
Rotating an object
1.
Select Rotation from the Transform toolbox.
2.
Select the object to rotate.
3.
Select the point of rotation.
4.
Select the angular value of rotation.
Modifying a rotation
Change the rotated image by either modifying the figure
that defines the angle of rotation, editing the value
created by Numerical Edit , moving the rotation point, or
changing the original object. Because it is a dependent
object, you cannot change the rotated image directly.
