Rotating the drawings

CADD drawing allows you to rotate selected drawing objects to a specified angle. To rotate, you need to select
the drawing objects, enter a reference point (or base point) and the rotation angle. The base point acts as a
pivot point around which the objects are rotated. The rotation angle determines by how much the objects will be
rotated and in which direction.
Reference angle rotation
A positive angle causes counterclockwise rotation, and a negative angle produces clockwise rotation. If you
respond to the last prompt with r, you can specify the current rotation and the new rotation you want. AutoCAD
