Using this option, you can rotate the section contour or certain parts of it about a selected point. Before you start the contour rotation, select the contours to be rotated.
Access the option by:
Define the center of rotation and the angle by which the contour will be rotated graphically or by entering the vector coordinates in the Rotation dialog.
If Copy is selected, a new object is generated at the target location for rotation (the original object remains in its place). If this option is cleared, the original object is rotated to a new place.
