This program has three commands - Wplan, Oplan and Roplan.
Wplan : sets the UCS and view back to the original world rotation.
Oplan : the user is prompted to select two points, an origin point and a point on positive portion of X-axis. The UCS and view will be rotated to be orthogonal to the points picked and the view is then saved.
Roplan : restores the saved orthogonal view.
