Changes
#The Work Plane dialog opens up at the lower right corner of the screen.
#Use one of the following three methods to establish a new work plane.
In all the three cases above, a translucent plane appears showing the location and orientation of the new work plane. The transverse axes (local X and Y axes) of the new work plane are displayed in red and green colors, respectively. A new "User Coordinate System (UCS)" is established on the new work plane. In the work plane dialog, you can see the world coordinates of the center of the UCS and its rotation angles with respect to the project's world coordinate system (WCS). From this dialog, you can change both the center coordinates and the rotation angles of the new work plane. Note that the visible size of the work plane is purely for visualization purposes; otherwise, the work plane has infinite extents. You can also change the '''Color''' and '''Transparency''' level of the work plane.
