Changes

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. This will change the location and orientation of the new arbitrary work plane. Once you are content with the location and orientation of the new work plane, you can also change its visible size. Note that the visible size of the work plane is purely for visualization purposes; otherwise, the work plane has infinite extents. You can change both '''Length''' and '''Width''' of the work plane separately. You can also change the '''Color''' and '''Transparency''' level of the work plane.

Once a new work plane is established, the mouse will be bound to that plane. In other words, the cursor will move freely on the surface of the new work plane. The '''Status Bar''' now reports the "User Coordinates" of the cursor position as opposed to its "World Coordinates". The status bar also shows the word '''User''' in front of these coordinates. You can switch back to the world coordinates at any time by double clicking the word '''User''', which changes it to '''World'''. Double clicking once again toggles the state back to the user coordinates. Any object that you draw on the new work plane will have its local X and Y-axes on this plane, and its local Z-axis normal to the plane. While a non-principal work plane is active, you can always summon its dialog and change its properties. To do so, click on the '''Work Plane''' button in the '''View Toolbar''', or select '''Menu [[File:larrow_tn.png]] View [[File:larrow_tn.png]] Work Plane [[File:larrow_tn.png]] Arbitrary Plane''', or use the keyboard shortcut '''W'''.

{{Note|A new work plane will stay in effect until to switch to one of the three principal work planes.}}
