The New Surface command allows the creation of additional surfaces. Seven unique surfaces can be added, however adding a subsequent surface causes the first surface to be replaced by the eighth. Each additional surfaces removes the last surface on the chain and replaces it with the one before.
Select New Surface from the Utility menu in either Edit or Entry Modes. The following window displays.
The default name for the surface is "Current", but it can be changed by deleting the default name and typing a new one. You may also change the color of the surface data lines. Press OK to add the surface or Cancel to abort.
If more than seven additional surfaces are added, a warning displays asking if you want to proceed before the oldest additional surface is replaced.
Press Yes to add the new surface and replace the surface listed above, or press No to abort adding the new surface.
The layers of the first two new surface are not as extensive as other surfaces. Below are a list of the layers available on the first two new surfaces.
