Cut Only (Prestrip or Coal Removal)

This command is similar to Cut & Place. Cut Only removes a cut area in cross-section view from a surface polyline. The difference with Cut & Place is that this command does not place the cut area as a spoil pile. The cut area is just removed from the surface polyline for operations like remove coal. Try to stay away from a 90 degree face on the coal, AutoCAD doesn't like vertical faces (89 is entered below). The Type of Cut chooses between Coal (Key Only) and Prestrip (Non-Key Only). This setting is used in reporting and doesn't affect the rest of the routine. The same prompting and snap dialogs appear here as in the Cut and Place command.
