Drawing Modes
Lathemaster supports 3 drawing modes. These modes determine how your current
tool is used.
Paint
This is the standard mode, it merely paints what the user tells it to.
Preserve (Registered Only)
Preserve works like the paint mode, except that when the item being drawn
intersects a prexisting shape, the prexisting shape is not erased.
Carve (Registered Only)
Carve, in effect, acts as an eraser. It only cuts away preexisting shapes,
it does not create new ones.
