The Krump Filled Solid function is used to modify a filled solid by adding vertices to it, removing vertices from it, or moving one or more of the vertices about. To dissolve a filled solid, you must first "grab" the desired solid and then enter the key-strokes <EF>. The filled solid will be reduced to a set of perimeter lines. The lines may be modified using any of the standard editing functions.
To construct a filled solid, you must first "grab" the one of perimeter lines and then enter the key-strokes <EF>. The file will be scanned for a set of lines to define the perimeter of a closed region. The entire group of lines will then be compiled into a solidly filled area.
