removeprim

int  removeprim(int geohandle, int prim_number, int andpoints)

geohandle

A handle to the geometry to write to. Currently the only valid value is 0 or geoself, which means the current geometry in a node. (This argument may be used in the future to allow writing to other geometries.)

prim_number

The index of the primitive to remove. If this is -1, the function does nothing.

andpoints

If this is 1, the function will also delete any points associated with the primitive that are not associated with any other primitives.

Note If some primitives are being removed with andpoints set to 0 and some are being removed with andpoints set to 1, all of the primitives with andpoints set to 0 will be deleted before all of the primitives with andpoints set to 1.
