removeattrib
int removeattrib(int geohandle, string attribclass, string name)
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.)
attribclass
One of "detail" (or "global"), "point", "prim", or "vertex".
You can also use "primgroup", "pointgroup" or "vertexgroup" to read from groups.
name
The name of the attribute or group to remove.
