Hi,
obj should be PointObject and not BaseObject !
Use IsInstanceOf() to test this.

Exactly. A little addition:
To get your hands on the resulting point object, use the cache (obj->GetCache()). And if cache is NULL for some reason, try the modeling command MCOMMAND_CURRENTSTATETOOBJECT. In both cases, the result will be a point object (presumed, of course, that obj is a generator that creates point objects).

An even smaller addition:
Always check allocations and anything that returns a pointer for NULL as an error condition. It can let you know (if you use GePrint()) that something isn't doing what you expect without crashing.
