great thanks. Now I have another question. Is it possible to create a true nurbs object within C4D? I suppose it would be done using splines. But its it possible to create geometry between splines?

Just curious.

So in my Message() for my tool plugin I have the following code.

Where if say's GePrint ("Subdivide Button Clicked"); I would instead like to execute the DoCommand() member. in that is the following code.

You should just call DoCommand() where you have that GePrint() in Message().

Save yourself unnecessary variables and wasted time and just do:

PolygonObject *objPoly = ToPoly(mdat.doc->GetActiveObject());

This is the error I get now.

error C2660: 'SculptTool::DoCommand' : function does not take 0 arguments

any thoughts?

Well, I hate to be obvious but you need to fill and send the ModelingCommandData& mdat argument for your DoCommand() function.

LOL..   obviously the obvious eludes me some times. HAHA..

Do I fill it the way it is declared?

like this.

DoCommand(ModelingCommandData &mdat;);

or do I need something else in the parenthesis?

LOL. thank you for you patience with this noob.

Okay. so now it calls the DoCommand function but as soon as it does, C4D crashes out...

Do you see anything in this code that would cause C4D to crash?

After you get objPoly, check that it isn't NULL:

if (!objPoly) return FALSE;

Also, make sure that the mdat.bc is set to a BaseContainer. I'd do this in Message after declaring mdat. Declare a BaseContainer and add it:

BaseContainer bc;
mdat.bc = bc;

You may also want to set your input BaseContainer value (HYPERNURBS_SUBDIVISION).

and this is the error.

I assume there is more I have to do to the basecontainer.
