How I can create custom POINT CLOUD?

[Anonymous]

Hello,
I know that ArchiCAD supports two formats for point cloud, and imports them as GDL object. But I need to create custom point cloud from my Add-On in ArchiCAD.

Is that right that I have to create a library part (.gsm file ?) with points definitions, and then import it as API_ObjectType into current document?

Then the question is how can I programmatically generate this gsm file, with set of colored points? Is there any example project showing geometry creation and storing it as object into gsm file?

Also, I've seen following function for 3D point creation, but not sure if it is what I am looking for.

Geometry::SetCoord3D(const Coord*  pC, double  z)

Any help would be very appreciated,
Thanks Valeria.

Is there any way to create a point element in current document in ArchiCAD?
I see that API_Element accepts different geometry primitives, but nothing for 3D point.
