Dear,

I read everything and tried a lot of test but i don't understand the follow behavior:

1) CopyToPoint with a Circle as Source and a Grid as Target.
The result is perfect, the circles as replicated to each points of the grid
2) CopyToPoint with a PolyDraw as Source and a Grid as Target.
The CopyToPoint node correctly replicate the Polydraw to each points of the Grid but on a difference position of the scene. WHY?

I don't undertsand what I missing. The Houdini manual doesn't mention that I need to set something (attribute, for instance) when I want to use a PolyDraw as source of CopyToPoint.
Where am I wrong?

Thanks for the help.

Is your polydraw centered around the world origin?
You could try to append a TransformSOP right after the polydraw and in there click on "Move centroid to origin" and see if that comes closer to what you expected as a result.

Yes! Thanks a lot :-) ... it works ... now I can solve similar future issues even if I didn't understand WHY! For witch internal reasons Houdini needs this "Move centroid to origin" (not documented on the online manual) in a transform node after a PolyDraw and not for a Circle, Cube, Sphere o other nodes.
I'd like to understand.
Ciao
