is it possible to transfer primitive attributes to points ?

I placed points in the center of each primitives of a mesh using a popnet “Prim center (ordered)” source , and I would like to copy the area primitive attribute (created with measure sop) to these points .

I'm trying to do that with an attrib transfer node , source group type = primitives , destination group type = points , but it doesn't work so far …
I have the popnet in the first input , the original mesh in the second input.

?

Ray SOP seems to work, but feels a bit dirty.

works fine … thanks !

Is not this what the Attrib Promote is for?

Well, not exactly. The promotion works between elements where one is the “member” of the other, e.g. points and the primitive they are part of.

Here it's completely separate geometry we need to transfer the attribute to.

Hey, there. If your primitive and point orders match (which they might if you used prim center ordered and aren't creating any more points than primitives), you can use the “prim” expression to copy the attribute. i.e. use prim(“path_to_primitives_sop”, $PT, “area”, 0) in an Attribute Create. See the attached hip file. Cheers!
