Hi.
I I have a bunch of primitives and i am trying to create a point for each primitive and align each point to the corresponding y-min of each prim.

I can align to the center of each prim no probs but I can only align to the ymin of the 1st primitive( file attached i am assuming this isn't working because I am aligning to the y min of the whole object)

Any help would be greatly appreciated.

Cheers.

Try this:

string prim = itoa(@primnum);
vector bbm = getbbox_min(0,prim);
vector bbc = getbbox_center(0,prim);

addpoint(0, set(bbc.x, bbm.y, bbc.z));
removeprim(0, @primnum, 1);

Your original code refers to all the geo entering the wrangle, not per-prim unless you explicitly tell it otherwise.
