How to get the centroid to the bottom of bounding box.

[adel.albloushi]

create the bounding box and get the lowest z value, let’s call it Zmin

then deconstruct your centroid into x,y,z

reconstruct a point with x,y,Zmin

Thanks for solving it, i also tried use domain y to offset its bottom. this method is useful set bounding box to any 27 points of bounding box.
