I am trying to find the min distance face in Geometry B of a point A. I found out there are two method (maybe more?) to get that, one is min distance and another is xyzdist.

My question is which one is faster as my geometry B could be very big.

Thank you in advance for your insights.

Oh I found out that Ray node is finding min distance "point" and xyzdist is min distance "surface"... which make Ray node much faster.

Anyone knows other method of finding min distance surface/pirm? xyzdist is a little slow .
