FamilyInstance is not place on face or surface


i use node springs.FamilyInstance.byFacePoints for place family on face or surface, but i don’t know what the problem for place family.

I think that should work

dumb question- it is a face based family- right ?


yes it’s Face Based Family

try it without the flatten nodes- your lists are already one dimensional

Thanks for reply

yes, that;s right.

but i Want select wall then i get Surface after filter of the element as INPUT(Face) of Springs.FamilyInstance.ByFacePoints.

and i get point by Solid.Centroid and then set point it’s my required that output as INPUT(Point) of Springs.FamilyInstance.ByFacePoints.

so that’s my Problem
