I wanna place families by picking a face. Everything works very fine so far.
Select face --> I create point grid on face --> with FamilyInstance.ByPoint I get my Families on the face.
Now my problem is:
If the face is a face of a Slab, there is also a Column or a wall. At the moment my Families ignore the columns or walls.
I am looking for a Dynamo Workflow, to automatically delete Families when they collide with a column or a wall.
The picture shows mainly how it looks like.
Thanks for all your help!
