hi everyone, Trying to place family by faces of linked file. but I’m not able to set rotation properly. also I’m using surface areas to get top surface, so please suggest the easy way to select top surfaces.
Hi @vishalghuge2500 seems something wrong with the familys origin, but you could try something here…
arh you want them to slope ?, then i think you need to edit your family and uncheck for"always vertical…without that it isnt even possible manuelly
yes I have tried this one also but not able to place them correctly.
also tried with familyinstance.ByFacepoints
I think in that case i would try made the family as 2 point adaptive and could probably work as you say with .by face point, if you edit the family…
Edit i have give it a try if you uncheck always vertical and check worplane based in your family…something here works…
Hi Christian…no my example was in 2023 …is that the newest version ? the newest one works in 2024…not sure its called 5.0…allright see now you dont have the latest version as you get the warning int 64
ok, I suspected that it was a dumpling still on my side,
am going to down in package version then thank you
edit:
it worked well except that I had forgotten to filter the surfaces (in badger mode I am today) 
Cordially
