- Which parameter do you need to change in the familyinstance (you changed the family to a round opening)?
I want to change “IND_Diameter”. Yes in round openings. “IND_Thickness” is ok, i think 
- Which familyinstance do you want to place? Is it inside the project you send?
Yes, family is inside. If you prefer i can send only the family 
If you could show me the path…
Thats weird, I try to check it today.
Ok i think i have an anser. I used bimorph node to get curve of intersection and now i think all its ok. But i will test it tommorow. You can see the difference between the curves lists.
Hi there @PrPr and @jw.vanasselt
I have tried your graph, and it worked very well, so thank you for that, but is there a way, to read information from the wall as well, to write it back to the family, for instance fire ratings and so on. from the wall ?
