Hi,
I have create a cutter family and place in beam :
Now, I want get to the faces of this element. But when I try, I don't found...
I explore with Revit Lookup and the result is same...
How find the faces of a cutter family ?
thanks for your help !

Dear Charles,
Thank you for your interesting query.
I assume you wish to retrieve the faces of the wall that delimit the whole created by the cutter family instance?
This is not completely trivial, I'm afraid.
I can think of two ways:
1. Grab the entire solid geometry of the wall with the hole in it. Iterate all the faces and store them. Temporarily remove the hole from the model. Grab the solid and iterate and store its faces again. Determine the difference between the two lists of faces.
2. Grab the entire solid geometry of the wall with the hole in it. Determine all the profile curves of all its vertical surfaces (assuming your wall is vertical). One each vertical face, determine all the inner loops. For each inner loop, determine all the attached faces. All of those that penetrate the wall are the ones you are after.
I hope this helps.
I am sure many other approaches are also possible.
Please do let us know how you end up solving this.
Thank you!
Best regards,
Jeremy
Hi Jeremy,
thanks for your answer. I have test your ways but it's not really the result that I want !!
For explain my target, I want insert another family in the face of my cutter family !!
I think, I must search another way with the position of family instance
If you have another idea !!
thanks
Determine a point in the middle of the hole, e.g., the cutter family instance insertion point.
Shoot a ray from it through the wall, for instance, along a horizontal ray parallel and vertically above the wall location line.
Determine the intersected face.
Have fun!
Cheers,
Jeremy
