@arne2320 said: Hey guys I am currently trying to make a hole inside an entity with the ruby api, but can't find the rigth way to do it, I have tried it by creating a circle, placing it on top of the entity and then removing it but this doesn't seem to work so does anybody have an idea how i can do this? Thanks in advance When you place the circle on a face, it will create a new face inside the circle. If you remove the circle you remove this new face as well. So place the circle and remove the face inside instead of the circle. [image: eY4V_Hole.gif]
