Everything works fine if there is no / if there are rectangular openings in the bearing. Seems that the bearing is not able to “work with” the round opening.
Does anyone know a workaround for such a case?
I need the exact faces of the bearing to place another familyinstance by face. For this reason I don´t just need the geometry.
Unfortunately I´m not allowed to send the files publicly, because they are owned by the company I work for. I sent you a private message with the files
Reviewing the privately sent file, you are using an ellipse as your opening, not a circle. Ellipses do not translate well between Revit and Dynamo. Swap the extrusion for a proper circle and you should be fine.
