Bearer - Element Faces gives Error when placing family

Hi everyone :slight_smile:

I´ve got a problem with the “Element.Faces” command and some bearings with round openings.

Element.Faces works fine until I place a family in it with round openings.

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.

Thanks and kind regards,

Element.Geometry into Geometry.Explode may work as an alternative.

Unfortunately Element.Geometry gives the same Error as the Element.Faces Node when the round opening is placed in the bearing.

Can you upload a sample rvt with one instance that recreates the issue?

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 :slight_smile:

Thanks and kind regards,

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.
