I created a roof drain family using the "Generic - Face Based Family" template. Once loaded into a model I used a section box to inspect how it would effect the surface it is hosted on. When the section box runs through certain areas an unknown spherical mass appears. I did not create this mass nor do I understand where it could be coming from.
It appears that it could possibly be from the revolve extrusion used to make the roof drain cap, however I do not understand why it would be doing this.
So I ask, where is this spherical mass coming from and why would this being happening?
