Dear friends, as shown in the screenshot, there are 2 conduits in the existing revit, and they have intersection points P1, P2, and P3 with the outer contour of the beam, how to get the number of intersection points between a single conduit and the outer contour of the beam, thanks.

thanks a lot。

Dear partner, another question: how to tell that a point P1 is inside a three-dimensional entity (such as a beam, column, wall, etc.).
