Overlapping area of two CurveLoops (from floors)

[wouter.hilhorst]

Hi,

I`m working with the revit api in C#. I want to find the intersection between two closed CurveLoops in the XY plane. This intersection should be a third Curveloop in the same plane.

With this I want to find the overlapping surface of the surfaces formed by the lineloops before I use these lineloops to place elements (floors) in Revit. I found the Intersect Method, but this only seems to work on curves.

Is there a way to do this with the revit api?

Yes. The Revit API does not provide any support for 2D Boolean operations between curve loops, so you will need to make use of an additional third-party library for that, or implement your own algorithm. The Building Coder shares some suggestions here:
