Geometry Intersection Error - inconsistent edge-face relationships

does anyone have any idea why this error appears, and how to solve this problem?

I am trying to intersect solid with plane, soo i can get area of the intersection surface, in some cases i get full results without any errors, in other cases some solids return this error, but when i go and check families, everything seems OK.
Thank you for your help :slight_smile:.

Hi Jan,

Could you post full screenshot of your graph. Partial screenshot will not help others to understand your problem.

I think it will be much easier if i just post my dynamo definition and rvt project file :slight_smile:. Sadly rvt is too big to upload it here, soo i will post link to dropbox folder…
