Intersection between two faces

Akhilesh Thothara's picture
Forums: 

Hello everyone,

I am trying to find whether there was an intersection between two faces. I need the result True or false. For this intersection, I used GeomAP_IntSS for finding the intersection.

But the problem is, even two faces doesnot intersect each other, it returns  True.

Can anyone help me why is this happening?

Thnak you

Dear Akhilesh,

You can use GeomInt_IntSS class for intersection of surfaces (like it is implemented in “intersect” Draw command) or IntTools_FaceFace for intersection of faces (like in “bopcurves” Draw command). Both commands return the result of intersection (not only True/False) if it has been found.

Thank you for the reply

I imported a STEP file in pythonocc. In that file, I would like to know whether two faces of two different parts lie one on another. How can I check whether the two faces touch each other?
