Should the triangular face be extruded along the direction of its normal vector?

Hello, I have another question:

1. Are there any functions in meshlib that can extrude a triangular face along its normal direction, transforming it into a triangular prism mesh?

This is similar to the effect in Blender where extruding a face along its normal direction transforms a triangular face into a triangular prism.

Hello!

This extrude sample selects two faces and extrudes them in +Z direction. In your case you need to select only one face and use its normal as a direction.

Thank you very much.

I want to extrude two faces to a certain length to verify their normal directions, and then determine whether the two extruded meshes intersect, thus checking for overlap between the original two faces.

Do you think this approach is suitable?

Hello!

This approach should work in some cases but it seems to be too intrusive (changing mesh is not free operation and should be avoided where possible)
