Using the clean mesh from K1 (makes a Mesh to Brep. i want to evaluate the surface area. Whatever surface you want to use for selecting faces, you can deconstruct mesh faces and test if the face center point (rough test) is on the desired side, or all corners (rigid test). BPA yields a mesh (open or closed) or more (open) depending on the topology and the search radius. So I would like to ask you if there is another way to thicken Brep without converting the Brep to a mesh object. I made this choice because I wanted to have surfaces with trimming data.
