Hi! I'm new with opencascade. I want to get triangles and vertices from STEP and IGES files but I don't know what is the best way to get the triangulated surface from those types of files.

Thanks in advance!

Hello Germán,

Reading STEP or IGES files can give you topological shapes that do not contain any triangulations. To create such, these shapes need to be meshed with help of a meshing algorithm, for example, the standard BRepMesh_IncrementalMesh or a more advanced Express Mesh. When a shape is meshed, you can explore triangluations (of type Poly_Triangulation) of its faces using some of the available exploration tools, like TopExp_Explorer.
