Triangulation of an entire TopoDS_Shape

I'm using 7.4.0. I'd like to take a TopoDS_Shape and convert it to a reasonably coarse triangulation- one in which smaller faces are entirely glossed over. Imagine a shape which includes everything down to the threads for a small screw; ideally I'd like to have a triangulation which ignores those threads since they are dramatically smaller than the overall shape. Does OpenCASCADE provide such a function? I understand BRepMesh_FastDiscret​, now deprecated, was for a similar purpose. Can you provide an example of the recommended replacement?
