STLParser

Parses STL files, and returns a Polyhedron. Note, STL comes in two flavours, binary and text. To distinguish between the two, we check the first 5 bytes, and if it reads solid, then it is assumed to be an ascii file. However, I have seen binary STL files with an (erroneous?) header. In this case, use parseBinaryFile, instead of the more usual parseFile (which attempts to guess the flavour).

I use STLParse when I want to take an existing model created by somebody else, and play with it from within FooCAD.
