Excuse me, but before one can answer such questions, we need to clarify
something about IGES. IGES permits one to represent a variety of geometrical
1. As pointed out by Mr. Todd, the IGES file may contain a wireframe.
Wireframes are *ambiguous* and it is impossible to convert them to solids
automatically. Even an experienced CAD operator may derive the wrong model
without input from the designer.
2. It may contain a cloud of points. The problem, then, is in the domain of
reverse engineering. There are specialized tools for this.
3. It may contain a set of cross-sections. If they represent, say, a medical
model, then, again, there a specialized tools for this too.
4. It may contain a solid model represented as a Brep or CSG tree. Well, again,
the technology for facetting a solid model is an old one in CAD and
5. It may contain a description of a surface model. There is a lot of
literature on this one too.
And so on. As you can see, IGES can be used for several purposes, and there
is no single method to convert a generic IGES file to STL.
