Our STL to IGES product can convert STL to IGES surfaces. Two adjacent planar
triangles can be combined into a quadrilateral, reducing the surface count.
Since the vertices of the triangles in a valid stl file match exactly, most
solid modelers can easily match the surface edges to make a solid. The problem
is the massive number of surfaces. Most engineering brep modelers do not
expect to import tens of thousands of surfaces. So the import and sewing
operation can take a Long time, and require Lots of memory. The result tends
to be large.
Faceted modelers, generally used in the visualization and rendering markets,
have a much easier time dealing with lots of polygons.
STLtoIG is part of our IGtoSTL package, and is also available separately.
