I don't know... Gmsh's primitives are rather simple, so it shouldn't be
too complicated to import classic things (for example, take a look at
gmsh/utils/converters/; also, there is some initial code for STEP import
in gmsh/Geo/StepGeomDatabase.cpp). But Gmsh still misses (or only
partially supports) a lot of advanced geometry features (nurbs, trimmed
patches, etc.).

IMHO, the best way would be to import a "meshed" geometry (a la STL),
and enhance Gmsh's ability to deal with that...
