Hello Christophe,
In the mean time I've read some more about the IGES format. It seems it
is able to encode information in both solid and BREP modes. The default
export of BRL-CAD is solid mode. When I let use faceting to generate
the IGES model it all works. Unfortunately the model is then completely
built with triangles, but it will do the job.
Thanks for your help an great application,
Mark van Doesburg.

If I uncheck the "Remove small edges/faces from OpenCascade models" in
Options->Geometry->General the file loads without warnings, but the
models appears to be empty...
As a general rule, try to avoid IGES files: they don't contain the
topology. If at all possible use STEP files instead.
