Attempting to convert two IGES files made with Autodesk Inventor 2011. Both are simple extrusions of a single closed curve. One closed curve is an ellipse, the other file is a squiggly NURBS. Both were exported with Autodesk Inventor 2011.

I ran the following command from the command line:

./brl-cad/brlcad-7.16.10/src/conv/iges/iges-g -o ellipse_iges.g Ellipse.igs

The output was the following:

I then ran the following to try to convert the other file:
./brl-cad/brlcad-7.16.10/src/conv/iges/iges-g -o squiggle.g squiggle.igs

This was the output:

I am running Ubuntu on a 64 bit machine. The binaries were compiled from source.

Attached are the two IGES files that I was attempting to convert.
