help on points, lines, curves from sw to algor superdraw

i'm trying to transfer points, lines, and a few curves that represent
a welded aircraft truss fuselage from sw to algor superdraw. superdraw
will import dxf, iges, or cadkey files.

i can't get any of the above elements to export out of sw into iges.
is there some setting that must be changed, or is this always a
limitation of iges?

i have the solid model tubes, but i want to analyze them as mostly
truss elements. so i thought i'd just import the node points into
superdraw and build the truss elements there.

thanks for any help,

Flyboy,

This is kind of involved, but it should work

Create a parasolid of the part, or assembly. Read it back into SW. You now
have an acuurate solid with no history, or sketch data.

Create a 3D sketch, and place point entities at the referance points you
wish to use. Output "save as IGES", ("options"- 3D wire frame, output sketch
entities)

This will give you a wire frame model, as well as the sketch referance
points.

Regards

Mark
