We've recently fixed some bugs in the DXF loader related to how some objects
made up of PolyLines weren't being handed correctly.
Another thing to be aware of is that the object may not be within the cameras
line of sight. (Which by default points to the origin....objects at the
origin should so up). If you try loading the object with the NCSA Display
utility that comes with Portfolio, you can try using the "Back", "Front",
"Left", "Right", "Top", "Bottom" default camera angles to see if you can see
the object.
If that doesn't work, try sending me the file and I'll take a look at it.
