The Performer FAQ describes the DXF loader as "incomplete". Your
best bet is to convert the DXF file into Inventor format, and then
load it using the new inventor-savvy version of 'perfly'.

The DXF->Inventor converter is in:
ftp://ftp.sgi.com/sgi/inventor/1.0/DxfToIv.tar.Z

The new inventor-savvy perfly is in:
ftp://sgigate.sgi.com/pub/Performer/src/pfiv1.3.tar.Z
