BTW, I've been doing some research on this SAT file format. It is a text format used by the ACIS 3D kernel (used by many apps). Apparently the SAT spec has been released by Spatial, Inc., but I couldn't find anything besides a 30-page pdf, which seems quite incomplete. OpenCASCADE has written a SAT parser/importer, but this module is not free AFAIK.
Anyway, this is not LibreDWG's business. We'll just read the SAT chunk, and then the app will handle it. -- Rodrigo Rodrigues da Silva PoliGNU - Grupo de Estudos de Software Livre da Poli/USP FSF Associate Member #7788
