Re: [libredwg] 3DSolid ACIS->SAT->

[Rodrigo Rodrigues da Silva]

LibreDWG does not parse the ACIS chunk into a data struct. We only 
provide access to an array with the acis data. ACIS/SAT is another 
format, independent from DWG. I've just found out that its spec has been 
publicly released, and sounds like one could start a new library =]

I don't understand 3D modeling in AutoCAD at all. I'm not sure if the 
ACIS used inside DWG is compatible with other ACIS implementations.

Please explain this "decode" a bit further. I can't understand what you 
mean with that. You mean that the ACIS data is "encrypted"?
