Get 3DSOLID structure and data out of ACAD

[Anonymous]

I would like to know if it is possible to exploit 3DSOLID data from DXF
file.
and how to do ?
I'm writing an application which has to to get vertices and faces from a
3DSOLID.
Is it right that ObjectARX is usefull to do these things ?
Is it possible to use *.arx file from a classical MFC application ? (or arx
file can only be used by ACAD ?)

Thank you in advance for your answers.

i have written lisp code to extract points from a 3dsolid or body without
exporting any files. if you tell me more about how you want the information
extracted and returned by the application i may be able to help you

Have a look in the FAQ:

Yes. ARX or LISP or VBA.

only inside. An ARX is just a DLL with a tricky runtime C++ custom class
loading scheme.

Why did AutoDESK encrypt their dxf records for ACIS objects?
Is there a legal reason for us not to try to decrypt the information?
