josefo Posted May 6, 2009 Share Posted May 6, 2009 Hi When i do for example a cilinder and save like DXF, appears: 3DSOLID And a code that i want to decode, Can somebody help me?

ReMark Posted May 6, 2009 Share Posted May 6, 2009 josefo: Welcome to the CADTutor forum. You've posted your question in a rather odd location (Introduce yourself). None-the-less, as regards your question, you must start with the basics.

ReMark Posted May 6, 2009 Share Posted May 6, 2009 Despite being written about Release 12 this extensively detailed article covers the structure of a DXF file. http://www.martinreddy.net/gfx/3d/DXF12.spec Quote Link to comment Share on other sites More sharing options...
ReMark Posted May 6, 2009 Share Posted May 6, 2009 Another article from AutoDesk regarding DXF file structure (Release 2000): http://www.autodesk.com/techpubs/autocad/acad2000/dxf/index.htm Quote Link to comment Share on other sites More sharing options...
Tiger Posted May 6, 2009 Share Posted May 6, 2009 I moved your question to a more appropraite forum, and added code-tags to your post to make it more readable. In the future, please post your questions in the most appropriate part of the forum. Quote Link to comment Share on other sites More sharing options...
SEANT Posted May 6, 2009 Share Posted May 6, 2009 I recall some attempts at decoding the dxf reference of 3dSolids. Here is a thread hinting at that process from the VBA side of things. http://www.theswamp.org/index.php?topic=16754.0 Another option is to analyze the solids via the SAT file acquired via an acisout command. Here are a couple of links that discuss the capabilities of that option. http://www.theswamp.org/index.php?topic=25855 and http://www.theswamp.org/index.php?topic=25614 towards the bottom.

bahrhamid Posted September 8, 2012 Share Posted September 8, 2012 Hi there, I have a sample dxf file that includes a Box, a Cylinder, a Pyramid, a Sphere, a Torus, a Cone, and a Widget. I have loaded that ASCII file in MATLAB and looked at the ENTITY part of the dxf reference about 3dSolids to learn how to extract some details of objects. I couldn't find any group codes indicating the coordination of those objects. Could you please tell me in which part of the loaded dxf file I should find those details? Best Regards, Hamid.

bahrhamid Posted September 25, 2012 Share Posted September 25, 2012 Hi, I have forgotten to say that the objects are of type 3dSolid. 1) Does anybody know how to use group code value 350 that is a Soft-Owner ID/handle to history objects? 2) Does this handle refers to the point where additional data about entity 3dSoid objects are stored? Please point me to the right froum where I can ask my questions if they are irrelative to the froum contents. Thanks. Best Regards, Hamid.
