ConradSimpson Posted March 12, 2012 Share Posted March 12, 2012 Refer to this thread as background: http://forum.123dapp.com/123d/topics/how_to_i_slice_a_3d_into_a_2d_newbie_question I am a noob. Please do not assume I know much about AutoCad--honestly about an hours worth is all I know. I do have a couple of reference books. Here is the problem: I have a 3D model in the format of 123D (Freeware by Autocad). I converted this to .DXF then imported into AutoCad 2012 and saved it in .DWG format. The 3D model is of a crocodile. I wish to take cross-sections of this model so to generate width traverse sections from the longitudinal head to the tail of the animal. This is so I can form a model of the animal out of wire. So how to best do this? Apparently the model in .DXF/.DWG became a 2D "mesh" so I must first convert to a solid? (I say 'became' because originally it was in .123c format, but my version of Autocad 2012 does not recognize this format, so I had to convert to .DXF, which I believe rendered the 3D into a 2D mesh) Or can AutoCad take a 2D "mesh" and generate cross-sections? Top-down general advice is good but even better is a detailed step-by-step explanation of how to do this. I did "select" the entire animal and tried to make a "solid" out of it using a button icon on the ribbon panel (as opposed to a "surface") but I think I stopped prematurely--there was no progress bar so hard to tell. So then I guess you generate a cross-section once you generate the solid by doing what? is there a dialog box that ask for your end points (of the plane, defined by a line?) I appreciate any help I can get. I will check this thread in a few days as this is not urgent. Thank you very much. Quote Link to comment Share on other sites More sharing options...
Randolph Posted March 14, 2012 Share Posted March 14, 2012 Remark remarked in another thread: "AutoCAD 2012 has a command that converts a mesh to a solid (CONVTOSOLID). " If this works with your crocodile, you can then use the slice and solprof commands. Quote Link to comment Share on other sites More sharing options...
3D generator Posted March 20, 2012 Share Posted March 20, 2012 You might have better luck sticking with Autodesk 123D. They have a new app called 123D Make that will convert 3D designs into 2D patterns for assembly. Quote Link to comment Share on other sites More sharing options...
f700es Posted March 20, 2012 Share Posted March 20, 2012 Why did you save as a dxf 1st and not just as a dwg? Quote Link to comment Share on other sites More sharing options...
