Noise Posted April 27, 2004 Share Posted April 27, 2004 Hi When I import Autocad solids into Max 4.2 it triangulates the solids in Max causing an unnecessary large number of faces to be generated with no additional detail. Does any body know how to prevent this happening ? Thanks for your time. Regards N Link to comment Share on other sites More sharing options...
NEVIANS Cedric Architect Posted April 27, 2004 Share Posted April 27, 2004 hello... the problem is not MAX , the problem is Autocad DWG this DWG format triangulate in automatic ... :-( OBJ format can be exported in "quadrangle" but i known only one plugin for autocad to export in OBJ (wavefront format) and you must pay for it!! :-( Link to comment Share on other sites More sharing options...
Noise Posted April 27, 2004 Author Share Posted April 27, 2004 Thanks for that - I am sure that I have done it sucessfully before without the triangulation. Maybe it was a more current version of Max. N Link to comment Share on other sites More sharing options...
Ernest Burden III Posted April 27, 2004 Share Posted April 27, 2004 All data in MAX is triangles. If you see something that looks like a square it is really two tri's with their common edge invisible. Link to comment Share on other sites More sharing options...
kid Posted April 27, 2004 Share Posted April 27, 2004 like ernest said, everything is triangles. but if you don't want them all to show (they'll still be there) go into Edge sub-object mode, select all, and click on Auto-Edge. that'll make all the triangle strip edges go invisible. Habware have free .obj import/export plugins for max. can't remember the link off-hand but they might be on http://www.maxplugins.de Link to comment Share on other sites More sharing options...
hockley91 Posted April 27, 2004 Share Posted April 27, 2004 I've booleaned and modeled in Autocad and then imported into MAX 6. It appears that the problem has been resolved with this new release. I have no tessalation appearing at all when I import. It's about time! Link to comment Share on other sites More sharing options...
Noise Posted April 28, 2004 Author Share Posted April 28, 2004 Thanks for the replies guys. We are in the process of upgrading to 6 so, thanks Hockley for what I had intially suspected. Regards N Link to comment Share on other sites More sharing options...
IC Posted April 28, 2004 Share Posted April 28, 2004 I've had this problem in Max 6. It's not the number of polys that's the real problem, however, its the random way the normals face. Better to model in faces than solids. Link to comment Share on other sites More sharing options...
hockley91 Posted April 29, 2004 Share Posted April 29, 2004 IC, I just tried it again and it worked without any problems. I did some boolean operations on a box using spheres and boxes in Autocad 2002. I then imported that booleaned object as a .dwg into MAX 6.0 and had no tesselation occuring. I make sure my surface deviation is set at 0". I find that the objects imported are much smoother than the default setting. I had a lot of problems importing my plines into Max with the default setting.... Hockley91 Link to comment Share on other sites More sharing options...

Hockley91 Surface deviation at 0 is fine, but generates the most triangles. Avoid it when doing a large scene with lot's of curved surfaces in AutoCAD. The import of AutoCAD Solids into 3ds max 6 works fine and there are much less troubles as there used to be. Link to comment Share on other sites More sharing options...
Munz Posted May 2, 2004 Share Posted May 2, 2004 I thought this thread was going to solve a problem I have, but I didn't. I am working in Max 6 at work, and there when I draw a box it does not display the triangulation of the geometry but at home, I am working in Max 5 and when I draw a box the geometry apears triangulated on the screen. Is there a setting that I can turn off so I don't have to see the triangulation. I have search the help with no luck... thanks munz Link to comment Share on other sites More sharing options...
abicalho Posted May 2, 2004 Share Posted May 2, 2004 You're using DirectX. DirectX will show you the hidden edges by default, unless you disable it in the driver. Switch to OpenGL and give it a try. Alexander Link to comment Share on other sites More sharing options...
Munz Posted May 3, 2004 Share Posted May 3, 2004 Thanks I will give that a try. munz Link to comment Share on other sites More sharing options...
