viju Posted July 10, 2006 Share Posted July 10, 2006 hi all, i am very new to max and have a problem. when i import models with curvature from autocadd to max, they appear fragmented and the texture applied on them behave in a different way altogether......i have tried to increase arc and circle smoothness and segment number in polyline but nothing seems to be working HELP!!!

STRAT Posted July 10, 2006 Share Posted July 10, 2006 you need to break the autocad circles into smaller segments before importing into max. Link to comment Share on other sites More sharing options...
tecton3d Posted July 10, 2006 Share Posted July 10, 2006 you need to break the autocad circles into smaller segments before importing into max. strat, are you talking about xploding the arc/circle? Link to comment Share on other sites More sharing options...
STRAT Posted July 10, 2006 Share Posted July 10, 2006 you cant explode an autocad arc or circle. Link to comment Share on other sites More sharing options...
tecton3d Posted July 10, 2006 Share Posted July 10, 2006 alright ~ I must have been thinking about an old version or just haven't had enough coffee yet : ) so how do you "break it into smaller segments"? thanks Link to comment Share on other sites More sharing options...
STRAT Posted July 10, 2006 Share Posted July 10, 2006 with the BREAK function Link to comment Share on other sites More sharing options...

ajvbochove Posted July 10, 2006 Share Posted July 10, 2006 I'm not an expert, but I think the solution to your question is.... Import as autocad.dwg Tab Geometry Increase Curve steps. or Increase Surfuce deviation for 3D solids Link to comment Share on other sites More sharing options...
JamesTaylor Posted July 10, 2006 Share Posted July 10, 2006 when importing to max you should get a pop up dialog box with a variety of import settings. reduce the "Surface deviation for 3D solid" or increase the curve steps ( i think the curve steps may be for 2d line work) Link to comment Share on other sites More sharing options...
TheAllusionisst Posted July 10, 2006 Share Posted July 10, 2006 For solids with curves in autocad increase the 'Facetres' (that is what the command is called if my memory serves me correctly) to 4 or so, you may want to play with it to get a mesh that has the curvature you want without too much density in your mesh. That command is for solids not 2D polylines, arcs and circles, so if I missed what your question was, I apologize. Link to comment Share on other sites More sharing options...
Ray Posted July 10, 2006 Share Posted July 10, 2006 Surface deviation for 3d solids to 0.013--you can also play with the smooth angle, but be careful with this one. Link to comment Share on other sites More sharing options...
gfa2 Posted July 10, 2006 Share Posted July 10, 2006 when importing to max you should get a pop up dialog box with a variety of import settings. reduce the "Surface deviation for 3D solid" This is the correct answer. I fought this for quite awhile. Lower this setting from 1.0 to 0.1 and everything will be smooth. Link to comment Share on other sites More sharing options...
roarke Posted October 28, 2006 Share Posted October 28, 2006 Mr. Garl Allison....thanks for your confirmation regading smoothness....thank you so much! Link to comment Share on other sites More sharing options...
e-YELLOWCABS.COM Posted October 28, 2006 Share Posted October 28, 2006 the autocad variable FACETRES is set by default to 0.5. You've to change it to 5 to 10 BEFORE creating your solid, you should see differences... Link to comment Share on other sites More sharing options...
The_architect06 Posted October 28, 2006 Share Posted October 28, 2006 mate..you just have to change the settings in autocad not in 3ds max in autocad just go to : options > Display on the top right of the screen increase the arc smoothness & increase segments in a polyline curve... this always works..but also will much increase your file size Link to comment Share on other sites More sharing options...
jvlive Posted November 7, 2006 Share Posted November 7, 2006 thanks, Gary for pointing out the correct answer. just encountered this problem, and i found the solution quickly. i love cg architect. Link to comment Share on other sites More sharing options...
itoocson Posted November 7, 2006 Share Posted November 7, 2006 when you import Autocad files, in the configure dialogue box check the import check force 2 sided faces or something like that, or use turbosmooth. However, it is more advisable to change all your curves in Autocad into polygons before extruding them. This will also lessen the polygonal faces your computer has to render, because curves in autocad are actually polygons with microscopic faces. Using polygons minimizes the face count. You have to do some experimenting as to how much segmentation is needed without your curves showing the segments. Link to comment Share on other sites More sharing options...

Viju the simple way is to use (Facetres) and (isolines) Paramaters in autocad change Facetres from 0.5 as standard to 5-6 and isolines from 4 to 100 and then export to 3Dstudio max as 3ds.and enjoy curves and arcs and ellipses . ?Try that & let me know!

tarek.saade Posted May 8, 2007 Share Posted May 8, 2007 Hello do it just before exporting to 3ds format! Link to comment Share on other sites More sharing options...
kippu Posted May 9, 2007 Share Posted May 9, 2007 i usually used to just go really close by and select the arch and export it to 3ds ...but that was when autocad had the 3ds option .... i miss it Link to comment Share on other sites More sharing options...

MrCAD Posted May 9, 2007 Share Posted May 9, 2007 well as others mentioned... Facetres variable will do the job but if you export it to a 3ds file format. Meher http://www.mr-cad.com Link to comment Share on other sites More sharing options...
