Importing AutoCAD - MAX problems....

[Kassner]

Hi everyone,

 

Does anyone has a problem like this?

I tried to increase the number of contour lines per surface on objects and higher values of smoothing angles before importing but I always get the same result.

Anyone?

 

Thanks,

Kassner.

Hi,

 

Those settings affect only the display resolution, not the actual mesh quality. In order to get smooth curved surfaces in acad you should increase the surftab1 and surftab2 values so you have more faces, but you have to do it before modeling the object, because those values can't be edited in acad afterwards.

you need to set facetres to a higher value for extruded curves.

 

surftab 1 and 2 only apply to meshes

 

hope it helps

you should be meshing curved surfaces up anyway instead of extruding them in autocad.

hi kassner,

in the "import autocad dwg file" dialog box (in max) go to "acis options surface deviation" field, and decrease the value untill the desired result....this must correct your problem.

i use to work in meters (units) and the value that fits my needs is 0.005 .

 

best to you,

nuno

Now it works fine!

I used higher values of FACETRES (8 to 10) when I generate 3DS in AutoCAD and 0.001 for ACIS DEVIATION to import DWG in MAX.

Thanks for all replies!
