Hi SYSOP, I'm really very satisfied with 3DS and if they're integrating raytracing I'll get happy for the rest of my life ( 2 months !!!). As a Industrial Designer I rely more on perfect modelling & design drawings & model production, so I modell on CAD/CAM systems like Bentley Modeller. But there is one big problem, most of this packages use nurbs and acis based surface boundary representation ( which is really great ! ). But since 3DS can't import IGES, VDAFS or similar File Formats you're always stucked to make animations and rendering on your system. Isn't there any solution who to handle or exchange such formats? Great to hear from you!!!! OLLIPOP———————————————————————— ———–OLLIPOP

Thanks for your response, But Bentley doesn't export polyface meshes when they are trimmed or booled. That's the real bottle neck. Of course I can export simple extruded surfaces, but when designing an automotive design you use sparely extrusion or rotation. With Bentley I can project curves on surfaces etc. and that boundary surfaces can't be exported in DXF polygon format. This seems to be solved only by VDAFS or IGES. Oh I hope that 3DS will sometimes support one of this formats. OLLIPOP———————————————————————— ——–OLLIPOP

(didn't know youw ere doing that). >> That's the real bottle neck. << yes, it is. >> Of course I can export simple extruded surfaces, but when designing an automotive design you use sparely extrusion or rotation.

This seems to be solved only by VDAFS or IGES. << you are correct. this is a dilemma. however, Microstation has had Nurbs in it for a while and the 5.x (even 4.x_) NEXUS stuff was capable of fairly reliable polymesh exports. do you have Microstation? >> Oh I hope that 3DS will sometimes support one of this formats. << somehow, i think it will eventually as they seem to be getting into all sorts of apps as standard. -dave

Maybe the Autodesk IGES translator is the final solution. I've got to checkit out, or buy an SGI / Alias ( They import IGES and convert nurbs to meshes) Huastaluego OLLIPOP———————————————————————— ———-OLLIPOP

Hi Dave, What about a demo version? I know this isn`t the gentleman like way, but I would play your beta tester! Huastaluego OLLIPOP
