Bevel doesn't really work well, but maybe im doing something wrong. And i don't wanna fiddle with edges to manually build a bevel, cause i want to have the radii to have exact values. I am used to a solid modelling program (solid works) in which it is incredibly easy to round of objects, so there surely must be an easy way to do this kinda stuff in maya too right? is there maybe a tutorial at simply maya that deals with rounding of edges for polys (and nurbs)?thanks in advance. tiz

(I already set the anit-aliasing to production). Attached Thumbnails

Well, i found a way to get clean poly-bevels in Maya, which works for me. I didnt know about soften/harden normals, but fiddling around with that option is good to get rid of those weird "seams" i got on my surfaces. Also, on the corners of a cube, problems can be solved with merge vertices. It takes some time, but not as much as manually modelling bevels. besides, with the bevel tool, you can specify an exact radius. Oh yeah, i also tried the bevel tool from byron (www.byronimo.de). This plug-in makes clean chamfers. To make real rounded edges with this tool, you have to make multiple chamfers. This tool is free. theres also some sort of package with chamfer/bevel/split poly etc on offer on that website. Haven't tried that, coz it's not free. cheap me. But i saw on another site some movies which show those tools in action and it all really works pretty well. So if your looking for good poly-bevel tools, byron might have the solution for you. Still i guess when it comes to modelling objects with a lot of bevels, i guess i rather model in SolidWorks, then afterward import it into maya. It then needs some cleaning up (cause SolidWorks is a Solid modelling program instead of a surface modelling one) but for the most time it works well for me. tiz
