Very interesting solutions. I also prefer scale/tweak surfaces over Offset command, because Offset gives more complicated surface and curve structures, especially when Offset inwards.
Hi Pashkuli, I have to say I use both methods. Actually if you're doing a trim surface you can use the loose option in Offsetsrf. This won't be a 100% accurate offset, but it will give you a clean surface that can be used to trim. And like you I do also use copy/paste scale quite often for curves. Cheers.
@@marklandsaat3696 Also I noticed during all those years that Rhino's MatchSurf command is rather not so intuitive even for simple tasks. Have you tried: ShrinkToEdge command after trimming a surface, regardless of the trimming method used (Offset or Scaled cutting objects)? Then eventually rebuilding the edges? Yes, this way you loose the untrim opiton for later teweaks, but still might be giving a better result at the end. XNurbs gives very well optimised solutions, also VSR (Rhino 5 only, not sure if VSR will work in Rhino 6/7) is quite a leap forward in surf matching. Using MoveUVN command in Rhino is fine but it is not precise (in terms of individual CVs control) to achieve true G2 (within file tolerance).
@Pashkuli Keyboard, yes I agree that sometimes the result is not completely intuitive. Thanks for pointing out ShrinkToEdge, I have to admit that is not a command that I'm familiar with. I will have to play around with that. I always put my primary surfaces on a separate layer before I start final trimming and blending for exactly the reason you mention. If you shrink the trimmed surface, you can not go back to the original surface, but if you have the original on a separate layer it's easy. You can use the boundary edges of other blends to trim the primary surface. I have VSR, but unfortunately it only works in V5. It's a great tool, but it's a pain to constantly go back and forth between V5 and V6. XNurbs doesn't replace VSR, but I really like having it as part of my toolbox. Cheers.
Very nice tutorial. Thanks for sharing.
Thanks @PC Sim
