Rhino3d v6 for Windows / Modelling Enhancements - Match Surface with History

[@evangeliadimitriou1177]

thanks!! soo muchh

[@yeasboy]

Very well explained and so nice feature fan of it.

[@luckyhappy65]

Really clear explanation! Thank you!

[@mokshud8302]

Wow its really Nice ..

[@jean77flip]

good tutorials mate. can i ask if you have any videos on working with meshes, subD, etc?

[@SimplyRhino3D]

Hi Jean, we have concentrated on NURBS rather than meshes because essentially that is what Rhino is all about. However Sub-D objects are being added to the Rhino WIP builds and we’ll be covering these in future tutorials as the Sub-D project gathers pace. Thanks for watching.

i've seen some on youtube regarding converting between meshes to nurbs back to meshes. it's fine if you don't. i will figure it out

Untrimmed edges only? Not up to Autodesk Alias standards yet, then, but very nice to see that perhaps in a few years, Rhino might actually be a valid Alias replacement! Is there a "project align" equivalent so you can project a surface onto another surface and get G0-G3 continuity? Also, is there a "query edit" equivalent, so you can actually look at what affects the history of a surface and make changes to it?

[@SimplyRhino3D]

In Rhino you can match to a trimmed surface. The edge of the surface that is changed by the matching needs to be untrimmed. Does that make it more clear? The terminology or meaning of ‘Project’ is different in Rhino. If you would like to take a surface and apply it to another surface then you should look at Orient on Surface. If, for example, you used two surfaces that had the mathematical criteria to be G3 continuous, one surface being smaller than the other, then you could orient the small surface onto the larger surface then trim the larger surface with the boundary of the smaller surface. You could achieve G3 continuity across the edges in this scenario.

[@eobet]

That's really interesting! Thank you for the information. What happens if any of the CVs of the larger surface moves? Does the smaller "oriented" surface move with it? And does the trimmed edge also update?

[@SimplyRhino3D]

Orient on Surface is History enabled in Rhino, so you could change the large surface and the smaller one would update. Once you trim the large surface though, the trimmed edge will not adjust exactly in-line with the small surface. As an intermediate step one would use Intersection Curve (which does move with History) and then trim when you have reached your final stage. The best way for you to check this out is to download a trial version of Rhino from www.rhino3d.com

Thanks for the additional information. I've waited 8 years for Rhino to catch up to Alias, so I can wait a few more. ;) Surely some day Rhino will have history enabled on all its functions, as Alias does?

[@M3LKS]

Hi and thank you for these insights into Rhino 6. Are there any notable improvements in Rhino 6 in terms of surface continuity - I specifically mean when modelling more complex objects using bezier patches and requiring G2 continuity in more than only 2 sides of the patch. I know it is doable in Rhino 5, but it is very time consuming.

[@SimplyRhino3D]

Hi MM3. In short the surfacing toolset is broadly the same in v5 and v6. However the History implementation does make a real-life difference to the ability to maintain G2 continuity across a number of edges.
