Understanding Curvature and CV Massaging

[@darkooo94]

This is probably the most informative, knowledge packed surfacing video on KZbin. Finally someone explains the idea behind class A and shows the real methods of high level control over the quality of surfaces. This is some real pro stuff

[@dimitrispappas2411]

You know exactly what curvature is and that is obvious. I have seen many tutorials about it, but you are the only one that explained it perfectly. After watching this tutorial I understood it very well. I anticipate more tutorials from you. Thanks for sharing your knowledge.

Thank you for your efforts! Its really hard to get access to this knowledge outside of professional cad design studios. I think I would be able to solve a surface layout like this but I really struggle with more complex blends when four surfaces meet. I sometimes spent hours without even reaching g2 continuity... let alone g3 on all four sides. Its like running in circles! If you ever find time, i´d love to hear if there is some sort of structured approach on how to align complex transitions and/or use analysation tools of alias to read the surfaces. Thanks!

Hello SIr, your videos are helping me a lot to understand surface modeling. Please continue doing this great job !! much love from italy

[@frankyphix]

Really enjoying your tutorials. Even though I don't do car design, it's still useful and interesting seeing CAD concepts like this being discussed.

[@7evensabre]

Thank you for this amazing Tutorial Ray. I know that we have gone over these tools a lot in our tutorials, so I have been using them quite familiarly recently!

[@HISEROD]

Holy crap! You said at the end "I know it was a super long one..." and I thought "what?" I can't believe I didn't realize that I had watched an hour of CV massaging lol.

[@Gichanasa]

Very nice to see someone covering high level surfacing. Also impressed with using Grasshopper to prepare the lecture notes... flexing much?

You always been a good teacher and I admire you Thank you sir

[@rubens181]

As always great tutorial Ray. I did really enjoy this one.

[@wei-paihuang3648]

Awesome stuff as always. Thanks for the dedication to making these new videos, going as far as writing an algorithm to illustrate continuity. Bravo!

I was Told to never build from trimmed edges, is that true? If so what is the best practice to build something is I need to trim the surface that I created to build a complex surface?

[@HandleBar3D]

I think what they were saying is never use the edge of a trimmed surface as the input to build something. Which is probably because when you do that you are building off a curve on surface which is usually heavier. What I do is if I want to build off a trimmed surface edge, I’ll rebuild that trimmed edge using curve rebuild or curve duplicate (kinda the same tool) and make sure it rebuilds a cleaner curve, then use that as my input to build anything off of. Another method I use is just trim converting the surface if it’s 4 sided and now those edges or clean and no longer trimmed, but that depends heavily on having and ideal squares trim. You can technically skip all these steps and just make sure whatever tool you are using is set so that when it builds the surface it builds them with the desired degrees and/or spans. So technically you could build off a trimmed edge but you’ll have a more controlled result rebuilding the edge using the tools mentioned above.

Amazing

[@ryanleung4556]

At 39:43 what is the difference between moving the outside arrow and the inside one. It seems these arrows can move the CV in the same direction, so why do we need 2 arrows?

[@HandleBar3D]

It follows the tangent line of either side. It does seem like the same direction because they are similar angle but they are different lines. If both sides were exactly the same following a straight path then yes both arrows would technically do the same thing. But most of the times their will be differences and following the right tangent is important concept to understand.

[@jonasthegreat6508]

I've just started learning surface modeling using rhino but it's kinda difficult for me to make smooth surface transition of a car body. What's your opinion about rhino3D for car modeling, have you tried using it?

[@HandleBar3D]

I don’t think it’s ready just yet, but I do believe they are coming out with more surfacing related workflows

[@jonasthegreat6508]

@@HandleBar3D I hope so. So sad autodesk killed VSR but yeah thanks a lot man. Learned a lot from your videos.

[@Cenario3dbrasil]

VSR enabled Rhino to compete with Alias in the past. That's why Autodesk moved swiftly and killed VSR.
