Hi there how do you unroll a surface of let's say a 3D scanned arm? I have reduced mesh, contoured it, and network surfaced it to rebuild it. My end goal is to project a 3D extruded design that wraps around the arm, I've tried flow along srf but it just doesn't come out as expected. how would you advise me to approach this?
instead of using smash use CreateUVCrv* and 1-ApplyCrv command if you don't care about history update or 2-use PlanarSrf on the result of CreateUVCrv to make base surface and then use FlowAlongSrf. *smash command gives you those distorted boundaries but CreateUVCrv make perfect rectangle that is easy to work with. 28:28 in this case follow this path: explode polysurface then use MergeSrf one by one to make a one piece surface from parts, and the use CreateUVCrv and then 1-or2- 👆🏻
For sure, thanks for your suggestion! The video was intended for 2nd-year students first learning some of the curve/surface functions in Rhino, so it is a bit "quick and dirty" and not precise. Maybe I'll try your method and make a video about it sometime!
It really depends on your curves and the geometry. You can try rebuilding both surfaces to a higher isocurve density to ensure that it can handle all the splitting required. Otherwise if the problem persists, you can try extruding the curves a little bit in both directions, and using the extruded surfaces as the splitting geometry.
i have a proplem with Rhino when i want to mesure the Distance between tow Points in Bloc, i can´t select the corner without selecting the Bloc could you helb me to get out Please
Stuart Hearn that really just depends on how you draw it, since that is not the topic of this video meant for beginners I don't get into that. Regarding Rhino or any other CAD program, they have all slowly evolved but the principles of geometry and using tools intelligently hasn't changed. Nor has the issue of user error and uninformed opinions.
Stuart Hearn it is, however you can judge for yourself since it tells you how much it distorts. For some more flexible materials or lower tolerance constructs that may be just fine.
Thank you so much! The way you explain this was so detailed and helpful. I will definitely look at all your other tutorials.

one of the best rhino tutorials out there. thx man
Thanks forthe all educative information buddy It helped me alot. .👍🏻
thank you very much for this tutorial. very useful and clear!
Nice ! I use them to made one crown. Thank you for the tutorial.
This tutorial is good. Good content on your channel!
That was awesome...thank you very much!
Amazing! Thanks for sharing!
Amazing stuff...
Thank you so much it is really really helpful!!
THANK YOU SO MUCH. THUMB UP!
Very useful, thanks!
Thanks for making the video
Liked a lot !
many thanks !
Amazed
awesome!
Damn !!! Thank you so much you save my project !!!
Glad it helped!
great tutorial thanks a lot!!

Thanks for the amazing video! I was wondering is there a way to make complex loft curves have a thickness?
NS Studio do you mean to pipe the curves? Or to give a complex loft surface thickness?
@@LeeSuHuangdoes it make it 3% bigger or smaller…?
@@canmandan6 You can run the area calculation to see. It will depend on the geometry.

so it is easier to draw it by hand, using offsets from contours
muy bueno
Great Tutorial! how did you make the pattern piece that you used to flow along the surface?
The Voronoi component in the Grasshopper plugin for Rhino, with a pretty even random point distribution.
Hi, thank you for nice tutorial. How did you prepared that voronoi structure?
Voronoi 2D component in Grasshopper.
Gracias
how did u made that height reference line ??? please explain
when you analyze area it is miles out when smashed
tfw it's ribbed for her pleasure
Hey I need the Pattern Structure File Please!
hi, after flowalongsrf i am unable to split the surface,please help

Try turning on different options in your object snap options, it should allow you to snap to vertex when in distance measure mode.
@@LeeSuHuang thank u bro you are the best
I can't unroll the surface cuz the curvature is from two direction
Yup, that's to prevent excessive distortion. Smash may get you some part of the way but be aware there is going to be inaccuracies.
im following every step but it doesn´t work, why the hell it works with you and not with me ?
It's hard for me to say without seeing what exactly is wrong.
you taj=ke a cube, fillet say 500 radious, cant even flatten that
N
it will not even small simple compound , so rhino has gone nowhere in years

No disagree
I can send you a file just a simple 500 radious corner
Areas wrong lengths smashed wrong
smash is rubbish really, rhinodraws but is rubbish to flatten compound
