If I didn't want to be precise could I just add that blend using two points that I insert rather than the sphere or use a projected arc ora circle to speed things up?
I'm teaching myself and already have found using some of the basic ideas presented to be time saving and - fun - I have encountered a situation where I need to do the opposite of a trimmed corner - instead o increasing the number of curves from three to four I feel I need to reduce the number of curves from five to four. Joining various pairs 'sort-of ' works but if you provide a suggestion or two i'm happy to put in time and effort without turning it into a protracted discussion. Thanks for the series though I'm nowhere near understanding some of the later chapters.
Awesome, thank you! I thought I was already proficient to some degree (haha pun) in Rhino, but you show me I’m not yet there 😄 I really like your examples, they’re easy to follow, especially when there’s a little bit of prior knowledge. Also learnt the term "rats nest of curves"! ^^
I was clapping and laughing when you showed the trick of how to avoid the 3 corner surface. up until now, I've watched all the episodes because you explained the basics and logic of good surfacing so well, So it was a very good review. from this episode I really feel I'm learning new stuff that I was looking for, for a long time. Thank you!!
Dude, you are a godsend. I've been struggling with trying to make my files clean and editable. I usually resort to just scrapping and remaking the whole model again when complex edits are required. This has changed my entire approach to surface modeling in rhino, can't thank you enough!
Thank you so much for these videos. I´ve been working with Rhino for years and doing all the mistakes that you list. Your videos have really opend my eyes to a lot new ways to do things in Rhino. So thanks again for taking time to do these excellent videos.
Great videos, I have been trying this trick for a while but cannot seem to get past an issue. Most of my transoms are not vertical, I think this may be the problem. When I finish my surfaces, they are not single span, they come out with another set of isocurves at the top of the sphere blend. I am then also unable to matchsrf. Any suggestions ?
@@thirtysixverts thank you for the reply, it says that it is a polysurface. I cannot send a screenshot of the surfaces on this youtube comment section.
@@CJColl So, something is going wrong with how you are generating that surface - what command are you using to make it? You can only MatchSrf with surfaces, not polysurfaces.
Originally I would’ve used so many loft and sweeps for sure to get the same result you did in just so few surfaces thanks for this! You’re amazing my dude thank you.
It really sucks that Autodesk bought VSR and then tossed it in the bin. They really screw independent designers with their greed. I used to use Alias, but it's too expensive as a sole proprietor. So here I am learning yet another bit of software just to do a few surfaces. Better late never, but I still have my custom Alias interface burned into my brain, so I'm struggling learning everything over again. Glad I have some resources to help at least.
Why 3 sided srf is not good? Is there any explanation? And also Im not sure why you always use split edge to ensure it is a closed polyline before running edgesrf because rhino can handle with it, maybe there's difference between r5 and r7? Very great video, really appreciate that
Could you do an example on a simple planning boat with chime and spray rails + thickening it? Making it thicker is what I always struggle when trying to 3D print the hulls I need too, also, my co workers need the hulls with the thickness for solidworks assemble + interference check.
@@thirtysixverts I subscribe to such an idea. I know Rhino is all about surfaces, but even so, hull thickening would be so helpful, even in non-production designs! Basic offset is never going to work well, especially in rabbet or forefoot areas! Anyway, this was a great tutorial, but kind of gave me white hairs in understanding what is wrong with singularities and that trimmed corner thingy. Thanks!
I got it, but I had to use refine edge to get the 4 sided surface to join the little trim. Not sure what I did wrong. The pulled curve used to split it had tons of points, maybe something wrong there.
Or I can go from .001mm Absoluto tolerance to .002 and it will match. Humm, ill keep working through the material, come back when I understand more. Thanks man, this material is gold. Sincerely, thank you.
@@ThePhilbox It could simply be the size of what you're making, relative to the file tolerance! If you're using 0.001 mm as tolerance but making stuff actually the size of a boat hull, having to use Refine is not at all surprising. Scale matters when it comes to tolerance!
@@thirtysixverts Yes! I wasn't building to scale. That is it exactly. Thanks again! I'm learning a ton. Watching each video at least twice. Lots of little info nuggets tucked in there.
@@ThePhilbox Yeah definitely scale and tolerance matters for things like this! Even so, sometimes you can end up needing more control points to go watertight. In those cases I use ChangeDegree and bump up the degree on the edge that needs more points.
This is eye-opening!! Thank you very much for your explanation, this is a Gem rhino tutorial. I have been suffering a lot from these 3 edged surfaces. Hope you can do more advanced rhino tutorial! And an early happy new year!
I will definitely be doing more advanced project based tutorials in the future, just been fully booked the past few months with a very intense automotive project!
@@thirtysixverts btw sorry could you explain how did you manage to make that bow curve @ 2:40? or you made the whole bottom curve at once before? Do you have the work flow of how you move the start of the bow curve? thank you!
Sky, this is really cool stuff with brilliant problem solving. I am a guitar maker, new to surfacing, played with Fusion 360, now trying out Rhino 7, and have gotten this far in the series without being totally overwhelmed (just 80% lol). I want to model an archtop guitar top to carve on CNC machine and would really like to hear your approach ( number surfaces, how to get watertight, etc), using NURBS, or is SubD a better choice. Thanks! --carl
Hi, when ı "matchsrf" on one edge the other edges are broken down. Then I run "matchsrf" again on the broken edge it breaks the edge that was just fixed. What is the problem? By the way, it's a great tutorial.
Okay, this maybe a dumb question, but I’ve been using rhino for few years now and this is the first time I learn about these things, that’s why I still don’t get why the hustle. However, I understand the importance of having clean surfaces as it affects the final form. So simply, Is this important for architectural design and I have to understand the best practice or it’s more about product design?
Definitely not a dumb question! For sure this stuff is way more geared to product design - really anything where CAM/CNC will be the primary mfg process and surface quality matters.
I did have a question regarding matchsrf. I don't know if you explained this in the next videos but more often than not it says trimmed surfaces can't be matched why does it work in this case where you're splitting it with that pulled edge?
Trimmed edges are a necessary part of modeling - unless your model is dirt simple, there's just no way to get around them. That being said - when you make nice smooth primary surfaces, what you'll often find is that you get much much better matching to that trimmed edge. You will still be matching to tolerance instead of EXACTLY, but life is full of tradeoffs, and sometimes you just gotta take matching to tolerance!
My match Srf between the little rounded surface and the bow srf doesn't make it watertight .. I recheck and recheck every steps and i don't get it, did someone encountered the same ?
Very interresting..you teach Rhino in a very professional way..Thank you. But you should specify that your workflow is that of Class A modeling and it doesn't concern all users of Rhino.
Saying Class A is fighting words on the internet lol! You'll notice I do everything I can to avoid the term, because I think it creates a totally unnecessary conversation. Certainly the approach I teach can lead one to models that would qualify as Class A, but I also firmly believe that anyone who cares about making a quality surface model can benefit from having a good knowledge of patch layout, surface matching and point editing. IMHO - it really and truly helps to understand why Class A modelers structure their models like they do. Even if you are not going for that level of quality, the mental toolkit that you can develop with that approach is incredibly useful to even the average modeler.
Question: at 12:01, the pull command creates a curve that is not single span, right? When I MatchSrf at 12:30 (with the same settings), my positional tolerance is 0.006, kinda high... Is this normal? Is this a problem?
Any trim curve created by pull (or project, or really ANY method) will create an edge that is not single span, and often with uneven point distribution. If I have a surface like yours, that is CLOSE to my file tolerance (0.001 in this case) but not hitting it, I would use ChangeDegree and up the degree across that edge, and re-run MatchSrf. Repeat as necessary until you hit watertight. Alternately - sometimes things just don't want to join, for reasons that aren't clear - in this case I untrim my surface and then Pull my existing surface edge as my trim object. That will reset the trim closer to the shape of the surface you already have.
@@thirtysixverts Upping the degree did the trick this time. Thanks for the reply. And thank you for the series! I'm only a few weeks into using Rhino so not really the target audience you described, but I'm still learning a lot from your videos. You're telling us WHY to do things a certain way. That's what's often lacking in the tutorials I come across. Greatly appreciated!
Hi... why my curvature graph didnt show the hair like yours? (minute:33) It just a tiny hair come out from my line. does it have any setting could you advise sir?
Well that, and the fact that I can count on one finger the number of improvements for surface modeling from V5 to V7, so it's not like I'm missing much from a pure surfacing standpoint.
@@thirtysixverts Sad to see vsr tech in alias and fusion 360 and not in rhino. Are we ever going to see it in rhino? Looks like v8 is out of question...
