Thanks for this intro video, Phil! And THANK YOU, Robert McNeel & Associates, for bringing Sub-D workflow back to Rhino after AutoDesk took it away with T-splines. I can finally retire my Rhino 5.0 because I won't need to use my old copy of T-splines anymore! This is a game-changer!
Awesome video Phil! Glad to see that the “snatch and grab” of TSplines prompted the internal development effort of a SubD utility for the folks at Mcneel. Moreover, I truly appreciate your breakdown of NURBS, mesh, and SubD object topologies!

Hi, To select SubD Edges either use Sub Object Selection (Shift+Control on PC or Shift+Command on Mac) and pick the edge or edges you need. Alternatively use the ‘Edge’ selection filter from the SubD toolbar - to add more than one edge hold down Shift. Hope that helps!
Stitch creates an edge while Fill Hole creates a lack of an edge. However, if one does not want the edge to be hard (ie filleted) that's when you use Crease, or in this case, remove crease. SingleSubDFace uses edges to create a new face. (Use the flat view.)
Hi Yusra7. This video was created with a WIP version of Rhino 7. At that time the SubD Loft was a ‘Style’ Option in the usual Loft Dialog Box (along with Loose, Tight, Uniform etc). In the shipping version of Rhino 7 there is a dedicated ‘Loft’ command in the SubD Menu and the type in commands are now different ‘_Loft’ and ‘SubDLoft’. Hope this helps.
Thank you very much for sharing this. It was a great way of explaining the difference between Nurbs, poly surfaces and SubD's and I've picked up some great tips to improve my modeling skills.
Hi Frederick. Where the control points sit relative to the knot lines will depend (amongst other things) on the degree of the surface. On a Degree 1 surface if you add knots and visualise the control points they will be on the knot line intersections. On a Degree 3 surface (as on the video) the points may not lie on the knot line intersections. Hope this helps.
If you read Autodesk’s entry on Wikipedia, they are cited as having damaged / delayed the introduction of global illumination to the world when they purchased Lightscape and subsequently shelved it.
@Orengo Roy Here on Wikipedia is the list of Autodesk discontinued software - en.wikipedia.org/wiki/Autodesk#Discontinued_products - killing off many good pieces of software to manipulate the market. And here is what is said about Autodesk regarding Lightscape; "Lightscape 3.2 Was the world's only radiosity rendering package at the time (1991) developed from work done by Donald Greenberg at the Cornell University Department of Computer Graphics. The problem with this part of Autodesk's history is that it was a time of discovery in computer graphics, and Cornell was one of the birthplaces for the technology. In this sense Lightscape was more than just another product, it was an essential part of the development of rendering technology generally, and part of its evolution. Additionally the software came from a university research department and represented the start of a development cycle that users the world over were watching closely. Regardless, Autodesk purchased rights to the software and promptly discontinued its sale. A primitive version of the radiosity renderer was incorporated into the companies 3d Studio Max product, while existing Lightscape customers and the product were simply dropped." Autodesk are bad, greedy, evil. I did have a copy of Lightscape back in the late 90's and I'm a relatively new user of Rhino (3DS Max for 20 years) - I really love Rhino, it's 'my kind of software'. Love it to bits (though I am a very light user, I intend to use it a lot more).
Hi Comprime. To select a single SubD face you can use either the selection filter in v7 and set this to faces (this is in SubD tools) or use Sub Object Selection (in Windows hold down Shift+Control before clicking on a face or edge or on a Mac it’s Command+Shift). Hope this helps.

Hi Neville, Probably both, but having a solid understanding of NURBS topology will really help you with creating controlled surfaces that are not overly complex.
Hi Phil! Why would you rebuild the Sub-D iteration in just NURBS for the final version? What are the drawback of subd compared to nurbs only ? I'm coming from a industrial design background. So technically I could 3D-print a subd to nurbs conversion or are there any difficulties?
Hi Alex, Thanks for watching and your question. The SubD object is one continuous surface and some operations can only be done in NURBS. You’d need to convert to NURBS to do things such as: Split, Trim, Boolean Operations, add Fillets with known radii etc. You’ll need a Tri-Mesh for STL output but yes you are correct in assuming you can go SubD-NURBS-Mesh. Cheers, Phil
Hi Phil, I have just downloaded Rhino 7 eveluation and I have noticed that when I click on a curve the control points automatically come on, is there any way of changing that so they only come on when I turn them on. I have rhino 5 and this doesn't happen on there, I find this very annoying. Need help.

Great video! An aside, how did you produce the 'triangular' portion with NURBS commands at 10:20? SplitEdge & BlendSrf for the other parts clear enough, but it gets tricky at the end with 3 edges. Thanks
Hi, Could you please respond to those questions: 1. Is a Rhino sub-d surface a NURBS surface by its nature? 2. Can NURBS and sub-d surfaces be connected seamlessly in Rhino? 3. Can such functions, as booleans, be applied to sub-d surfaces inside of Rhino? 4. Can we import mesh surfaces from another programs, and use them as sub-d surfaces, and convert to NURBS?
Hi Mike, sure: #1 - Rhino SubD surfaces are a distinct object type. The Limit surface is Spline based. #2 - If you mean can a SubD surface be joined to a NURBS surface then the answer is no. SubD Surfaces and NURBS surfaces are different entities. You would have to convert the SubD surface to NURBS before joining the result to other NURBS surfaces. #3 - If you use Boolean Difference, for example, to remove a NURBS cylinder from a SubD ‘sphere’ then you will achieve a result but this result will be a Polysurface. Likewise if you Boolean Difference two SubD objects the result will be a Polysurface. #4 - Yes. You may want to look at simplifying and re-topologising complex imported meshes with QuadRemesh before converting to SubD Hope that helps.

Hi Edward. Do you mean the reflective surfaces (for example seen on the ‘Y’ branch at 10 mins)? If so this is a customised display mode - I started with a copy of the Shaded Mode and then used a ‘Custom material for all objects’. This material is a fairly glossy white with a reflective environment applied. The environment is a blurred version of a commercially available external HDR that I converted to JPG and blurred in Photoshop.

Great tutorial! However, I seem to be missing something when using Loft on SubD Friendly curves, as I'm not given the option to create a SubD loft. Any ideas why? (video around 21:30)
Update: So it seems to me Loft in the live r7 version got a brother in SubDLoft, which executes a loft with its own options window when used, as opposed to the one used when performing a regular Loft. Hm.
Hi iEscap1sm. In the production version of Rhino v7 the SubD Surface commands are in the SubD menu, rather than as shown in the video. Hope this helps.
@@iESCAP1SM Hi, thanks for putting forward the question! I found the exact same problem while trying, and this Q&A really helps. Also appreciate the answer from Phil. Thank you both again. ;)
Fillet makes arc (2nd degree circular) blend surfaces. Adjusting a SubD (which is 3rd degree) to fit end points of an arc, results in much more weighted fillet (sharper corner) and is not circular. Approximation is the best choice by extracting the arcs and trying to mach them as close as possible withthe smooth visual representation of the SubD mode. That is how I do it at least.
The final bit at minute 36 is a bit unsettling to me. I have been working recently on a project where I need to make in SubD two planes that intersect doing a quarter pipe, i.e. 90 degrees perfectly rounded quarter of a circle. The problem is that with SubD the shape starts to change before the circle should start, modifying the straight part. So here, the presenter says at min 36 that the SubD shape is pretty close (actually better he says) than the NURBS, but the truth is that it is different and maybe you want to do it the same while having SubD edits capability. Is there a way to achieve that? Note: I have tried with _bridge command, but the same thing happens.
Hi Miguel. You cannot achieve a constant radius (arc based) fillet with SubD. SubD is roughly analogous to Degree 3 NURBS in that it produces freeform geometry - so in this case you’ll have a constantly variable radius surface.
Hi Lucky Strike. Yes you can Edit the Blend Edge here as you suggest and this works quite well. I wanted, however, to show a SubD alternative. The advantage with SubD here is that you can Add/Remove/Slide Edges to control the shape and effectively move the Setback too - with Edit BlendEdge you cannot move the ‘corner’ Setback.
This is awesome! I'm loving rh7. The multipipe is great. Dumb Question... How do you close a multipipe? I'm using the GH component and unless I have another curve(s) joining at that end it maintains open. Anyway to cap it with a round cap? Thanks in advance
Hi Carlos. Glad you are enjoying Multipipe - when you are using this in Rhino there is a command line Option ‘Cap Ends’ which can be toggled on or off. If you want to close the ends after using Multipipe then use Fill with the Single Face Option. In both cases you’ll need to add a Crease to the ends after creating them. Hope this helps.
Hi Evandro, Yes, but personally I would use SubD for the conceptual design, to explore and develop forms. Ideally you would need Rhino’s NURBS surfaces for hull forms and superstructure so that you can maintain the correct fair-ness and clarity of form. SubD could also be extremely useful for interiors for areas such as upholstery and fabrics where we are dealing with less structured forms. Hope this helps. Thanks, Phil.
Hi, Not easily, so we would suggest keeping the SubD geometry on a separate layer instead of deleting when you convert to a poly surface. Right now you can convert a single surface to a SubD but not a polysurface. So, if you have a polysurface that needs to be a SubD then use QuadRemesh as an interim step then with the SubD option On. Hope that helps.
Hi Phil, thanks for the video as always. I learned something with the MeshFromLInes, didn't know that one. Also, I have a suggestion regarding SubD topology. In your y-branch example you end up with triangles in the transition. Triangles and NGons are pretty bad if the goal is a smooth surface. Y-Branch topology can be modeled using all quads. there's one solution with 2 6-edge poles, or the "standard" solution which is 4 5-edge poles. While poles aren't perfect either, they usually yield better results than triangles or NGons. If you post your email address I can send you a .3dm with both examples. Love your videos and there's so much new stuff to learn with the addition of SubD to Rhino. Cheers.
Hi Mark, Thank you for your positive comments. There are certainly many ways to model the ‘Y’ branch and it would be great to see your solution. You can use the e-mail address from our website : info@simplyrhino.co.uk Thanks again, Phil.
Always the best clarity Phil. Thanks for this one too. New to subD. Process strategy for joining 6 tubes at a common center with each out plane with the others? (Multipipe not useable.)
Hi Mel, I would concentrate on the topology and let the shape sort itself out to begin with - retain a four sided topology wherever you can. Main requirement would be that each of your six ‘tubes’ had the same number of faces/edges around the circumference. Then you can use ‘Bridge’ or to create transitions between single pairs of faces/edges at a time, gradually working out the topology as you go. You might find that ‘Append Face’ is useful too in manually creating single faces as will working in ‘Boxy’ (ControlNet) display rather than using the smoothed form. If 1-2-1 training would help then we do offer that as a service too, just let us know and we can send you more details.
@@SimplyRhino3D Thanks for this Phil - I will follow the process you have described above. Please send additional on training. My Rhino Discourse ID is mhristau if that’s a better channel.
Very nice, Thanks Phil! SubD modelling is fast and more easer. I hope Mcneel will not kill traditional nurbs tools ))) I heve a suggestion about SubD mesh. It is very necessary to smooth the surface against curvatures and bumps of the surface for a smooth design. You can make a mesh relaxation tool. It will smooth out the vertices and tangency of patches on the border evenly.
There are no plans to ‘kill’ the existing NURBS tools. Rhino SubD objects are not mesh based. They are splined based, therefore there is no mesh to smooth. If you consider the topology carefully and aim to create good, predominantly quad based topology you can achieve a smooth transition to NURBS
Yeah. That really is a game changer, isn't it? All of the things which we loved about T-Splines (and got frustrated with in Clayoo) are now standard with Rhino 7...
Hi, I created a custom Display Mode for this. I duplicated ‘Shaded’ as the starting point and used Custom Material as default. This has a Gloss Intensity and Gloss Finish of around 90%-95% and an environment which is a blurry HDR reflection. Hope this helps.
New to Rhino (was using Fusion360) Thank you for an insight into NURBS SubD etc. I have to say though it would be easier for the likes of me if it was a bit more plain speak and less Open University tech speak.... None the less at least I know there's stuff in Rhino that I may be able to get a grasp on now as I was close to giving up. It's really difficult to find any Tutorials for beginners especially up to date. It may be that I've just happened to come in just as V7 has been released but I can assure you that there's a lot of similar Fusion360 Refugees looking for replacement software that they can trust right now. I'm not alone. I'm also using FreeCAD now which is similarly impressive software, likewise Blender.
Thank you for the feedback Kelvin, we do understand your point on “plain speak” it’s a challenge though to adopt this in all cases as quite often when discussing these subjects the only accurate description or term is one which can have a mathematical basis and so can be difficult to describe in any other way, but we take your point on board and will consider this as we progress with new videos. Very interested in what you say about Fusion 360 users or refugees, why do you think that is happening? Finally please come along to our December 2020 Rhino 7 event where you’ll see all the latest versions of the tools plus a Q&A with the developers www.rhino3d.co.uk/events/rhino-uk-user-group-meeting-december-2020/
Excellent teaching skills and useful information. This could be the fastest, shortest, and easiest way of teaching. However, I still did not find the SubD fully competing with the T-spline due to the angular symmetry option only. If there is a way to simulate angular symmetry in the SubD then I can take back my word :)
Hi Serkan, There is no angular symmetry as yet in SubD for Rhino (that’s true), we would not be surprised to see those features come in a future v7 Service Release (or perhaps v8) though.
Control shift grab an edge face or vertex drag with and then release control and shift to extrude SubD geometry. Much easier than building curves etc. as done at 30:50
Have you tried exporting the SubD model to 3ds Max, or similar software? I'm hoping the quad-based geometry will be retained for easy UV-ing and even sculpting in ZBrush.
Hi, Sorry but we do not have access to 3ds Max, if you do have access and wanted to perform some tests please contact us directly through our website & we’ll send you the files to test import.
Hi Anthony. Your SubD surface will need to be meshed for 3D printing output. So, briefly starting with a Closed SubD, use Mesh, Triangulate Meshes and Export the Mesh as an STL file.
Hi, thanks for your kind comment, glad you found the video useful. We have online Grasshopper training courses that I would recommend, these start with our Grasshopper Level 1 (7-week) - you can found out more and book this course via this link: simplyrhino.co.uk/training/courses/grasshopper-level-1 Hope that is useful?

Nice tools. Still waiting for DIRECT EDITING capabilities a la Moi3D and Sketchup. The Direct Editing It will be very useful for a lot of architectural and quick designing works.
If you mean simple ‘Push-Pull’ editing of solid faces and edges then look at the ‘Solid Editing’ tools or ‘Sub Object Selection’ with the Gumball manipulator
Many thanks for the (as usual) superb tutorial ! It can also be that StarPoints do not apply in the Rhino SubD surfaces, but if they do, can you tell me if the Rhino SubD surfaces also have a continuity limitation of G1 at those points like TSplines ? Cheers
Hi Joao, This topic is addressed within a discussion on the Rhino 7 SubD support forum, hope it helps: discourse.mcneel.com/t/subd-vs-t-spline-geometrical-differences/77876
There is no set timetable for the release of Rhino 7, like previous releases we will all see the final release announced once the new features, like these SubD tools, are settled and performing well. Bear in mind though that all users of Rhino 6 can access the WIP (Work In Progress) version of Rhino 7 and use / test these tools as they develop.
min 15 high points - you have those because you split an edge into a triangle - triangles for subd modeling are not good. you should have collapsed all those faces into a line and maintain quad faces
Hi Claas. Thanks for your comment. Agreed, four sided faces are optimal for SubD, particularly when being used to convert to NURBS, but I wanted to show that this is not a limitation.

At 28:04 the symmetry tool (like in T-spline) would be really useful. I hope that would be included in the final release.
That's partially implemented with the reflect command. V7 is a WIP and is updated weekly at the moment.
Yes, Reflect is a partial solution but this could become history enabled to give something similar to TS History.

Excellent, you can just use Tab to toggle between box and smooth display (no need to make a dedicated button).
It is strange that my control point on surface is not like 5:14. The control point is on the cross of the knot
Hi Frederick. Where the control points sit relative to the knot lines will depend (amongst other things) on the degree of the surface. On a Degree 1 surface if you add knots and visualise the control points they will be on the knot line intersections. On a Degree 3 surface (as on the video) the points may not lie on the knot line intersections. Hope this helps.

The problem is that with SubD the shape starts to change before the circle should start, modifying the straight part.
So here, the presenter says at min 36 that the SubD shape is pretty close (actually better he says) than the NURBS, but the truth is that it is different and maybe you want to do it the same while having SubD edits capability.
Is there a way to achieve that?
Note: I have tried with _bridge command, but the same thing happens.
Hi Miguel. You cannot achieve a constant radius (arc based) fillet with SubD. SubD is roughly analogous to Degree 3 NURBS in that it produces freeform geometry - so in this case you’ll have a constantly variable radius surface.
Great video and excellent narration!!! Thanks for sharing Phil
Wasn't the "Edit blendedge" enough for the example u gave at the end of the video ?
Hi Lucky Strike. Yes you can Edit the Blend Edge here as you suggest and this works quite well. I wanted, however, to show a SubD alternative. The advantage with SubD here is that you can Add/Remove/Slide Edges to control the shape and effectively move the Setback too - with Edit BlendEdge you cannot move the ‘corner’ Setback.
cant believe how many hours I spent getting this right back then in rhino 6
Hi, i have one question, why i can't see the black edge line in any of my subd plane or objects?
Hi, I would start by opening the Display Panel and making sure that ‘SubD Boundaries’ is checked. Does this help?
At 24:18 can someone remind Tesla to turn the toggle back off?
Superb. Excellent overview. Thanks
This is awesome! I'm loving rh7. The multipipe is great. Dumb Question... How do you close a multipipe? I'm using the GH component and unless I have another curve(s) joining at that end it maintains open. Anyway to cap it with a round cap?
Thanks in advance
Hi Carlos. Glad you are enjoying Multipipe - when you are using this in Rhino there is a command line Option ‘Cap Ends’ which can be toggled on or off. If you want to close the ends after using Multipipe then use Fill with the Single Face Option. In both cases you’ll need to add a Crease to the ends after creating them. Hope this helps.
Excellent, clear and engaging. Thank you.
Thanks, Larry
thanks for the explanation in a moderate speed
Would Sub-D be the most suitable tool for designing a yacht?
Hi Evandro, Yes, but personally I would use SubD for the conceptual design, to explore and develop forms. Ideally you would need Rhino’s NURBS surfaces for hull forms and superstructure so that you can maintain the correct fair-ness and clarity of form. SubD could also be extremely useful for interiors for areas such as upholstery and fabrics where we are dealing with less structured forms. Hope this helps. Thanks, Phil.
@@SimplyRhino3D thank you so much!
@@evandromarchezinibezerra5206 You're welcome!
Any way to model symmetrically, as in Blender's sculpting mode?
Hi Parker. You can use the ‘Reflect’ command to adjust one half of a shape and have the other half update automatically. Hope this helps.
@@SimplyRhino3D That's perfect! Thanks so much.
Thank you. Can you convert the solid back to subD?
Hi, Not easily, so we would suggest keeping the SubD geometry on a separate layer instead of deleting when you convert to a poly surface. Right now you can convert a single surface to a SubD but not a polysurface. So, if you have a polysurface that needs to be a SubD then use QuadRemesh as an interim step then with the SubD option On. Hope that helps.
Hi Phil, thanks for the video as always. I learned something with the MeshFromLInes, didn't know that one. Also, I have a suggestion regarding SubD topology. In your y-branch example you end up with triangles in the transition. Triangles and NGons are pretty bad if the goal is a smooth surface. Y-Branch topology can be modeled using all quads. there's one solution with 2 6-edge poles, or the "standard" solution which is 4 5-edge poles. While poles aren't perfect either, they usually yield better results than triangles or NGons. If you post your email address I can send you a .3dm with both examples. Love your videos and there's so much new stuff to learn with the addition of SubD to Rhino. Cheers.
Hi Mark, Thank you for your positive comments. There are certainly many ways to model the ‘Y’ branch and it would be great to see your solution. You can use the e-mail address from our website : info@simplyrhino.co.uk Thanks again, Phil.
@@SimplyRhino3D Thanks for the response, I just sent you a .3dm with both topologies.
really good video and purchased the rhino license
how do i make my emap "texture" looks like yours?
Hi Andrea, its a Custom Viewport Mode not an Map - and the setup is explained towards the end of this video: ua-cam.com/video/YyC5DffMl3c/v-deo.html
Always the best clarity Phil. Thanks for this one too. New to subD. Process strategy for joining 6 tubes at a common center with each out plane with the others? (Multipipe not useable.)
Hi Mel, I would concentrate on the topology and let the shape sort itself out to begin with - retain a four sided topology wherever you can. Main requirement would be that each of your six ‘tubes’ had the same number of faces/edges around the circumference. Then you can use ‘Bridge’ or to create transitions between single pairs of faces/edges at a time, gradually working out the topology as you go. You might find that ‘Append Face’ is useful too in manually creating single faces as will working in ‘Boxy’ (ControlNet) display rather than using the smoothed form.
If 1-2-1 training would help then we do offer that as a service too, just let us know and we can send you more details.
@@SimplyRhino3D Thanks for this Phil - I will follow the process you have described above. Please send additional on training. My Rhino Discourse ID is mhristau if that’s a better channel.
LOVE RHINO 7!! GREAT JOB
amazing
cant wait the release
Very nice, Thanks Phil! SubD modelling is fast and more easer. I hope Mcneel will not kill traditional nurbs tools )))
I heve a suggestion about SubD mesh. It is very necessary to smooth the surface against curvatures and bumps of the surface for a smooth design.
You can make a mesh relaxation tool. It will smooth out the vertices and tangency of patches on the border evenly.
There are no plans to ‘kill’ the existing NURBS tools. Rhino SubD objects are not mesh based. They are splined based, therefore there is no mesh to smooth. If you consider the topology carefully and aim to create good, predominantly quad based topology you can achieve a smooth transition to NURBS
amazing, similar to t-splines, grat job rhino
Great introduction and an excellent explanation! Thanks!
Yeah. That really is a game changer, isn't it?
All of the things which we loved about T-Splines (and got frustrated with in Clayoo) are now standard with Rhino 7...
Thanks a lot.I wonder how can I make my environment map like yours.
Hi, I created a custom Display Mode for this. I duplicated ‘Shaded’ as the starting point and used Custom Material as default. This has a Gloss Intensity and Gloss Finish of around 90%-95% and an environment which is a blurry HDR reflection. Hope this helps.
@@SimplyRhino3D that's super cool. I didn't know I could create custom mixes of Display Modes (like having colored objects while in Arctic mode).
New to Rhino (was using Fusion360) Thank you for an insight into NURBS SubD etc. I have to say though it would be easier for the likes of me if it was a bit more plain speak and less Open University tech speak.... None the less at least I know there's stuff in Rhino that I may be able to get a grasp on now as I was close to giving up.
It's really difficult to find any Tutorials for beginners especially up to date. It may be that I've just happened to come in just as V7 has been released but I can assure you that there's a lot of similar Fusion360 Refugees looking for replacement software that they can trust right now. I'm not alone. I'm also using FreeCAD now which is similarly impressive software, likewise Blender.
Thank you for the feedback Kelvin, we do understand your point on “plain speak” it’s a challenge though to adopt this in all cases as quite often when discussing these subjects the only accurate description or term is one which can have a mathematical basis and so can be difficult to describe in any other way, but we take your point on board and will consider this as we progress with new videos.
Very interested in what you say about Fusion 360 users or refugees, why do you think that is happening?
Finally please come along to our December 2020 Rhino 7 event where you’ll see all the latest versions of the tools plus a Q&A with the developers www.rhino3d.co.uk/events/rhino-uk-user-group-meeting-december-2020/
Excellent teaching skills and useful information. This could be the fastest, shortest, and easiest way of teaching. However, I still did not find the SubD fully competing with the T-spline due to the angular symmetry option only. If there is a way to simulate angular symmetry in the SubD then I can take back my word :)
Hi Serkan, There is no angular symmetry as yet in SubD for Rhino (that’s true), we would not be surprised to see those features come in a future v7 Service Release (or perhaps v8) though.
Control shift grab an edge face or vertex drag with and then release control and shift to extrude SubD geometry. Much easier than building curves etc. as done at 30:50
Have you tried exporting the SubD model to 3ds Max, or similar software? I'm hoping the quad-based geometry will be retained for easy UV-ing and even sculpting in ZBrush.
And if you have, how did the creased / non-creased edges transfer over?
Hi, Sorry but we do not have access to 3ds Max, if you do have access and wanted to perform some tests please contact us directly through our website & we’ll send you the files to test import.
i need to find some time to use WIP7 thanks for the tutorial,
You're welcome Richard, hope you enjoy the QuadRemesh video we've just posted too - and find some time to try out the v7 WIP.
nice clear voice sound.
Amazing explanations! I'm new to Rhino and this video really helps. Many thanks! ;)
Great, hope you enjoy your Rhino time!
Hey Phil, how do I prepare a SubD surface for 3D printing?
Hi Anthony. Your SubD surface will need to be meshed for 3D printing output. So, briefly starting with a Closed SubD, use Mesh, Triangulate Meshes and Export the Mesh as an STL file.
@@SimplyRhino3D thank you Phil.
thank you so much Phil for this lovely lesson , do you know of a really good grasshopper course??
Hi, thanks for your kind comment, glad you found the video useful. We have online Grasshopper training courses that I would recommend, these start with our Grasshopper Level 1 (7-week) - you can found out more and book this course via this link: simplyrhino.co.uk/training/courses/grasshopper-level-1 Hope that is useful? Let us know if we can help further or give you any other information.
Nice tools. Still waiting for DIRECT EDITING capabilities a la Moi3D and Sketchup. The Direct Editing It will be very useful for a lot of architectural and quick designing works.
If you mean simple ‘Push-Pull’ editing of solid faces and edges then look at the ‘Solid Editing’ tools or ‘Sub Object Selection’ with the Gumball manipulator
This is awesome!
No more Going back and forth to Rhino 5 just to use T Splines.
Obrigado por compartilhar seu conhecimento.
You're welcome, thanks for watching.
Hi, I cannot find the Bridge command in Rhino 6. is it available only in v7 ?
Many thanks for the (as usual) superb tutorial !
It can also be that StarPoints do not apply in the Rhino SubD surfaces, but if they do, can you tell me if the Rhino SubD surfaces also have a continuity limitation of G1 at those points like TSplines ?
Cheers

Looks like a new paradigm. Basically NURBS stays NURBS, just borrowing the polygonal modeling workflow. Clever.

Now we have to wait 5 years for rhino 7 to be released 😛
Nurbs combined with SubD with high degree of accurancy....jesus, thats nuts
What's SubDay.?
wonderful thank you
amazing! thanks a lot
Awesome...... Where v7 will be out to upgrade?
There is no set timetable for the release of Rhino 7, like previous releases we will all see the final release announced once the new features, like these SubD tools, are settled and performing well. Bear in mind though that all users of Rhino 6 can access the WIP (Work In Progress) version of Rhino 7 and use / test these tools as they develop.

VERY NOICE!!!
min 15 high points - you have those because you split an edge into a triangle - triangles for subd modeling are not good. you should have collapsed all those faces into a line and maintain quad faces
Hi Claas. Thanks for your comment. Agreed, four sided faces are optimal for SubD, particularly when being used to convert to NURBS, but I wanted to show that this is not a limitation.
good!!
good news ) i like it
