Nurbs curves is a good tool for clean and accurate curves, I can't understand why the most blender's teachers ignore this important tool for industrial design.
Because you can just create a flat plane and work with it . Maybe not as accurate but almost the same result with and not much complex
Because there r better CAD softwares out there than blender
@@nightblade178 but the CAD software don't have sculpting, painting, other artistic tools, animation and node editing, I don't think...
The fact that blender incorporated NURBS is proof of how well built the program architecture truly is
@@GuiPurri that's because it's CAD. U don't sculpt while engineering. Everything has to be precise down to the last millimeter.
@@nightblade178 not everyone’s an engineer and surely Blender is mostly used for animation and 3d presentation work
I have been using blender for years and I still feel like I’m an absolute beginner. Thanks!
So do I sometimes. Keeps it fun!
Wow, please show more of the car-modeling techniques please with these nurbes
It's on my to-do list!
I second this
@@BlenderSecrets plsplsplsplspls
@@BlenderSecrets there are many wanting to learn nurbes in blender including myself
@@autodriver3617 Yeah, there's just not that much to Nurbs in Blender I think. If you're really serious about Nurbs maybe look at Moi3D, it looks pretty interesting - moi3d.com/ You can work with that and bring it back into Blender to add details and render.
I always struggle when dealing with smooth curvy meshes where i have to tweak each of the vertices to get those smoothness that i want.. how i wish I found this video earlier.. thanks mate!!
This looks like it could make modelling clothes and armors much easier
I have a problem, I did exactly the same, but when I pressed F to fill the Nurbs becomes cyclic, it doesn't create faces (3.2)
In case you never figured it out, you chose the nurbs curve from the curve add menu and not the surface menu.
For all the people asking why they can’t make a surface when they press F. Watch carefully, I go to the Surface > Nurbs Curve instead of Curve > Nurbs Curve. I made a new video about it to make it more clear. ruclips.net/video/3OfShkLcj-c/видео.html
Thank you so much.
I didn't even know you could do this with curves? Mind blown, this will be so useful. Thank you.
Awesome- I had discounted Blender NURBS curves for a long time because of the hairy look. This looks MUCH cleaner and like a CAD NURBS curve
Oh, I didn't really use it much either but it's actually not bad!
@@BlenderSecrets The video is stunning understanding that Blender's NURBS is ignored and hated, did you made that in one piece?
Viewport Overlays - Normals (uncheck)
Itz the exact stuff that i was searching for 5 days. I mean a perfect method to make a car fender.Thank you a lot .
This is exactly what I needed! I've been trying to model a complex spaceship with a lot of curved surfaces and its really hard to do it with proportional editing. Im definitely going to try this! Thanks!
Good luck!
LOVE this tutorial. Right to the point and shows you the basics. Perfect!!
You are nothing but god of blender😮👍🏻
This was very very useful thanks
Awesome, very amazing - the most technical part in blender is smooth meshes
Best blender tut ever
Thanks :-
Yes! This is the way to do tutorials! Thank you!
Thanks!
Whoa never seen this type of modeling this is really cool
AMZING! thank you so much!!
Every video is really good learning tool!
The e-books also
Thank you David!
That would have saved me so much time.
congratulations, you have invented subdivision surface modeling
wow! new ways just opened up for me .. nice video keep it up man
I have been using bezeir curves before, this looks so much easier thank you
Exactly what I was looking for. Tvvm
Oh yes exactly what I want, the CV curves. Only one thing left: curve comb plot and g1, g2, g3 continuity options;)
Wow, it giving us perfect topology
Thank you so much for this! I was looking for a video but I didn't know what this technique was called, and it really helped me with one of my projects.
Holy moses, thanks man for this video
Blender is an overpowered tool in this industry.
It can certainly do a lot of stuff!
Wow, I've yet to explore the nurbs functionality in Blender. This video has got me going there. Thank you.
Not sure if there's much more to explore, sadly.
@@BlenderSecrets If you find it later. Please keep uploading. I think there would be tons of people are waiting for it.
Yeah! I want shorts to be flooded with this kind of educational videos. Though I think that youtube doesn't recommend such videos over the crappy ones.
Thank you so much 💕😊😊
Before this is very difficult for me now I can make
Your videos are incredible, thank you ♥️
Thanx for sharing !!!
Would love to see a car tutorial! Would love to model a DB5 in Blender
Thank you, this was really useful! Thanks!
고맙습니다
Hmmm ... Armor ... Just what I needed.
this channel deserve more subscribes 👌🌹
simply awesome.
Good video
This helped my Mountain road so much! Can you teach us how to make, Initial D Fifth stage textures? If you can?
Great stuffs and thanks for the video. Unfortunately, the NURBS in Blender cannot be exported as a NURBS format such as STEP or IGES. Otherwise, there is a possibility of it being used for creating parts for mass manufacturing.
TIL Nurbs are a thing...and they're pretty handy!
Yeah, they're not so well-known but actually pretty good!
NURBS are cool
I agree!
You got new subscriber! 👍😁
Amazing
amazing like always
Wow. This is cool.
Nice
cool
Wow that video was really helpful
When I press F I got the message "too few selections to merge" I have 2.80, All the points are selected. I tried to subdivide the nurb curves but it doesn't work too.
I figured it out. The two curves must be joined as one object, and you can only fill two rows at a time and they need to have the same numbers of segment points.
Yeah you should definitely duplicate the Nurbs curve in Edit Mode, not in Object Mode.
So what's the difference between this and subdivision surface? The interpolation method? Its still just polygons
why is it that it wont fill after i duplicate the curve?
instead it will connect the duplicate curve
You are using a curve, not a Surface... When you press Shift+A, you need to select Surface, then Nurb.
@@Guilherme-social Thanks for the answer
I have used curves and surface modelling extensively in maya for things like cars which need nice curved surfaces. Now since i am trying to get into blender.. i am searching for tutorials that help me achieve a similar workflow ... this short tutorial helped... also if u are aware of something called rebuild curve in maya, how can i do that in blender?
Hey, glad it helped! I haven’t used Maya for over a decade and even then it was only for like a week, so I don’t remember it that well. What would the rebuild curve tool do?
@@BlenderSecrets Rebuild curve re-distrbutes the control vertices (hulls) on the curve. Similar to the Loop Tools -> Space for polygonal vertices.
If someone occur problem - add curve from surface section, not from curve section!
Man !!! Thanks a lot, i dont see the differenc in Curve - Nurbs curve and Surface - Nurbs curve - but you make it clear.
What is the difference between it and subdivision surface?
Oh wait you can actually do that where have I been
In blender 3.22 the command F just connect side points, there is no fill effect as on video. I duplicate curve in edit mode, so they are joined as one object. I try several time back and force - the same result, maybe it is now working in another way? I decide to test in 2.8 - also dont work. I select both curves in edit mode and pressing F just connect opposite side of curves and make like knot curve, no filling.
After that i starrt reading comments and found my mistake - i dont saw the difference in "Curve - Nurbs curve" and "Surface - Nurbs curve" These are different ones. Now it is clear for me.
Cool!
When I press F, the face is not created but two vertices get linked
muito útil.
Why said "too few selections to merge when I try to fill ?
Can anyone explain why nurbs curves are made with endpoints deactivated???
Didnt even know Blender had nurbs capability. Can poly mesh be converted to nurbs surfaces? Can nurbs surfaces be exported for use in Rhino?
When I press F, it's closing the curve instead of making it a surface. What's wrong?
Can anyone please share the full tutorial for car 🚘 or anything else modeling using nurbs
I have one question, Is it possible to make the object more thick?
When I press F only two vertices get connected, why is it not filling the whole thing?
Many people put tutorials on RUclips but don't show what keys they use.
Now if blender had something like T-Splines
Can you explain what T-splines are for?
@@BlenderSecrets So T-Sp;lines was a plugin for Rhino, basically it used nurbs surfaces in the same way you would box model, extruding faces, creasing edges, you could also extrude nurbs curves lathe them and so on, just how you would build a model from say a cube or a profile curve you could do the same in T-Splines, it was a plugin that i literally fell in love with, beautiful to use and the output was stunning to look at, sadly its now been acquired by auto desk and resides in Fusion 360.
Blender's Subdivision tools is just like T-splines. However, Blender's tools including its NURBS toolset cannot export real NURBS such as STEP or IGES formats. As such, it is not possible to be used for parts design for mass manufacturing that requires mold tooling. BTW, rhino 7 will have its own Sub-D toolset as demonstrated here ruclips.net/video/Naw_bMLDEPU/видео.html :)
@@simpernchong you can import a subdivision 0 mesh into Fusion and convert it to T spline, or Convert that into a Brep, and it looks identical to how it does in blender.
What function is this F hotkey?
My preset value of Blnder shows that F HotKey is "Make Segment",
So I cannot use F to create a surface.
F is for Fill, just like with normal mesh geometry. You are probably using a Bezier curve, and not Nurbs.
@@BlenderSecrets
I checked the Scens Collection and I'm sure that NurbsCurve was created.
@@BlenderSecrets ruclips.net/video/wXzDbS3BT34/видео.html
Sorry, I think I'm stupid. The correct way is to use Surface-> NurbsCurve so that I can do it correctly.
@@BiseChen That's odd, I can only tell you that F is the default for Fill in Blender. Are you in Edit Mode, is everything selected?
why i can't use F to fill curves, in Blender version 3.4.1, it just joins two curves
Nice tutorial, but it doesn't work for me. When hitting 'F' the two curves just connect with an additional segment. Where is my mistake?
Need to use Surface->NURBS Curve, not Curve->NURBS Curve
can we boolean nurbs??
mhhh dumb question: what's the difference or benefit of using this instead of just a regular mesh with subdiv and stuff?
Im adding nurbs curve, mark checkbox to see the ends if the curve. Than duplicate curve the same way as shown in video in edit mode. Than press A to select all points in both curves and than press f. And it not works. Only end points connecting, but not the whole curves. Maybe you know why this happening ?
As comment bellow by
Nj Njhjh pointed out you need to use Surface->NURBS Curve, not Curve->NURBS Curve.
Whats the background music?
Great
I can't fill with F. It just connects lower left and upper right vertex points instead of filling it like in video. And yes i selected everything as said
You're using the wrong Nurbs type. Follow the steps again and look at the menu I get the Nurbs from. I literally just made a new Nurbs video because I get this question every day lol... oh well
@BlenderSecrets I have rewatched it 20 times and haven't seen it till now. And i was confused that icon in menu on the left is different. Now i remember that i have seen in some other video, can't find it now, that it is important to use nurbs curve from SURFACE, not from CURVES.... Sorry for bothering you and thanks for fast response. Most toutubers never reply to comments.
@@DIABULUSKIRA I even made a new video which is very clear so people don’t make this mistake - ruclips.net/video/3OfShkLcj-c/видео.html
What's the difference between this and regular subserf modeling?
You can set point weights with NURBs, there is more fine control. Subdiv is easier to work with in some cases, but you can also destroy your topology easier.
@@SoftBreadSoft thanks
Fun Fact : Most 3d Studios In The Past Uses This
I can Not do it on macbook, if i press "F" its just connect two edge points, what can i do?
Hello, thank you for your explanations, but when I do the manipulation you told me, it just gives me black lines in the shape of a segment and not a filling. How should I do it ? Thank you
this doesn't work for some reason i hit F and nothing, im on nurbs???
Show bro the keys you use. I am a beginner and want to learn more. I admit I don't have them with English. I use a translator for English.
oh my god！
Is there any video which demonstrates how to model a car with NURBs detail????
Not that I could find, sadly
For me, F did not fill it with faces - it just added a new segment between the original and the clone.
What am I doing wrong?
I made a curve, hit Shift-D, then G, Z, moved it up, then A to select all, then F.
Probably you didn't choose Nurbs surfaces
@@BlenderSecrets Thanks, you were right. It's a bit confusing that Blender has NURBS curves under both Curves and Surfaces, but only Surface curves can be used to create surfaces.
What's the difference/advantages to subsurf modeling?
Exactly what I'm wondering
it has to be specific surface type?
👍👍👍
what is it used for?
just a car?
can this facility replace rhinoceros up to a point (moderate)
is this not basically the same as using a subdivision surface modifier?
So this begs the question: if I can build NURBS Surfaces in Blender, why can't I import NURBS Surfaces and render them as surfaces, and not mesh?
And that's basically all there is for NURBS in Blender, especially when compared to any other NURBS-based modeler. I wish that I was very very wrong. How can we convince Blender Foundation to develop NURBS?...
Unfortunately I couldn't find much either. I don't know if it's got to do with "convincing" Blender Foundation, as they don't have unlimited funds and have to pick their battles. The more support they have financially, the more likely it is to see the things you want in it :-) You can always support them with monthly donations.
@@BlenderSecrets Thank you for the answer, I totally agree with you. On several occasions I proposed to establish a fund for NURBS specifically. As I understand they thought about it but haven't decided. I'm open to donations, but I'm afraid they'll go into some character creation or animation related area, which is wonderful for those who need it.
Plus, I heard Pablo Vazquez saying that developers could take on an idea if it is presented to them in a convincing manner. But I reckon it should be a community effort. For me there's no doubt, if Blender excels in NURBS it will open itself to Industrial Design and Architecture. Big industries, a lot of studios. They need NURBS.
@xg223 It depends on the industry. In animation and character creation indeed there's no much need for the Nurbs. But in architecture and design, that is in the industries aimed for real life objects production, the Nurbs are quite a must.
@xg223 as said NURBS are extremely handy when you need precision, like NURBS are in a way "vectors" for 3D modellers, as vectors are in Illustrator. You would not draft floor plan in Photoshop via pixels, but take vectors in AutoCAD/Illustrator... going into 3D, if you model e.g. sphere with mesh-based geometry, PC doesn't "see" sphere but a bunch of polygons... on the other hand NURBS based 3D geo is accurate, like a sphere is a real sphere and ist shape is computed with guide curves, points, which can be mathematically written in code... the best application of this advantage is then e.g. with 3D programming used to build generative algorithms, such as for generative art or parametric modelling. Like bringing full Grasshopper into Blender would be madness. I know Blender got Sverchok but I think it is lacking a lot, because of GH user base.
