I'm trying to learn from self-taught #Nurbs Class A quality modeling, and it is not easy, one thinks he has understood all the secrets #3D modeling and then you find yourself fighting against bulges and surfaces that do not align..🥵 #b3d #Blender3D #CAD #SurfacePsycho #design

Exercise with #SurfacePsycho. a simple model created with various techniques and tools inside #Blender the model is made with #Nurbs and it is exportable to CADs as #STEP or #IGES. #b3d #Blender3d #CGI #CAD

It was hard to get a solid from all these surfaces, the biggest problem is symmetry and mirror modifiers, but you always learn something new in the challenges. #b3d #Blender3d #Blender #CAD #Nurbs #SurfacePsycho #Toyta #logo #3D

Hey folks, today I found out there are actually other CAD-type experiments using Blender's geometry nodes. Here's another geometry nodes approach for modeling NURBS surfaces in Blender; the author is Mathias Schulenberg. #b3d #blender3d #CAD #nurbs

You probably won't believe me, but with #SurfacePsycho you have individual control over every element, from curves to #NURBS patches, and you can change the degree of the patches or curves. You can also create patches freely, but you can constrain them to curves. I mean, I don't know if I'm making myself clear, but it's both parametric and freeform. And it's just the beginning; there's still a lot missing, but there's already plenty, and it's been built with a clear vision. #CAD #b3d #Blender3d

Hey psychos, it’s not easy, but bit by bit I’m learning to do manual alignments with G2 continuity, using that specific node for the checks. I gotta say, it’s not simple to figure out how to do it, it’s a real challenge, but at least I don’t have to fight with the deformations you get from the automatic ones, which can sometimes be more of a headache than a help.
Two separate surfaces, but decent quality even if they’re done by hand. #b3d #SurfacePsycho #CAD #nurbs #Blender3d #Blender

Small progress, but with considerable effort. some parts I have to redo.

I tried again. No way! Surface Psycho is much better.. here again with dedicated command of xNurbs "square with g2 on target surface.. And with SP I can have also continuity up to G4, is another universe.😅 #SurfacePsycho #nurbs #plasticity3d
on the left Plastcity3D, and on the right Surface Psycho.. :badabing:

Maybe I'm not great with Plasticity and Class A modeling, but at the bottom left the continuity error from Surface Psycho is acceptable (marked in green), while the one from xNurbs on the same NURBS patch, where I used the "Square" command (xNurbs' dedicated command for Class A patches), has a bigger error, highlighted in yellow, and it's really obvious. Surface Psycho 1, Plasticity 0.

In my rush to build a model with surface patches on the laser scan, I completely forgot that you can trim surfaces, which is essential. I tried it out on the rear door and side windows of this Mercedes, but I think I’ll need to trim surfaces in other spots too.
I proceed slowly, because I am making so many attempts and tests on how to make surfaces. #SurfacePsycho #CAD #b3d #Blender #nurbs #Blender3D

This is an old exercise from the Autodesk Alias docs.
I’d already tried it back when I started making my first models with Surface Psycho, but I couldn’t get anywhere.
Today I gave it another shot and pulled it off.
Now I think I could even manage to add the fillets and make it almost a Class A model, these are all primary surfaces.
With Surface Psycho it’s all about the order you do things; first you do some stuff, then you do the rest. #CAD #nurbs #Blender3d #SurfacePsycho #b3d

The more variable I add in order to control patches, the more complicated it gets... just trying to get tangency between surfaces with a nice control cage is a nightmare, and I don’t even want to talk about G2 continuity, that’s basically hell... But at least I’ve learned to tweak every part of the surface, from a single vertex to the final result. Maybe one day I’ll pick up a new trick or two... #surfacePsycho #b3d #blender3d #CAD #nurbs

Hi, in the video you can see how to control patch shapes using the loft section curves. As you can see, by adjusting the tension you can selectively tweak the profiles, and that then changes the loft patch. This way, by modulating the tension of individual rows of the control cage, I can get patches with varying tension instead of them all being the same. It’s just an idea to show how is the surfaces control with #SurfacePsycho. Cheers. #b3d #blender3d #CAD #nurbs

This image, it seems something trivial, but in reality it is a Nubrs model, with a higher quality than those I have done in the past, this model in fact has regular Nurbs patches, with pretty nice continuity G2/G3, But I'm still learning. #b3d #Blender3d #blender #nurbs #CAD #classA #SurfacePsycho

Tips on using Surface Psycho's "Crop or Extend Patch" and SP’s Rise or "Lower Degree Bezier Patch", then I made instances with Alt+D now the copies share the same set of CVs. Making instances is really handy.
Now, as you can see in the video, splitting the big surface into three parts gives me a more even and better distribution of CVs, while I still have control over all three patches that can be tweaked with the loft curves. #b3d #surfacepsycho #CAD #Blender3D #nurbs #engineering

But with the latest version of #FreeCAD, I can no longer import the curves that are inside IGES and STEP. Is there another way to do it now? #fc3d #CAD #nurbs

Hey psychos I made a short video, originally it was 20 minutes long, so it’s a bit fast.
I hope you don’t freak out watching it.
In it you’ll see how to reverse #engineer using #Blender and Surface Psycho; I walk through my workflow for creating #NURBS Bezier patches and curves.
I’ll try to make a longer tutorial later with better quality, for everyone else.

Bye, psychos 😅 #CAD #b3d #SurfacePsycho

Ok, I'm back to making models with Surface Psycho. It's been a while since I did anything in #Blender. Anyway, after a lot of testing and experimenting, for now I've decided to do the G1 and G2 continuity alignments between NURBS patches manually, without all the parameters, I find that works better for me. #SurfacePsycho #CAD #boat #design #freecad #b3d #hull #ship #Blender3d

Is like that, the making of Class A surfaces with G3 continuity #Nurbs #CAD #Surface

It's not bad to have a native #Blender add-on like Surface Psycho that lets you create #NURBS models and also convert SubD models into #STEP files to open in #FreeCAD and other #CAD software. The SubD models aren't perfect, but with a bit of work you can get great results. ATTENTION, do not use too complex models with SudD😅 ☠️ #SurfacePsycho #b3d #Blender3D

Concept modern #Ship With #Blender and #SurfacePsycho #b3d #Blender3d #CAD #Nurbs #design #hull

I tried making a SubD model and then converted it to NURBS using Surface Psycho's geometry nodes. In just a few minutes of work, like 20 minutes, it's not perfect; you know it takes hours to make a really good quality model, but I'm impressed. Since the control cages are meshes, you've got all of Blender's options, and you can manage the final topology. #b3d #Blender #Blender3d #nurbs #CAD #SurfacePsycho
