Finally, with vertex snapping, #Bézier curves in Blender are a breeze to use, so I switched back to my original method (since 2015) for building #SubD model. It gives me nice, even patches and full control over the density. #b3d
Sooner or later I will be able to do it, for now it seems that something is improving, I managed to create an #IGES file exported directly by #Blender, and also a #STEP file always with the same #Python add-on. #b3d #CAD #SubD #nurbs
I've asked to #AI, an add-on to export #SubD to #NURBS from #b3d, the add-on managed to export something to both IGES and STEP, there are no errors, the exported files contain data structures but unfortunately any #CAD app managed to open those, although that seem like a failure, it's not, in fact it is the first time that I get an add-on that exports both in #IGES and in #STEP directly from #Blender without using external library, maybe next time I could be able to have a working add-on.
I'm not happy with this, but it was an overrated application, as well as being very expensive, for what it offered, with exceptional marketing behind it, important contacts in the #VFX industry that allowed it to take advantage of an undeserved advantage, in some videos they mocked other applications, but in the end, they decided to stop development, a shame for those who believed in this project. #modo #Foundry #2D #mesh #SubD #b3d #Blender #Blender3D
#CAD model vs #SubD, with a little slight difference on bevel radius #Plasticity3d #Blender3D. #b3d
Just for fun, I've redone it with #SubD and quad topology with edge loops, in #Blender3D, total time 15 minutes. #b3d #Blender

These days I was thinking about subdivision surfaces, which were invented by Ed Catmull to allow greater freedom than #NUBRS in animation, but they have become a tool used everywhere allowing greater freedom, however a concept that has never evolved. I loved the "bicubic patches" applications. #SubD #CAD

The #SubD conversion of #FreeShip into #IGES is still unmatched for me, is an old Pascal code that works perfectly, very light file with surfaces with the same topology of the mesh cages #nurbs #CAD #plasticity3D #Moi3D #b3d #Blender3D #fc3d #opensource

From Blender Subdivision To N.U.R.B.S. (IGES) for free

Hi all, I have a little trick that I discovered just today and wanted to share it with you. I found an easy way to convert the subdivision surfaces, in to nurbs surfaces. To do this you need two free programs ’ FreeShip_Plus ’ and another to convert VRML format ’ 1 ’ First you need to export your files from Blender, eliminating the subdivision modifier and export to obj with the Z axis at the top, after using the program “meshconv” to convert from obj to wrl. Open ’ FreeShip ’ and import the...
