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

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

I've just dropped two #propellers done with #SubD in #Blender and converted into #IGES and then to other #CAD formats.
The models in low poly can be used with SubD modifier and they are also UV-mapped too. Useful for your #boats model in every place from #b3d to CADs. #Blender3D #boat #design

However my skill matters because I've tested the same workflow also with #Blender, and the result is convincing. #b3d #propeller #boat #ship #CAD #SubD #Blender3D

#ExportIGES #Addon updated to v 1.5.5 for #Blender v 4.0 Limit surface shape along soft creases now correctly coincides with the shape in Blender. #b3d #Blender3D #CAD #SubD to Nurbs as #IGES

I am so happy with the result and I also have to share the rear of the stern with the #propellers mounted, before I used models already made or I made them schematic or with #SubD. This is the best I've modeled in #CAD, from now on things are simple. I get it how model a blade with airfoil, next step make one from a real 2D drawing.
I've seen some tutorials on YouTube and those are really bad. #ship #boat #design

A workflow that works with all OS.
From #Blender3D to Plasticity via converting #SubD to Curve then into #Beziér and decimating with adaptive and exporting into #SVG with #LeoMoon Add-on and importing SVG into #FreeCAD and exporting into IGES or STEP and then import into Plasticity, however you can use this workflow your with preferred application.

Greetings.

After many trials for me there isn't better way to convert a #Blender's #SubD to #Nurbs #IGES. 
Using #FreeShip and #meshconv, that is the method to have perfect surfaces based on the initial topology that allows you to have total control over the final result. #b3d #blender3d

After #IGES export and #Rhinoceros export, Digital sculptor have update the #Alias Export add-on for #Blender, these three exporter give you the possibility to export your file to those #Nurbs applications by converting the #SubD's cage into Nurbs Surfaces. unfortunately I don't have Alias. but for who has this application can help. #b3d #Blender3d #CAD
