I converted an old model I had made with #gCAD3D over to #SurfacePsycho. I think there's nothing better than Surface Psycho for designing #hulls. I tried remaking it with Moi3D and other #CAD programs like Plasticity and FreeCAD, and the only two that really satisfied me were gCAD3D and SP. but SP is much better than gCAD3D for this task, you have total control.
All the other add an unnecessary amount of CVs, while Moi3D is the only one that actually causes deformations. #opensource

Out of all the free programs for NURBS modeling that I've tried, there are only two that are harder to use than #SurfacePsycho: #Ayam and #gCAD3D. Ayam is limited when it comes to exporting, but it has a ton of tools; gCAD3D, on the other hand, is seriously powerful, it's lightweight, and to model with it you have to use APT a sort of G-code.#CAD #opensource

My daily CADs are #Plasticity3D, #Moi3d, #FreeCAD #gCAD3D and #Blender3D, for 2D I use #QCAD, I don't use any more Windows since years, #Linux

#gCAD3D saved me many times, is a small application that open #DXFs the older versions, but save files into #IGES or #STEP and permit me to works with plans of others, sometime is hard to opens file from other but in somewhat this small application heal those messy #CADs, it is only 1.7mb, it opens also STEP or IGES but isn't always the best way, but many times is the only way.

The power of #gCAD3D, if you know how to use it, here's a hull I made when trying to learn this very powerful little program, the surfaces are done by manual input via #APT #CNC code, a simple language. #opensource #CAD #hull #rowing #boat

My tiny #gCAD3D has recently been updated to version 2.60, very useful when others fail in certain operations I do, it has some defects, but it is powerful if used in the correct way with many functions and installed it occupies only 1.8MB ;)
For #Ubuntu #Deb or #RPM is needed this dependencies "libgtkgl2.0-1" to make it working, is under rewrite of some part but works with it until the update of# #IGES of the export code. #CAD #linux #OpenSource

Sometimes I try them all but in the end even if #gCAD3D has its flaws it remains the only one that manages to export #STEP or #IGES files that can be opened by #Plasticity, I'm talking about #DXF drawings, I have to do so many of these steps it's incredible that #Moi3D, #FreeCAD or Cad Assistant all fail and a 1.3mb program does the job just fine.

People underestimate #gCAD3D, but it's very powerful and very small, a bit difficult to use, the best way is to use it via code, and it's not difficult, but it's also a great tool to do some small conversions from #Blender to #CAD, save into IGES or STEP, many times it handles CAD #DXF files very well and better than FreeCAD. #b3d

Here is a comparison between #gCAD3D, an application just over 1000kb, which imports a file correctly against #ZW3D 2023 which is really bad.🤨 #CAD

Here is a quick demonstration of a hull created directly in #Plasticity from curves which I however made in #gCAD3D with APT CNC code.
This application is simple to use and to learn especially those who know how to use #Blender will have no problems. #CAD #NURBS
