For reference, this is what I’m talking about:
Also, note to admins: do you think we should add some kind of category for CAD applications and questions?

I think we could add one. Consider it done.

@SirGeekALot, there are other environments that use a patching paradigm but they are more geared towards audio/video like Max/MSP or PureData (open source) Some of these support 3d files but it’s more rendering than editing. Apparently there are some attempts to create something similar to Grasshopper for Blender:

Please, check this
Anandamide looks potentially interesting, but it’s been over 5 years since there was an update, and 7 since any meaningful activity — not seeing a release, and compiling might be complicated since it references QTCreator 5.6+.
There are some other developments along these lines since:
- Blender, in addition to Sverchok has a native node programming system (added since the above posts were made over a year ago)
- Ryven https://ryven.org/ has gained support for PythonOCC: GitHub - Tanneguydv/Pythonocc-nodes-for-Ryven: Pythonocc nodes for Ryven
- there was an effort to put pyFlow into FreeCAD: node editor - pyflow - FreeCAD Forum — but it’s since stalled
- there is puredata (usually used for audio) in FreeCAD: Graphical scripting : FreeCAD/PureData connection - FreeCAD Forum
- GitHub - kovacsv/VisualScriptCAD: A simple visual scripting based 3D modeling application.
- there was FloodEditor, but the site seems to be off-line: https://www.reddit.com/r/cad/comments/bdvcnt/parametric_cad_system_under_mit_license/
there are a couple of others, but those are the highlights.
As noted at:
I’ve been using BlockSCAD, exporting to OpenSCAD/RapCAD, and working from there — if you can use an STL, you can use BlockSCAD directly.

To add to the Blender point, this is a constraint based geometry sketcher for it:
And this is a repo of extra Blender addons for CAD:
Both seem well regarded, and the first seems to be getting a lot of active development.

A new development in this space is:
which exposes all of OpenSCAD.

News here: There’s a new fork of pyqt-node-editor, under development, that might be interesting here.
