With that in mind, I started modelling the neck, which I expected to be the most complictated part (Narrator: It definitely was.) First, the trivial (i.e. flat) bit, which are the headstock and the heel - both can be modelled as extruded outlines.
In contrast, the transition between the main neck profile and the heel was a bit more intricate. It is basically a loft group from the rectangular heel profile to the final rounded neck profile with an intermediate half-rounded step for good measure, but it took me a while to get right due to weird random geometry artifacts introduced by the #OpenCascade loft implementation. Tweaking the shape and the group settings helped a bit after all.
OCCT 8.0 (aka Open Cascade Technology) is out! It's the CAD kernel used by many projects such as @freecad, #CadQuery , #build123d or even @kicad ! It has wrappers for STEP and IGES and can use BRep topology representation. A very important open source tool for the hardware world!
We regret to inform our community that the fundraising campaign to purchase the AutoCAD (*.dxf) format was not successful. Despite the announcement, only 15€ were received. As a result, we will not be acquiring the OpenCascade plugin at this time.
Finally, please note that we do not sell or reuse your data like most companies. If you want to benefit from a great service, please consider making a small donation.
We're thrilled to share the first prototype of our custom CAD binary format (GBKF1000), designed to reduce file sizes by up to 80% and improve loading times in our WebGL viewer.
Also, As part of our commitment to open source, we're also releasing parts of the project as free software:
GBKF Core specification: https://gbkf.rsm92.fr
C++ library: https://github.com/rsm-gh/gbkf-core-cpp
Python library: https://github.com/rsm-gh/gbkf-core-python
My talk at #FOSDEM was accepted for the Open Hardware & #CAD/CAM Devroom! "PostCAD: #OpenCASCADE in the #Database"

@ericbuijs Hey Eric, I made a quick visit to the FreeCAD forum, somebody posted about this new open source 3D CAD program. I thought you’d be interested.
It’s based on the Open Cascade kernel, uses the SolveSpace solver, can do fillets and chamfers, and import/export to STEP.
Still basic features, and no packaged build for Linux (yet?), must be compiled… No Mac version.
There’s a flatpak! https://flathub.org/apps/org.dune3d.dune3d
