OCCT VS FreeCAD

So have I have this project of writing a geometric kernel, something in the vibes of Opencascade : https://dev.opencascade.org/

What is this opencascade open source cad. The only thing I find is freeware (not open source) stuff at https://dev.opencascade.org

They integrated OCCT, so they do now have code to read STEP as part of the code base. Yes, I am aware it is tessellated right now (which is the obvious first step to make it work), but that can be changed in future. Point is: they now have at least half of the necessary code available.

The only thing coming to mind is https://dev.opencascade.org/ - it was the original kernel of the ipad app shapr3d.

The OpenSource cad project, are you talking about this? https://dev.opencascade.org

nvm, here's this:

Also, FreeCAD is built on the OCCT library and it inherits many of its limitations from that. Ideally, a lot of issues should be fixed in the library and FreeCAD would automatically be improved. Unfortunately, and I could be wrong, but I don't think FreeCAD developers have much influence on what happens at OCCT, apart from filing bug reports and such.

Nice! I'd add FreeCAD, and also the RealThunder fork https://github.com/realthunder/FreeCAD which adds enhancement(seems to be getting slowly merged to mainline).

Lithium Titanate batteries. Nothing else is lightweight, safe, currently available, and lasts 20000 cycles.

ESPHome. It's a framework for declaratively building firmware for microcontrollers, based on rules like "This pin is an input with debouncing, when it changes, toggle this".

Contributing to them has probably been the most fun I've had programming in years.

We just need power management, and a C++ implementation of the Native API client. It's so close to being able to replace most of what I'd normally code by hand in Arduino.

RealThunder's fork of FreeCAD: https://github.com/realthunder/FreeCAD

They fix so many issues. Linear patterns can duplicate other linear patterns!

Vorta: It's the best backup technology I've seen. Just an easy guided GUI for Borg, which gives you deduplication. I just wish they let you deduplicate across multiple repositories somehow.

JFTR, FCStd-files produced by RealThunder's LinkStage[0] (fork of FreeCAD) is not fully backward compatible with an official FreeCAD app, and wise versa.

So, if you are planning to use LinkStage app for some large project, be ready to use only one app for the whole project and be ready to lost in whole or in part compatibility with the users of an official FreeCAD.

edge is where all the exciting new features got released. It contains the latest commit from the FreeCAD Link Branch (https://github.com/realthunder/FreeCAD). Unlike the convention, here, the user is encouraged to try the edge release, to help improve all new features so that they can one day land in upstream FreeCAD.

I downloaded this latest version 2023.01.31 from Github but i have no idea how to install it and if it is the right version that will work with Midnigh GUI.

My setup I'm using RealThunders 2023.05.21 release

Alternative solution is to use Realthunder's build. It doesn't have that limitation in addition to a whole bunch of other QoL additions.

As for your question, better to open a ticket on realthunder's Link repo: https://github.com/realthunder/FreeCAD/issues

I don't know for regular FC, but Realthunders Branch allows multiple solids in a PartDesign body, so with that one, you could use Multitransform to create a Mirror and linear pattern transformation (probably before adding the grooves for the links)
