v0.1.0-dev.20260828

A development build of QymCAD — a parametric CAD with sketches, assemblies and a B-rep kernel.

Downloads

Windows 10/11 x64 — qymcad-0.1.0-dev.20260828-win64.zip. Unpack anywhere and run qymcad.exe.

Linux x86_64 — qymcad-0.1.0-dev.20260828-x86_64.AppImage. Needs glibc 2.35 or newer (Ubuntu 22.04+, Debian 12+, Fedora 36+, Arch).

chmod +x qymcad-*.AppImage
./qymcad-*.AppImage

macOS 12+ (Apple Silicon) — qymcad-0.1.0-dev.20260828-macos-arm64.zip. New in this build.

The app carries no Apple signature, so macOS marks it as quarantined and says it is damaged. It is not. Clear the mark once, per download:

1. Unpack the archive.
2. Open Terminal (Command+Space, type "Terminal").
3. Type this, with a space at the end, and do not press Enter yet:

   xattr -cr 
   

4. Drag QymCAD.app into the Terminal window — the path fills itself in. Now press Enter. Nothing is printed in reply; that is how it should be.
5. Open QymCAD.app with an ordinary double click.

The mark does not come back after a restart. The same steps are in README.txt and ПРОЧТИ.txt inside the archive, in both languages.

What changed

• macOS builds — Apple Silicon, unsigned; see above.
• Start-up on a machine with no graphics driver — the program used to show a window for a moment and close without a word. A failed start is now reported, and an adapter backed by the processor is used rather than refused.
• The file chooser no longer holds the window — nothing was drawn while it stood open, and the desktop called the program "not responding". The interface behind an open system dialog is no longer clickable either.
• Saving twice gives the same file — two saves of an untouched document used to differ, which is poison for a format kept in version control.
• The window carries its own name and icon; the rebuild card no longer cuts off its own text.
• Dependencies — eframe and egui 0.29 -> 0.35, wgpu 22 -> 30, ron 0.8 -> 0.12, zip 2 -> 8, and the rest with them.

Known limits

The document format changes with no backward compatibility (convert_qcad.py brings older files forward). The CNC (CAM) module is groundwork and does not work yet. No Intel macOS build.
