QymCAD
Open-source parametric CAD, real B-rep kernel, no cloud
What it does
QymCAD is a desktop parametric CAD for parts and assemblies: enclosures, brackets, mechanisms. A sketch becomes a solid via extrude, revolve or sweep; the solid gets holes, fillets, a shell, patterns. Parts form assemblies through joints - revolute, slider, rigid. Geometry is exact (B-rep), computed by the OpenCASCADE kernel - the same one FreeCAD runs on. STEP and STL exchange. No subscription, no cloud. Open source (AGPL-3.0), builds for Windows, Linux, macOS.
QymCAD is a desktop CAD for mechanical parts and assemblies. Sketch → part → assembly, exact geometry on the OpenCASCADE kernel, STEP exchange. No cloud, no subscription.
A parametric associative CAD on a B-rep kernel. Sketch → part → assembly. One program, one project file, no cloud and no subscription. No extra libraries are needed: OpenCASCADE and the dependencies are inside the package. The program works and is fit for real parts, but it is updated daily. The document format changes with no backward compatibility — a file from an earlier version may not open. The CNC (CAM) module does not work. Version v0.1.0-dev.20260828 of 28 August 2026 · what changed Unpack the archive anywhere and run qymcad.exe . No extra libraries are needed. A single AppImage file. Requires glibc 2.35 or newer: Ubuntu 22.04+, Debian 12+, Fedora 36+, Arch. An archive with the app.…from cad.qymis.tech

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
