  • FreeCAD

    This is the official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler.

    • I'm no longer a user of CAD programs so this might be a bit outdated. But for 2D take a look at QCAD. For 3D modeling and lots of other functionality you have FreeCAD.

  • LibreCAD

    LibreCAD is a cross-platform 2D CAD program written in C++17. It can read DXF/DWG files and can write DXF/PDF/SVG files. It supports point/line/circle/ellipse/parabola/spline primitives. The user interface is highly customizable, and has dozens of translations.

    • Also LibreCad.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
