WireViz is a suite of tools for documenting electrical connections, converting wire gauges, and producing bills of materials and diagrams. It functions as a text-to-diagram framework that converts descriptions of cables and pinouts into graphical wiring harness diagrams and technical specifications. The system includes a wiring harness diagramming tool that generates SVG or PNG files from text descriptions and a wiring BOM generator that produces comprehensive bills of materials for cables and electrical harnesses. It also features an electrical wire gauge calculator for converting thickness

foxBMS is a free, open and flexible development environment to design battery management systems. It is the first modular open source BMS development platform.

FreeCAD is an open-source engineering design suite designed for parametric 3D modeling, architectural planning, and mechanical assembly. It functions as a professional-grade platform that utilizes history-based operations to allow for non-destructive design updates, enabling users to construct complex geometry through a sequence of constrained sketches and solid operations. The platform distinguishes itself through a highly modular, workbench-based architecture that allows users to tailor the interface and toolsets to specific engineering domains. It features deep Python integration, which se

Here you'll find a growing collection of 3D models, textures, and images from inside NASA.

A model generator for energy system modelling and optimisation (LP/MILP).

OpenSCAD is a script-based 3D modeler and parametric CAD tool that generates three-dimensional solid objects from programmable scripts. It utilizes a constructive solid geometry engine to create complex shapes by performing boolean operations on basic geometric primitives. The system functions as a compiler that transforms a functional language into geometric representations, allowing for precise dimensional control through variables and functions. It features a WebAssembly implementation that enables the geometry pipeline to execute directly within web browsers. The software covers a broad
