Open Source CAD Software

PythonCAD is a CAD package written, surprisingly enough, in Python using the PySide2 interface and python3. The PythonCAD project aims to produce a scriptable, open-source, easy to use CAD package (Cross Platforms)

CFD code using Arbitrary Lagrangian Eulerian algorithm.

Varias herramientas para automatizar tareas en Revit: 1) Creador automático de Montajes 2) Crear vistas a partir de una Caja de Referencia

XFloorPlan is a 2D home design software. You can resize, rotate, customize, and glue shapes together.

Session wrapper is a tool which makes using animator session file easier. This allows a reusable session file to be run multiple time and also allow easy selection of the variable values. This tool is still in development phase and still a lot of updates are to come with upcoming versions.

A project for providing Mac OS X binary packages of open source CAE (computer aided engineering) tools.

FAST is an Analysis and Simulation Toolbox (FAST) for Fuel Cells (FC) FAST-FC is the doctorate work of David B. Harvey and was developed with support from the U.S. DOE, Ballard, and Queen's University. Derivative works of FAST-FC include FC-APOLLO which is a forked branch of this project intended to capture the code state at the exit of the funded DOE project. FAST-FC is the open and active community branch. FAST-FC is developed and maintained by the original creator and developer, David B. Harvey. Features of FAST-fc include transport of gases and liquids, multi-step reaction kinetics, transient and steady state operation for performance and durability, and scalable dimensionality from 1D - 3D domains. Future development work is on-going in FAST-fc and our strategic development schedule includes membrane degradation, improved liquid water transport models through the application of pore networks, and extension to stack-level simulation.

A tool for CNC toolpath generation. Model data in, G-Codes out. The system is kept as generic as possible. Machines with up to 9 axis can be defined. Machine simulator included.

A free, multi-layered, multi-license cad engine. You are free to use the core classes.

MCF - Models Construct Framework

Shoe design software. Based on foot measurements or a foot scan. Generates a bone based or a last based model. Supports different styles of shoes. Pattern editor for the upper. Calculates flattening of the design.

A java based editor for creating 3D indoor environments based on 2D input.

Software for the design and verification of railway interlocking systems.

Yet Another Computer-Assisted Design software

baramonweb은 php로 구현된 웹어플리케이션으로 웹 기반의 OpenFOAM 사용자환경입니다. OpenFOAM 입력 파일 생성, 솔버 및 유틸리티 구동을 지원합니다.

freeware converter autocad (.dxf) file to gerber (.gbr). Currently dxf 2010 is partly supported. Feel free to contribute patches/extensions.

This software born with the purpose to help Cad software, mainly for mechanical designers that doesn’t have an easy predisposition on their software to doing the weight estimation.

A 3D only CAD/CAM program for generating CNC code from existing models. The focus is on importing an existing 3D model (STL files) and providing basic manipulation capability, like rotation, scaling, etc. It does not support building 3D models from scratch. GCode and Shoptbot toolpaths are generated from the model. Multithreaded. This is a standalone companion product to the Techne (R) CAD/CAM project.
