OCE (OpenCascade Community Edition) is a community version of the OpenCascade Technology 3D kernel, a C++ library for 3D CAD development. It includes components for 3D surface and solid BRep modeling, visualization, data exchange (STEP, IGES), and rapid application development. OCE aims to fix bugs and improve code quality and portability.
gCAD3D is a 3D CAD-CAM application which features an integrated 3D OpenGL viewer, a program interpreter for geometry and NC-commands in 3D, and a programming interface for user programs. It has support for importing Step files and support for both importing and exporting Iges, DXF, and VRML files.
QSapecNG (Symbolic Analysis Program for Electric Circuits (New Generation)) is a Qt-based program for symbolic analysis of linear analog circuits. It consists of two independent parts, the SapecNG framework engine and the QSapecNG GUI. It was based on SapWin. Users can draw, solve, analyse, and manage analog circuits.
pythonOCC is a 3D CAD/PLM development library for the Python programming language. It provides 3D hybrid modeling, data exchange (support for the STEP/IGES file format), GUI management support (wxPython, PyQt, python-xlib), parametric modeling, and advanced meshing features. pythonOCC is built upon the OpenCASCADE 3D modeling kernel and the salomegeom and salomesmesh packages. Some high level packages (for parametric modeling, topology, data exchange, webservices, etc.) extend the builtin features of those libraries to enable highly dynamic and modular programming of any CAD application.
CAD Scripts automates a range of CAD tasks. It includes text_to_dxf for drawing figures in DXF format by specifying co-ordinates in an input text file.It also includes support for automatically create an entire beam and column structure for FreeCAD or StadPro after entering the specifications of a building.
DXF Export Java is a Java library for exporting CAD entities, along with their properties, to stream or AutoCAD DXF files at high speed and with ease. Creating a new DXF file takes only one call of the exporter class, provided that user data has been prepared and loaded to the required fields beforehand. The library handles all major entities, including Arc, Bezier, Circle, Ellipse, Hatch Pattern, Line, Multi-line Text, Pixel, Polyline, Rectangle, and Text. It also supports layers, colors, line styles, and other important properties. Source code and working demos are included.
gEDA is a suite of electronic design automation (EDA) tools. Currently, the project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.
OSG composer was designed to unleash the potential of OSG developers and users. It facilitates the creation of simple to complex 3D scenes, which combine geometries from different sources. It lets you add models from different sources, place them visually using the draggers, use advanced Snap tools, add 3D text to your scene, add texture coordinates to the models, duplicate and create instances of geometries in the scene, automatically pack your scenes with all its textures in a zip file so you can share it with other users, and fix problematic models and bring them back to life.
