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.
CADauno is a 3D modeling tool based on the NURBS surfaces. It aims to exploit the power of NURBS at representing free forms. It provides an interpolation facility ("skinning" technique), which enables the designer to create a closed surface passing through different section curves. This makes it possible, as an example, to build a human body 3D model starting from sections provided by a Computed Axial Tomography scanner.
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.
Gmsh is an automatic 3D finite element grid generator with built-in CAD and post-processing facilities. Its design goal is to provide a simple meshing tool with parametric input and advanced visualization capabilities. It is built around four modules: geometry, mesh, solver, and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface (based on FLTK and OpenGL) or in ASCII text files using Gmsh's own scripting language.
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.
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.
