Open Asset Import Library(short name:Assimp) is a portable Open Source library to import various well-known 3D model formats in a uniform manner. The most recent version also knows how to export 3d files and is therefore suitable as general-purpose 3D model converter. See thefeature list. (The asset viewerapplication is Windows only Im afraid.)
AoIis a graphics-oriented 3D modeler thats written entirely in Java. can be used to output STL files. or addSkeinforgeto output GCode.
Although it is a 3D graphics design tool, it is also good for engineering design. It has a very easy and quick-to-learn user interface. AoI runs on Linux, Windows or Mac, and is freely available under the GPL.
AoI, for all its shortcomings, is probably the most used 3D modeling package in the RepRap community, primarily because of its very short learning curve. V2.7 experiences problems with booleans, and 2.6 is currently recommended – particularly with the CSG Evaluator plugin.
There is also a page onReprap-specific plugins for AoI.
Blender was originally intended for the same applications as AoI. It has a very efficient user interface, which includes a number of single-key keyboard commands. This is a very powerful and fast way of working, but can intimidate would-be users. (Dont be scared, blender is fun!) It may be arguably more powerful than AoI, and has a huge user community. Blender is scriptable in Python, runs on Linux, Windows or Mac, and is freely available under the GPL.
BlenderCAD is a pre-alpha attempt to build CAD functionality into Blender.
BRL-CAD is a cross-platform open source solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, image and signal-processing tools, a system performance analysis benchmark suite, libraries for robust geometric representation, with more than 20 years of active development. BRL-CAD runs on BSD, Irix, Linux, Mac OS X, Solaris, and Windows. BRL-CAD became an open source project in 2004, with portions licensed under the LGPL and BSD licenses.
The CadQuery language is a python-based language for building parametric 3D CAD models. The CadQuery software is very different from other 3D modeling software (except OpenSCAD) because it stores models in relatively human-readable script files that it later renders into STL, STEP, andAMF files. FreeCAD can be used as a CadQuery IDE.
EQUINOX-3Dis a free, advanced 3D modeling, CAD/CAM, animation and photorealistic rendering package. It runs great on Linux and a Mac OS version is in the works.
EQUINOX-3D has advanced polygonal, subdivision surface and spline-based 3D modeling, animation and photorealistic rendering.
It is (still) the only 3D package with a deeply integrated, interactive raytracer with global illumination. You can do modeling on a fast, ray-traced window, with the 3D user interface overlaid on the photorealistic image!
EQUINOX-3D is about 80% open source at the moment, working on a fully buildable source release.
It has many 3D printing, laser cutting, CAD CAM features. Its very powerful and user-friendly.
It has been recently updated, with a huge number of new features:EQUINOX-3D list of new featues
FreeCADis intended to be a full 3D mechanical engineering CAD package. It is still under development, but already usable.FreeCADis based onOpenCasCadeQTandPython, runs on Linux, MacOSX and Windows, and is freely available under theGPLandLGPL. It is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties and is oriented more toward technical drawings than freehand sketching–for example, you move objects by editing their XYZ coordinates.
However, it has a much friendlier learning curve than say,OpenSCADfor those who are unfamiliar with programming. It can also open some OpenSCAD models (OpenSCAD needs to be installed). Being Free as Freedom, it is more suitable to use than proprietary software asSketchup. There is a dedicated wiki page where the community shares various -FreeCAD resourceson tutorials, tips, cheats, any workarounds and so forth.
HeeksCAD, likeFreeCAD, is based onOpenCasCade, and has similar modeling functionality, with neutral IGES, STEP and STL file format exchange. Its much less dependent on parametric editing than FreeCAD and the GUI is more integrated, not modular. Its development has slowed down, and Windows installers have not been updated since 2011. The software needs to be compiled from source for Linux systems. Distributed under BSD license.
Inkscapeis an Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X. It uses the W3C standard Scalable Vector Graphics (SVG) file format. Inkscape is released under GPL Version 2.
There is a plugin for Inkscape which allows generation of gcode from a path. You may need to add nodes and then straighten all line segments before gcoding the path (then perhaps edit output files) to them work, as currently (Mar 2012) Sprinter wont interpret curves correctly, and some of the GCodes seem to make it freeze.Gcodetools
Another Plugin for Inkscape which is based on the Hershey Text Plugin for Inkscape, just with the option to place and customize Single-Line-Text in Layouts via .xml File. It make it easy to generate series of signs for example, with exact layout but different text. More Information can be found onthis Git-Hub Link
Another simple 3D modeler with no STL support.
LibreCAD is an application for computer aided drafting in two dimensions (2D). It is a fork of QCAD. you can create technical drawings such as plans for buildings, interiors, mechanical parts or schemas and diagrams. LibreCAD works on Windows, Mac OS X and many Linux and Unix Systems. The source code is released under the GPL.
OpenSCADis a scripted modeller which produces CSG (Constructive Solid Geometry) and 2D outlines. It is free software and available for Linux/UNIX, MS Windows and Apples Mac OS X. It supports DFX, STL and OFF file formats and is designed for the engineer not the artist. Can be used from the command line to generate bespoke STL objects. e.g. openscad -m make -s gears_helical.stl -D teethNum=15 gears_helical.scad
Quoting the official site The Persistence of Vision Raytracer (POVray) is a high-quality, Free Software tool for creating stunning three-dimensional graphics. The source code is available for those wanting to do their own ports. Shapes are described in scripts which are then rendered. Scripts can also render multiple stills which can be compiled into Ogg Theora videos using tools png2yuv and ffmpeg2theora. Good online documentation is available on the official site.
Built on top of pythonOCC, OpenCascade, numpy and scipy,pyGearserves as an CAE/CAD-preprocessor generator ofinvolute gears.
A python wrapper for theOpenCascadeand Salome (salome-geometryandsalome-mesh) libraries. Supports constructive solid geometry, data exchange, meshing, GUI development (wxPython, PyQt, python-xlib), parametric modeling. FEM solver integration with (Code Aster) is underway. (Not a GUI based CAD program, but aims to be a scripting framework for rapid development of custom CAE solutions.)
QCAD is an application for computer aided drafting in two dimensions (2D). With QCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schemas and diagrams. QCAD works on Windows, Mac OS X and many Linux and Unix Systems.

Many of the programs on this page generate files in SVG or DXF or Gerber format.Builders/Replathimports files in those formats and produces standard G-code files and standard SVG files (and a few other formats).
Onshape is the first and only full-cloud 3D CAD system that lets everyone on a design team simultaneously work together using a web browser, phone or tablet. Onshape is a complete parametric CAD system, which means that changing a models underlying dimensions or placement of features or dimensions of features can be made at any time without damaging the integrity of the model. The free version of OnShape provides 100% of the functionality of the professional version, but limits each user to 5 active documents.
