  • FreeCAD

  • FreeCAD is a general purpose parametric 3D CAD modeler. The development is completely Open Source (LGPL License). FreeCAD 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.FreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE. It is a feature based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.As with many modern 3D CAD modelers it has many 2D components in order to sketch 2D shapes or extract design details from the 3D model to create 2D production drawings, but direct 2D drawing (like AutoCAD LT) is not the focus, neither are animation or organic shapes (like Maya, 3ds Max, Blender or Cinema 4D), although, thanks to its wide adaptability, FreeCAD might become useful in a much broader area than its current focus.FreeCAD makes heavy use of all the great open-source libraries that exist out there in the field of Scientific Computing. Among them are OpenCascade, a powerful CAD kernel, Coin3D, an incarnation of Open Inventor, Qt, the world-famous UI framework, and Python, one of the best scripting languages available. FreeCAD itself can also be used as a library by other programs.FreeCAD is also fully multi-platform, and currently runs flawlessly on Windows and Linux/Unix and Mac OSX systems, with the exact same look and functionality on all platforms. »

  • Autodesk AutoCAD

  • AutoCAD is a software application for both 2D and 3D computer-aided design (CAD) and drafting — available since 1982 as a desktop application and since 2010 as a mobile web- and cloud-based app, currently marketed as Autocad 360.

  • nanoCAD

  • nanoCAD is a pro-grade 2D CAD system with native DWG support and full customizability. It is totally free, for business, professional, or personal purposes. It is fast, lightweight, capable, and , unlike most free CAD programs, completely uncrippled. nanoCAD includes:1. Classic CAD interface. Any engineer could easily master nanoCAD since everything is in their right places: menu, button icons, panels, command line, and the commands theirselves are easily recognizable. This makes nanoCAD easy to migrate to since enterprise needs no time to retrain its engineers.2. Native *.dwg support. The world’s most popular file format for technical documentation - *.dwg – is the nanoCAD native file format. Project created using nanoCAD and saved as *.dwg file could be easily opened and edited in any CAD application supporting *.dwg which in turn makes nanoCAD perfect tool for project collaboration and sharing.3. Ultimate design tool. nanoCAD includes all necessary tools required for basic design and allows creating and editing 2D and 3D vector primitives, texts, tables, blocks, graphical technical documentation display and print settings using either a model or a sheet. »

  • NaroCAD

  • NaroCAD is a fully fledged and extensible 3D parametric modeling CAD application.The goal of this project is to develop a fully fledged and extensible 3D CAD software based on the concept of parametric modeling of solids, comparable to well known solutions.These functionalities are interrelated through Model Associativity and are exposed through a GUI. The general usability specifications like saving, importing are described in General functionality specifications . The software can be extended through Plugins and programming interface. »

  • Designspark Mechanical

  • DesignSpark Mechanical is a 3D modeling software reported to be easy to use so that all engineers will be able to create and share models.Designs can be linked directly to RS/Allied off-the-shelf components for automatic bill of materials generation, part numbers, and costs for included components.DesignSpark Mechanical can export to DXF, SketchUp, ECAD, OBJ, STEP, and STL formats. Since the software is free, designs can be shared in native electronic form for providing 3D models to your customers and sharing with other engineers and management involved with the project. Designs can be sent directly to rapid prototyping/3D printer devices for quick prototyping. »
