Sculptris
Sculptris provides an excellent gateway into the exciting world of 3D. It’s features are easy to learn, even for someone with no experience in digital art, yet robust enough for creating base models that can then be refined in other applications, such as ZBrush.
SketchUp Make
SketchUp users are architects, designers, builders, makers, and engineers. They are the people who shape the physical world. They are important, and they deserve great tools because great tools produce great work.
At SketchUp, we do our best to make great tools for drawing. For our users, drawing is thinking. They draw to explore ideas, to figure things out, to show other people what they mean. They draw because they love it, and because nothing great was ever built that didn’t start with a great drawing.
DraftSight
[Download: Windows 32-bit, Windows 64-bit, Mac, Ubuntu, Fedora]
DraftSight has a familiar user interface and a minimal learning curve that facilitates an easy transition from your current CAD application.DraftSight allows you to access existing DWG files and create new ones at a fraction of the cost of alternative CAD products.
FreeCAD is a parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD is open-source and highly customizable, scriptable and extensible.
OpenSCAD
[Download: Windows, Mac, Linux]
OpenSCAD is a software for creating solid 3D CAD models. It is free software and available for Linux/UNIX, Windows and Mac OS X. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.
KiCAD
[Download: Windows, Mac, Linux, Ubuntu]
KiCad is an open source software suite for Electronic Design Automation (EDA). The programs handle Schematic Capture, and PCB Layout with Gerber output. The suite runs on Windows, Linux and OS X and is licensed under GNU GPL v2.
QCAD
[Download: Windows, Mac, Linux]
QCAD is a free, open source application for computer aided drafting (CAD) in two dimensions (2D). With QCAD, you can create technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams. QCAD works on Windows, Mac OS X, and Linux. The source code of QCADis released under the GPL version 3 (GPLv3), a popular Open Source license.
LibreCAD
[Download: Windows, Mac, Linux]
LibreCAD is a free Open Source CAD application for Windows, Apple and Linux. Support and documentation is free from our large, dedicated community of users, contributors and developers.
3DCrafter
[Download: Windows]
3DCrafter is a real-time 3D modeling and animation tool that incorporates an intuitive drag-and-drop approach to 3D modeling.
Complex models are constructed from simple 3D primitives or created using 3DCrafters Shape Building Tools. Modeling tools are provided to deform, sculpt, and paint 3D shapes.
NanoCAD
[Download: Windows]
NanoCAD is a professional grade CAD tool. It has a familiar interface, powerful drafting and design tools, native DWG compatibility, and an open API. Moreover, it is totally free to use and share. No catches, no gotchas, and no compromises.
