CAD software is a must-have tool to have in most enterprises to reduce fatal flaws in design that may show up during production. If you're in the industry that
1. Sculptris
Sculptris is a professional yet free 3D modeling program that is made by one industry 3D expert, Pixologic. You can use it to easily design your own version of a troll, dragon, or even Godzilla itself through their rich sculpting toolset. If you’re bad at playing around the geometry and polygons to create your own surface, worry not, because Sculptris surface contains countless of triangles that are automatically built into your 3D model surface.
2. SketchUp Make
One of the most popular 3D modeling software, SketchUp Make, is used mostly for architectural purposes and sometimes for other niches in the 3D design market. If you’re looking for a complete 3D modeling software for your professional career with all the tools included, minus the price tag, then SketchUp is for you. Take a look at SketchUp 3D Warehouse for a lot of amazing content (created by SketchUp users) which you can download, and at the same time, see what the software is capable of.
3. DraftSight
DraftSight is a free 2D CAD editor that is good for professional CAD users, students and educator, especially if you need to create, edit and view your project in the native DWG file format. It comes with a nice set of features that allows you to generate professional looking plans using lines, polylines, dimensions, text and others. The interface is relatively dull, but this may appeal to those who prefer a minimalist and simple CAD software.
4. FreeCAD
This project is 100% open source and is aimed directly for mechanical engineering and product design uses, but also can be used for architecture or other engineering industry that relies a lot on parametric 3D modeler. Although it is open source and free, FreeCAD is on par with other popular CAD programs due to its capability in creating real 3D solids, support for meshes, 2D drafting, right hand coordinate system plus many more features. The program itself is extremely modular, where you can opt for very advanced extension and customization.
