Their tagline captures it best: 'The programmers solid 3D CAD modeler.' So, it makes it the more technical package in this list, but it has great reviews. OpenSCAD is popular, but different than the other packages mentioned above in that it does not focus on the artistic side of 3D modeling, but on the CAD-specific approach. FreeCAD is open source (LGPL license) and completely modular, allowing for very advanced extension and customization. Most often this is from a dimension – you can change the parts or components graphically by dragging the corner of an object, for instance, but you can also just enter in a numerical change and it will adjust the model accordingly. Files can be saved for 3D printing, of course.įreeCAD is what is known as a parametric 3D modeler, as in, the software allows you to modify designs by changing parameters, such as, dimensions or density. There are advanced features in Tinkercad and small business owners are using it to design and create complete products. Tinkercad is viewed as a basic, kid-friendly, 3D modeling app, but it is much more than a simple web app and more robust than most people realize.

There is a learning curve for any new software package you decide to use, but here are four that are considered some of the easiest to learn and use.

Fortunately, there are many free 3D computer-aided design (CAD) packages available (web-based and downloads) to help get your prototype started and ready for production. 3D design is often considered a difficult and costly endeavor for those with an invention idea - either you have to buy expensive software, or hire a qualified modeler or designer.
