What else is out there?
You don't have to limit yourself to Tinkercad and Fusion 360 as your only 3D Modeling tools. There is a wide variety of other software out there, and some of it may be better suited to the specific project you have in mind. On this page, we'll list some of our favorite freely available options, as well as some pros and cons to help you decide whether these tools are right for you.
Free 3D CAD tools
Like Fusion 360, these tools are best for creating objects based on measurable dimensions and geometrical parameters.
SketchUp: Developed by Trimble, SketchUp is an easy-to-use 2D and 3D Drawing tool that excels at architectural drawings, but can handle a variety of other geometry as well. SketchUp comes in two versions: the free SketchUp Make, and SketchUp Pro, which offers additional features for a price.
FreeCAD: FreeCAD is a 3D modeling software that uses history-based design to allow you to make changes to an object by editing a the parameters of its components.
Free 3D Sculpting Tools
Polygonal Modeling refers to the art of creating objects out of many small triangular facets. Polygonal modeling tools excel at creating organic shapes like faces, creatures, scenery, and sculptures. If you want to make a character or object for a video game, an animated movie, or a lifelike miniature for a tabletop game, you'll want to use a polygonal modeling tool.
Blender: Blender is the go-to free and open source 3D media creation suite. It's not just a sculpting tool. Blender supports the entirety of the 3D creation pipeline - modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation.
Meshmixer: What started out as an experimental product from Autodesk has now become a very capable introductory 3D sculpting and mesh-repair tool. You can use Meshmixer to create fun simple creatures by mashing together premade parts or sculpt objects from scratch. You can also use its Inspector feature to clean up the gaps and cracks left by a 3D scanner.
Sculptris: Developed by Pixologic, the makers of Zbrush, which is one of the most widely used professional 3D sculpting tools, Sculptris is a simple, lightweight application that can serve as your gateway to digital 3D art.
