I create almost all of my 3D designs with FreeCAD. It’s a free 3D parametric modeler. I create(d) a lot of tutorials about FreeCAD, so you can start learning now at the AllVisuals4U video channel!
It’s very adjustable to your needs, because there are many so called workbenches, which have tools for many specific disciplines in 3D design, like fasteners or specific part design.
FreeCAD may not be the easiest way to design your 3D models, but if you’re dedicated to learn this software, i think you will really like it! The concept of this software is that it’s a parametric 3D modeler. So every object created is captured by features and constraints. It’s open source and developed by only a few people and developers who contribute to the software. You shouldn’t compare FreeCAD with paid software, but as a free software, FreeCAD is awesome! The video in this post will give you a quick impression of how FreeCAD looks like.
