- I use Freecad to design my 3D printing models. Guest • Oct 2015 • 8 agrees and 4 disagrees
- Freecad is (as mentioned in the description) for 3D parametric CAD, and has no drafting functionality worth speaking of. Not a bad program, but certainly not an AutoCAD replacement. It has much more similarity to SolidWorks than AutoCAD Guest • Jan 2017 • 10 agrees and 6 disagrees
- Not directly supporting DWG: needs a commercial/trial license of a file converter Guest • Apr 2017 • 2 agrees and 2 disagrees
- Very good app, has many workbenches for different branches of engineering. It has a very helpful community forum. I really recommend trying it before looking for any other alternative. Guest • Jun 2017
- Not bad for a free Software, but Workflow seems very antiquated and unneccessarily complicated. It lacks logic on available tools in different workbenches. There are much ways to get to your goal but every way takes really a lot of clicks and more of trial and error. Guest • Aug 2017 • 2 agrees and 2 disagrees
- AutoCAD is a 2D drawing program, mostly used for architecture and structures. FreeCAD is 3D and aimed at mechanical engineers. They do different things. Guest • Feb 2018
- Because is an user friendly software and is free to use.Autodesk Autocad is very expensive eduardoortiz1 • Mar 2018 • 0 agrees and 1 disagrees
- FreeCAD is not a bad program, but it seems to lack functionality that AutoCAD provides. Currently FreeCAD seems to be in an early stage of development, and should probably not be considered for use in a professional production context, as a replacement for AutoCAD.

- FreeCAD is a software for 3d parametric model, AutoCAD is not that. Guest • Sep 2015 • 0 agrees and 6 disagrees

- LibreCAD is only a 2d Drafting software while AutoCAD also has 3d modelling capabilities Guest • May 2016 • 4 agrees and 6 disagrees
- Similar GUI like AutoCAD, and for 2D drawing, it is a perfect solution Guest • Jul 2017 • 0 agrees and 2 disagrees
