Description

FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization.

FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

Features

  • Rock-solid OpenCasCade-based geometry kernel, allowing complex 3D operations on complex shape types, and supports natively concepts like brep, nurbs, booleans operations or fillets
  • Full parametric model allowing any type of parameter-driven custom objects, that can even be fully programmed in python
  • Complete access from python built-in interpreter, macros or external scripts to almost any part of FreeCAD, being geometry creation and transformation, the 2D or 3D representation of that geometry (scenegraph) or even the FreeCAD interface

    I've downloaded and installed FreeCad on a Windows 8 Platform but I am unable to open the program to start using it. Can you please help

    I've been using it for a few weeks now. It started out promising and I was able to make some good models for 3D printing. Then I hit a wall trying to do boolean operations. Apparently the OpenCasCade library that FreeCAD uses for booleans is not too robust. The end result is that I can't get the results I want which ultimately makes this a dead end for me. I'll keep using it for basic work, but I would never promote this to my peers/colleagues as a tool that gets real work done. I'll change my review when I can get consistent/quality results from boolean ops.

    600 5 star ratings <-- haven't used a professional parametric 3D cad program. 150 1 star ratings <-- have used a professional parametric 3D cad program. A shovel is a godsend if you were digging with your bare hands. It kind of sucks if you had an excavator. FreeCAD is nowhere near professional 3D cad software such as Solidworks or Autodesk Inventor, which cost thousands of dollars/euros. Features are sparse, ui is clumsy. But it's free. I tried to give this 2/5, but I honestly cannot. For I have used professional 3D cad software.

    I discontinued Autocad and tried Freecad do continue drawing my house in 3D. I tried to move objects and extrude planes, and create walls... nothing was possible?? When I click a plane I can not extrude it.. the extrude button stays grayed out??? I have tried all kind of options for 20 minutes. Nothing works. Maybe this program actually is capable of doing anything, but the user interface makes it impossible to use. I am happy to teach the programmers how to make it user friendly. Terrible software. I can not use it.

    Promising. But at this point on my Mac only promising. As the old adage said: "If it sounds too good to be true, that in fact is probably the case!" Best of Luck.
