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.

  • 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

    Game is too complex. Too many units, too many weapons, too many upgrade paths. Cannon, machine gun, dual machine gun, flame, heavy flamer, rocket, mini-rocket array, on and on and on. One of the team colors in dark the fog of war so you can't even see where your units are. These developers must not even play their own game.

    It's a good real time strategy game.

    I've been playing this game since before 2.3.9 back in 2010/2011 or so. The game was fun then, and the improvements since then have been awesome. It's a real-time strategy game that came out in the late 90s and has been open source for several years now. This game requires no super technical knowledge to install or run. Just download, install, run. That simple. For quick reference, it runs very smoothly on Windows 7 at 1080p resolution on a 6 year old Core2Duo CPU at 2.13 Ghz with 4 GB of RAM. Graphics are scaled properly to nearly any resolution you have, so it's not like trying to play an old DOS game at 1080p (yuck). The community on is helpful and plenty of common questions have already been answered on the forums there. There are usually 1 or 2 online games available in the multiplayer lobby, and it's easy to network the game on a home network, even cross-platform (Mac/PC) as long as you have the same version of the game installed on all machines connecting. If you like the basic gameplay, I totally recommend getting some map mods for the game to make things more interesting, although a good number of maps come with the game. It also has a campaign mode (with or without videos, it's up to you) for people who like that. Multiplayer (or skirmish) matches are quite customizable as far as difficulty and other options. There's lots more to say about the game, but I just wanted to give you some solid reasons to play it. So give it a go. :)
