Workbenches: As mentioned earlier, this software offers multiple workbenches with different sets of tools to work on different types of CAD projects. You can also perform conversions between the supported file formats. However, the main advantage of this software is its ability to support multiple 2D and 3D CAD file formats such as STL, OBJ, DWG, DXF, PLY, STEP, VRML, and more. Besides workbench specific tools, it also offers various viewing tools which help you view a 3D model from every direction. In each workbench, you will get a specific set of tools to create a specific type of 3D model. To work with different types of 3D models, it offers various different workbenches like Part, Drawing, Mesh Design, Raytracing, Robot, etc. Through this software, you can create and edit both 2D and 3D CAD models. FreeCADįreeCAD is a free open source 3D CAD software for Windows, macOS, and Linux. You can also check out the lists of best free Open Source CAD, CAD Software for Beginners, and CAD Viewer software for Windows. I also like its ability to support multiple CAD file formats like STL, OBJ, DXF, DWG, 3DS, and more. Plus, it offers a wide variety of editing and viewing tools. My Favorite Open Source 3D CAD Software For Windows:įreeCAD is my favorite software because it lets you create various different types of 3D designs like parts, ships, mesh, robots, etc. Go through the list to know more about these open source 3D CAD software. Some of the useful tools which you get in these software are Measure Distance, Unit Calculator, Scene Inspector, Color Palette, etc. Apart from important designing and viewing tools, you can also find various additional tools in these 3D CAD software which can come in handy. Once a 3D model gets completed, you can export it in various 3D file formats like STL, OBJ, DAE, DXF, PLY, etc. Using some of the viewing tools, you can also view both the internal and external structure of a 3D CAD model.Īfter designing and viewing a model, you can render your model to give it a realistic view, in some software. 
Apart from designing tools, you can also find various viewing tools (isometric view, top view, orthographic views, set camera, pan, zoom, etc.) in these software which help you view and analyze a 3D model. In order to create and edit an existing 3D model, these software offer various designing tools like building objects, wall objects, extrude, crease, flatten, intersect, transform tools, and a lot more.
In most of these software, you can also import and edit existing 3D models. Through these software, you can create both three-dimensional as well as two-dimensional CAD models. As these are open source 3D CAD software, thus you can download and make changes to their source codes without any restriction. Here is a list of best free open source 3D CAD software for Windows.
