![]() LibbreCAD can be installed and used in Linux, Apple and Windows platform. LibreCAD is used for creating technical drawings like plans for building, interiors and mechanical parts. LibreCAD is another free and open source CAD Software in 2 two dimensions. Once you are done with installation type freecad command from the terminal to start FreeCAD.

Blender is probably less lacking in features, but I found the operation anything but self-explanatory at first.For my purposes, the features of FreeCAD are enough, yet I guess there are certainly CAD programs with more features and a more intuitive user interface.OpenSCAD certainly can't be seen as a replacement for a CAD application, even though everything possible can certainly be implemented somehow via the scripting language.The cost of the open source programs is not the license fees, but the possibly longer learning curve. Conclusionįor constructions FreeCAD or OpenSCAD is suitable, Blender is suitable for modeling objects. ![]() Although the GUI has been optimized several times, it is still not really clear to me, this fact is probably due to the many possibilities that Blender has to offer.Ĭurrently, I use Blender mostly to modify existing STL files a bit, see as an example my glasses.ĭetails about the adaptation to my glasses: Why I didn't have to buy new glasses. Not being a regular user of Blender, it always takes me time to get the hang of it. Blenderīlender is an incredibly powerful program and in addition to modeling 3D objects, it can also render video sequences and even includes a video editing program. ![]() The sketch can first be simply drawn and later supplemented with lengths, angles, distances or constraints, making it an exact design.īack in the Part workspace, different parts from sketches or cylinders and cubes can be marked and subtracted from each other or edges rounded. For simple shapes like cubes, cylinders, or spheres I use the workspace: PartĬonstructions I usually start with a sketch in the "Part Design" area, which I later upholster. Admittedly, as a beginner I found it a bit difficult to use, but for constructions FreeCAD is still my first choice.Ĭurrently, I don't even begin to use all the features of FreeCAD. Starting from simple geometric shapes, to complex designs: FreeCAD is a free CAD program with all the essential features. Nevertheless, describing 3D objects via a script is more complicated than via a GUI for most tasks, which led me to FreeCAD. Having written certain scripts from time to time, it was not difficult for me to get started with OpenSCAD. One advantage of the script language is that variables can be used for the described elements and thus they can be adjusted centrally. To merge multiple objects into one, they can be joined with "union()", or subtracted from each other with intersection(). a cube with 15mm edge length: "cube(15)" or a sphere with 10mm radius: "sphere(10)". That means, each object is a function with certain parameters e.g. Objects are described in OpenSCAD using a simple scripting language. ![]() Starting with OpenSCAD, I later ended up with FreeCAD and Blender. The available CAD programs with OpenSource license can't really keep up with paid products of other manufacturers, nevertheless the thought to get along without license motivates me and therefore to rely on open source software. ![]()
