You can drag and drop the pre-made symbols from the left pane into your sketch window to complete a full diagram.įurthermore, Draw.io not only allows you to save your project to a web drive (Dropbox / Google Drive / …), but also to download it afterwards via PDF. In addition to standard symbols and blocks such as arrows, rectangles and shapes, there are specific technical symbols to choose from for many disciplines. With the help of the free web application Draw.io you can easily create technical sketches in your web browser without any installation.ĭraw.io is not only suitable for mechanical engineers, but also for architects, electronic engineers and computer scientists, for example. Place 3: Draw.io – create technical sketches online In my eyes, FreeCAD is comparatively easy to use. In addition, you can even perform full FEM simulations in both 2D and 3D! With the help of FreeCAD you can quite easily create technical drawings with all the usual features such as dimensions, fits, tolerances and surface specifications.įurthermore, with FreeCAD you can not only create 3D models and 2D drawings derived from them. ![]() ![]() Mireia Fernandez Cristia Updated 2 months ago The CAD Software You’ve Been Waiting ForįreeCAD is a free and open-source 3D CAD (computer-aided design) modeler meant for graphic design.The FreeCAD design software comes with modern user interface and is a versatile 3D and 2D drawing program. Intended for mechanical engineering product design, it dabbles much in computer-generated numerical modules and digital representations of the designs. However, FreeCAD can also be used in a number of other fields, such as architecture or electrical engineering. Since it is open-source, the coding of FreeCAD can be tweaked and improved upon even further by its dedicated community, by using the Python programming language. Free For AllįreeCAD has tons of features that make it so flexible to almost any type of designing.įreeCAD isn’t restricted to just one type of design it can generate-because of how general the 3D structures can be enhanced and evolved, its use can reach far and wide with the right application of coding. First, it has a complete Open CASCADE Technology-based geometry kernel, which allows complex 3D manipulations on various shape types so you won’t just be restricted to the preset ones you’ll find. This program has a full parametric model, meaning that the shape of the 3D objects you’re using can depend on either tweaked properties or other objects. You can add plugin extensions and different modules by scripts to add more functionality to the whole program. Importing and exporting to the standard formats for CAD is pretty easy, although it doesn’t cover full support of other formats. If you’re more hands-on with the 3D designs, you can use FreeCAD’s Sketcher, which lets you draw geometrical 2D shapes that you can use as bases for your objects to be built upon. There’s also a robot simulation module that lets you test robot movements in your design. It is software that enables architects, engineers as well as construction professionals to create accurate 2D as well. In terms of technical design, you also get the various features of rendering, architecture, and mechanical path machining for further testing and building. FreeCAD is a multi-platform program and has a full GUI for you to play with. ![]() ![]() You can run a command line on it and use your Python scripts when processing actions. As a CAD modeler software, FreeCAD is highly versatile, with great emphasis on the flexibility of features and how you can program almost anything on it.
