![]() ![]() step version, as it will be easier to manipulate. Since we won't need to model any further now, it is best to choose the. step version, which will create only one object, without the history. FCStd version, which will load the full modeling history, or the. Load the IkeaChair file from the library.The FreeCAD library can easily be added to your FreeCAD installation (refer to the installing chapter of this manual), or you can simply download the model from the library webpage, or via the direct link provided at the end of this chapter. In the following exercise, we will see how to create a simple drawing of a chair model found in the FreeCAD library (Furniture -> Chairs -> IkeaChair). Finally, thanks to an addon called Drawing Dimensioning Workbench, you can also place all kinds of annotations on the sheet, such as dimensions, texts, and other usual symbols commonly used in technical drawings.ĭrawing sheets, once complete, can be printed or exported as SVG, PDF or DXF files. On these sheets, you can then place views of the 3D objects you modeled previously, and configure how these views must appear on the sheet. The Drawing Workbench allows you to create sheets, which can be blank or use a pre-made template containing pre-drawn items on the sheet, such as borders and title block. ![]() In FreeCAD, the workbench responsible for making such drawings is the Drawing Workbench. These drawings usually contain not only the drawing itself, but also many annotations, such as texts, dimensions, numbers, symbols that will help others to understand what needs to be done and how. Typical examples are Ikea instructions, architectural drawings or blueprints. In technical fields (engineering, architecture, etc), this is usually done with drawings, that are handed over to someone else explaining the designer's vision. FreeCAD itself can also be used as a library by other programs.įreeCAD is also fully multi-platform, and currently runs flawlessly on Windows and Linux/Unix and Mac OSX systems, with the exact same look and functionality on all platforms.When your model cannot be printed or milled directly by a machine, for example it is too big (a building) or it requires manual assembly after the pieces are ready, you will usually need to explain to another person how things fit together. Among them are OpenCascade, a powerful CAD kernel, Coin3D, an incarnation of Open Inventor, Qt, the world-famous UI framework, and Python, one of the best scripting languages available. It is a feature based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.Īs with many modern 3D CAD modelers it has many 2D components in order to sketch 2D shapes or extract design details from the 3D model to create 2D production drawings, but direct 2D drawing (like AutoCAD LT) is not the focus, neither are animation or organic shapes (like Maya, 3ds Max, Blender or Cinema 4D), although, thanks to its wide adaptability, FreeCAD might become useful in a much broader area than its current focus.įreeCAD makes heavy use of all the great open-source libraries that exist out there in the field of Scientific Computing. FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties.įreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE. The development is completely Open Source (LGPL License). FreeCAD is a general purpose parametric 3D CAD modeler. ![]()
