Translations:Sandbox:What is FreeCAD/2/en

FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeling application, made primarily to design real-life objects. Parametric modeling is a type of modeling where the shapes of the 3D objects you design are controlled by parameters. For example, the shape of a brick might be controlled by three parameters: height, width and length. These parameters are part of the object and may be modified at any time, even after the object has been created. As well as simple values, an object can have other objects as parameters. For example, you could have an object that takes your brick as input and creates a column from it. You could think of a parametric object as a small program that creates geometry from parameters.
