Constructive solid geometry (boolean operations).

FreeCAD can perform translation, rotation, scaling, mirroring, offset (either trivial or as described in Jung/Shin/Choi) or shape conversion, in any plane of the 3D space. can be created by specifying their geometry constraints. Primitive objects such as box, sphere, cylinder, etc. Since object relationships are maintained, the modification of one object will automatically propagate to any dependent objects. Those parameters can be modified and recomputed at any time. All objects in a FreeCAD document can be defined by parameters.

parametric associative document objects.

Modules behave like plugins in addition to delayed loading, individual modules can be added to or removed from an existing installation of FreeCAD. Almost all tools and geometry types are stored in modules.

FreeCAD is divided into a core application with modules that are loaded only when needed.

plugin/module framework for late loading of features/data-types.This allows you to display only the tools used to accomplish a certain task, keeping the workspace uncluttered and responsive, and allowing the application to load rapidly. In the FreeCAD interface, tools are grouped by workbenches. As in command line mode, the interface part of FreeCAD is unavailable, but all geometry tools are accessible. FreeCAD can be imported into any application that can run Python scripts. In this mode it has a relatively low memory footprint and can be used, for example, as a server to produce content for other applications. In command line mode, FreeCAD runs without its interface but with all its geometry tools.

FreeCAD has a complete Graphical User Interface based on the Qt framework, with a 3D viewer based on Open Inventor allowing fast rendering of 3D scenes and a very accessible scene graph representation. FreeCAD runs and behaves exactly the same way on Windows, Linux, macOS and other platforms.
