Pad: An extension of a Sketch in a direction perpendicular to the plane of the Sketch. See also Extrude. Part: A FreeCAD Workbench primarily used for a Constructive Solid Geometry workflow. A unibody solid. The lowest level component in an assembly. Perspective:

Pocket: A Feature that removes material from a solid based on a Sketch. Point: An item used to reference a single area in the 3D workspace. A “point” is dimensionless. It has a dimension on the screen, usually represented by a “dot” only so we can see where it is. See also Vertex. Polygon mesh:

Shape:

Sketch: A constrained 2D depiction of an object fixed to a plane or a Face. In FreeCAD a Sketch is always a 2-dimensional object somewhere in the 3D space. Sketcher: A workbench used to create 2D geometry by use of constraints. Sketcher Solver:

Solver:

Stable: A nickname for the last general release version of the FreeCAD software. This is typically the version available from sources other than the FreeCAD project. Compare with Unstable. STL: STereoLithography, also known as Standard Tessellation Language. A mesh file format defining only the surface of a 3D object. File extensions is *.stl STEP:

SVG: Scalable Vector Graphics. A vector graphics file format. Sweep:

Thickness:

A Part Workbench tool to hollow out a solid and leave a defined uniform thickness. Toggle:

Torus: A primitive shape. Tracker:

U

Unstable: A nickname for a very recent version of the FreeCAD software. This version will contain many changes recently implemented by the developers. It does not typically fail or produce wrong results, but it has not completed testing. Upgrade:
