- Face
- A 2 dimensional topological construct. For example, a cube has 6 Faces. A face can be curved, like in case of a sphere, which has one face in FreeCAD. The CAD kernel defines it as: Part of a surface bounded by a closed wire(s). See Profile: Defining the Topology.
- Facet
- Often used to describe planar faces on a mesh.
- FC
- Short for FreeCAD.
- FCStd
- FreeCAD native file format. File extension *.fcstd, *.FCStd
- Feature
- A step in a 3d part's evolution in the Part Design workbench workflow. Examples are Pad, Pocket, Groove, Fillet, etc. As we create a model in the Part Design workbench, each feature takes the shape of the last one and adds or removes something. Hence a "Pocket" feature is not only the pocketed hole itself, but the whole part with the pocket feature.
- FEM
- Finite Element Method, a workbench used to solve engineering and mathematical physics problems associated with parts, assemblies and structures.
- Fillet
- A rounded relief or cut at an edge added for a finished appearance and to break sharp edges. See Part Fillet and PartDesign Fillet.
- Fork
- See Forked Model.
- Forked Model
- A modeling method, usually accidental and incorrect in FreeCAD, that creates two or more versions of a model from a previous item. (Not to be confused with intentional operations like Array, Clone, Polar Pattern, etc.)
- Frenet
- When Sweeping a profile along a 3D path, the Frenet parameter controls the orientation of the profile as it travels along the path. If Frenet is true, the profiles are oriented using the Frenet Frame (tangent, binormal, normal) of the path. If Frenet is false the profile's rotation is not restricted. Frenet frame
- FreeType
- A freely available software library used to extract information from font definition files.
- Frustum
- The portion of a solid that lies between two parallel planes cutting it. Used in computer graphics to describe the three-dimensional region which is visible on the screen, the "viewing frustum"
- Fully Constrained
- In Sketcher, when a Sketch has no Degrees Of Freedom, the Sketch is said to be "fully constrained" by the applied Constraints.
- Fuse
- Term commonly used in FreeCAD to refer to a boolean union of shapes.
