Section
Cross section (geometry)
Self Intersection
A condition where a curve crosses over itself (ex.'8','&'). This confuses geometric kernel algorithms and generally produces an error condition.
Shape
Generic term used in FreeCAD to describe most elements (except for meshes).
Shell
Shape made of two or more contiguous faces. A manifold (enclosed) shell can be converted into a solid.
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 elements and constraints.
Sketcher Solver
The internal FreeCAD mechanism that calculates inter-dependencies and effects of adding, deleting, and modifying geometry and associated constraints in each Sketch. Sketcher Solver also calculates the arrangement of all geometry in each Sketch so it can be displayed correctly.
Smooth Line
In a Drawing, a line indicating a change between tangent surfaces, as in the transition from a flat surface to a fillet. Also "tangent edge". See Drawing View
Solid
Part of 3D space bounded by Shells. A solid has a volume and other properties related to objects with a mass.
Solver
See Sketcher 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
An ISO standard (ISO 10303) for the exchange of 3D data and product manufacturing information. It replaces IGES. File extensions are *.step, *.stp.
SVG
Scalable Vector Graphics. A vector graphics file format.
Sweep
A 3D shape generated from at least one 2D cross-section that traces along a trajectory (path). Commonly used to define the tool as well as the created shape. See Solid modeling
