A surface represents the geometry associated with a physical part. A surface is a two-dimensional geometric entity that
may be used in automatic mesh generation.
Solids are closed volume of surfaces that can take any shape. Solids are three-dimensional entities that can be used in
automatic tetra and solid meshing.
A face is a single Non-uniform Rational B-Spline (NURBS) and is the smallest area entity. It has a separate underlying
mathematical definition, specified when it was created.
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Points and Nodes
Learn about creating, editing, and extracting points and nodes.
Shapes
Create and edit circles and rectangles with the Shapes tool.
Lines
A line represents a curve in space and is not attached to any surface or solid. A line is a one-dimensional geometric entity.

Solids
Solids are closed volume of surfaces that can take any shape. Solids are three-dimensional entities that can be used in automatic tetra and solid meshing.
Create Ruled Surfaces and Solids
Use the Ruled tools to create surfaces/solids by interpolating lines and surfaces either linearly or smoothly.
Faces
A face is a single Non-uniform Rational B-Spline (NURBS) and is the smallest area entity. It has a separate underlying mathematical definition, specified when it was created.
Drag and Spin
Use the Drag/Spin tool to drag and spin lines, surfaces, and nodes in order to create surfaces or solids.
Midlines
Use the Midlines tool to create midlines from existing lines, surface edges, or tube solids.
Midsurface
Extract the midsurface of thin solids, and review and edit midsurface plates.
