# Create, Edit, Query Geometry

Create, edit, and query various geometric features, such as nodes, points, line, and surfaces.

Create, edit, and query various geometric features, such as nodes, points, line, and surfaces.

**Nodes**

Nodes are the most basic finite element entity. A node represents a physical position on the structure being modeled.**Points**

A point is a zero-dimensional geometric entity.**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.**Surfaces**

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**

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.**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.
