Explore the tools used to create geometry.

**Points and Nodes**

Learn about creating, editing, and extracting points and nodes.**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.**Midlines**

Use the Midlines tool to create midlines from existing lines, surface edges, or tube solids.**Shapes**

Create and edit circles and rectangles with the Shapes tool.**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.**Extract Midsurfaces**

Use the Midsurfaces tool to extract the midsurface of sheet metal stampings, molded plastic parts with ribs, and other parts that have thickness clearly smaller than width and length.**Drag Geometry**

Drag surfaces, nodes, or lines along their normal direction, a vector, or another line.**Create Ruled Surfaces and Solids**

Use the Ruled tools to create surfaces/solids by interpolating lines and surfaces either linearly or smoothly.
