Points and vertices

Geometry attributes

Describes how Houdini represents geometry using details, primitives, points, vertices, and attributes.

Groups

Volumes

Create geometry

Edit geometry

Edit components

Reselect geometry

In Houdini you can not only edit the parameters of a surface node, you can reselect the geometry the operation applies to.

Polygon shelf tools

Tools on the Polygon tab let you modify polygons in the scene view.

Model shelf tools

Tools on the Model tab let you edit objects in the scene view.

"Box up" modeling

Mirror geometry across a symmetry plane

Repair polygonal models

Modeling aids

Trim NURBS surfaces

Import geometry from other objects

Create, edit, and use Null objects

"Curve up" modeling

Geometry appearance editor

The appearance editor mode of the data tree pane lets you edit various controls for object viewport/rendered appearance in one place.

Locking geometry nodes

Packed primitives

Looping in geometry networks

Compiled blocks

You can mark a chain of compilable SOPs as a compiled block which can execute much faster in parallel.
