Cap
surface node
Closes open areas with flat or rounded coverings.
See also: Poly Cap
This node caps meshes by extending the mesh in either the U or V direction (e.g. a NURBS tube). It caps faces by appending a separate face or hull cap.

This example shows how to cap two designated areas of a geometry by creating groups.
Two Group SOPs are used to create two groups, group_bottom and group_middle. These groups are created using Number Enable. The Pattern number corresponds to the primitive number, which you can see by turning on primitive numbers.
Two Cap SOPs are used to cap the two groups. By capping either the First V Cap or Last V Cap, you can select which end of the group you want to cap.

This example contains different variations on how to cap a tube.
There are three geometry types that are able to be capped – NURBS, mesh, and Bezier.
Each geometry type contains examples of different cap types – faceted, shared, rounded, and tangential.
For a better description of cap types, please open the help card in the Cap SOP.
