Cap SOP

Summary

The Cap SOP is used to close open areas with flat or rounded coverings. Meshes are capped by extending the mesh in either the U or V direction (e.g. a NURBS tube). Faces are capped by appending a separate face or hull cap.

capSOP_Class

Parameters - Page

Group group - Specify the Primitive Group to apply the caps to. See Group SOP to create primitive groups.

Parameters - U Caps Page

Preserve NURB Shape U pshapeu - When capping a NURBS surface, use this option to preserve the original surface by clamping it at the point of capping.

First U Cap firstu - ⊞ - Select an option from the menu:

• No End Cap none - Leave this side of the primitive unaffected.

• End Cap Faceted facet - Cap by creating a face of a similar type which uses unique points.

• End Cap Shared share - Cap by creating a face of a similar type which shares points with the original primitive.

• End Cap Rounded round - Cap by creating / extending a mesh containing a number of concentric circular regions. This creates a bullet or domed shaped cap.

• End Cap Tangential tangent -

Divisions divsu1 - Number of cross sections in the rounded cap.

Scale scaleu1 - Affects the height of the rounded cap (both positive and negative).

Last U Cap lastu - ⊞ - Similar to First Cap U / V, but builds a cap on the other end of the primitive in the opposite direction.

• No End Cap none -

• End Cap Faceted facet -

• End Cap Shared share -

• End Cap Rounded round -

• End Cap Tangential tangent -

Divisions divsu2 - Number of cross sections in the rounded cap.

Scale scaleu2 - Affects the height of the rounded cap (both positive and negative).

Parameters - V Caps Page

Preserve NURB Shape V pshapev - When capping a NURBS surface, use this option to preserve the original surface by clamping it at the point of capping.

First V Cap firstv - ⊞ - Select an option from the menu:

• No End Cap none - Leave this side of the primitive unaffected.

• End Cap Faceted facet - Cap by creating a face of a similar type which uses unique points.

• End Cap Shared share - Cap by creating a face of a similar type which shares points with the original primitive.

• End Cap Rounded round - Cap by creating / extending a mesh containing a number of concentric circular regions. This creates a bullet or domed shaped cap.

• End Cap Tangential tangent -

Divisions divsv1 - Number of cross sections in the rounded cap.

Scale scalev1 - Affects the height of the rounded cap (both positive and negative).

Last V Cap lastv - ⊞ - Similar to First Cap U / V, but builds a cap on the other end of the primitive in the opposite direction.

• No End Cap none -

• End Cap Faceted facet -

• End Cap Shared share -

• End Cap Rounded round -

• End Cap Tangential tangent -

Divisions divsv2 - Number of cross sections in the rounded cap.

Scale scalev2 - Affects the height of the rounded cap (both positive and negative).
