Extrude

The ExtrudeCrv command creates a surface by tracing the path of a curve in a straight line.

Steps

1. Select a curve.

2. Specify a distance.

Command-line options

Output

• Surface: Create an extrusion or a surface object

• SubD: Create a SubD object.

  • A SubD friendly curve as the input creates a better SubD object.

  • Some options may not be available when Output=SubD.

Direction: Pick two points to define the extruding direction.

BothSides: Extrude towards the both sides of the input curve.

Solid: If the profile curve is closed and planar, both ends of the extruded object are filled with planar surfaces and joined to make a closed polysurface.

ToBoundary: Extrude the object to a boundary surface.

DeleteInput: Specify if the input object will be deleted.

SplitAtTangents

• Yes: Tangent points on the input curve extrude as joined edges.

• No: Tangent points on the input curve extrude as surface kinks.
