Extrude Curve

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

Extrude curve

Steps:

1. Select a curve.
2. Specify a distance.

Notes

• A planar curve extrudes vertically to the curve plane by default. If the curve is not planar, the default extrusion direction is the z direction of the active CPlane.
• The extrusion preview direction in the viewport defines the positive direction for distance input.
• An extrusion object will be created only if the input curve is planar and the extrusion direction is vertical to the curve plane. Otherwise, a polysurface will be created.

Command-line options

Output
Creates a sphere by picking the center point and a radius point.

• Surface Create an extrusion or a surface object.
• SubD Create a SubD object.

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
Deletes (Yes) or keeps (No) the input object.

SplitAtTangents

• Yes Tangent points on the input curve extrude as joined edges.
• No Tangent points on the input curve extrude as surface kinks.

SetBasePoint
Specify a location that serves as the first point when picking two points that set the extrusion distance.
