Extrude Curve Along Curve

The ExtrudeCrvAlongCrv command creates a surface by tracing the path of a curve along another path curve.

Steps

1. Select a curve.

2. Select the path curve.

Command-line options

Output

• Surface: Create a surface object.

• SubD: Create a SubD object.

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

DeleteInput: Deletes (Yes) or keeps (No) the input objects.

SubCurve: Extrudes a curve the distance specified by picking two points along a curve. The extruded surface starts from the beginning of the curve, not the first picked point. Picking the points only establishes the extrusion distance.

Steps

1. Select the path curve.

2. Pick a start along the path curve.

3. Pick an end along the path curve.

SplitAtTangents

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

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