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.

    • SubD friendly curves as the input create a better SubD object.

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

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

DeleteInput

  • Yes: Deletes the input objects.

  • No: Keeps 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.
