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.

Note

Command-line options

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.

DeleteInput

Yes

Deletes the original geometry.

No

Retains the original geometry.

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.

Subcurve steps

  1. Select the path curve.
  2. Pick a start along the path curve.
  3. Pick an end along the path curve.

SplitAtTangents

Yes

Creates a single surface.

No

Creates a polysurface when the input curves are joined tangent curves. Faces in the resulting polysurface correspond to the tangent sub-curves in the input curves.
