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

Steps

Select a curve.
Select the path curve.

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.

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 make a closed polysurface.

DeleteInput

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

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

Select the path curve.
Pick a start along the path curve.
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.
