The ExtrudeSrfAlongCrv command creates a solid by tracing the path of the surface edges along another path curve.

Steps

Select a surface.
Select the path curve near the start.

A planar surface extrudes vertically to the surface plane by default. If the surface 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
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 Select the path curve. Pick a start along the path curve. Pick an end along the path curve.
ToBoundary	Extrudes the object to a boundary surface.
