The ExtrudeCrv command creates a surface by tracing the path of a curve in a straight line.
Steps
Select a curve.
Command-line options
Output
Surface: Create an extrusion or a surface object
SubD: Create a SubD object.
A SubD friendly curve as the input creates a better SubD object.
Some options may not be available when Output=SubD.
Direction: Pick two points to define the extruding direction.
BothSides: Extrude towards the both sides of the input curve.
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.
ToBoundary: Extrude the object to a boundary surface.
DeleteInput: Specify if the input object will be deleted.
SplitAtTangents
Yes: Tangent points on the input curve extrude as joined edges.
No: Tangent points on the input curve extrude as surface kinks.
