The ExtrudeCrvTapered command creates a surface by tracing the path of a curve in a straight line tapering in or out at a specified draft angle.

Steps

Select a curve.
Specify a distance.

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
SetBasePoint	Specify a location that serves as the first point when picking two points that set the extrusion distance.
Direction	Two points establish the direction angle. Direction steps Pick a base point. Pick a second point that establishes the direction angle.
DraftAngle	Specify the draft angle for the taper. The draft angle depends on the construction plane orientation. When the surface is vertical/perpendicular to the construction plane, the draft angle is zero. When the surface is parallel to the construction plane, the draft angle is 90 degrees.
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.
Corners	Specifies how corner continuity is handled. Sharp The corners of the tapered surfaces will extend to meet at sharp corners with position (G0) continuity. Round The corners of the tapered surfaces will be filled with filleted segments with tangent (G1) continuity. Smooth The corners of the tapered surfaces will be filled with blend segments with curvature (G2) continuity.
DeleteInput	Yes Deletes the original geometry. No Retains the original geometry.
FlipAngle	Toggles the draft angle direction.
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. Original polycurve (left), SplitAtTangents=No (center), SplitAtTangents=Yes (right). Wikipedia: Tangent
