The ExtrudeCrv command creates a surface by tracing the path of a curve in a straight line.

If the curve is not planar, then it will be extruded in the z direction of the active viewport's construction plane. If the curve is planar, it will be extruded in the normal direction of the plane of the curve.
The extrusion preview direction in the viewport defines the positive direction for distance input.
Unlike Lofts and Sweeps, the initial orientation of the profile curve or surface is maintained through the extrusion.
If the input is a non-planar polycurve or a planar polycurve where the extrusion direction is not normal to the curve plane, the result will be a polysurface rather than an extrusion object.

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.
BothSides	Draws the object on both sides of the start point, creating the object twice as long as you indicate. The BothSides option demonstrated with the Line command.
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	Extrudes the object to a boundary surface.
DeleteInput	Yes Deletes the original geometry. No Retains the original geometry.
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). Note: This option is not available when the UseExtrusions command is set Extrusion which is by default. Wikipedia: Tangent
