ExtrudeCrvAlongCrv

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

Note

• 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.
• 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
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.
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

Note

• When this option is used, the output will be a polysurface.
• When UseExtrusions is on, this setting has no effect.
