The ExtrudeSrfAlongCrv command creates a solid by tracing the path of the surface edges along another path curve.
Notes
● | 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.
The SubCurve option extrudes a curve the distance specified by picking two points along a curve.
Note: The extruded surface starts from the beginning of the curve, not the first picked point. Picking the points only establishes the extrusion distance.
ToBoundary
Extrudes the object to a boundary surface.
