Extrude Surface Along Curve

The ExtrudeSrfAlongCrv command creates a solid by tracing the path of the surface edges along another path curve.

Steps

1. Select a surface.

2. Select the path curve near the start.

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

  1.Select the path curve.

  2.Pick a start along the path curve.

  3.Pick an end along the path curve.

-ToBoundary: Extrudes the object to a boundary surface.
