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

Steps

  1. Select a curve.
  2. Specify a distance.

Note

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

  1. Pick a base point.
  2. 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 to Extrusion which is by default.

SubCrv

Type subcrv to select part of a curve as input.
