The ExtrudeCrvTapered command creates a surface by tracing the path of a curve in a straight line tapering in or out at a specified draft angle.

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.

DraftAngle

Specify the draft angle for the taper. The draft angle depends on the construction plane orientation. When the surface is vertical/perpendicular to the construction plane, the draft angle is zero. When the surface is parallel to the construction plane, the draft angle is 90 degrees.

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.

Corners

Specifies how corner continuity is handled.

Sharp

The corners of the tapered surfaces will extend to meet at sharp corners with position (G0) continuity.

Round

The corners of the tapered surfaces will be filled with filleted segments with tangent (G1) continuity.

Smooth

The corners of the tapered surfaces will be filled with blend segments with curvature (G2) continuity.

DeleteInput

Yes

Deletes the original geometry.

No

Retains the original geometry.

FlipAngle

Toggles the draft angle direction.

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.
