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.

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

  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 objects are filled with planar surfaces and joined to maje 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).

DeleteInput: Deletes (Yes) or keeps (No) the input objects.

FlipAngle: Toggles the draft angle direction.

SplitAtTangents

  • Yes: Tangent points on the input curve extrude as joined edges.

  • No: Tangent points on the input curve extrude as surface kinks.
