# Extrude Curve Tapered

## <img src="/files/fLCx9K6Iz0mxqgED0277" alt="" data-size="line"> Extrude Curve Tapered <a href="#profiles" id="profiles"></a>

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 extrisopm 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) continually.

DeleteInput: Delete (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.
