Interface

For details on using the caddy controls, see The Caddy Interface.

Segments: Specifies the number of polygons into which each extruded side is subdivided. This setting also applies to manually extruded polygons.
Taper Amount: Sets the extent to which the extrusion becomes smaller or larger along its length. Negative settings taper the extrusion smaller; positive settings taper it larger.
Taper Curve: Sets the rate at which the tapering proceeds. Lower settings result in a more gradual taper; large settings result in a more abrupt taper.

Taper Curve affects the thickness of the extrusion between its endpoints, but not the size of the ends.
Twist: Applies a twist along the length of the extrusion.

When using this option, increasing the number of segments will improve the smoothness of the extrusion.
Align: Aligns the extrusion with the face normal, which, in most cases, makes it perpendicular to the extruded polygon(s). When turned off (the default), the extrusion is oriented the same as the spline.

With Align To Face Normal, the extrusion does not follow the original orientation of the spline (1); it’s reoriented to match the face normals (2), or averaged normals for contiguous selections. The Rotation option is available only when Align To Face Normal is on.
Rotation: Sets the rotation of the extrusion. Available only when Align To Face Normal is on. Default=0. Range=-360 to 360.
Pick Spline: Click this button and then select a spline along which to extrude in the viewport. The spline object's name then appears on the button.

If you open this caddy after performing a manual Extrude Along Spline, the name of the spline you used appears on the button.

OK: Applies the settings to the current selection and closes the caddy.
Apply and Continue: Applies the settings to the current selection, retaining them for the preview if you then change the selection.
Cancel: Closes the caddy without applying the settings to the current selection. Does not reverse previous uses of Apply.
