Synopsis

extendCurve [-caching boolean] [-constructionHistory boolean] [-curveOnSurface boolean] [-distance linear] [-extendMethod int] [-extensionType int] [-inputPoint linear linear linear] [-join boolean] [-name string] [-nodeState int] [-object boolean] [-pointX linear] [-pointY linear] [-pointZ linear] [-range boolean] [-removeMultipleKnots boolean] [-replaceOriginal boolean] [-start int] object

extendCurve is undoable, queryable, and editable.

This command extends a curve or creates a new curve as an extension

Return value

string[] Object name and node name

In query mode, return type is based on queried flag.

Z of the point to extend to
Default: 0
-extensionType(-et) int createqueryedit
The type of extension: 0 - linear, 1 - circular, 2 - extrapolate
Default: 0
-extendMethod(-em) int createqueryedit
The method with which to extend: 0 - based on distance, 2 - to a 3D point
