Synopsis

offsetCurveOnSurface [-checkPoints] [-connectBreaks int] [-constructionHistory boolean] [-cutLoop boolean] [-distance linear] [-name string] [-object boolean] [-range boolean] [-stitch boolean] [-subdivisionDensity int] [-tolerance linear] [curve]

offsetCurveOnSurface is undoable, queryable, and editable.

The offsetCurveOnSurface command offsets a curve on surface resulting in another curve on surface. The connecting type for breaks in offsets is off (no connection), circular (connect with an arc) or linear (connect linearly resulting in a sharp corner). If loop cutting is on then any loops in the offset curves are trimmed away and a sharp corner is created at each intersection. The subdivisionDensity flag is the maximum number of times the offset object can be subdivided (i.e. calculate the offset until the offset comes within tolerance or the iteration reaches this maximum.) The checkPoints flag sets the number of points per span at which the distance of the offset curve from the original curve is determined. The tolerance flag determines how accurately the offset curve should satisfy the required offset distance. A satisfactory offset curve is one for which all of the checkpoints are within the given tolerance of the required offset.

Return value

string[] Object name and node name

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