Parameters

Parameter

Description

obj

An existing object along which the position is calculated. The object may be a line, an arc, a conic or a spline.

scalar

A numerical value which represents the parameter along the curve where the position is calculated. The parameter range along the curve is specified between 0 to 1, where 0 is the beginning of the curve and 1 is the end of the curve.
