Computes the length of the specified line as the sum of the distances between the points making up the line.
length()@<Location>
where:
<Location>is any 1D location. Specifying a 2D location will not produce an error; the sum of the edge lengths from the elements in the locator will be returned.
length()@Polyline1 returns the length
of the polyline.
>calculate length, <Location>
Note: While using this function in Power Syntax, the leading character is capitalized to avoid confusion with the Perl internal command "length".
