Measure Length of Polyline

Good Day,

I am trying to shatter a curve at (Length=54000mm). When i check back the length in “Length” command, it becomes shorter. Any idea why?

Curve parameter is unrelated to length.
Use [Evaluate length] with normalized (0-1) length to obtain the parameter “t”.

Or you can use directly your length with normalized=false…
