Line length command malfunction

Rhino
1

Ok, admittedly it’s probably user error, but I have just spent 10 hours measuring lengths of various lines and entering them into a spreadsheet only to find out that something is going wrong right as I thought I was done…

I must have some overlapping lines that are now grouped together and/or joined together and so when I select it and use the _length command, I get an output but I have reason to believe that it isn’t accurate. (one side of a symmetrical shape is longer than the other).

Is there a command where I can look for overlapping lines or otherwise prevent this from happening?

Imagine you have two overlapping straight line segments that share the same endpoints… or maybe there are segments of a curve that are directly ontop of another and visually you can’t see the difference, and if they are grouped they act like one line. This would screw up the _length command. HELP!

Any input would be great.

You could try this script which will show you where the overlaps are…

Thank you for your reply! Handy script you got there.

Hi Chris - Length will tell you how many curves it has measured.
‘Cumulative length = 24.308 millimeters for 2 curves’
