This is something that used to be very easy to do in autocad (with a polyline) and checking the lenght on the properties bar.

When I select multiple lines (chain of lines) the "lenght" data is greyed out.

I hate having to measure every segment separately! It has to be easier... right?

[#2]

use the Measure tool, using measure between two elements, ad check on the Chain option in the Options bar.

[#3]

Or, maybe faster, without checking Chain, is: Measure > Measure Along an Element. Hover the mouse over the first item, hit the tab key, and click. The result of the total length would be in the options bar.

[#4]

It seems that both solutions involve measuring again everytime the chain of lines are modified. Not ideal to me.

A friend suggested using a spline line with a very tight radius at the corner- it generates an overall lenght on the properties. Seems to be working. Thanks!

[#5]

Not a good advice from your friend. Splines have other issues. Have you tried to use Trim/Extend with splines? You are creating a new set of issues for not doing one extra click with the Measure tool.

Can you tell us specifically what you're trying to measure?  If it's path of travel, then I'd recommend using a line-based generic model element, and then generating a schedule that stays up-to-date with the total length.  If it's something else, there might be a better way, but it's hard to say without knowing exactly what you're doing.

[#7]

Correct: I am trying to measure a path of travel.

What you are suggesting sounds quite complex ....  Wonder whether I might as well measure every line instead.

But if not too much trouble, I am curious to hear more.

[#8]

Then the proper question to start this thread with was "How to create and measure an egress path?" instead of "How to determine the total length of multiple lines?"

[#9 · Accepted solution]

It's actually not that hard, even though it sounds a little complicated.  The method I use is shamelessly stolen from Steve Stafford's blog, where he provides the families and schedules you'll need to get the job done.

Thanks! I'll give it a try.
