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?
Solved! Go to Solution.
Solved by rosskirby. Go to Solution.
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.
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!
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.
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.
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?"
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.

Sorry. It won't work. The question is about Revit, not about AutoCAD.
@ Alfredo_Medina
There are many reasons one might need to measure the length of multiple lines or walls. Many more than just path of travel. Zoning codes reference the length of walls to determine definition of basements. They also reference percentage of existing non-conforming walls that may continue along a length of encroachment in a yard. Architect's rely on CAD to define these dimensions for approvals.
I don't make this point to correct you but to express to rosskirby that I share the frustration with Revit. Not frustrated by the learning curve, we're way beyond that. It's because the software fails miserably to meet many fundamental capabilities. I can't' return to 2D CAD, and love Revit for that, but I often find it miserable to forge ahead. There should not be Tips and Tricks and third party applications to make it perform as expected.
I don't see your point.
If you want to measure the total length of multiple lines or walls, it can be done easily as explained in message # 3 in this thread.
If you want to measure an egress path, schedule the lengths, tag it, etc, then, you need some other tools, as explained in message # 9 by Ross Kirby, which includes a link to Steve Stafford's blog, who has explained the solution in his blog for several years.
Both needs have a solution, without using any tips and tricks or third-party applications, just using the native Revit tools.
I know this is a liitle late on this reply, I am looking for an answer to totaling the length of multiple lines. I do site development and do feasiblity studies....for way too little feee, and don't want to spend the time redoing my planners less than perfect line work for "phone quote" probable costs. I need to take a subdivision street centerline and total by selecting the all. A very talented programmer....JW.... wrote a LSP for an earlier version and would have expected he pass that along in the new software. I also do preliminary layouts of teh water, saniatary sewer systems, and drainage systems and would like to total those lengths also.
Thanks in advance!
To measure total length of lines, please do as described in message # 3, above. It works on model lines, only, though; it does not work like that on detail lines.
I know this post is a little old. But one way I measure multiple lines / polylines or anything else that has a length property in AutoCAD which I would think in theory work here as well is to use MTEXT. Sounds weird I know but here is what I do:
I know this sounds like a little bit tedious but when you're finished, if and objects length gets changed, your calculation should update after you do a regen. And also please note, that if you erase an object you will have to edit the formula and erase that objects now unusable field from the formula, which can be easily done through the text editor.

You are aware that this thread is about Revit, right?
