REVIT2018可以添加吗，有大神试过吗

Please update for a newest version of revit, thanks you. 

Really good Add-In. It would be useful if you could tab select an entire run instead of selecting each individual element you want to measure, and then maybe a way of scheduling this out so you can save the lenghts? Otherwise for a first release it does exactly what it says on the tin.

This is an excellent little add-in.

Activate add, create yout selection, finish and you get a little pop-up showing the lengths.

There is one additional that would make it much more useful: adding centre lengths from duct/pipe fittings i.e. the centre line length including fittings.
