Travel Distance and Egress Path Options in Revit

I really don't like using Revit in non-standard ways due to the issues caused for other disciplines and  downstream workflows like clash detection, energy modeling, lighting analysis, Enscape, Revizto, VR/AR, etc. But, sometimes the path-of-least-resistance is to do so... today's post talks about using a special railing type to define the egress path, both graphically and for total length, in a Revit project.

The image above shows an example of the new Revit 2020 Path of Travel tool, which is too limiting to properly represent the code-required path of travel (fingers crossed for improvements to this v1 feature in the near future).

Also in the image above, notice the graphically appealing egress path, with right angles, which is defined using a Revit railing element. Over on the Revit Forum you can download the set of railing types shown in the image below. thanks to cftrevizohttps://www.revitforum.org/architecture-family-creation/39395-travel-distance-line.html


The great thing about using railings is they can easily be adjusted, as shown in the next iamge. Plus, they can be tagged.


They can also be scheduled... for total length and even travel time (like the new Revit 2020 feature) using a calculated value (where I think my formula is correct:)).


These railings do have to be filtered out of all views except the code plans. This can be done with View Templates or a secondary design option.
