Arch length dimension for intersection of curved wall and straight wall by wall core not wall centerline

[lshannonEQEBT]

Hello all,

I'm having an interesting issue. I have a curved wall intersecting with joined straight walls. I want to dimension the arc length on the curved wall, but to the center of core and not the wall center line, but the center of cores do not extend and intersect between the walls (wall center lines in blue, center of cores in green):

I have found a gross work around with disallowing both wall joins, extending the walls to the finish face of each, dimensioning the arc length, and then allowing the joins for the curved wall (if you allow the straight walls it breaks the dimension because the center of core line moves back to it's original spot):

However, I worry that something may break in the future if any walls move slightly and really don't want my team to have to go through the entire project modifying every single wall join. Also, I would prefer if we didn't need to draw detail lines on all wall joins to make this work as a different work around. Is there a different method that I am missing?

Any ideas would be helpful!

Maybe you can get there with Parts.

This is an interesting idea. I gave it a try and it still didn't work unfortunately. The walls are perpendicular to each other which is the issue I think. Revit using the wall centerline to join the walls, so the center of core line doesn't extend, it stops at the same point as where the center lines join. if the walls were flipped, causing the center of core lines to intersect, then it works, but when the center of core is on the outside of the center line join, then they don't extend to intersect. If that makes sense.

Nope. Can you post something I can wrap my brain around? Like an RVT?

Sure thing. I copied one of the conditions and made a separate model that you can look at. I also added the current work arounds that I can think of to show what I'm wanting to do. Thanks again @barthbradley!

I would place and dimension walls along and perpendicular to an arc path (e.g. arc wall) as shown below - by aligning walls to grid lines that originate from arc center.  BTW: your walls are not perpendicular to arc wall.
