The quick answer is a Model Line, on a Lines subcategory of Stucco Control joint or the like. This will track with the wall, and the ends can be locked to perpendicular walls, etc. And it can be in a Design Option while the wall is in the main model.
The more complex answer is a 2 point, wall hosted family. Now I can schedule and total the joints, as well as control it graphically, and even turn it off. But being wall hosted means I can't have the control joints in a Design Option and the wall in the main model, correct? I suspect I will need at least two or three Design options for a while, and the walls themselves will be changing while the jointing is played with, so having three copies of the entire building skin just to play with control joints won't work.
The most complex answer of course is a swept reveal, which offers niceties like breaking at a door and such, but this is a site with 8 buildings, upwards of 50 exterior doors and windows on each building, and control joints at every fenestration corner. We could be talking hundreds of reveals per building, all brought together in a single site model for presentation. Ugh! And again, no Design Options without the wall also being in the option. Correct?
So, are my Design Option assumptions correct? This seems like a bug to me, or at least a failure of Revit to "Work like architects think", and also a suggestion that Model lines are the only option until the design settles down. Anyone have any thoughts or comments? Anyone been down this road?
Thanks,
