I have a project with several open web joists being used as part of the lateral framing system, as moment frames. Some of the joists are modeled as trusses in Revit, as they have a sloped top chord and it was easier to put in a truss than mess with the joist family. Now I'm trying to get the moment connection symbol to show up in plan, and I can't make it work. For the joists modeled as beams I was able to go to the family and change the symbolic representation parameter to project, but there doesn't seem to be a way to do that for trusses. I can select the individual chord memeber, but checking the moment frame box does not do anything.
