Mechanical and Electrical Reflected Ceiling Plan (RCP) Strangeness

There is a strange behavior, when a RCP’s Discipline parameter is set to either Mechanical or Electrical, that has caused a problem for us on a couple of occasions.

Normally the view parameter Underlay Orientation is grayed out and not available when there is no Underlay selected. However, when a view (any view) is set to Mechanical or Electrical, that parameter becomes active and can be changed. This hasn’t caused a problem with floor plans yet. But I see how it could.


While it’s bad enough that a user could change this parameter to plan in a RCP (or to RCP in plan even) what makes this truly sinister is that the default for a NEW REFLECTED CEILING PLAN is PLAN for this parameter (that’s why it hasn’t caused issues for plans, it’s the default there as well.)

We have had occasions where the ceiling just no longer shows (as expected when set to plan) or in a linked model it was just showing the ceiling grid in the wrong place. Which is far worse, as we found when we went to coordinate light fixtures, air terminals and ceilings. YIKES!!!!!

So, it’s imperative that anyone who makes a new ceiling plan that is to be used for one of these disciplines needs to change that parameter to read Reflected Ceiling Plan.

To make matters more difficult, Revit has decided that this parameter is not something that you would want to set as part of a view template, even though you can set it’s Underlay (hmmmmm, that makes sense. I can’t count the times I’ve wanted to have multiple view have the same Underlay. Well only because it hasn’t happened.)


And to really confuse the user, when the same view (with the incorrect value for Underlay Orientation) is set to COORDINATION or ARCHITECTURAL for it’s Discipline… of course it displays correctly (exactly as you expected, right?) Now, don’t be silly and think that it has somehow magically changed the incorrect value. No, Revit has just decided to ignore it.'


Have I logged this as a support request? No. I probably should, but I’ve been busy fixing my own issues…
