Ok, that is What Revit Wants. And in fact, it doesn't allow you to have duplicate Detail Numbers,
... because that would be madness, right? Well, in some Architectural firms, they may have drafting standards which indicate something like this:
- We will reference Interior Elevations from our General Arrangement Floor Plan
- The View Tags will have letters a, b, c, d and so on for each Room
- These Interior Elevation views will be placed together on Sheets
- We will append the Room number to the Detail Number so that we can figure out which Elevation a is which...
- Meaning that there will be multiple Detail Numbers that could be the same on each Interior Elevation Sheet
I'm not so proud of this, but it is one of those hacks that just seems to work...
- Create the Viewport Title Tag with a Shared Parameter for the View Room Number, and the Detail number in one label together
- Use a special invisible character to make the Revit program think the Detail Number is different, when it appears exactly the same to human eyes... as I said this is bad Revit
This is the Unicode character U+200B: Zero Width Space.
Ok, bring on the Comments :)
