Hi@RNDinov8r. That situation I can understand, and it can be fairly complicated to set up, because as you said, that link seems to disappear when the last drawing view of that model is deleted, because it looses the reference to the model document, and thus looses the connection to the parameter too. I don't know if I've tried that specifically before within a template like that. I have stuff in the title block that automatically updates to values in 'the model' when I place the first model view into it, but those are all 'standard' properties, not custom ones. And I have sketch symbols which contain live references to custom iProperties in the model file, but I usually always insert those after I have placed model views on the drawing. Could this note/text box be created as a sketch symbol, then inserted? I'm not 100% sure it would make the needed difference, but it might. When I go to edit one of my sketch symbol definitions (stored in separate drawing document as library), I can still see the <...> placeholders in there, containing the unquoted name of the user parameter or custom iProperty, and there are is no 'model document' present for them to point to, and no custom iProperties or user parameters in that drawing for them to point to. So this seems like a definite possibility.
The alternative, similar to what I said in the previous post, would be to maybe include a unique placeholder within that note/text box that can be found/replaced by an iLogic rule. Another idea is to create the needed parameter or property within the drawing document itself, with a default N/A type value, so that the note/text box has something persistent to point to point to. Then copy the model value over to the drawing to overwrite its value when you place a model view. Either way, some iLogic might need to be involved.
