Revit's Detail Level component error of insufficient memory

[Japhy]

It’s not the Detail Level Component, that just tipped it over. The general rule is not to pass data through panels; only text, and there are limitations.

Error in Text Panel, turns to dripping red stuff

The amount of data should matter all that much (it will have a performance impact of course, but that’s not the issue here). Each item is drawn individually so only those items currently visible in the panel are considered. However if one of those items is HUGE, GDI drawing may simply choke on it. So try to not show enormous amounts of single block text in a panel.
