I believe this can be done this using the Brightman method of organising the model, albeit not as easily as just a ‘one click’ operation…
Keep all level tags on and then turn off all other tags except doors
Only in the current (sequential) order of nesting, so if doors are nested in levels then you would have to cohange that. It is not dynamic or easily changed, you would have to physically change the hierarchy.
The condoc system is very useful for that specific system, but I would like to switch to others, as well. The mentioned doors in a byilding is just an example that can be solved by that peculiar system.
What if I want to display appartments that are sold and costs more then 500.000? Etc.
While you could set this up, also, the need to switch quickly is becoming more important.
