Best approach for drawing temporary objects

[Anonymous]

I am writing Revit addin. Part of functionality should be also presentation of some objects (mostly model lines, but other elements would be nice) which are only for information purposes for an user and shouldn't be part of the model. There should be visible only during session, when user uses (otherwise modeless and interactive) addin. These objects shouldn't be stored when saving or synchronising model. There is no need for user to interactively manipulate (change properties) with these objects. All manipulation can be realized through addin.

Is there any suitable functionality for this available in api or should I somehow improvise with standard (appropriate tagged) DB elements?

What would be the best approach for introducing such objects to Revit?

Hi!

Thanks, something like this was my first idea, but I didn't know that it is realised in API.
