this could help I think....

you can go to a view and delete them. Problem is that something MAY be hosted on them even though there is no plan associated with them. Deleting the Level would also delete thse hosted objects. Revit will warn you upon deletion that you are removing other objects, so you could try it....

thanks, I was able to delete most of them. There are datum levels named 1st Floor and 1ST FLOOR that both have hosted views so those I'll have to deal with differently

You could create a (Shared) Parameter for visibility and use filters in your View Templates to only show the ones you want.

I've never used a filter. Can I get some direction? The shared parameter would be instance and yes/no I would guess and it would be made into a project parameter under the category Levels. Then in the Filters dialog I'm a bit lost.

I am sure you have used Filters, but you have forgotten.

I don't think you need a "shared" parameter. Why? Create a new parameter in the project by Manage > Project parameters > add > , name it, for example, "Comments" (instance, text), applies to: Levels (in this example). Done. Then go to your project, select all the elements of that category that you don't want to see, and from the properties window, enter something in the "Comments" parameter, such as "don't need". Then go to View > Filters > Add button > name the new filter, such as "don't need stuff"; on the list of categories, apply to: Levels (in this case). On the right pane, from Filter by, select your "Comments" parameter. Equals: "don't need". Close the Filter dialog. Now, go to VG > Filters, Add > "don't need stuff" > Visibility = OFF. Close VG. All the unnecessary stuff is off. Later on, you can add this filter to your View templates, by using the "VG Overrides Filter > Edit..." button of the View Template Settings dialog box, and then apply the updated view templates to your views.

I can't get away with anything around here Thanks Alf, I'll put that together after regeneration tomorrow!

Ok, you're right. Strictly speaking you don't need it to be shared. BUT: I would recommend it to be, just to be able to re-use it in different projects. Unless I'm mistaking, Dave hasn't come around to creating a Template yet in which this could very easily be incorporated (yes, we will keep bugging you about this ), so he'll need to set this up every project. Having it shared means that you can repick it every time without having to remember on a projectbase what you called it the last time.

Just my 2ct.

you're confusing me with dzatto. Dan doesn't have a template. I've had one for sometime. Granted it's a work in progress and has a lot that is not setup in it yet but a template it is. It even has my View Templates in it. I just haven't had the opportunity to use Filters very much yet and plan to do some investigating this weekend about how they work. Thanks for the help :beer:
