Collect Views not on Sheets

[Anonymous]

What is the fastest way to generate a list of Viewplan that are not placed on sheets?

Hi!

I think the simplest and most efficient way to achieve this is to do something like this:

var parameterFilter = new ElementParameterFilter(ParameterFilterRuleFactory.CreateEqualsRule(new ElementId(BuiltInParameter.VIEW_REFERENCING_SHEET), string.Empty, false));

var filter = new LogicalAndFilter(new ElementClassFilter(typeof(ViewPlan)), parameterFilter);

col = new FilteredElementCollector(doc);

var views = col.WherePasses(filter);

@aignatovich some views that are placed on sheets does not have referencing sheet. so this will still include some views that are already on a sheet

Okay, so, find all Vieports, then create a hashset from ViewId property of each viewport, then collect all viewplans and check each view plan id not in the created hash

that might be it, still looking for other solution...but thanks

It seems, it is also quick, simple and efficient.

This is an iron python version (I use it for quick test, I'm too lazy to open visual studio, create a new solution...):

clr.ImportExtensions(System.Linq)
col = FilteredElementCollector(doc)

viewports = System.Collections.Generic.HashSet[ElementId](col.OfClass(Viewport).Select(lambda x: x.ViewId))

plans = FilteredElementCollector(doc).OfClass(ViewPlan).Where(lambda x: not(viewports.Contains(x.Id) or x.IsTemplate)).ToList[ViewPlan]()

lookup(plans)
