Viewport Types referenced by Schedules?

[bwinterscheidt]

I have a few rogue Viewport Types that cannot be purged, even when no views are placed on sheets, so not truly "used" but still referenced somewhere in the database.  I am trying to figure out exactly how they are referenced, and perhaps then change the reference to another type that I do want to keep, so these others can be purged.

I have been able to locate the offending Viewport Type definitions (Autodesk.Revit.DB.ElementType), go back to the model, and Select by Element ID.  Manually deleting these Viewport Types takes a large number of my *Schedules* (Autodesk.Revit.DB.ViewSchedule) with them, so I figure that the offending reference must be buried there somewhere.

But, the Autodesk.Revit.DB.ViewSchedule does not seem to have any properties/methods that reference these Viewport Types.

For comparison, when non-schedule views are placed on a sheet, an Autodesk.Revit.DB.Viewport is created, whose GetTypeId() method *will* return the Autodesk.Revit.DB.ElementType ID of the Viewport Type definition.

However, no Autodesk.Revit.DB.Viewport is created for schedule views; only an Autodesk.Revit.DB.ScheduleSheetInstance (and my issue persists with or without ScheduleSheetInstances in the model).

I seem to have quickly hit a dead end, and am unsure where to look from here.  Any thoughts?

Perhaps the API doesn't expose what I am trying to find?

Dear bwinterscheidt,

I can indeed well imagine that the API does not provide much heklp on nthis issue. You could take a look at the object relationship analyser:

http://thebuildingcoder.typepad.com/blog/2010/03/object-relationships.html

Here are some examples of using it and the underlying technique:

http://thebuildingcoder.typepad.com/blog/2012/10/the-temporary-transaction-trick-for-gross-slab-data...

That might prove a useful tool to support your analysis. More than that, I really don't know. Sounds as if you have done a good job exploring already.

Good luck!

Cheers,

Did you ever find a solution for changing the Viewport Type associated with a schedule? I have 20 schedules that I will need to recreate if not. Ugg

[elina.hyvamaki]

Has anyone found a solution to this?

[Mustafa.Salaheldin]

Provide a sample RVT project please.

[elina.hyvamaki]

Thanks for replying! I can't make a sample file at the moment, because I'm not at the office, and only have access to Revit 2016 in viewer mode. But this can be tested with any schedule: is it possible to change the Viewport Type associated with a schedule?

Ok if I'm getting you right then this code shall help:

I also prefer to have a sample RVT file to be ableto reproduce the error.

Have you find a solution for the connection between Viewport Type and Schedule? I have the same problem now... Will be really appreciated if you could share any suggestion.

Thanks,

Yueying

[Mustafa.Salaheldin]

Have you tried my solution?

If you can supply a sample RVT file this will also help.

[ycui]

Hi Mustafa.Salaheldin,

Thanks for the quick response. Could you please test the attached RVT?

If I delete the "No Title Copy1" Viewport type, it will delete my "FURNITURE SCHEDULE - A" schedule from my project. So I think there are some hidden connection between schedule and viewport type in Revit. If you can provide a way to change the schedule's "viewport type" to "Section 1", it also works for me.

Thanks so much for your help. Looking forward to your result.

Thanks,

Yueying
