Elements from linked document

[AnatolyCEL]

Hello,

When I use collector constructor "public FilteredElementCollector(Document document, ElementId viewId)", I get elements visible in this view and it works fine for elements from host document. How about linked document? How can I get know if element from linked document visible in a view in host document? If I put linked document to the collector constructor, then viewId used for view from linked document as well, but I need linked document and view from host document. Elements from linked document can be hidden manually in a view in host document different ways and I need to know if these elements are visible in this view.

Thanks,

Anatoly.

Dear, unfortunately, there is no way to accomplish what you want,
and a wish was logged in our system about it before in this April: CF-2671 API ability to get visibilty or pass filter test for linked elements

A workaround may be using CustomExpoter, see examples here:
http://thebuildingcoder.typepad.com/blog/2013/07/graphics-pipeline-custom-exporter.html

when you call CustomExporter.Export, it will go through all the visible elements in the view you specified.

Hi AnatolyCEL,

sorry, it has not yet been fixed. I'm afraid it might not be included in Revit 2017

Hi,

It can be done (even back in 2015), you just have to build a function around it depending you're needs.

Search the Forum, has been asked and solved a couple of times
