In this DisplayTreeViewItem first, we find all the ViewTypes from the current Revit document and create a first-level TreeViewItem. And call our DisplayTreeViewItem method too. In the Viewer Constructor, assign field value to the document which uses as an argument in our partial class constructor.

(viewItem) įirst, we create a field to store the Document instance. TreeViewItem viewTypeItem = new TreeViewItem() ViewTypenames.Add(()) įoreach (string viewTypename in viewTypenames.Distinct().OrderBy(name => name).ToList()) List elements = new FilteredElementCollector(document).OfClass(typeof(View)).ToList() SortedDictionary ViewTypeDictionary = new SortedDictionary() However, when the software has an issue that causes drawing loss, that is a problem.// viewtypename and treeviewitem dictionary Look, I try to be realistic about software challenges and you do not see me voicing many complaints at all. EDIT: Actually, I am editing this to reinforce the fact that multiple Revit online venues list this as a 2020 problem so you know what, pound sand with your comment that I should have looked first. Lastly, I did look into this and all I found was an issue with 2020, not 2019. Yes, shame on me but it is a bigger shame the software we pay thousands of dollars for cannot be trusted, even with their autosave features. Frankly, I tend to still do the ctrl-s thing but this time did not. I have autosave set up on this machine for every 10 minutes. I guess the lesson is not to ever trust the software that we continuously pay for.

My frustration is not at you but software that has an issue which is not my fault. If you had looked into this before going off on a rant you would already know that it was fixed in an update.Īlso, if you saved more often you wouldn't lose so much work.
