"Some Panels in this curtain system are slightly malformed. The problem is most likely ignorable. This problem usually occurs when a panel or parts of a panel have been divided so that they are very narrow..."
An "ignorable" warning I can't actually ignore?! Hmmm, I wrote a post about this a few months ago; Warning! Revit Wish Ahead! In the post, I listed a number of things I would like to see fixed with the warning dialog. Ignoring warnings was number 1 on that list!
Please attend to the warning dialog, this is NOT an ignorable development item.
