"Do it with a parameter"? You must be one of the Autodesk Help text editors. It irks me some to read a help response where the answer can only lead to another question and not a solution. If you have posted in the past, provide a link to that post or at least the title of the post so we can benefit from your largess. Autodesk Help is full of instances where you search for a command or tool and the documentation tells you "It is on the ribbon", well if I knew where on the ribbon the tool was located, I wouldn't be looking for it in Help. I find these vague replies to be frustrating and pointless, if one wants to take the time to reply to a post, one should offer actual advice or at least some direction less vague than "do a search".
After doing "a search" I found this and a few other posts that basically tell me I have to create a new family of doors for existing that shows the swing angle at 45 degrees or 50%. "Doing it" with a parameter also means customizing the OOTB elements for what should be one of the most basic display options in all of drafting. 50% open doors have been drawn to show existing doors as far back as I can recall and are referenced as the standard almost universally, so why would they not be that way OOTB?
Well I am off to learn how to do it with parameters. I really like Revit and I recognize that it is a complex program, but seriously some of this stuff should not be this hard.
Yes disapointing answer. A link would be nice. I am looking for a response to the same questing and I've ended up finding your very unhelpful response. If you want to help then do so. Your reply did not help me or anyone else who has this issue!
I used to have a write up on this - but what i found is a revit file with the 2d info in it that you can bring into your family file. Give it a try.
