Whenever I am drawing and connecting my ducts, I have to constantly check what elevatoin different ducts were drawn at. I find that when you copy (ctrl+c) the offset value from the toolbar (or whatever its called) and paste (ctrl+v) into the same box on the toolbar, it changes the value to something seemingly random. For examply I use ctrl+c to copy the offset of a duct at 11'-5 109/256" and when I paste it into the box, it reads correctly but then immediately changes to 20'-6".
I do know that I can paste into the properties offset box and that'll work, I just wanted to throw this out there. I couldn't find a post on it, and it's cearly a mistake that should be fixed. Although it could be a problem isolated to just the computers in my office.
You're not alone...I get the same behaviour. I just work around it by copy/pasting thru the properties palette.
I've ran into that too, but that is a different issue than what I am talking about. When I paste the offset value into the box, it will read the value I copied, but as soon as I move my cursor out of the box, it changes the value to something else.
My project units are set to 1/256", and its adding almost 10' to the value I want, so it couldn't be anything with the units. Plus, if I type in the exact same value as I pasted, it allows it. I think it's just a Revit problem, I wonder if Autodesk is aware of it. I just wanna know how Revit can differentiate between values typed into the box and values pasted into the box.
I finally solved this one... sort of (can't believe it's already almost been 3 years since this first post) I had begun a habit of pasting all values into properties and when a newer user in my office brought this strange behavior up to me I noticed something I never caught before. When pasting a value into the offset box in the toolbar (not the properties window) what happens is only so many values are pasted, the last few are cut off. So copying a value of 10' 9 51/256" gets pasted as 10' 9 51/25; the last 2 values do come in. Revit then converts the fraction of 51/25 and then entire value gets changed to 10' 11 5/128".
Now for the matter of why Revit doesn't register these last 2 values when pasting into the toolbar box...
We can avoid the issue by only using the properties window, as RAMasterson suggests, just wanted to share what I've found. Maybe it'll be fixed in 2019, eh?
I too have found that limit in the number of characters. When I come across a limitation and there is another way to do what I want, I do what works.
