Possible Glitch in the Beam System ONLY when it's Sloped in Revit Structures 2011-2013

Hi everybody!
(hi Dr. Nick)

I just wanted to post about a possible glitch in Revit Structures that I've noticed from version 2011-2013 (at least), and it has to do with the Beam System. I started to notice that when I had the Beam System on a slope, my beams would start to move and not line up with the systems adjacent to it. Since then I've done some tests and isolated the problem to the pink boundary box in edit mode along the Beam Direction dimension specifically; it seems that every time I open the edit function and close it (without editing anything) this dimension will shrink by fractions of an inch causing the beams to shift. As stated in the title this only happens when the system is sloped and not horizontal, I've tried both taking a horizontal system and rotating it and also modeling the system sloped and that doesn't seem to make a difference.

I've searched the internet about this and haven't found anyone else having this problem, so I might be missing something, but if anyone else can duplicate this, then we might have a glitch on our hands.

Best,

Mark

Mark,

I have tried to reproduce this issue in Revit 2013 OOTB template and I am unable to get it to happen. First question would be does it happen to you with the OOTB template? What are your settings for the beam system?

Brain,

Thanks for looking into this, and to answer your first question, yes, I just open a new project (OOTB) and draw a beam system (sloped of course), which defaults to fixed distance, but it doesn't seem to matter which Layout Rule I use the Boundary box shrinks every time I open and close Edit Boundary mode. To highlight the issue I put a dimension on the beam direction length and open and close the Boundary edit multiple times and watch the dimension shrink. I have done this on a few systems in the office and one other location and I have been able to reproduce the problem every time.

Man I believe you are having the issue I just can't reproduce it. I have sloped the beam system via a workplane, nested in a bay, still can't get the beams to move. How are you defining the direction?

I just tried a beam system via a sloped work plane of a wall as apposed to a reference plane and I still noticed the dimension shrink along the Beam Direction length. As for how I'm defining my beam direction, I'm simply choosing a line along the perimeter of the boundary as the beam direction, is there another way to define the beam direction?
