I'm using AutoCAD 2013.  I'd still consider myself a novice at Autocad, but I've been using it since 2008....just for residential floor plans.  Layout management has never really been a problem for me. I do not know what's going on today.  Apparently it's not a common problem either.  I'm hoping I'm just having a brain freeze kind of day. 
When I change the scale of my floor plan in the layout from 1/8"=1'0" to 3/32"=1'0", my doors "close." It's so strange.  The swings disappear and all the doors, and cased openings are closed. 
I changed my Ltscale to 1, thinking that was the problem, but no. 
When I change the scale back to something larger, they come back! 
I have NO clue why this is happening. 
Thanks for any help.
