First time poster... I've tried searching for this particular topic previously, but I've yet to find a satisfactory answer.
Since I started using MEP versions of AutoCAD a couple years ago, it seems that every drawing I work on eventually has something funny happen with the MEP connections. It doesn't sem to matter if it's piping, ductwork or plumbing schematics, eventually I seem to come across a "breaking point" at which the program decides to sever huge chunks of connections in the drawing. I now have a large underground plumbing drawing in which every single fitting suddenly became disconnected without any apparent reason. Like I said, I've run into this with piping and ductwork before too, but I'm getting really fed up with it now. Is there any way to fix this?
It appears that your fittings are at a different elevation than your piping. I was able to move the fittings and reconnect, and everything seems fine.
Hmm.. spot-checked the drawing again and that's not what I found (everything I checked was at 2"). Is it possible that something specific to my machine might be causing this? I just had a similar thing happen on yet another drawing. Everything was going fine and then suddenly *poof!* everything stopped connecting correctly on some lines.
