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?
