getting bug eyed

ahhhhh....I am a slow genius then ) ...detached dwgs!
why have I misunderstood this for so long (

 

And to add to the list:

The random lines were apparently a problem with the sheet format. I
changed to another and then back and the random lines went away.

New to the list are disappearing edges on part when there is an
underlying hidden line. I had to sketch in a line manually to kludge it
into submission.
Differences in print output depending on whether it goes to the HP
plotter or the AllinOne printer/copier.
Fonts on the plotter print mysteriously changing to fixed font.
And more hidden dimensions reappearing.
Dimensions and notes moving around depending on which printer is
selected.
And from a standards point of view when a detail view is connected to
it's source circle with a line should the detail label be suppressed?
We think so because there will be no label on the source circle.
Oh, and did I mention that when plotting D size the foot notes were
shifted into the title block border but were not so shifted on B size
plots.

And of course a few more crashes including the almost repeatable crash
caused by going from drawing to assembly and back again.

 

This is list is scary shit - all in one model/drawing ?
I have come across most of the above, at different times but never in one
bomb.
That file could almost be classed as nuclear !

 

Just one drawing.

Just plotted another stack of D size prints. Again the fonts were
screwed up on a few sheets. So they will have to be plotted again.

 

To add more to the list for this one drawing:

1. The presence of a particular text block and hatching caused exported
dxf / dwg files to crash DWGeditor and hang ACAD.
