Looks like there a market for electronically sealing Cad drawings so that they can only be read and not copied.  That way, whatever is "published" can't be modified, and fine print can be added to the drawing that limits it use, say to a particular job, etc.

Unfortunately, as we all know, the advent of Cad and the proliferation of
the internet to allow us to transfer drawing files and details

When my firm first started, we were trying to be as accomodating as
possible, just trying to get work; so we would email the structural files to
the architect for them to presumably "plot out"...

Anyway, these two "friends" of mine who own an architectural firm typically
"re-used" cad structural detail sheets of mine on other "similar" projects
(and sometimes altered the details more to their liking!!!!) unknown to me.

(This was all done to avoid paying me for enginerring on the subsequent
projects, of course)

Anyway, I found out about this practice later on either during the shop
drawing phase or when they needed help and/or calculations to obtain

To say the least, I was pissed.

My office now does not send files electronically to anyone, under any

On a more positive note...the "first class" architectural firms i work for
now (thankfully) never even sneeze without consulting us...

So there are good ones out there...

  Today I became aware of a disturbing situation. It seems a contractor
(whom I do not know personally) copied a portion of a drawing produced by
our office, reassembled it into a drawing of his own and tried to pull

  Tomorrow I meet with the individual who alerted me to this situation and
will have the opportunity to see the drawing in question.

  Anyone ever have a similar experience? Anyone know of the legal recourses
available for something like this?
