Big DITTO!

Good points.

Doug,

I work in product design and development, and often am amazed at the
amount of "industrial espionnage" that can be done from VRML and CAD
models/ drawings which are 'freely' available(catalogs/ websites/
photos).

I generally advise that in a competitive industry it is bad practice
to "put it all out there". Some will say, "hey, it's time for a
truly 'open' world. Sure. How many of us buy Taiwan "ripoffs" of
American or European tools? There will always be someone who will let
you do their work "for them". The Defense and automotive industry
have known this for years.

I agree with your post and points. Just wanted to point out that
sometimes the drawings are "messed up" for a reason...

Hope this helps.

P.S. If I am asking you to make a part for me, I NEED to do my best
to give you what you need. But,...
I have often tried REALLY hard to give a shop what they wanted. Many
have had similar experiences (as you have) and WON'T work with me to
HELP them! And me, since the easier it is for you, the better it 'can
be' for me...
