Re: Any way to protect drawings released to other companies

It is acceptable to send actual CAD data to others.  But you must
designate a control source in case someone edits the CAD data to
sup****t their needs.  A good control source is a PDF do***ent as it is
cannot be changed.  You will need to do***ent your process.  I
designate my engineering deliverable as the PDF file.  I also send CAD
data to them so they can use it in their designs or whatever.  I also
add custom properties to the PDF file designating release dates and
other info.  Case in point; One customer decided to override this
concept by converting the data via AI, manipulating and turning it
back into a PDF.  Of course the resulting PDF file was missing these
custom properties.  We caught this quickly.  iQ
