Further to earv's question last week about XREF stamping of drawings, I offer the following code that I have been using.
This code has been cut down from a program I wrote in 1998 which stamped
the drawing with the user name, time and date, file name and AutoCAD
version.
Being a cut down program, the code is a bit clumsy and probably contains
elements that are not really required - But it works for me!
The program is manual in that you have to remember to type in 'stampx' to
stamp the drawing with all the XREFs. All you have to do next is point to
the top left hand corner of the drawing frame. (The program looks for the
end of the line.)
Users may like to customise the xloc and ftl to suit their own drawing
frame. Also the font iso3098b could be changed to the user preferred font.
Users should note the warning on the bottom of the program. Because the
drawing places text on the stamps layer, this layer is erased when the
program is run - Actually, only text with the style 'stamps' on the
'stamps' layer is erased, so the program is reasonably safe.
I am sure there are better ways of doing this (eg with attributes etc), but
I have been using this method for years with no problems.
BY THE WAY - I would be interested in knowing if there is a similar way of
stamping a drawing with IMAGE files attached to the drawing! I can't see
how to do it.
