Tracy sent me this DXf file but my version of ACAD 11 will not accept it.
Can anybody load this into their CAD program and convert it to a gif or jpg?
This, I assume, has all the hole dimensions for the redrive plate.

Hi Paul:
        I imported it into VectorsWorks and exported it as a R11 .dxf. Let me
know if you have any  problems opening it.

Regards,
James

   Redrive_Plate_-_R11.dxfName: Redrive_Plate_-_R11.dxf
                          Type: Plain Text (text/plain)

I got an error message "Unknown group 147 on line 1130".

Too bad DXF's are not really standardized. How did this happen? :-)

HA!   Sometime when you've got a week of spare time I'll tell you about
being an IGES Finite Element Modeling subcommittee member and then
chairman back in the '80s. Remeber, kiddies, all the computers were
coal-fired steam powered in those days.   ;-)

    Doing standards is VERY difficult work, and graphic exchange has
a lot of interoperability issues that could have never been imagined until
they came up - often due to deep-seated, fundamental issues of how
various CAD systems live and work and store info.   One final issue is
that standards organizations take whoever shows up and while 75-90%
are competent and dedicated folks, the rest can cause a lot of lost time
and running in circles.  Amazingly, IGES is still a pretty reliable way
to move models from one CAD system to the next, I still use it occasionally.
     I guarantee that the poeple that created it assumed
it would be bypassed in five years or less.  I also worked some on the
birthing of PDES which became STEP.   Exchanging graphic computer
data is WAY, WAY harder than it seems if you are not going from a single
CAD type to only a single receiving CAD type.

I can do ACAD conversions but the best graphic output is a Windows metafile,
which of course causes Paul to break out in hives, plus Linux probably
won't touch it.
