Company wants to use Inch drawing formats, B,C,D and E for parts designed in Metric 3

[jeff97070]

I have been asked to make some drawing formats.

Here is where I need you opinion. Our last machine we made took 8 years from design to manufacture and all of the parts were in metric and we used metric drawing formats A0, A1, A2 and A3 and everything worked fine.

Now the new project the parts are being designed in metric. But I was just asked or told to make inch Drawing formats in B, C, D and E but to have all the information in the title block to callout metric everything.

I repeated the fact to them you have metric drawing formats and this manager said were buying a large format printer and they want these inch formats made.

Is there an ASME standard out there that says this is WRONG violates the standard? If I can get this information I would like to present this to them.

Thank you,
J.S.

dgallup,
It is possible.
Some national standards require to fold parallel to short side of titleblock first regardless of actual sheet orientation which may result in creating odd edges (see picture).
Inch paper sizes are not without a sin either.
As you have noticed, no-one cares anymore. :-(

To answer your question we don not store any paper copies everything is kept in our cad tool Database. We print out 11 x 17 prints to look at and make notes on to pass around and most of the sharing is done using PDF files using BlueBeam and email these.

We send the vendor a pdf of the the drawing and the cad model which has been the SOP for many years and just all of a sudden one log term Eng has gone strange, oh well life will go on.

Again I appreciate everyone's input.

Jeff - a few more questions to be answered. How do you store your prints? Do you store them in cabinets designed for American print sizes? How do you store your "A" size prints? Cabinets for Metric print sizes?
Are you sending American print sizes overseas? Most likely people in the rest of the world will have cabinets to store "A" size prints. Also their copying machines most likely will have no way to adjust to American sizes since American paper sizes are not used in most of the world. I have gone thru a massive transfer program and the worst mistake we made (in the beginning) was to try to convert print sizes to our size. Turned out to be a big headache.
