Eddie and everyone else

We are moving from US units to metric units and will be changing our formats and practices accordingly. We intend to comform to ASME standards. Beyond that, we're looking at our options, and I'd like help to do this right. Here's our plan so far:

EDIT:

1. Use US sheet sizes.
2. Use US projection.
3. Use decimal point, not a comma, as shown in ASME Y14.5M-1994.
4. No trailing zeros, per ASME Y14.5M-1994 1.6.1, except to match bilateral tolerances per ASME Y14.5M-1994 2.3.1.
5. Use zero before decimal point for values of less than 1, per ASME Y14.5M-1994 1.6.1.

6. Use one angular tolerance and one linear sheet tolerance, regardless of size or decimal places.

We have been using decimal places to show sheet tolerances, such as .xx = +/-.02 and .xxx = +/-.005. Is there a better, ASME-compatable way to show sheet tolerances in a metric drawing?

Anything else to consider when moving from US to metric units?

Thanks
