How to get 587.0 dim in metric

[jacek0841]

When using mm units on dwg I can not get dimension to appear 587.0 when the "real" dim is 587.0.

No problem to get 587.1 when real dim is 587.1 (mm).

I know it is possible to get dimension 587.0 on dwg but I do not know how to do it.

Thanks

Consider switching to ANSI standards instead of ISO standards--I believe this is the issue here, since the decimal place is assumed in ISO (if I remember correctly). You may also need to check your tolerance/precision settings within Tools > Options after switching standards to make sure that's set to one decimal place.

Reason trumps all. And awe transcends reason.

Under Tools->Options->Document Properties->(Dimensioning, I think) should be a setting for "trailing zeros". Depending on your dimensioning standard this may be set to zero or "Smart". Fiddling with that setting should get you what you want.

Both ASME and ISO standards say that metric dimensions do NOT use trailing zeros. If you model a part at 587.000000, then the drawing will show 587.

The "problem" originated from our dwg Title Block Notes, specifically Tolerances - Machining:

X +/- 0.75
X.X +/- 0.25
X.XX +/- 0.075

Dim 587 would be interpreted as having 0.75 tolerance, but 587.0 as having 0.25 tolerance.

Thanks for all replies.

Jeff is correct about the standards.
Since the standards say don't use trailing zeros "587.0", call out the tol at the dim "587 +/- 0.25".

Jace,

There is a common non-understanding of metric dims that confuses tolerance methods between metric and inch. In metric, the tolerances are determined by ANSI B4.3 based basic dimension, and how permissible variations is appied to International Tolerance Grade (IT). You only need to add specific tolerancing to a dim if you want to specify something other than the standard. This means that metric does not depend on decimal points to determine tolerance because it relies on the length of the dimension itself and IT specified.

I do the same thing that Jacek does. We have inch parts and metric parts and a mixture of cad and old paper drawings, and our shop people and vendors are used to looking at the title block. I just set the default to be "show trailing zeroes" then edit the display manually whenever needed. I know this violates the standards but I don't think anyone is required to follow them to the letter (well, I hope not, the police might come and get me tonight).

EngJW, that's actually what I've done in the past too.
