Remove trailing zeros in TechDraw dimensions

[SIXe]

How to remove trailing zeros in TechDraw dimensions? That would lead to cleaner and more readable drawings. Searching the forum I came about the thread Dimension Decimal Places, which suggests to use the format %.g, but that doesn't seem to do the trick.

Check your Preferences. If you have "Use Global Decimals" ticked, the system-wide setting overrides the FormatSpec on an individual Dimension.

That's it. %.g works now. Thanks a lot. One question, though: How to specify the default FormatSpec so I don't have to change the FormatSpec every single time?

That is crossed off on the TODO list, but was never implemented.

Will fix that next batch of changes.

Would that mean you want to implement an kind of remove automatic trailing zeros? And what to do with round of values?

13.60 = 13.6
and 5.8985 = 5.90 = 5.9

Great. Thanks.

No, just a way to specify that you want to use "%.g" instead of "%.[AlternateDecimals]f" as your default value for FormatSpec.

IIRC, "%.g" just removes trailing zeroes, so
13.60 would be 13.6
5.8985 would be 5.8985

An option to specify a *default* FormatSpec. So the user can choose to display a fixed number, remove trailing zeros or any other supported format spec.

And what to do with round of values?

That's up to the used FormatSpec. Rounding has nothing to do with this question/feature as far as I understand.

Rounding is a thing with the g formatter:

Code: Select all

>>> '%.2g' % (23.12345)
'23'
>>> '%.3g' % (23.12345)
'23.1'
>>> '%.4g' % (23.12345)
'23.12'
>>> '%.5g' % (23.12345)
'23.123'
>>> '%.5g' % (233.12345)
'233.12'
>>> '%.5g' % (233.999)
'234'

the number gives the precision in decimals shown totally.
Just be aware, that larger numbers are shown in exponent representation:

Code: Select all

>>> '%.5g' % 123456.234
'1.2346e+05'

Should be fixed by git commit 3370d0902a. Second Tab in Preferences.
