This is a design issue. Just as the dimensioning tool has the option to select
number of decimal places, so it would be useful to do the same for the object
dimensions displayed in the box at the bottom of the screen, whcih si fixed at 2
places regardless of dimension format. I only use metric. If displaying metres
it would be more useful to have 3 places of decimals, as this would take the
sizes to the nearest whole millimetre. (Which would probably suit all users
except engineers). Since the menu only goes to two places, I have to set the
menu option to centimetres to get to the nearest millimetre. This leads to me
make mistakes as none of my drawings or reference material is in centimetres. It
is quite common practice in drawing in metric to try and stick to one metric
format, and not mix metres, cms, and mms on the same drawing, or alter the
number of decimal places used. This is because it is easy to misunderstand
decimal places, or even have a decimal point not print clearly and be missed. By
sticking to one format for all sizes you always know where the decimal point is,
and what sizes you are dealing with, especially if m, cm, or mm is not written
every after every size. Saves space and clutter). Choice of decimal places
displayed please!
I dare say someone doing an engineering drawing would like mm to 3 or 4 or 5
decimal places, mainly for it would merely be visual confirmation of an object
size, as I doubt one's mouse could be moved to that accuracy
