how do I remove the commas in millimetre.

[Anonymous]

how do I remove the commas in millimetre because sometime when I take a printout it looks like dot (decimal). I do want to use Dimension Text setting Content Panel.

It is not an Archicad setting but a Windows setting.
Control Panel > Region and Language > Formats > Advanced Settings > Digit Grouping Symbol.

If you do change it you may find that existing dimensions will not change - only new dimensions you place.
Also if you share the file with other users on other machines you will need to make the same change there.

I don't particularly like the comma but have grown used to it and I don't bother changing it as we are constantly swapping machines in our office.
