Hi sos,

re:
> Thank you. I've been using Options -> General -> Decimal display, which does not affect dimensions.

That one under Options > General > Decimal display controls the program UI, like the radius field in the circle command for example.

Dimensions have their own settings separate from that. You can control the default properties that are applied to a newly drawn dimension by editing the preset properties under Options > Dimensions.

If you want to change the display properties on an already existing dimension that's done by selecting it and using the "Details..." dialog.
