How to create a full diameter dimension with two arrows?

A - answer When I dimension the diameter of an arbitrarily large circle, I only get a "half" dimension with 1 arrow, like the radius dimension. Where can I set this change?

Diameter dimensions inside a circle look like radius dimensions by default. Either put the dimension text outside (outside the circle/arc being dimensioned), or use a linear dimension DIMALIGNED with quadrant osnaps.

However, you can use the DIMATFIT variable (e.g. =1) to force both arrows to be displayed. Perform a subsequent change using DIMOVERRIDE, or preset this style using Dimension Style > Customize > Alignment Options > Text and Arrows (or Text always between extension lines).
