I don't know if it started when we switched from SW2013 to SW2015 or if someone has modified the drawing templates but lately I have been really annoyed by the hole callouts.
We use dual dimensions. It is not perfect but most of the time we get what we want to show. If we ust use the smart dimension tool and add the tolerance the displaying of the value is fine.
When we use the hole callout it gets strange. The imperial and metric get mixed and it can be confusing to read with imperial value, metric value, imperial tolerance, metric tolerance.
I can't find how to display an hole callout the same way as a smart dimension with imperial value, imperial tolerance, metric value, metric tolerance.
