Has anyone figured out how to automatically omit the "%QN" quantity if there's only one hole feature?
%QN is Smart Quantity. Like Smart Depth.
Go to the Smart Depth tab and place your codes there. Not the %QN.
Like %QC X for example.
Then in the Feature Callout fields use the %QN.
You may also find that legacy drawings do not work unless you thououghly recompute the views with Ctrl+Shift+Update All Views.
