Not seen how to do this in any tutorials unless I missed it, I have added some dimensions in white for clarity over my shaded mode detail view with detail inactive, so they are existing in Layout mode only.
I have then made a copy of this layout to create 1:1 plans of 2 items within it.
Scaling the detail from 1:2 to 1:1 sees the white coloured text block, leader and dims, get left behind and remain at 1:2 scale.
I group them then select edge of inactive Detail box and they vanish, I group them to it anyway, with box inactive I alter scale to to 1:1 then ungroup to see them again but they have remained placed as before.
If I activate the Detail they reappear. BUT ARE NOT SELECTABLE for grouping to it, as to be expected.
How does one scale them along with the detail view ?
