I'd like to scale up a few text objects to a certain total X dimension, keeping aspect.
Selecting all allows scaling as group, but this only affects scale factor and as such does not allow an exact dimension.
Setting the X dimension for a selection only affects the active object (I was hoping to get the scale factor to use on the group's other axes).
The scale factor obtained by converting to a joined mesh and then adjusting dimension seems off by about half.
See How to scale dimensions proportionally to a specific size? for sizing a single object.
