I have a default setting for dimension geometry extension lies of -2.0
I have reset it to -.5, thousands of times, it seems.
How do I change it so it stays as I want it?
Are you working in a DGN file or DWG?
There are some issues regarding dimensions in DWG mode.
And there are some options dependent of your Microstation version.
If working in DGN file you should work in a DGNlib file where you store your dimensions. Unless it's a one time thing that you need only for a single drawing.
Did you save your new settings?

Yes I havent yet started storing dim styles in a dgnlib
when you say:
working in DGN file you should work in a DGNlib file,
I suppose that is the same relationship between DGN and DGNlib as
I use to manage my customised menu items.
