I don't edit dimension often beyond grip-edits. For those times I do edit, I have the following routines to automate 99%.
DimSE instructions
dse - Dimension Suppress Extension lines
Each pick of a dimension cycles through possible combinations
of suppressed extension lines. Use this to turn off dimension
extension lines so that underlying centerlines show.
dsa - Dimension Suppress Arrows
Each pick of a dimension cycles through possible combinations
of suppressed arrows.
dsh - Dimension Stack Horizontal toggle
Toggles stacked horizontal fractions on/off
dino- Dimension INches Only toggle
Toggles dimensions from inches only to feet and inches
dwd - Dimension Width Dynamic
Select a dimension then use the + and - keys on the numeric
keypad to dynamically decrease and increase the width factor
for the dimension text. This width factor is applied as an
mtext format in the dimension text override.
dth - Dimension Text Horizontal toggle
Toggles horizontal location of dimension text, from first
extension, to centered, to second extension.
dsro - Dimension suffix RO (Rough Opening)
Adds \XRO to the dimension suffix as a style override
dspm - Dimension Suffix Plus/Minus
Adds %%p to the dimension suffix
