I change the units in tools, options, document properties but then whenever I start a new sketch or drawing they've reverted to .....usually metric.
Where to I set them globally so they will stay the same?
After changing the units, you need to save the document as a template. (asmdot, prtdot or drwdot)
as Kelvin said just be sure that u have been clicked on "OK" botten befor leaving that
If you are still seeing the problem after saving as a template, make sure the Default Templates & File Locations point to the correct locations.
