I have "Show units of dimensions" selected so I can see "mm" in the dimensions but with that selected it also shows "deg" for all angular dimensions. I don't want angular dimensions to show this. The only work arounds I can find is to set the "Override value" for the angular dimension. The only problem with that is the dimension doesn't update when modified. Or de-select the "Show units of dimensions" and then select all dimensions in the drawings and add a suffix to each dimension.
