Scale of Dimensions drives me mad

As you can see here, Scale of dimensions is 1:1 Text height is 1 but I can’t neither control text height nor change anything with scale. Is this a bug? Thanks for your help on this!

Hi Hannes - is the actual dimension object in model space or a layout? If it’s in a layout then set the text height as you like for layouts - then set the scale, if any, that makes sense if you want to use the same dim style in model space.
