Font for dimensions is Tahoma 6pt (current). It is always avalaible in the new system. I have try to change it into Arial, but the result is the same: arrows are bigger then before. Normal text have no changes.
I tested SU 2014 last year, but especialy Layout2014 was not stable on my computer, also the most new features are more interesting for architecture drawings. After every crash I had to remake my personal settings, this wa very troublesome bacause there is no feature to save this settings.
I have try it now again, but it shows the same: If I refresh an layout file the arrow size changed.
