I was quite disappointed that I didn't see in the 25 update (still) an easier switch between metric and imperial system. We work between Europe and United States with European and Americans products with different sizing in these systems. its important to us to switch between these dimensions, and its surprised that such trivial thing is not built in the software (yet). We can't be first, working in United States and switching between the systems, no to mention this no?
Could you bit elaborate this with some pictures or screenshots? as unable to understand whether you are talking about this units change relevant with Designing, Library parts or Documenting (Dimensioning). As for few options the conversion is very easy smooth going and hassle free as per my experience.
