This is an issue I think lots of people have but I'm struggling to understand Solidwork's approach to setting font sizes and leader lines when creating a drawing from a solidworks part or assembly.

In autocad (iirc) you could just scale up a part and the dimension font and leader lines and arrows would change size so that way the dimensions font is the same size relative to the part.

In SolidWorks it seems you can only set one font size for the entire drawing. If you want to change font sizes you have to edit the properties of each dimension you create manually. I've read about this issue and it seems to be related to actual drafting standards (ANSI ISO etc.) which seem to dictate all drawings have a specific font size/arrow size regardless of the part size.

Can someone explain what the correct approach is to dimensioning drawings in terms of font size and part scaling? For example, if you have a large assembly and a small part in the same drawing, the dimension leaders and fonts for both will be the same size so you end up with either the large part's dimension font being really tiny or the small parts dimension font being huge. Are all the dimension fonts and leaders supposed to be the same size even if the parts greatly differ in size?

Here's an example of what I'm talking about, both parts are the same scale however, because they both use the document's font size and leader line scale, the large parts dimensions look good but the small part's dimensions are overlapping and make it difficult to read.
