Is there a way of setting the option one arrow / open leader option for diameter and arc dimensions as a default, to save me having to change it each time I dimension?
You mean, like setting it all in your drafting standard in there:
There is a method, as Wojciech Paterski briefly mentioned:
You need to 'un-tick' (Display with Solid Leader) box in the Document Properties Tab for Diameter, Radius and Hole Callout dimensions.
If you're too lazy to do this manually, I've created a macro that will do it for you much quicker.
Also bonus, if you have already dimension all drawing with the Solid Leaders, my macro will change each individual dimension to Open Leader.
Please, let me know if it works fine for you and give me a correct answer.
Macro available for downloading here.
