is it - and how is it - possible to set a certain style of dimensions / arrows / annotations as default in Rhino for Mac? Every time I open a new file I have to reset these values from 1mm to the ones needed, quite annoying…
There is a style called “Standard”, if I try to make new templates they are only available in the current model.
I’m probably not quite understanding the problem you are reporting here. What template file are you using? You should be able to create a new file with the settings you want and navigate to File > Save as Template….
