Now that I've retired?

Ive moved to a bungalow and am in the process of building a workshop using 2018 for my drawings, but I have no office atm and have my computer desplay on my tv 3mtrs away and am finding the resolution somewhat to small for my tired eyes, how can i increase the size of sketchup without changing my desktop resolution?

Shuffle your chair forward.

You can make the tool icons larger Window/Preferences/Workspace tick the box for ‘Use larger tool buttons’.
You could change some colours for things in Window/Preferences/Accessibility,
I think that’s about it without changing your screen resolution.
