You can reach anything you can see. You can build anywhere you can see.

How do i edit the settings so i can reach crates and make changes to my base in map view?

in mod settings when you create map or in mod settings while you play the map
Since 0.16 it is no longer possible to interact with the objects from the map (source: https://forums.factorio.com/viewtopic.php?f=34&t=55827)
I think it would be worth to update the mod's description.
