When you terraformed your base with beacons and created some buildings it becomes impossibe to use terraform beacons. And incomes the time of brilliant terraforming. So there are a lot of problems
1) Unable to terraform on large vertical drop.
2) Impossible to terraform near buildings.
3) Anyway result will be ugly because of tools too blunt.

I think that:
1) Buildings should not to interfere the terraform beacons work. It should just ignore buildings (not terraform around it). Only agents should interrupt it's work.
2) Need to decrease size of raiser/smoother red square size.
