I searched the forum and did not see the solution I will list later on how to increase the size of Borg Cubes, bases, Star Destroyers, Death stars etc so in the meantime I will post a picture below showing the USS Vengeance up against a Borg Medium Sized Base. The Larger Borg base is 25% bigger than what is shown in the picture below and dwarfs the Federation frigate.
The Borg Cubes I have attached to the Base below are the same size as the individual Borg Cubes set as Carriers etc but I can make them much larger if needed.
This will allow me to setup some huge battles with several ships being required to take down a single Borg Cube.
I have resolved the issue where the Borg Cubes look thin and crushed.
