Fallout 4 Coliseum Style Settlement (Building Curves)

This video will help with building round or curved structures in Fallout 4 settlements. The larger the building, the more seamless it becomes.
I should add, the "Unlimited Power" from the Circuit Breaker to the south is limited to objects that do not directly connect with a power cable. You can still connect objects such as turrets. As long as you don't go over the 20 power units it offers, you will continue to receive infinite power on objects that do not connect directly, such as lights.
