Changes on 08-02-15:

• Added the ability to dig or demolish go exits inside of an architectural design simulator. To add a custom exit, type DIG-GO <exit name> to <room name>. To demolish an already built go exit, type DEMOLISH-GO <exit name>. Be aware that these two commands will not work in real structures and are only available in a simulated environment.
• Added the ENVIRONMENT-command to architectural design simulators to alter the environment of the room you're standing in.
