Building footprints

[Wolverine@MSU]

The Auto Plant (and perhaps others), when upgraded, will build into an adjacent building as shown below:
Before upgrade

After upgrade

Don't know what other upgradable industries do this, but I'll do some testing.

Was the auto plant there first, or the other industry? Can't see, but is that the explosives plant or electronics factory...they may need the adjustments to the bty file.

Sorry I didn't post the first picture. It was a Plastics Factory that was there already and I built the Auto Plant right next to it.
