The AC3d rotate tool can be set to use the Object Center, and it does not matter if the Object Center is inside the object or not.

Inside the .ac file each object is saved as if its Object Center was 0,0,0. Keeping the Object center near the object's bounding box can help keep file size down and precision up, for example, a vertex at (1000.1, 1000.1, 1000.1) would be stored as (0.1 ,0.1 ,0.1) if the vertex's containing object had its Object Center at (1000,1000,1000)

There is also a tool called 'adjust object centers...' that will quickly place the Object Center at minimum, maximum or centered on all 3 axises.
