Object Location Confusion

[Geoffm]

Fascinating. Which operations in AC3D actually use the location reported in the Object Property window? How is the location used? I have only ever used the centroid. What would happen if the location is set outside the object?

Minor Bug with the Property Editor visible on screen:
When you rotate the object manually using mouse click and drag the location updates when the mouse is released. The exact rotate (eg 30 degrees about Z) only changes the Loc xyz when the property Editor is re-requested (F9) .
This occurs even in Object mode. It should update for both tools.

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.
