Hi Danny, yup that's a bug! I guess it slipped through since it was giving a kind of related value so it looked kind of reasonable at a glance.

But yeah it is supposed to give the full width and height like rect from center and plane from center were doing properly. Also it shouldn't report negative values for the tracking width and height either.

I've fixed this for the next beta.

The bug is in the UI so you can apply the fix pretty easily to the current release. Just take the attached BoxCenter.htm file and copy it over top of the old version in the \commands subfolder and then it should be working properly.

EDIT: Note - this fix should be only applied to a v2 beta, the v1 version of this fix see here: http://moi3d.com/forum/index.php?webtag=MOI&msg=2171.5



Thanks for reporting it!
