Center works fine - Arrange is broken.
Arrange uses a very primitive algorithm. It does not seek symmetry or try to create an optimized pattern to consolidate your parts to the center of the bed. I find myself rearranging parts EVERYTIME I print a group of parts.
For example - load in a small part, press CTRL+D to duplicate models an enter 8 (for a total of 9 parts). It creates a horizontal line of 9 parts which starts in the center and probably runs off the bed.
Now, press center and arrange (CTRL+R). A proper optimized pattern would be 3 rows by 3 columns. That's not what it does... It creates 2 columns, with one column containing 5 parts, and another containing 4. Only the first row of parts is centered front to back. The second row is offset from center.
To make matters worse, the very useful interactive positioning tool was removed in 3.02. In 3.0 you could click the positioning tool, click your object axes and move your part around interactively in a constrained way. In 3.02 those arrows no longer work. You have to use Position/Scaling/Rotation panel and click the numbers in the little number input boxes. It's not as interactive. A step backwards, and serious enough to cause me to revert back to 3.0.
