I am using TextBlockVisual3D to display multline text (each line separated by \r\n).  I would like each line of text to be centered.  I've tried a few things, but nothing gave me the result that I am interested in.  What is the best way to display three lines of text with each line centered?  See the attached image for example.  I want HDPE, 19.87', and 134,840 lbs to be centered on that yellow cylinder.

Thanks,
Arthur
