Extent of construction

[c.pergiel]

I am looking for a way to determine the largest dimensions of my construction so that I can center it in the display window. BeginQuery and EndQuery looks like it might work, but it looks a little cumbersome. Is there another way?

Compute the bounding box and center on it.
