How to Accurately Measure All Subtools

If you want to manually measure the model, you can do so by generating

a fitting box either around JUST the body or the WHOLE model.

while New bounding Box Subtool generates a fitting box around all subtools.

which includes the height or thickness of the hair.

and when I open up Subtool list, at the bottom I will see the generated bounding box.

Snap and click at the top right point of the box,

then snap and click at the bottom right point.
