I just had a ring printed for a client which was slightly different in width than he wanted.
This was probably due to shrinkage, which is fine, but then I got to looking at the
dimensions of the model. When in Edit mode the width (or height in Shapeways world)
shows as 3mm...

Original Bounds
In: 0.8 w x 0.8 d x 0.1 h Cm: 2.0 w x 2.0 d x 0.3 h

Oriented Bounds (used for determining printability)
In: 0.8 w x 0.8 d x 0.1 h Cm: 2.0 w x 2.0 d x 0.3 h


But in non-Edit mode the width is 2.5mm.... Why is that? Simply rounding?

cm: 2.016 w x 2.016 d x 0.25 h in: 0.794 w x 0.794 d x 0.098 h

Edit mode gives dimensions rounded to one decimal place, so 0.25 == 0.3 which indeed seems
less than ideal for small parts.

SW might want to fix this (surely just a format string issue - guess it might have been introduced
with the recent ad hoc addition of the density)

(BTW I just noticed that in your example, both "original" and "oriented" bounds appear to be identical.
Cut-and-paste error in your message?)

Figured it was something like that.... and no, I just double-checked, the original and oriented bounds are both exactly the same...

(Exactly the same due to the rounding... silly me. The 2.016 would reduce to 2.0 in the "abbreviated" format)
