Why the size differences between Edit and non-Edit mode?

    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)
