Thanks @maxz , Sorry - I wasn’t clear: at Print Width of ‘2’ the viewport doesn’t look anything like what it used to look like in Rhino 7, which is what I was expecting.
same units, same physical size, same print width, both in ‘print-preview’ mode, but very different viewport results. So was wondering if I needed to adjust a setting someplace to make RH8 behave like RH7?
