In PC Rhino you can double click the four viewport icon and it re-aligns all four viewports so the origins line up, but that doesn’t work in Mac Rhino.
Right. What you’re seeing in Windows Rhino is a side effect of discarding your current viewports and building 4 new default ones.
Both Windows and Mac Rhino have a better tool called Linked viewports.
In Mac it’s in Rhinoceros > Preferences > View
In Windows it’s in Options > View
Found it! thank you!
