Orbit is making me feel sea-sick!
Is there any way to orbit only around a vertical axis - i.e. to at least keep the verticals vertical?
After 2 or 3 hours on Sketchup I could have sworn that the vertical lines in a different application were squint. However it now seems that I had been spending too long looking at a Sketchup model with verticals “off to the left” as it were !
Holding down shift put it into pan mode of course I have tried holding down control and/or alt or both, but they seem to have not effect.
