Geolocation continues to evolve, which is great.
However the notorious “widget” control has now made its way to the Geolocation window!..
When panning around the Map to select our location, it’s far too easy to accidentally grab the True North Offset adjustment and change it to some random amount.. Then there’s no way to easily change it back to default.
We need a Reset button.
But, ideally, please get rid of any widget-like behaviour from the GUI
The 0.45 degrees you are seeing there is due to the curvature of the earth.
SketchUp is modelled in a UTM coordinate system and the value you define in the web application determines the angle offset between the green axis and “True North” (the orange line in SketchUp).
Naturally the green axis points to what I call UTM north. By using the “reset” axes feature in SketchUp you are setting the axes back to their default state. You will also see an option “Reset to geolocation” when right clicking on the axes, which will align the axes back to the position they were in during geolocation.
