So far so good, but can we trust SketchUp on being accurate here? The shown angle is only in 3 decimals while the lengts may be displayed in up to six decimals.

Little test (only for this case!, but still,) with the help of Excel to see if the protractor does accept more than 3 decimals to see if I should trust SketchUp.

Precision in displaying lengths set to 0.000000mm

base 34000mm --> protractor angle input 37Â° --> height 25620,837703mm

base 34000mm --> protractor angle input 37.4Â° --> 25994,962853mm

34000mm --> 37.405Â° --> 25999,664617mm

34000mm --> 37.4053566Â° --> 25999,999970mm

34000mm --> 37.40535663Â° --> 25999,999999mm

34000mm --> 37.405356631Â° --> 26000,000000mm

(scaled up 100x to continue checking the protractor angle input)

3400000mm --> 37.405356631Â° --> 2599999,999962mm

3400000mm --> 37.405356631408Â° -->2600000,000000mm

It seems that the protractor accepts far more than 3 decimals.

Unfortunately though, SU only shows 3 decimals.

But I think I can trust SketchUpâ€™s accuracy on this one.
