When I measure angle with Protractor tool, it show me incorrect number.
For example, the angle is exactly 37 degrees, but Protractor shows me 37,4.
When I draw the same object in AutoCAD, it shows me correct 37.
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
some more numbers… i was curious to see what .001º looks like in a scenario i can picture in my head. (because in any practical application i use, i can’t imagine a scenario of being able to tell the difference between 0º and .001º)
so… a line 100m long (roughly a football field)
1º rotation is 1.7453m error
.001 = 1.7453mm
if throwing a dart to the moon from earth ( ) and your aim is off by .001º ,you will miss your target by ~4 miles.
(using 238,900 miles as distance from earth to moon)
