Im so annoyed that this bug still isnt fixed by the developers.
When I measure minimum distance between two cylinders, it returns the value of the minimum distance + the diameter of the smallest cylindrical face. This is happens often, and as far as I remember typically when one of the cylinders are inside the other.
There is a workaround, by using custom distance and the first arc condition on maximum and the second on minimum (or vice versa). However, it is really annoying having to change this setting, when the minimum distance should return the correct result!
