I have very interesting problem by using SW 2016 SP0.
I'm working on my master's thesis which goal is to parameterize the turbocompressor's stage.
The problem is about 3D-sketch. At first I specify the angle between two lines (picture 1), and then, when I change its dimension in parameter's sheet, displayed angle have become wrong (picture 2). Points of lines belong to circles.
Is it problem of SW or maybe I did something wrong?
P.S.: angles have become correct, if changes are not very significant (less than 2 degrees).
