as you can see in the image, there si circular shape in the middle - if i try to rotate it along its round side it wobbles up and down
it seems to be perfect circle and even if i take outline (edge) and compare it with newly created circle it both creates an object, that perfectly fits (the rounded object in the front)
the point is, that if i duplicate the middle object and keep rotating one - it is visible form isometric view (right/left in this case) that they do not cover each other perfectly
furthermore, if i join the last object (quater-egg-like shape in the back) to to cicrle one, it wobbles even more. The back shape does not exceed the circle dimension, so i expected that these two object together will share the same center of rotation given from the full circular shape. The difference is quite big at that moment and even shaper calculate different position after rotation
I checked that the back object does not exceed the circle object by using the outer circle outline to cut any exceeding parts on the back one - but it did not cut anything, it simply created a new object around the back one. (i would add an explanation screenshot in the comment)
the outer oultine of the circle is clear with no parts exceeding in or out. I get, that this could change the center of the mass, but this is not the case
the object is 89.7mm in diameter and the difference is 0.2mm
the origin of this possibly comes from the fact, the object was created from rotation of a sketch, then shell.
But why does it translate to clean circle in one case and then behaves like this … or is it only display glitch?
