Please see attached file.The rotation snap (drag while holding shift) is erroneous. I created a right-angled triangle (red in the attached file) with the catheter lenghts 1 and 2 respectively. This gives offcourse 30 degree [sin (1/2)] angle in the top of the triangle. But, if I rotate some thing (blue rectangle in the attached file) while holding down shift key (i.e. two 15 degree snaps) the angle is about 33.5 degrees and not 30 degrees. This is a major bug that needs to be resolved quickly.
I have the latest designer version, running windows 10.
This bug is propably also present in the photo (and upcoming Publisher) versions?
