I am trying to make a gear with teeth that are angled. I have the tooth profile and I want a -2.5º angle with a 6.1mm height. The entered height works fine but when I input -2.5º I end up with a 5. something degree tilt. I am attaching a screen shot that as an experiment I input a 1º angle. The screen shot is self explanatory.
As an aside I originally did a 7.5º angle which was wrong (In hindsight because of the problem described above) and I tried changing it in history. The angle in the history box changed but it did not change the object. This I suspect was operator error. Haven’t found a video with a good explanation of the steps to do this.
I had been selecting, extruding and rotating all of the gear teeth at once. I just extruded and rotated one and changing the angle in the history worked to change the angle of all of the teeth. The angle they change to is still not the angle that I m inputting.
