I have a very simple sketch on a part and for the life of me I can't get it to rotate. In the part I am trying to rotate the middle triangle. If I draw another object anywhere I can rotate it using the rotate tool fine. Yet when I select that specific triangle, I type in the rotation angle and then hit tab, nothing rotates. I get a blue axis symbol on my rotation point but it doesn't move the sketch at all. I have attached the part (SW 2016). Would someone mind having a look at it for me please?
