Kalamazoo Veterans (ID: 0000003ccee4f3be) Voted 4 ★ - Updated 01/25/2023 The tool seems to be very helpful. However, the numbering system on my protractor is counterclockwise and I am unable to rectify the problem 90 is 270 and vice versa. I've tried uninstalling and reinstalling multiple times and it appears to be the default. Please help!
