MakeIt 2D Wrong Angles

Wondering if anyone else is getting wrong isometric angles using MakeIt 2D by EMT software for AutoCAD. You have to increase your units decimal
display to see it. For example instead of 150 degrees, you get 149.7801542000. Or instaed of 210 degrees, you get 210.21984578.
The error is more than enough to throw you off the snap points, even in a small drawing.
Any help?
