In Draft Analysis given angle is 0.5 degree and yellow face found that needs draft. Then went to draft and 1 degree draft angle is given to prepare that face for drafting. Here Draft Analysis tool and Draft tool has been used to prepare this face for drafting. My question is if you give 0.2 degree instead of 0.5 degree, you can get rid of yellow face. What is the reason for giving 0.5 degree?
