Designing Switch Bezel using A-Class surface in CATIA V5
Draft Analysis.
Designer Final inspection This Drafting, Design Model If Manufacturing Are Not Checking In This Analysis method.
In Industry This Draft Angle Value is Standard For Injection Molding Process.
Minimum Draft Angle 3deg Maximum Draft Angle is 5deg.
What is Draft Angle?
Draft angles are very important in thermoforming product design
A positive draft means the angle of the face, with respect to the direction of pull, is more than the reference angle
