1. Joint Logic control
● OR Logic: Either 2D or 3D pass will consider as pass.
● AND Logic: 2D and 3D must be passed to consider as pass.
2. Fillet Gradient Thres
● To enable Fillet Gradient Inspection.
● Unit in degree.
Bumpy Detection
Slope Detection
Length Detection
3. Fillet Image Plane
● These are the types of 2D Lighting. Select the one with having
highest contrast among interested inspection region and the
background.
● Usually choose angle 2+3
