Hi All, I need help on verify issue. Please see these pictures. They are in WCS: LEFT SIDE view for clarification. I try to drill 8 holes equal space on Ø4.00 rod. In toolpath parameter, It was set Planes (WCS) (Working coordinate system = Top, Tool plane = Top and Comp / Tplane = Top). Rotary axis postioning, Rotate about X axis. The left picture is backpot. It looks like the tool goes into the hole perpendicular correct. The program also posted out correctly. The right picture is verify. It is going from right side into the hole, not perpendicular into the holes. I have search the Google and especially in here, nothing was come up close to my finding. I played around Backplot Options setting, checked box Simulate Rotary Axis, checked box Display Vectors, connect top and 1.0 length. Nothing had help. I am using Mastercam 2018. Any helps would be greatly appreciated. Thanks in advance All. Newbobi
