When executing the 3D command in Allegro PCB Designer 16.6, the top components are placed correctly with the smt leads flush on the top conductor surface. However, if I rotate the design from within the viewer to look at the bottom side, the bottom component smt leads are buried in the board and are not sitting flush on the bottom conductor surface. It is almost as if the board thickness is being taken into consideration. Am I missing a setting?
