Figure 1-15 shows how you can work around this issue to successfully implement areas containing voids. Figure 1-15 Areas Containing Voids Also, when importing IDF files from Allegro PCB Editor to Pro/ENGINEER, be aware that ECAD areas such as PLACE_KEEPOUT are not imported into the database in Pro/ ENGINEER. Components Coordinate Systems in Pro/ENGINEER are the key to successful transfer of component placement between ECAD and MCAD systems. Since this transfer takes place between a three-dimensional and a two-dimensional environment, you need to clearly specify the Primary (top) and Secondary (bottom) sides of the board and locate both the Component Coordinate System and the Board Coordinate System at the bottom surface. The location of the component coordinate (Figure 1-16) shows a Pro/ENGINEER part model with the Component Coordinate System ECAD_CSYS at the wrong location, inducing a mounting offset, which is set back to 0.0 while importing data into Allegro PCB Editor. An IDF export from Allegro PCB Editor to Pro/ENGINEER reports that this component has changed its location.
