Problems with stacked components in Altium Designer [Copy link]

I don't know if I can explain it clearly. I bought a core board and designed an expansion board myself. I just plugged the core board and the expansion board together with pin headers. Now when drawing the PCB, it stands to reason that since the core board is plugged on the expansion board and there is a certain distance between them, components can also be placed under the core board. Now the question is, how to draw this situation in Altium? Because in Altium, if two components overlap, an error will be reported.

You don't need to draw your core board, you just need to draw your expansion board.

1. The core board and the expansion board are connected with pins, so they are designed separately. Because the 3D function of AD software to draw PCB is not the 3D effect of structural design, the assembly interference situation in PCB generally depends on the strict attention of designers. 2. In AD software, the setting of preventing component overlap alarm can be found in the toolbar Design--rules--placement,,,

Does it matter if you don't have to draw the core board? You just need to align the pins when drawing the expansion board.

There must be a conflict in the rules. Just take a closer look at the rules.

You don't need to draw the core board. You only need to draw the pads and silk screen where the core board is inserted (in short, the package of the core board corresponding to the base). For example, if the core board is a male socket, then the package on the expansion board of the base is the corresponding female socket.

That makes sense. When I drew the PCB library, I drew the core board library as two rows of mother sockets. So the space between the two rows of mother sockets will be wrong if they are overlapped in the PCB. I will change the package of the core board again.

OK, thank you. I understand

Thank you, I know what to do now. I probably won't modify the package of the core board, because I have determined the spacing between the two sockets in the package. I can modify the rule and uncheck the placement clearance in the rule.
