My design has an imported step file comprised of a PCB with an Ethernet jack hanging off one edge.
The PCB already has standoffs placed, so I won't be making use of PEM mounts. I only need to align some thru holes on the bottom, and cutouts for the Eth jack and some led's on the back panel.
All is going swimmingly (nice work folks!), except the Problem Checker (which is automatically invoked every time the file is opened), complains about the Eth jack protruding out the back.
Are there any steps to legitimately make this situation pass the checks? It seems like it's probably a common situation.
The design is using the 1U Rackmount template.

I tried to lower the PCB, and made the Eth jack cutout larger (taller).
No change. The checker still complains.

Hello Chris,
I think there is actually no problem. Really looks a like a false positive to me.
What I think is happening is the group the component is in intersects the boundary of profile of the face it is on. This may or may not be an issue depending on whether or not a gap exists between the adjacent face you are planning to add your IO cutouts.
Let me know if you disagree.

Hi Matt,
The group component was placed on the bottom panel.
The error msg indicates a problem with the back panel. This is confirmed by moving the PCB component away from the back panel (Y-axis), while keeping the Z coord the same. If this is done the error goes away.
This tells me that there is a detected collision with only the back panel.
The only bit that sticks out beyond the PCB edge is the Eth jack. The cutout in the back panel looks to have enough clearance for the Jack.
So yes, I'd agree that it's a false-positive (and it reassures me that you think so as well).
I'll try placing the 3D PCB Step component on the back panel instead. That's a bit of trickier math, but I'll see how it goes.

Re: Is the Problem Checker _too_ smart?
The Problem Check returns happy results when a 3D Step component that has panel-protruding bits, is placed on the same panel as the protruding-bits-cutout.
The moral of the story:
The moral of the story:
- When placing a 3D step file, consider which face has elements that need to protrude through a panel.
- When you go to place the 3D component, switch to the panel that has those protrusions, in order to edit that panel.
- Place the 3D component on that panel.
