OK, I think I fully understand now.
Replicating your setup, I encountered no warnings or problems:
- I created a schematic containing the display symbol, a matching
single-row header (16 pins in my case), and a few random components and
connections, including two connections to a GND plane. Both the header
and the display have netlisted pins.
- This was imported into PCB, with the header not yet overlapping the
display connections.
- I then set the desired thermals for both the display AND the header pins.
- As a last step, I placed the header pins over the matching display
pins (with snap to pins and pads active for easier placement).
The result is as desired: connected thermals to the GND plane, and the
DRC check does not flag any problems (not even the overlapping pins),
and the bom lists both components. There was no need to fiddle with
clearance (K) etcetera.
The only thing I noticed is that the thermals can't be changed if the
header and display pins are overlapping. This means that you must set
thermals before you move the header to match the display. Also, thermals
must be identical on the pins of both components.
If you want to change thermals afterwards, you'd have to temporarily
move the header or the display.
I hope this helps,
Best regards,
Richard
