rotation mapping automatically flip the rotation sign if the layer is top or bottom

[gionag]

If i save a mapping for certain package on the top layer, when i use the same package on the opposite layer, also the sign of the rotation should change.

Should internally adapt the sign if the component is placed on top or bottom

Maybe is a recent change on jlcpcb portal

Can you give an example so that I can test it?

I came across the same (?) problem on my double sided board.

To my surprise the correction "sign" switching was already implemented here:

After removing this condition (i.e. always True), I've gotten correct results on both sides. Strange.

I was able to reproduce the issue with standard kicad library footprint.

Example footprint is TO-277A with C895438 - rotation 90deg. Top: Bottom:
