First let me thank you fro the time you spent to write for us here ; About the part rotation, you need to move to your Pick and Place file and check the part's rotation, any change in the Pick and Place file will impact the assembly viewer so if you change the rotation of a chip from 0 to 180 degrees then when you re-upload the new Pick and Place file you will see the chip flipped 180 degrees, you can do this with the parts that has a wrong orientation and I advice you to read the following description that tells some tips about the SMT Assembly parts orientation : [https://support.jlcpcb.com/article/99-does-the-red-dot-means-pin-1-in-the-placement-previewer](https://support.jlcpcb.com/article/99-does-the-red-dot-means-pin-1-in-the-placement-previewer)<br> <br> Thank you again Mike, anything else, just let me know ^_^

The automatically generated Pick and Place file was incorrect for some reason.  I changed to another part as that was the easiest solution rather than edit the file every time it was generated.

@MikeDB Could you submit an Error Report for your original part?
