I am building a SOT143 package and when I calculate the footprint the larger pad for polarity is on Pin 1. I need to change it to Pin 2 and I thought previously FPE had that functionality added but I am not seeing how I can change the polarity. Can you advise? |

Did you try the "Mirror" feature? |

I did Tom. Polarity needs to be on pin 2, which is lower left as you are seeing the footprint preview.
I have tried every combination of L/R/U/D and mirror and get the polarity set on the LL where I want it, but when I redorder the pins the polarity pad is flipping to the UR pin and the pin number reorder themselves from 1-4 CCW with pin 1 UL to to 1-4 CW with pin one now LL and polarity pad on pin 3. |

After building the part left-click on the pin you want to be the new pin one. Then right-click and select 'Reorder Pins'.
Left-click on the pins in the order you want them to increment. Right-click and select 'Done Reordering' and save or build.

Jeff, when I calculate the part the pin order is set the way it needs to be. Pin one is upper left in the preview window and the pins increment 2-4 counterclockwise. Pin 1 has the larger polarity pad. I need the polarity pad to be on pin 2. It seems to be blind luck using mirror/orientation buttons to get the larger pad on the lower left pin. When I do that and try to reorder the pins back to where they need to be it goes haywire.

I have captured screenshots of what it is doing. Is there a way to upload them here or can I email them to you?

Hello!
Did you get this problem solved? I've got the same one and can't understand how to use the "Reorder Pins" functionality... I would like to generate a "SC-82AB" footprint. Unfortunately I can't get pin 1 (small) and pin 2 (large) placed according to the datasheet... Please could you tell me, what am I doing wrong? Thanx in advance... |

This is fixed in V2015.06. This is a SOT143 Reverse.
