I made a custom footprint for an 8 pin TSSOP IC. Each of the four pins on a side are 0.3mm wide and 0.5mm apart (BSC). In the .dra file everything looks right. However, when I add the components into a .brd file, the pins have a couple issues. On both sides, the two middle pins are 0.6mm away from the corner pins, and only 0.4mm away from each other. Not only are these the wrong distances, it also doesn't add up to the correct total distance from corner pin to corner pin (1.6mm instead of 1.5mm). The pins are also only 0.2mm wide instead of 0.3mm. Any idea what could be causing this?
