I tried to export example/orcad/rs232_cm.asb to a pdf file.
Unfortunately the pdf file generated is unusable:
1. When just exporting the layer without any modifications, the labels "D1" and "R1" are missing. (see rs232_cm.unrotated.pdf in attachment)
2. When exporting the layer after rotating it 90 deg CCW the labels "D1" and "R1" are there, but garbled. Furthermore the outlines of the board are not meeting each other at the ends, and the pads are not centered in the surrounding boxes. (see rs232_cm.rotated.pdf in attachment)
