3. selecting trace and pad (flash)

4. fabrication -> teardrop (chosen teardrop) -> ok

Thanks for sending the sample file.  The reason the teardrops did not occur in certain regions what the pad and trace has a different composite level. 

Composite level determine what's dark/clear and the sequence in which the objects are drawn.  We have updated FAB 3000 to create a teardrop no matter the composite level - assuming both are the same polarity (Dark or Clear).  Here's a screen capture of the teardrop feature now working in those areas, and we'll have the update of FAB 3000 available in a few days.

Best regards,
