Steps followed:

1. file -> new job

2. import -> ipc 2581 -> selected the xml file. -> open

3. selecting trace and pad (flash)

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

after this step no change occurs, but while manually imported Gerber data able to produce teardrop.

below images for your reference.

IPC-2581 data (no teardrop)

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. https://support.numericalinnovations.com/support/discussions/topics/14000002419

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,

Simon
