Hello, The fab house I'm using has encountered a problem importing my RS274X artwork. I believe their software is having a hard time compositing(?) the power plane layers. I'm still unsure what exactly is happening - I plan on visiting them tomorrow and see first hand. My software (output) - Allegro designer - version 13 Theirs (Input) - Tibor Davos - version unknown. Has anyone else experienced any difficulties with RS274X formatted power and ground planes generated from Allegro?? Any (I do mean ANY) help would be appreciated.
