Hello Allegro Gurus, When I run on Allegro V14.2 pcb through DBDoctor it gave me error: "ERROR IN SYMBOL DEFINITION name = UNKNOWN_DIM_TYPE Symbol definition has no instances". I looked all symbols but found nothing wrong. So ?? are: 1.what does mean this error 2.how to figure out which symbol on pcb(LOG file does not tell it) 3.By the way: where to find meaning all errors in Allegro (particularly like this) Thank you in advance Regards, OLEG KIPNIS x8286 PCB Layout Designer SMART Modular Technologies, Inc. 4211 Starboard Drive Fremont, CA 94538 Direct: 510-624-8286 Fax: 510-624-8195
