HL 8.0 Allegro Translator wrongly interprets arc traces, it treat every arc in one direction(Clockwise /antiClockwise solely). I have logged it in the supportnet,hope it can help Mentor to  can eliminate this bug a.s.a.p

 

Allegro's Extracta clearly dipcates the arc direction, here is the example etch data from Allegro:

 

S!ETCH!TOP!RA 00000010!RA10!85 7!ARC!256!2743.83!3258.03!2757.98!3243.88!2750.90!3250.96!10.01!5.00!CLOCKWISE!CONNECT!
S!ETCH!TOP!RA 00000010!RA10!85 8!LINE!257!2757.98!3243.88!2687.94!3173.84!5.00!!!!!CONNECT!
S!ETCH!TOP!RA 00000010!RA10!85 9!ARC!256!2687.94!3173.84!2702.09!3159.69!2695.02!3166.76!10.01!5.00!COUNTERCLOCKWISE!CONNECT!

The workaround is using .DSN if you don't do PI analysis in HL 8.0

 

This symptom was found by one of mine budys.
