richmon74,
Your post was OK, and Technical Info, or Tools Comparison is OK too in Elektroda. The follow-up post was indeed irrelevant to your Technical Info request.
It looks like Protel DXP is gaining ground, even though being perceived as a weak PCB tool. Still - the top leaders are:
Mentor Boardstation (WG2002),
Cadence PSD (AKA Allegro),
Mentor Power PCB (formerly Innoveda, Pads Software).
The 2 later have also interface for 'Specctra' - the BEST PCB router. Some people consider PowerPCB 'BlazeRouter' to be 2nd to none.
A GOOD PCB tool should also be measured by its 'interfaces' to other tools. PowerPCB is VERY good in importing/exporting databases from/to other tools (importing popular Schematic Capture databse - alike Orcad - is another criteria). Supporting ECOs, and backannotating ECO to Schematics.
