Dom,

Go to 'Rules'. In 'Acute Angle Constraint' choose 'Net Class' for 'Filter Kind', then 
click on 'Edit Classes' and add a new class. In that class put all nets except nets 
connected to your polygons. Then, once back in the rule dialog, choose the net class 
you created from 'Net Class'. This rule will not check polygon outlines.

Regards,

Igor

Subject: [PEDA] DRC acute angle on polygons


I'm new to Protel (although definitely a consenting adult for pcb design ;-)

I have DRC set for "AcuteAngle Whole Board min angle 90.0deg"

I'm having some trouble understanding how I handle the voluminous error 
report when I do a batch DRC on my 2 layer board. It has lots of 
polygons that I have constructed with a tracksize of 12mil & a grid of 
10mil (& thus overlapping to form a solid copper area). It seems that 
"within the construct" of the polygon there is obviously areas where an 
acute angle of < 90degrees is formed, that's obvious, but this seems to 
me to be checking at too low a level. I only really want the checking to 
be on individual tracks & the outline of the polygon. Have I missed some 
way of getting this to work properly?

How do you do it (or do you turn acute angle off)?


Thanks in advance
