Hi All,
if there is no way out, what else should we do than to disable the Acute angle design rule.

Subject: RE: [PEDA] Acute Angle DRC error for Polygon Fill
Jeyaraman,
The Acute Angle Constraint just doesn't work. It checks polygons which have numerous acute angle violations (if it is anything but rectangular and even if it is there are arcs and angles around clearance items) and it erroneously reports short 225 degree jogs as less than 90 degrees. So give up it is useless, I just went through the exercise a few weeks ago only to recall why I had never used it for the past 5+ years.

Hi All,
When ever I enable Acute angle on the DRC setting, I receive a longer list which includes errors relating to polygon fill along with errors on traces. I would like to see only the errors relating to my traces.
Could anyone guide me to any of protel tips and tricks [which I must have missed] or advice on the methods to achieve the above.
The settings I use to fill my polygon are
minimum primitive size length - 3 mil Grid size - 8 mil or 5 mil track width - 10 mil or 8 mil
The DRC setting for acute angle is 'less than 45Degree'
