There is nothing mystic about it, it is just a technique. You set distance between tracks to zero and Protel stacks them up with no space in between. If you then choose to pour tracks in only one direction, e.g. horizontally, your file size would be even smaller. But then you should choose fairly small minimal polygon track length, to get a good coverage in tight areas.

Ok - this is bizarre - I just tried that on a 800+kb PCB file with 2 large
polygons - I changed the grid size to zero and it made the final PCB size
20kb SMALLER.

Must be an 'undocumented feature' methinks...

Doesn't that make your file size very large?
Or is this one of those 'undocumented features'?

Hi Brad,

>> Oh one tip for you, if you set your polygon grid size to
>> "0", it will pour the track widths edge to edge every
>> time giving you a solid polygon regardless of the track width.

Oh! Very COOL - Haven't figured that in over 5 years! Have just checked this
on 99SE and it works just fine.


The artwork I used to test your 'tip' uses some fine dimensioning and
pad/component placement.  The outer limits of polygon pours were previously
rather ragged in various places.

Your 'tip' completely cleaned up these areas with no other changes.

Regards,
Jim Parr
