[PCB_FORUM] Re: Allegro V15 help with copper shape

Oleg,
 
    When you created your planes you specified a minimum aperture size
for checking.
If you ignored the errors when creating the shape, then when you created
the artwork
you got the can fill shape error.
    Go back and correct these shape errors and carefully specify the
proper aperture, based
on copper weight. This should clear up your problem.
    You might also check that your board accuracy is set to only one
more place that the units and
when you output your data use one more decimal place.
 
For example:
Board units is mils    .000
Accuracy is 1:          .0000
Gerber output 2:5:    00.00000  ( this is the max for Gerber)
 
Good Luck!

        Hello Allegro V15 Gurus,
        

        We got pcb file from customer in order to make panelization. 
        I'm trying to create gerbers (on format Gerber6X60-this is only
requirement of our 
        fab. vendor) and on top side (l01) during creating gerber I got
zillions 
        error "Can't fill shape at (x.xxx, y.yyy). 
        If I start to eliminate those small area I will loose the
integrity of grounding 
        shielding on pcb. 
        So my question is:  
        Why Allegro lets create shape in small areas, during shape
checking
        it (Allegro) finds 0 problem and finally during creating gerbers
it can NOT
        fill out those spats?
         How do you handle this situation? Is the way to create 
        gerber (on Gerber6x60 format) and not to change copper shape?
