Removing Dead-Copper from a split power plane

[LimeyDave]

Hi All,

As the subject says i'm trying to remove a section of an inner layer power plane. The section of dead copper (which has no Net Label) is underneath a couple of relays so the pins voltage potential could get quite high (240V) which is why i'm trying to remove it from the rest of the power planes, any suggestions?

My only thought was to fill the area using the "square area" icon and cover the section. It looks ok on the gerber file generated, but is there a more elegant way or properties option that i've missed?

Regards,
Dave

Place an arc/fill on the plane layer to create a plane "blow-out". Then regenerate the split planes. The copper should be removed from that area.

Cheers Marshall,

I'll give it a try in the morning and let you know how it goes.

multiple options
- placing a fill
- placing a polygon cut out
- defining a keepout region

i'd go for the keepout region and draw it as multilayer. that way the cut is automatically done on ALL layers and you'll never have to worry about it if you inject it in the database then it becomes even easier as the zone now moves with the part so you don;t have to fidget with that stuff all the time.

Does multilayer polygon cutout work with internal planes(as opposed to internal layer with manually poured polygons)? Try as I may I could not get it to do anything there. Manually placed cutout on the same layer works fine.
