Ground polygon removed at the edges

nikhil2402 , 10-08-2018, 04:03 PM
Hello Everyone,

I have been facing the following problem:

When I pour a ground polygon and have cutouts around certain pads, the ground misses to fill at the corners of the cutouts as shown in picture below.

I had this problem sometime before as well but I solved it with some trial and error. But this time I am not able to get rid of this.

Does any one have a solution for this?

I have the same issue once i a while, no solution found.. can live with it in most cases.. it is a rule thing or at least thats my guess... havent checked the altium forums for this particular thing..

Please review the Polygon-Pad Clearances and Polygon Dead Copper Region.

as @mohsin_qau is suggesting, have a look at polygon properties and rules. You may want to try to use smaller numbers there:
