PCB holes with partial plated surfaces.

hi!

i’m trying to make a Eagle library for banana and mini-jack possibility, the idea is to have a big partial round pad (arc) for the banana connector and the necessary pads for the mini-jack. Recently i sent a design like this with the file attached where i choose the ‘PJ_360_BANANA’ package, the result was a pad where the bottom and top is not communicated by the plated inner surface (the inner surface is not plated). I assume this is because i put the hole in the ‘HOLES’ layer, now i make the package ‘PJ_360_BANANA_2’ which has the hole drawn on the ‘MILLING’ layer, this can solve the issue? or: is possible to make a pad composed by an arc of the hole with the inner plated? Thanks
BTW: the lbr extension is not allowed?

hi there,
there are 2 way to design plated solt.
1.the best way is overlap drill holes
2.draw the solt in milling layer, and point drill slots with copper.

hi!

thanks for answer, but i don’t understand this: ‘.the best way is overlap drill holes’ or ‘and point drill slots with copper’
the hole is already drew on the milling layer, can you explain me a bit more please?
