比如：灰色框是板框，红色环形区域要开阻焊，结构给了开阻焊区域的外框和内框，我把结构图外框 直接zcopy成solermask层的shape，结构图内框 如何zcopy成这个shape的void？以实现环形开阻焊？4 P5 N) {) Z: d' M% e2 |6 M, s" U

Hi all,
. ?6 z% x+ u* `I am trying to create a ring of exposed copper at the edge of a board by creating a shape on the solder mask top, however I can't seem to make an actual ring rather than a big filled plane. I can use z-copy to get the outer edge from my route keepin, but I can't figure out how to use a shape to generate a void (I would love to use z-copy to make the void the same shape as the route keepin, but contracted by 30 mils). Any suggestions, or is there something really obvious that I'm missing here?" @. q9 O7 C; _
Thanks! sp7 J7 y' ~+ v8 \0 k

* k# g/ p% k% oI found a way to do this. If you create two unfilled shapes that represent the inner and outer boundaries of the ring (I did this by z-copying the keepin referenced above, once the same and once contracted by 30 mils, and decomposing both resulting line/arc items) compose a shape using these, it creates the ring exactly as I wanted it. I was going to delete this post, but I figured anyone looking for this might want my solution...+ @; L- [7 ?6 K% H! N7 b, I
