Reason of failed review:
Screenshot shown as below, you may find the outline vertical are very thick, we need to confirm the final dimension of PCB should be subject to the inner, outer or the middle of the line.
Suggestions:
Better not design outline in shape of routing/milling and without consideration of diameter of router, but just draw as horizontal line shown as below,the middle of the outline will be measured for the boards dimension. If cannot control this in design, then just clarify the final dimension online when you create order online.
