I don't want to make a big thing of this - as I said it was easy to work around. However, the? board *outline*?is supposed to have zero thickness - it is just a bounding box not a physical thing. The reason for plotting it on all layers is it helps the manufacturer visualize the overall shape of the board no matter what layer they are looking at which is important for assessing manufacturability e.g track to edge clearances. But as I say it is not a big thing, it only occurs with Aisler and it is easy to work round.
The more serious issue was them not properly finishing the sides of the PCBs. For boards that do not have to plug in it is not an issue but most of my boards need to plug into Eurorack card guides and it is a serious PITA to have to do this manual operation on every one. As I said, only Aisler has this problem and even after discussion they were not prepared to do anything about it. Seems to me they were not what I would call "beautiful boards" which is what they claim to provide. I was really disappointed because I really wanted to move away from Chinese production and Aisler were by far the best value in Europe.

Well they are just doing what your Gerbers call for, which sounds like a
positive thing to me.? ?What if you /wanted/ the outline on all layers,
but found the manufacturer was removing it?? ?I've never plotted the
outline on all layers, because I don't want it on all layers.
