CAD Notes:-

Cad systems never cater for any of the extra information that needs to be passed over. One of the best ways is to add any extra information onto the edge layout drawing. This extra information could include anything for example copper weight, laminate thickness, profiling tolerance and size, slot dimensions, the list is endless.

On circuit boards with a complicated profile it can be of great assistance if the profile [or any cutout] is fully drawn along the perimeter of the board. As it can then be directly converted into machine commands for our NC routers.

One last thought, it's also good practice to add text onto each layer, which will be the correct way round on the finished PCB. You might know which way round your board should be, but if you have departed from the norm and draw it looking from the solder side. Without the addition of any text your board could well end up been made the wrong way round.
