This tutorial shows you the capabilities and what you need to do to achieve elongated holes, plated and non-plated slots and cutouts.
tldr;
We support plated slots with a length of up to 15.0mm (5/8 Inch) and a width (or tool diameter) of 0.7mm (0.027in) to 2.8mm (0.11in).
Typical use case of plated slots.
As we give a gurantee on our renderings you should always use the Board Viewer to check if plated slots are detected properly. Use the "Highlight Drills" Button for this.

This plated slot will be manufactured properly, shown by the orange color.
Eagle Users should always check if a slot was detected as plated or non-plated slot.
Non-Plated slots have the same minimum size as plated slots of 0.7mm (0.027in) and maximum length of 15.0mm (5/8 Inch). Please note, if the slot is longer it may be milled but in this case its diameter must be above 1.8mm (0,07in). Use the Board Viewer to check how your slot will be manufactured.
"Milling Path" used to display milling of non-plated slot. In this case on a Raspberry Pi Hat.
Non-Plated slot highlighted in blue color.
Same slot as shown above.
Cutouts will always be milled and may have any shape you like. A milling tool with 1.8mm (0,07in) will be used, because of this all cutouts need to have at least this size.
