You need to use EasyEDA editor to create some projects before publishing
Way in the future: PCB Lib: Arbitrary cut-out area?

Just an idea for way down the road: The ability in PCLib to define an arbitrary shaped holes, cut-out lines, slots, etc. Reason: There are devices such as the ST PowerSO-10RF package that have "submerged" mounting configurations - where the "pad" for a component (in the PowerSO-10RF case, the 'Source' of the MOSFET) is actually on the bottom layer of the PCB to allow direct mounting of a heat-sink. There are also critters such as heat-slugs, etc, that are not round. How: Similar to the "Solid Area," "Copper Region," or "Pad" function - so it is possible to define area that needs to be cut away (and possibly even how deep?) during the hole drilling process. Something similar to Altium's "Pour polygon cut-out" Why: Creeping featurism.

Hi 1. You can use the pad's shape to polygon, you can editor the polygon. 2. use solid regin, but add a solder mast layer out the. 3. solid regin can be used as arbitrary shaped holes cut-out lines, slots set it to NPTH ![enter image description here][1] [1]: /editor/20160303/56d78b7a8643d.png
