Got in a right tangle trying to add a modified part to the System library so here's the same part contributed directly by me.  It has all the LCSC part numbering BoM info etc. (but no image or automatic links to the LCSC page) but has the pins renumberd as D, G and S to ensure that the pin mappings of the 3 pin symbol map properly onto the 9 pad footprint. * This should no longer generate DRC errors. When I find it again I'll post a link to a forum  thread that describes why I do this sort of package this way. :)

Sorry: my screenshot hadn't caught up with the name... Search for: CSD16340Q3\_DGS\_PINS 

This is the thread that gives more background on this pin mapping issue: [https://easyeda.com/forum/topic/Drc-errors-with-library-component-f42b0deca29a47df944623bbeff22184](https://easyeda.com/forum/topic/Drc-errors-with-library-component-f42b0deca29a47df944623bbeff22184)

Thanks andyman, that did the trick. Although the pads are quite close, so I had to set the DRC rules to 5 mil clearance. I noticed that the schematic symbol is acually much simpler.. Original symbol had multiple pins, but drwan on top of each other. So it looks like onepin. But with your approach that is not required at all. Again thanks!
