Edit symbol - multiple name pins

Let's imagine I have on the schematic a component (for instance a regulator) with only 3 pins: Vin=1; Vout=2; GND=3 but on the PCB the package is, for instance, a DIL8, so it has 8 pins Vin=1,2 Vout=3,4,5 GND=6,7 NC=8 How is it possible to map multiple pins on the package to the same pin on the schematic?

* In EasyEDA, a schematic symbol can have 3 pins as in you example but these can be mapped onto multiple pins in a PCB footprint. Here's an example of a MOSFET with Gate (G), Source (S) and Drain (D) pins in the schematic symbol mapped onto 1 Gate pin (G), 3 Source pins (S), 4 Drain pins plus a Drain Pad (D): ![enter image description here][1] ![enter image description here][2] In this footprint, the grey pad is on all layers and has a hole in it (purely to aid in hand soldering) and the 4 other D pads are just single (Top) layer pads that overlap the big D pad. To understand more about how the symbol and footprint are made, you can find the symbol by doing a SHIFT+F search for: `BSC042N03LS_G_3_pin_copy_DO_NOT_USE` and for the footprint: `UNDER CONSTRUCTION PG-TDSON-8 copy DO NOT USE` (Don't be put off by the names, they are under construction and test for one of my projects: you can clone them but use at you own risk because the footprinT has not be verified in a real PCB yet.) In this example all the pins on the footprint are mapped to pins on the symbol but it is just as easy to have some pins on the footprint labelled as not connects, for example, NC1, NC2 etc., or just all called NC. The important thing to remember is that the pin names on the symbol must match those on the footprint. It's OK if there are pins on the footprint that don't map onto corresponding pins on the symbol. * Another way is to make a schematic symbol that has all the package pins included. For example: `SQ3419EEV_TSOP6` in System Components. [1]: /editor/20170621/594990f52f52a.png [2]: /editor/20170621/59499139a6ada.png
