Section (2.3) in section (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) explains how to do that.

To clarify: In the document (2.3) above, the sub section on: **Creating symbols for multi-part devices using Sub Parts.** describes sub-parts for parts like 7400 logic gates, V2164 VCA and TL074 op amps that have several devices in the same package. What it does not make very clear is that the devices do not all have to be the same or even be distinctly separate devices: they could just be separate sections of the same device. These devices or parts of a device however do have to be in the same package. For the document shows how the 4 switches in the CD4016BM can be split into 4 switch gate subparts plus a fifth subpart just for the power supply pins that are common to each switch gate. Another example is my Spice Symbol for the V2164:  Devices with large pin counts like microcontrollers can also be split up that way to help with schematic clarity. The symbol can be split up anyhow you like: by power supply pins and i/o pins; by i/o ports; by interface functions. As long as it is built to start with as described in (2.3) then the symbols in each sub-part can be edited to represent your choice of what you want each subpart to represent.
