Edit PCBLib in the Libraries

When you found a PCB Libs(footprint) but it can not be satisfied for your design, you can edit it to be your personal PCB library.

Via Libraries > Type: PCB Lib > Search Component/Personal/LCSC/System > Select footprint > Edit

You can edit the pad size, shape outlines, etc. when you finish and save, it will be saved to your personal libraries “Created” and become your personal libraries.

And you can add a tag for your PCBLib when you save it:

Modify the saved PCBLib tag: Libraries > Type: PCB Lib > Personal > Select footprint > Right Click > Modify

About the tag suggest that using as below:
Through-Hole:
AXIAL: AXIAL-0.3 etc. RAD:Radial HEADER:Headers, connectors DIP:Dual-In-Line components SDIP:small dual in-line package SIP: single in-line package ZIP: zig-zag in-line package TO-92: Transistor Outline 92 TO-220: Transistor Outline 220
Gull-wing:
QFP,MQFP,PQFP: Quad Flat Pack TQFP:Thin Quad Flat Pack VQFP: Very Fine Quad Flat Pack PSOP: Plastic Small Outline Pack SOIC: Small Outline IC, narrow/wide VSSOP,SOIC: Miniature small Outline IC SOD123,SOD323,SOD523: Small Outline Diode SOT23,SOT223,SOT3X3,SOT523,SOT563: Small Outline Transistor TSOT,TSSOP: Thin Small Outline Package SSOP: Shrink Small Outline Package DFN,SON: Dual Flat No-lead QFN: Quad Flat No-lead TQFN: Thin Quad Flat No-lead
J-lead:
SOJ: Small Outline IC, J-lead PLCC: Plastic Leaded Chip Carrier JLCC: J-Lead Chio Carrier
Other:
SMD: Chip resister, Chip capacitor MELF: Metal Electrode Leadless

Edit PCBLib in the PCB

If you want to edit a package(footprint) in the PCB, you can use the Ungroup/Group function same as the schematic.

On the PCB Tools palette there is the Group/Ungroup Symbol… button.

This tool is for you to quickly create or edit library symbols.

  1. Select a package(footprint, PCBlib)

  2. Click the Group/Ungroup Symbol… button
    Up to this point you have a collection of separate pads, a drawn silk layer tracks and some text that are all separate items with no particular association with each other.

  3. Edit the shape or pad what you want to change

  4. Select all of the items and click the Group/Ungroup Symbol… button.

A dialog will be opened:

After you click OK, all those separate elements will be grouped together to form your new symbol directly in the PCB.

Using the group function, you can create/edit any symbol in the Schematic/PCB, easily and quickly.
