If you want to adjust the pin spacing of PCB package, you can modify it directly in the package library (to open the library, find the corresponding component modification), or double-click this component and remove the check mark of the lock element in its properties, so you can edit the pins directly.

First of all, you should be clear whether you want to edit the schematic diagram or PCB. If it's a schematic diagram, it doesn't need to be drawn according to the size in the manual, which has no practical significance at all. The pins in PCB are not represented by wires. The drawing standard of PCB can be assembled without disturbing other components and must meet the requirements of production process.
