Hello, EasyEDA does not have automatic component alignment on the PCB. I spent 3 days aligning my components with a spacing of 18.260 millimeters. Now, after I made changes to the schematic, I clicked "Update PCB," and the schematic removed all the components, meaning I will have to redo everything from scratch. How can I update the PCB while keeping all the existing components on the board? I tried locking the components, but it didn’t work... During the update, the software still removes all the components.
