I am back to creating BuildElectronicCircuit’s 3-part demo PCB at https://www.youtube.com/watch?reload=9&v=l9b_6WLemmg
It’s a simple through-hole board–as simple as you can get, 3 parts, 3 wires.
I successfully recreated the schematic and net-list.
I read the net-list from pcbnew (successfully I think, because when I opened the PCB file, I saw three components laid on the black screen and connected on the bottom Cu with green traces.
However, problems occurred when I moved some components–footprints, rather–to get a better lay-out. Two of the green traces turned white (in the middle of the trace). The green trace that was completely horizontal turned white on the right with the left part green but hanging off vertically! And the trace that was at a diagonal angle stayed intact but changed from green to hatched white/gray/.
Should I have
[ 1. ripped up the old traces, 2. moved the parts I wanted moved, and 3. re-routed the traces ] instead of doing what I did–assuming the green traces would stretch and move along with the components as I moved them?
Is there a button or menu option in pcbnew that rips up all existing traces?
