There are times when I would like to put some temporary non-copper traces on my PCB to help with placement, or mark temporary keepout areas that I will remove once I don’t need them anymore.
I tried using a variety of trace types and layers (eg fab) but I would get the “not on copper layers” error message.
I have resorted to using top and bottom copper traces, but this is not a satisfying solution. I cannot run traces that intersect, which means I need to remove my registration traces before I am done with them.
Why not use the normal graphical tool that is intended to be used for technical layers? (What would be the benefit of using traces instead of normal lines?)
