I have designed my first PCB. I thought I know enough to faster or slower do what i wont, but I see I was wrong.
PCB was waiting few days. After that I wonted to make gerbers and order it. But before it I run DRC and found all my vias from via stitching lost their connection to GND. So I ordered that PCB without DRC (no time to wait till I will know what to do).
These vias are defined by me footprints (I read here how to do via stitching). Some time passed before I get an idea that I probably done everything right except I didn’t locked my vias, or may be I locked their pad and not the whole footprint (at that moment I don’t know what is enough to be good). There are not a lot of them (simple, small PCB) so I assumed: what I need is only to give each of them GND net and lock - should not take a lot of time. And zonk - I can’t find the way how to do it.
Right mouse click suggests E.
But E opens:
certainly not a place to set GND and lock.
I remember the lesson from my previous question - if you think somesting should be possible and is not use F9. After F9:
I have locked someting. But not sure if pad or the whole footprint. Don’t know how to check it. For devices with few pads I cen poin pad or device. Here I don’t know what I am pointing.
But still don’t know how to set GND. From the above picture I see that E will change Via size. But from ? help I see (last line)
that E will allow me to Edit my via.
I tried E and it made my via smaller (no questions asked). I am surprised as it was not via made during routing but it was defined by me footprint. Did he changed footprint to another (I have 5 different size vias in my library). I don’t know the rule acoording to what that E changes the via size. Trying to use it once more gives me no next changes.
- How to lock it to be sure if I locked pad or whole via footprint?
- How to set thats via (or may be rather its one pad) net to be GND?
- What are the rules used by E to change via size?
