Disaster recovery?
开云体育I asked KiCad to renumber the components on the schematic. What I didn't realise is that it turns the PCB into a disaster area, because many of the components are then in the wrong places, with wrong connections. Is there a way to recover from this, or do I have to delete all the components and tracks and start again?? Is there a way to prevent the disaster, other than not renumbering? I have another question: is there a way of
printing the list of keyboard shortcuts? Since it is an HTML
page in the on-line manual, I can't see how to do it. --

Re: Footprint without schematic symbol
开云体育Thanks, Andy. Yes, that's what I should be
doing, but it's a big job to get started on. I'm trying to
appease the alligators, before draining he swamp. On 2024-05-23 10:24, Andy wrote:
SW_DP3T looks something like what you are asking form it's in the switch lib. Get used to making your own footprints and symbols it's one of the most useful things you can do as it's a great time saver. The way to go is find a symbol (or footprint) that's close, copy it, rename and save in your own libs which you should be doing anyway, and it's not a good idea to use the provided libs directly as you have no way of knowing if an update has changed something. It's should not, bit it can happen.

Re: Problemsending data from schematic to PCB
开云体育Yes, that was the problem, but the
designations need to show in order to put the components in
their places. On 2024-05-18 21:53, Andy wrote:
I agree that this just sounds like the layers are switched off usually on the right hand side of the window there is a panel with some tabs Layers Objects Nets Select layers and make sure there is an eye symbol and not a stop symbol. It's quite common to turn off the silkscreen and other layers as they can cause a lot of mess on screen when you are trying to lay out a board.

Re: Power flag problem
开云体育You can place a PWR_FLAG symbol on the relevant net. You can find this in symbol folder called "Power". Usually, GND also needs one.-- Regards,

Re: Power flag problem
开云体育Thank you. My problem cam from opening the
power symbol list by clicking on the 'earth/ground' icon. The
list that opened did not show the PWR_FLG symbol, but later it
appeared. I suppose the list did not fully load. On 2024-05-18 13:19, Robert via

Re: DB15 connector symbol
开云体育Indeed. For some reason, they all got to be
called 'DB', perhaps because the 25-contact size shell was so
widely used. And before the high-density range was introduced,
the pin-count and shell-size were 1-to -1 matched. On 2024-05-17 21:28, Donald H Locker

开云体育Is there anywhere a symbol for the DB15
15-contact connector? I know that I could make one, but its
geometry is not simple. --
