I am having a? problem with laying out a
simple PCB, using version 8.01 under Widows 11. The problem is
that even resistors and capacitors have specified ends, and it
seems impossible to overcome this. For example, I have two
capacitors to be connected in parallel to make up a non-standard
value. KiCad insists on connecting the north end of C1 to the
south end of C2, so the other connection C1S to C2N cannot be
made. I see that it's not possible to directly invert a
footprint, and applying? a 90 degree turn twice doesn't fix the
problem.?
I can't find anything about this in 'Getting
Started' or the 'English Documentation', but of course it might
be in there somewhere. Please advise.

Are you trying to place a copper track from the end of one capacitor to
another and KiCad won't let you make that connection?
KiCad will only allow you to make connections between components that
are described in the schematic you have entered. So if your schematic
says the connections have to be made one way, and you try and do it
another way, it won't let you.
You can turn on the Ratsnest function in the PCB editor which will show
you the connections KiCad wants to make between components, driven by
what you put in the schematic. That should help you see what is going on.

Hi
Yes.
Also when I come across this issue when routing a PCB, I go back to the schematic and rotate the component there.
regards
Jorge

Thanks. I can't try it now, but I expect it
will work. I guess it's needed for the schematic to work in
simulation. But It's something that I would expect to be
mentioned in 'Getting Started', because it's really quite
fundamental to laying out a PCB.

just turning twice always works. Try again, you must have made a
mistake.

Hi
Back in the day, when I was a Kicad rookie, I found this quite
natural.
Pins are numbered in schematic symbols and also in PCB
footprints, and naturally the symbols and footprints numbers must
match.
Its just the symmetric non polarized components that can get you
in this situation. But those cases are only a handful of
components; the vast majority of electronics components have
strict connection rules.
You can familiarize yourself with this and other details if you
invest some time just browsing a few components with the symbol
and footprint editors. You will also get a feeling for how ERC
rules work.
Best regards
Jorge

This is exactly the behavior you want. (Think about electrolytic caps)
Put he mouse pointer over the component then press R a couple of times to rotate the footprint.
That should untangle the rats nest.

Another thing to note. Remember to check the right !lick context menu you should find all sorts of footprint movement options there.

Thanks, but I don't understand 'right !lick'.
If it is 'right click', I still don't know what to click on.

Ki cad has lots of command options, many of these care accessable when yob right click the mouse while an object is selected?
Usually just hovering the mouse pointer over the object is enough to select it.??
