I'm quickly knocking together a PCB for a simple helper tool. And when I came to lay out the PCB itself I realised the order of connections between two components needed to be reversed. So I went back to the schematic and impatiently made the change you see in the picture.

It works, and this is a schematic I'll almost certainly never look at again after the boards are ordered, let alone share.

The OCD in me tells me to fix this. But the artist in me kinda likes it. What do you think?

It looks like the schematic of my brain.

Does the CAD let you just turn the resistor network over? (CAD limitations like that are one of the reasons I still do my schematics by hand.)

Edit, just to add something without doing another post: Quite often, in order to make the schematic more clear and easy to look at by straightening out the connecting lines and reducing the number of elbows in them, I want to change the order of, or spacing between, pins around an IC in the schematic. Schematic-capture software generally won't let you do that without making it a new schematic component.

In Kicad you just press X or Y to flip a component in an axis. I always press the wrong one first though!

I won't mention the hassles of trying to read a schematic in color. :( It looks as though some connections are missing.

I JUST learned that yesterday btw, super handy, better than trying to rotate everything!

Dammit! I didn’t know that. Would have been so much easier.

[Edit] Just tried it, and it worked a treat, although I think the KiCad devs have the use of X and Y backwards. Y seems to flip in the horizontal axis, which I think of as the X axis. But no matter - it does the job, although the schematic is significantly more boring now.

Perhaps the keys refer to the axis of flipping/reflecting, rather than what is being flipped/reflected. If you flip across the Y axis, you're reversing the X values. If you flip across the X axis, you're reversing the Y values.

Being a math teacher, this conversation is hilarious!

One of my beefs with KiCad is it's relatively poor documentation, which is why I haven't done much with it. KiCad reflects the mantra of software developers: "Programmers write code, not prose."

They have just released Kicad 6, which apparently makes the schematic editor behave more like the PCB editor - so this has probably changed now.

I haven't tried it yet... Relearning is hard!

At age 16 my brain was super-efficient, and I could tackle new subjects and juggle them with ease. At age 56, uhh, not so much.

I've just downloaded it. I've only played with the new version briefly, but it does seem like they're improved the UI somewhat. For example, on my Mac I can now click & drag symbols without having to press M first. Also, dragging a footprint in the PCB editor also drags attached tracks. And I think they've changed the logic of the X & Y commands in the schematic editor – so maybe they heard me!

Like I say, I've only played with it briefly, but as software UX goes I think they've definitely managed to propel KiCad into the late 1990s – which is an improvement.
