I am very new and am trying to layout a very simple schematic and sometimes I can’t get the symbol connection points to line up with the grid. Then it is impossible to wire the schematic. Here is an example.
If I rotate R4 it then lines up correctly. I cannot rotate Q1 to get anything but pin 3 to line up. Is this my system? This is the first time I have seen this. I did save the file and reload it, and tried to move the symbols hoping it would fix itself with a little magic. That didn’t work.
Generally we tell people to set it to 50 and leave it unless needed. All library symbols should align to that grid. Technically it is 50 mils but we like to think of it as unit less.
Set the grid to 50, select the entire schematic, right click and choose align to grid.
It looks like you have currently set a grid-size of 0,1"==100mil.
While I also prefer these grid size (in contrast to the standardd 50mil recommendation) some of the 2-pin and 3-pin symbols from the kicad standard library don’t work with this grid size.
So until you have gained some experience switch back to the 50mil-grid (View–>grid properties) and the connection-problems should be solved.
You could experience more grid-related problems in the future if you accidentally have the CTRL-key pressed down at unwanted times. The CTRL-key acts as modifier key and allows to place items (including symbols + wires) outside of the grid. This will again make the pins unavailable for connections. To correct such situations later you could use Right-Mouse Click (RMB)–>context menu–>Align elements to grid
