Kicad. From Software To Hardware Part3

We have all basic instruments to do the job.
First of all set the grid to 5 mils, good resolution to design; in facts confronting with original relay_2rt (you can load it into EESchema to have a model) and setting the resolution to the above one, you'll see the correct distances and lengths.
kicad-relay-rectangleFirst the rectangle of inductor: you can indifferently use the forth or the seventh palette icon; usually with a rectangle you delimit the symbolic component body, but it's not a rigid rule.
Being close to model we trace 10 steps horizontally and 40 vertically.

Little trick 1: click on a point with your tool selected and then move with keyboard's arrows.
Little trick 2:
to get a crossed reference, choose last icon on left palette (Change cursor shape).

Choosing the forth you simply click-drop-click; with the seventh click-drop-doubleclick.

kicad-pins-positionedClick on the second to add pins; on first picture beside only pin number is set.
Press OK and put it where you want; or the pin-8 eight steps down from rectangle's top and eight left, while pin-9 twelve from bottom and eight left.
Result must be like beside.

Remaining job is intuitive and simple; just use line or arc tools where needed.
Note that arcs are designed while original model has 3 lines; not so important, as previously said.
Following pictures show how to complete the inductor's symbol.

kicad-output-pinkicad-myrelay-completeInductor's symbol is complete; let's start with the switching part.
Triangles and lines are now simple draw; after add new 3 pins: number 5 as previous ones, 1 and 3 are little different, just for their left orientation instead of right.

Final job must be like on right picture.
