I have the same issue. Despite the fact that there is no documentation on the object that has to be passed to `insertShape` / `createShape`, all the examples using them just do nothing at all :(

Hello, the pcb json object contains several objects and more particularly SIGNALS and TRACK. `var pcb = api('getSource', {type:'json'});` How to add a track ? First, create an arbitrary  "gId" like "myTrack" as it MUST be unique. Then, add this object  into the SIGNAL object : `pcb.SIGNALS.<your net name>.push({` `"gId": "<your gId>",` `"cmd": "TRACK",` `"layerid":1,  // <-- to be aligned with your PAD layer` `"fid": 0 // <-- set  this to zero` `})` Ok, now let add your real TRACK : `pcb.TRACK.<your gId>= {` `"gId": "<your gId>",` `"layerid": "1", //<-- MUST be aligned with your PAD layer` `"net": "R_D0",` `"pointArr": [` `{` `"x": 4373.752, //<-- x start point` `"y": 2990.835`    // <-- y start point `},` `{` `"x": 4373.752, //<-- end of the wire` `"y": 3100`    //<-- end of the wire `}]` `}` Then, repeat {x,y] tuples in the pointAddr as long as you need to add vectors. Do not forget to update your pcb with : `api('applySource', {source: pcb, createNew: !true});`<br> <br> This works for me. Feel free to give me some feedbacks I'm not sure how to generate the gId... Cheers

@VercorsSciences you are right, you can add tracks by editing the project source (json) via the API. I also used this in a project here: [https://github.com/xsrf/easyeda-svg-import/](https://github.com/xsrf/easyeda-svg-import/blob/617e2032aaf45f84e93857bd65f7de0423ac6f38/extension/main.js#L431) The gId generator is (afaik) not accessible for an extension, but you can generate your own IDs. Didn't find any problems with that so far. I use this: ``` js function newId() { return "cgge"+Math.floor(Math.random() * 9e6); } ``` Better way would be to use incrementing IDs with your own prefix, but you'll need to keep track of them.

Also, instead of editing the project source, the `createShape` API can be used ``` js api('createShape',{ shapeType:'TRACK', "jsonCache": { gId: "gge"+Math.floor(Math.random() * 9e6), // optional layerid: "1", pointArr: points // as described by VercorsSciences } }); ``` In this case the gId attribute is actually optional... a new one will be created. But I don't know how to reference it in case you need it afterwards... api() won't return the id.

Thanks, I just noticed there was some discussion here.  I was able to successfully create a track from your suggestions using this... ``` api('createShape',{ shapeType:'TRACK', "jsonCache": {         "layerid":1, pointArr: [{ "x": 0, "y": 0 }, { "x": 10, "y": 0 }, { "x": 10, "y": 10 }, { "x": 20, "y": 10 }] } }); ```  The only problem I have is that the location is not at around 0,0 but is ending up at about -1000,900.  I know in some of my other scripts, I'm converting from mm to mil even though my canvas is set to mm.  But that would still be centered at 0,0.  Not sure why these coordinates are ending up so far away.  I'll keep looking but if anyone has any thoughts there, that would be helpful.

@BillyBuerger the coordinates used by the api are always in absolute relation to the canvas (not the origin) and the unit is always 1/100 Inch. You can query the origin coordinates via `api('getSource',{type:'json'}).canvas.originX` and `api('getSource',{type:'json'}).canvas.originY` and translate your tracks coordinates accordingly.

Alternative for getting canvas attributes (might be faster than querying the source, not sure): `api('editorCall','getCanvas')`

Thank you so much.  This is now working as expected... ``` // Get the origin of the canvas var can = api('editorCall','getCanvas'); var x = can.originX; var y = can.originY; // convert mm to 100th of an inch var off = 10/0.254 // Create the track api('createShape', {     shapeType:'TRACK',     "jsonCache": {         "layerid":1,         pointArr: [             {"x":x, "y":y},             {"x":x+off, "y":y},             {"x":x+off, "y":y+off},             {"x":x+2*off, "y":y+off}         ]     } }); ```
