Programmatically Place a Footprint and Generating PCB files

I would like to repeatly place a footprint to specific coordinate with codes. Refers to the document, [https://docs.easyeda.com/en/DocumentFormat/3-EasyEDA-PCB-File-Format/index.html#Footprint](https://docs.easyeda.com/en/DocumentFormat/3-EasyEDA-PCB-File-Format/index.html#Footprint)<br> <br> Footprint have these parametes, **configure** ```LIB~245~240~package`CK17-B`~0~~gge15~1``` 1. command: LIB 2. position x: 245 3. position y: 240 However, if I modified the position, it only changes the footprint origin, but the drawn shapes remains the same. Here is an example footprint I would like to put it **repeatly in specific x, y coordinates and rotation angle**. This is a keyboard's key's footprint. ``` "LIB~0~-4.77~package`~0~~gge1095~1~~~0~~none~~#@$TEXT~N~0~-47.5~0.7~0~0~3~~4.5~PG1353~M 4.5475e-13 -52.04 L 4.5475e-13 -47.75 M 4.5475e-13 -52.04 L 1.84

I can't help you with scripting this but you may find that the "Distribute Array" tool does what you want anyway: [https://docs.easyeda.com/en/Introduction/Basic-Skill/index.html#Align](https://docs.easyeda.com/en/Introduction/Basic-Skill/index.html#Align)

A long time ago I did this for a project using javascript (macro). Here's some of the code which placed items, [code] var x = posXY\[j\]\[0\]\*100/25\.4; var y = posXY\[j\]\[1\]\*100/25\.4; var ang = posXY\[j\]\[2\]; var id = LEDs\[LEDnumber\]\[1\]; api('moveObjsTo', {objs:[{gId:id}], x:circleCX+x,y:circleCY-y}); shape=api('getShape',{id:id}); var cur=parseInt(shape.head.rotation); if(isNaN(cur)){ cur=0; } ang=-(ang-cur); api('rotate', {ids:[id],degree:ang}); [/code] I can't post more as it was proprietry and I can't post the whole thing. Good luck, Note, one thing I realised was the rotation is relative to the previous rotation (hence ang=-(ang-cur);) - there may be a set absolute rotation but I couldn't find it. And, don't bother asking here as "No reply" is the normal answer.
