Offset issue for 3D Model

[uPesy]

Hi,
I have not find the way to convert the offset of easyeda 3d model to KiCad 5.x

For exemple for ID C319148, here the JSON with only relevant data

"dataStr": {
                "head": {
                    "x": 4001.992,    // x origin footprint
                    "y": 2999.8101,  // y origin footprint
                },
                "canvas": "CA~1000~1000~#000000~yes~#FFFFFF~10~1000~1000~line~0.03937~mm~1~45~visible~0.5~4001.992~2999.8101~0~none",
                "shape": [
                    "SVGNODE~{\"gId\":\"g1_outline\",\"nodeName\":\"g\",\"nodeType\":1,\"layerid\":\"19\",\"attrs\":{\"c_width\":\"35.19678\",\"c_height\":\"31.1023\",\"c_rotation\":\"0,0,180\",\"z\":\"-3.5433\",\"c_origin\":\"4001.992,3004.2501\",\"uuid\":\"c50ce21ae3b941ce8eeb9bccc6cdef41\",\"c_etype\":\"outline3D\",\"id\":\"g1_outline\",\"title\":\"USB-3.1-SMD_16P-L8.9-W7.3-H3.3-P0.5\",\"layerid\":\"19\",\"transform\":\"scale(1) translate(0, 0)\"},\"childNodes\":[{\"gId\":\"g1_outline_line0\",\"nodeName\":\"polyline\",\"nodeType\":1,\"attrs\":{\"fill\":\"none\",\"id\":\"g1_outline_line0\",\"c_shapetype\":\"line\",\"points\":\""}}]}"
                ],

I don't know how to properly set the offset of all 3D model for x, y , z offset. Here some relevant information :
For example for the 3D model of LCSC ID C319148
API result : https://easyeda.com/api/products/C319148/components?version=6.4.19.5
Here the data for the 3D model :

Width of the model is c_width * 10 in mil.
Height of the model is c_height * 10 in mil.
The z offset is z * 10 in mil.
c_origin are the x, y origin of the 3D model, but i don't know relative to what ?
The bbox origin in the footprint is "x" and "y" key

At the end of JSON file sent by the API, there is a another BBox
"BBox": { "x": 3982.6, "y": 2987.6, "width": 38.7, "height": 33.3 }

In the code for now, it's the c_origin - footprint bbox, but it doesn't work:

easyeda2kicad.py/easyeda2kicad/kicad/export_kicad_footprint.py

Lines 204 to 211 in 6325431

	ki_3d_model_info = Ki3dModel(
	name=self.input.model_3d.name,
	translation=Ki3dModelBase(
	x=round((self.input.model_3d.translation.x - self.input.bbox.x), 2),
	y=-round(
	(self.input.model_3d.translation.y - self.input.bbox.y), 2
	),
	z=-round(self.input.model_3d.translation.z, 2),

Some kind of formula should be found between "c_origin", "x" and "y" footprint bbox, c_width and c_height , and maybe with the other "BBox" key too.

I try to look the code on EasyEDA, it's React production code, to find the formula. I found this, but i have not managed to get relevant offset :
In line 87700 of main.min.js :

Your help is really appreciated:)

Note that in the end, the dimensions should be converted in mm for Kicad

I'll take a look, probably this week, very busy at the moment ....
