Several instances of each object exported

[pierre-nedelec]

Hi @adizanni ! thanks for your awesome work on this and the floor3d home assistant card. I have an issue when exporting from SweetHome3D with this: the obj and json contain several instances of each object in the layout, which leads to issues down the way (example: activating light is super hard because when you click on it it could be any of the instances...).

Have you encountered this before?

Example

{ 
 "wall_0_1" : { "object_id": "wall_0_1" },
 "wall_0_2" : { "object_id": "wall_0_2" },
 "wall_0_3" : { "object_id": "wall_0_3" },
 "wall_0_4" : { "object_id": "wall_0_4" },
 "wall_0_5" : { "object_id": "wall_0_5" },
 "wall_0_6" : { "object_id": "wall_0_6" },
 "wall_1_1" : { "object_id": "wall_1_1" },
 "wall_1_2" : { "object_id": "wall_1_2" },
 "wall_1_3" : { "object_id": "wall_1_3" },
 "wall_1_4" : { "object_id": "wall_1_4" },
 "wall_1_5" : { "object_id": "wall_1_5" },
 "wall_1_6" : { "object_id": "wall_1_6" },
 "wall_2_1" : { "object_id": "wall_2_1" },
 "wall_2_2" : { "object_id": "wall_2_2" },
 "wall_2_3" : { "object_id": "wall_2_3" },
 "wall_2_4" : { "object_id": "wall_2_4" },
 "wall_2_5" : { "object_id": "wall_2_5" },
 "wall_2_6" : { "object_id": "wall_2_6" },
 "wall_3_1" : { "object_id": "wall_3_1" },
 "wall_3_2" : { "object_id": "wall_3_2" },
 "wall_3_3" : { "object_id": "wall_3_3" },
 "wall_3_4" : { "object_id": "wall_3_4" },
 "wall_3_5" : { "object_id": "wall_3_5" },
 "wall_3_6" : { "object_id": "wall_3_6" },
 "room_0_1" : { "object_id": "room_0_1" },
 "Floor_uplight_1" : { "object_id": "Floor_uplight_1" },
 "Floor_uplight_2" : { "object_id": "Floor_uplight_2" },
 "Floor_uplight_3" : { "object_id": "Floor_uplight_3" },
 "Floor_uplight_4" : { "object_id": "Floor_uplight_4" },
 "Floor_uplight_5" : { "object_id": "Floor_uplight_5" },
 "Floor_uplight_6" : { "object_id": "Floor_uplight_6" },
 "Floor_uplight_7" : { "object_id": "Floor_uplight_7" },
 "Wall_uplight_1" : { "object_id": "Wall_uplight_1" },
 "Wall_uplight_2" : { "object_id": "Wall_uplight_2" },
 "Wall_uplight_3" : { "object_id": "Wall_uplight_3" },
 "Wall_uplight_4" : { "object_id": "Wall_uplight_4" },
 "Wall_uplight_5" : { "object_id": "Wall_uplight_5" }
}

Part of the .obj file:

Hello @pierre-nedelec , in reality what you see in the export it is not the same object but the components of the objects (for a lamp it can be the base, the cover, etc.).
If you want an object to group together all the components with a unique name you just append a '#' to the end of the object name in SweetHome. Try and let me know if it fits your needs
