Well, that's the best shot after two days spent working on this task.
A new ASG plugin and its Eclipse project .

My vision is to create a plugin with three functions.
I’ve done 1% of the work; you’ll have to do the rest.
If there’s anything you don’t understand or if you need help, just ask.

PS: I've added two classes ExportItems and AddItems useful to add furniture to the home plan.
