I have to confess I cheated.
I drew a fill block on the floor plan and saved it as a object.
I created it at the origin to a known size (600×600) using a fill geometry ‘linked to the fill origin.
I then selected it and saved it as an object, opened the object and edited the 2D script.
I can go into more detail if that would help but I’m not sure how much you know.
Let me know if you need more guidance.
Hope this helps
