Thank you for your response. I checked the json code. Some of the part in json I understand but need your help me to understand a part in json code after saved. Can you advise us for this part:-

Anthony Hi! We would like to request a meet at your earliest convenience to discuss some important details, particularly regarding API and touch input. Your insights would be invaluable to us. Alternatively, if that is inconvenient, could you please provide documentation on API and touch input? We look forward to your response.

nabiela Hi, you can book a 30min with me using this link:
https://calendly.com/anthonylotte/one-on-one-with-anthony

We can talk about the json variables on the call directly then.

For the API documentation about Home Designer, I don't have any yet but for the touch library, it's based on Lean Touch, you can a documentation here:
https://carloswilkes.com/Documentation/LeanTouch

nabiela Hi! Can you describe what you don't understand from the json you posted? I will try to explain in more details.
As for the undo/redo there is no feature like that at the moment.

Anthony Hi, ⁠We already know a few attributes like types, name, width, height ect. We want to know about normalizedPositions. Is the x,y,z follow the base grid (Unity xyz position) or floorplan that we made? ⁠Can you clarify these attributes in json, magnitude and sqrMagnitude?!

also if you look at the video I included, you can see where the floor plan exceeds the line border, can I know why this can happen, please assist me

Anthony ⁠How do we change / rename the assets / furnitures, including the sizes, color, variant?

Anthony How to insert wall and floor materials in quotes?

nabiela Hi! Sorry for the late reply.
normalizedPositions are some local positions on the Grid object, I suggest to have a look at the grid.cs component to understand. it's just a way to have points on the grid, so that we can move/rotate/scale the grid and impact the all floor plan.
Don't worry about magnitude and sqrMagnitude, these are properties part of the Vector3 class that are being serialized in the json but they are not actually used, we just need the x,y,z values.

if the buliding goes out of the border, it means you had drawn the bulding too far, or you have changed the boundaries. just increase the size of the boundaries to your needs.
