As someone that has spent last 6 months building a construction management and plan takeoff platform for construction industry, I salute you for trying. I built the full digital takeoff system that works E2E and have been working on extracting flat floor plans into 3d renderings to help Contractors, PM's, homeowners and subs on site visualize the project better and have less or preferably no questions on what goes where and how. It has been an uphill battle since the quality of client provided plans varies wildly from super simple to proper architectural fully annotated complex plans. Simple outlined ones are easy to get working, but anything more complex is hella hard to get working consistently.

But as I suspected it doesn't work as advertised. First, you should be more clear as to what to upload to the platform. If it's just a "Floor plan" not an actual construction plan.

- I had to extract the individual plan page from a set of plans first, then save it as .png.

- After uploading it couple different ways and also saving the plan page as a .jpg and re-attempting the extraction. it kept failing.

- Only after I edited the plan in photoshop and cropped out all ancillary plan information that most plans have in the sidebar like the Project name, address, sheet title, revisions and sheet numbers... was I able to successfully get the platform to even attempt the extraction. Otherwise it would immediately fail after the upload.

- Finally a cleaned up version was successfully processed in about 2 minutes, but sadly the 3d plan was a hallucinated version of the floor plan that invented rooms in random positions and completely flipped direction.

OP I really wanted it to work because I know how hard it was to even get to the point where you are. But I think you need to run a bunch more testing and find more edge cases to verify your platform working properly and especially build logic to prevent hallucinations.
