Freeze the measured room, not an attractive preset
This workflow is for dorm residents, renters and household planners deciding how one rectangular room could be arranged. Record interior clear width, depth and height, openings and furniture dimensions with measurement date and uncertainty. Include handles and moving parts in site notes. A preset is a starting example, not a survey. Keep the original values before converting lengths; area conversion uses squared units and cannot establish circulation space.
Inspect a usable arrangement
Enter exact dimensions, add doors and windows, and compare the floor plan with the 3D view. The planner models inward 90-degree doors; real hinges and opening directions must be checked separately. Look for overlaps and out-of-room objects, but also inspect chair pull-out, drawers, wardrobe doors and access to windows. Approximate warnings are prompts, not building-code, accessibility or fire-safety approval.
Check the actual room and furniture before buying or moving. A piece fitting its final footprint says nothing about whether it passes the building entrance, stairs, lift or hallway turn. Record those delivery checks separately rather than inventing a standard clearance threshold.
Keep revisions and exports consistent
Save baseline and proposed JSON before making further changes. Compare room sizes, item dimensions, positions, rotation and openings. Explain intentional differences instead of approving only a nicer view. Unit-display changes may not mean physical dimensions changed; inspect what the exported fields represent.
Export JSON, furniture CSV and SVG from the same selected revision. CSV validation checks quoting and row structure, not spatial correctness. Manually reconcile row count, names, width, depth, height, position and rotation. CSV lengths use the selected display unit and are rounded; the editable model is not reconstructed reliably by treating CSV as complete JSON. Room and opening data are not all in the furniture list.
Review copies without assuming print scale
Keep SVG as the floor-plan source. Use PDF for a review document or PNG when a raster copy with explicit resolution is needed; the planner already offers image export, so extra conversion is optional. Inspect the actual result for missing labels, font changes, clipping and line legibility. Conversion may use server processing even though planning is local.
The exported SVG uses a pixel-based view size; it is not a certified physical print scale. Fit-to-page, margins and printer settings can change size. If a scaled print is needed, independently calibrate a known dimension on the final paper, record settings and label unverified copies as not to scale. Do not infer site dimensions from a screenshot or perspective view.
Hand off one identifiable decision
After the last change, hash JSON, CSV, SVG and selected review copies. Include revision, measurement ledger, comparison notes, unresolved warnings, reviewer and on-site tasks. Hashes identify bytes, not measurement accuracy. Keep sensitive address details in a controlled local record and obtain permission before uploading files to helpers.
Use the unit-conversion workflow for broader dimensional questions and print preparation for assembling review documents; general file comparison can support other formats. None replaces remeasurement, real furniture operation checks or delivery-route inspection. The outcome is a documented arrangement for discussion and move-in preparation, not permission for construction.
