A practical guide
Trace a floor plan into an editable 3D room
A property listing or architectural sketch can be a useful starting point for a room model, but an image alone does not establish an accurate scale. Rumblespace provides a guided workflow: upload the plan, identify one known length, and trace the inside boundaries of the rooms. The resulting layout can be furnished, edited, and explored in three dimensions.
Choose a clear image of the floor plan
The tracing tool accepts PNG, JPEG, and WebP images up to 15 MB. Use an image that shows the complete rooms you want to model, preferably viewed straight on. A screenshot of a floor-plan page works, but crop away unnecessary browser controls and surrounding content before importing it. For a PDF, export the relevant page as an image or capture a clear screenshot. The current tool does not parse a PDF directly or identify walls automatically.
A high-resolution image helps you distinguish the inside face of a wall from its outer edge. Photographs taken at an angle can distort different parts of the drawing, so a single scale measurement may not be accurate everywhere. Correct the perspective or find a flatter source image when possible. If a plan is schematic, stretched, or marked not to scale, use its written dimensions as a guide and verify the important room measurements independently.
Calibrate the plan from one known measurement
Open Trace a floor-plan image and choose your file. In the calibration step, click the two ends of a clearly identified wall or dimension line. Enter the actual distance between those points, including units, then apply the scale. The selected length becomes the conversion between image pixels and physical dimensions. Pick a reasonably long, unambiguous measurement so a small error in your click position has less effect on the resulting model.
Feet and inches, metric values, and supported fractional expressions can be used for calibration. For example, a known wall might be 12′ 6″ or 3.8 m long. Be careful to use the same endpoints represented by the printed dimension: a measurement across the outside of two walls should not be assigned to an inside opening. If a second known distance looks wrong after tracing, recalibrate or investigate whether the source image was resized unevenly.
Trace one room at a time
Click the room’s corners in sequence, following the inside wall edges. Give the room a meaningful name, then click the first corner again or use Close room to finish the outline. The preview shows the traced area at the calibrated scale. A room must form a valid outline without crossing walls. If you place a point incorrectly, step back before closing, or edit the completed outline from the list of traced rooms.
Use the zoom controls when a corner is difficult to locate and Pan when you need to move the image. Nearby corners can snap together, and edges close to horizontal or vertical can align as you trace. These aids help produce a usable model without demanding pixel-perfect input. They do not correct an inaccurate source plan. Keep checking that the traced boundary follows the room you intend to build, especially around recesses, stair enclosures, and narrow passages.
Connect adjacent rooms deliberately
Trace additional rooms before creating the layout if you want a walkthrough that includes several spaces. For adjoining rooms, place the shared boundary on the same line and use matching corners where possible. Rumblespace models room boundaries as shared wall lines, so tracing both faces of a thick wall with a gap between them does not automatically establish a connected doorway. Decide on a consistent shared line while preserving the inside dimensions that matter most to your furniture plan.
After creating the layout, select a room and add a door or open doorway to its shared wall. When another traced room occupies the matching side of that wall, the planner creates the corresponding opening so the passage is clear from both rooms. Openings can be moved along their walls and resized. A doorway leading to unmodeled space uses a colored placeholder instead. This lets you build only the part of the home that is relevant to the current planning task.
Turn the traced outline into a useful walkthrough
Creating the traced layout replaces the current arrangement with the rooms you reviewed. Existing furniture and openings are not guessed from the image; add them after the rooms are created. The action can be reversed with Undo. The imported image remains available as a calibrated reference in Plan view, and you can hide it when the room outlines are easier to read on their own. Editing a room does not stretch the original image to conceal a dimensional mismatch.
Add furniture using templates, actual product dimensions, or the automatic furnishing option for a selected room. Set the ceiling height and choose wall and floor finishes to make the space easier to recognize. Switch to Dollhouse for an overview, then Walk inside for an eye-level view. The traced image supplies a starting outline, while the editable model lets you explore alternatives that are not shown on the original drawing.
Save the model and understand its limits
Your image is processed in the browser and stored as a compressed reference when you save the project. Download a project file if you want a lasting copy, then reopen it to continue editing. The current browser tab can retain the working model, but it is not a synchronized account or cloud archive. Avoid relying on a single open tab for a plan that took time to trace, particularly before changing devices or clearing browser storage.
This workflow creates an editable visual model through guided tracing. It is not automatic architectural recognition, a measured building survey, or a guaranteed reproduction of every detail in the source. Use the bedroom planner for bed-size comparisons, the furniture-fit tool for actual furniture footprints, and the attic planner for sloped ceilings. Before ordering fitted furniture or building anything from the model, check the critical lengths, heights, and openings at the property itself.
