Apartment Plans – 2D and 3D – Made Easy with AdPlan

Apartment plans—both 2D floor plans and 3D models—are crucial for interior design, real estate sales, and renovation planning. Until now, creating such technical architectural drawings required manual drafting or using online programs (e.g., Archiplaner.pl), which was time-consuming. Now, thanks to LiDAR technology in iPhones and the AdPlan application, you can quickly and easily scan an entire apartment and receive a ready-made digital layout of rooms—complete with dimensions and a spatial visualization—in literally just a few minutes. What’s more, AdPlan automatically creates an accurate apartment floor plan without the need to draw from scratch, eliminating measurement errors and allowing you to immediately use the data for design arrangements or property valuation. Below, we provide a step-by-step guide on how to plan your layout using AdPlan—from preparation, through the 3-minute scan, to exporting the results.

Note: The phrase “in 3 minutes” refers to scanning a typical single room or a small apartment. Larger apartments and single-family homes will take proportionally more time (e.g., a full house measurement might take ~10 minutes), but it will still be quick and easy compared to traditionally drawing a plan from scratch.

Apartment Floor Plan Online – What to Prepare Before Starting To ensure a smooth apartment scan, it’s worth preparing a few things beforehand:

• Phone and App: Make sure your LiDAR-equipped iPhone (e.g., Pro models from iPhone 12 onwards) is charged, and the AdPlan app is installed and launched. In the app menu, select LiDAR scanning mode.
• Space: Clear the apartment of obstacles that hinder movement around the rooms—open doors, move larger furniture away from walls (if possible) to ensure access to all corners. LiDAR needs to “see” wall outlines, so access to corners and recesses is crucial for fully capturing room geometry.
• Action Plan: Quickly walk through the apartment and plan your scanning route. You will need to walk around each room along the walls—start in one room and move systematically, slowing down at corners and doorways so the scanner accurately registers them. This allows the application to correctly detect characteristic points (angles, edges) and reconstruct the full outline of the apartment.

The 3-Minute Process of Creating Apartment Plans – From Scan to Plan LiDAR scanning continuously reconstructs the geometry of a room, automatically creating a digital model. The AdPlan application uses the iPhone’s laser scanner (LiDAR) to measure the room in real-time and build its model. An average scan of a multi-room apartment takes just a few minutes—as shown in the tutorial, scanning two rooms takes about 5 minutes. Below are the steps of this process:

Scanning the Perimeter and Walls (Automatic Geometry Detection) Start the LiDAR scan by pointing the phone at the floor and walls of the room. Walk around the interior perimeter, holding the device steadily. As you move, AdPlan automatically detects walls, corners, and other architectural elements—continuously creating a complete floor plan on the screen. You don’t need to sketch anything manually—the app draws the room outline itself. Thanks to built-in intelligence, even details such as window and door openings, recesses, and pillars are recognized (the phone registers these objects during the scan). The result is a 2D apartment plan outline that reflects the actual layout of all walls (both load-bearing and partition walls). During scanning, try to move smoothly; at key points—e.g., corners or near larger furniture—slow down to give the LiDAR time to fully map the surroundings. After walking the entire perimeter of a room, you will get a closed room contour. The application will also automatically recognize transitions between rooms (doors) and can start scanning the next room if it is connected to the first.

Adding Height and Openings (Doors/Windows) and Room Names Once you finish scanning the floor outline and walls, AdPlan may ask you to define the room height. On LiDAR-equipped devices, just one tap is enough to measure the ceiling height—the laser scanner precisely determines wall height. This is important for generating a correct 3D model. The application should automatically mark the position of doors and windows in the floor plan (if LiDAR detected them during the scan). If necessary, you can manually add or correct openings—e.g., if a window was obscured and not captured, you can quickly insert it in the appropriate place on the plan. At this stage, it’s also worth naming individual rooms on the plan (e.g., kitchen, bedroom, bathroom), which will facilitate later orientation, especially with a larger number of rooms. AdPlan automatically divides the space into separate rooms—it detects partition walls and assigns room names if you provide them. You can also view wall elevations (vertical projections)—the application generates not only a horizontal plan but also a wall layout with marked openings, allowing you to verify, for example, the heights of windows or doors in individual rooms.

2D Floor Plan and 3D Model Preview, Verification, and Point Correction After collecting all data, the application automatically creates a full 2D floor plan and a 3D model of your apartment. On the screen, you will see a traditional 2D technical drawing with dimensions (wall lengths, room areas, etc.) and you can switch to a three-dimensional model view—a ready visualization of the interior from a spatial perspective. Carefully review these results. Verify the dimensions—AdPlan automatically calculates, among other things, the perimeter of each room, the floor area (square footage), and the height and area of the walls. Compare the values obtained with documentation (if you have it) or perform one control measurement (e.g., measure the length of one wall with a tape measure) and compare it with the value on the plan. This reference check will help ensure that the scan accurately reflects the scale—if necessary, you can make minor point corrections in the application, such as moving a marked wall corner by a few centimeters. Generally, however, this is not necessary—LiDAR measurements are highly precise (around ±1 cm error), meaning you get an accurate floor plan of your apartment without painstakingly measuring every wall. If you notice a missing element (e.g., a small window wasn’t marked) or a minor inaccuracy, use AdPlan’s manual mode with automatic corners—it allows you to quickly adjust the wall layout and add missing corners/segments while maintaining precision. After verification, you can be sure that your digital plan reflects reality—both in terms of room shape and dimensioning.

Multi-Storey and Irregular Shapes What about measuring multiple storeys or irregularly shaped rooms? AdPlan handles these too. The application supports multi-floor mode—you can add successive project floors and scan, for example, the ground floor and then the first floor of a house within one consistent plan. After scanning the first floor, the user selects the option to add the next floor plan and similarly performs the scan on the next storey. The program then allows seamless switching between floor plans, which is useful, for example, for a developer presenting the layout of multi-level apartments and homes. As for irregular shapes—e.g., rooms with sloped ceilings, rounded walls, or pillars—3D scanning also works perfectly. LiDAR records surfaces of any shape (floors, walls, ceilings, even arches and slopes), ensuring that the resulting model will be faithful to the actual layout. In more challenging conditions (e.g., an attic apartment with roof slopes), it’s worth remembering to perform wall scans at several height cross-sections: AdPlan typically measures the outline at floor level, but you can additionally point the camera higher to capture changes in wall shape at ceiling height. The application can also handle the presence of furniture or built-ins—AdPlan 3D algorithms can filter such objects and focus on permanent structural elements. As shown in the video, the system even recognizes obstacles in the room (e.g., large wardrobes, air conditioners) and allows you to set reference points for precision. As a result, even non-standard rooms will be rendered faithfully and technically correctly, and you will get a plan that takes into account all bends and angles present in reality.

Export and Sharing Plans Once your 2D/3D apartment plan is ready and verified, it’s time to use it. AdPlan allows you to export plans in several formats, meeting various recipient needs:

• PDF: Useful for sharing the floor plan with clients or including it in a property listing. The PDF file contains a clear technical drawing with dimensions and room descriptions, ideal for non-industry individuals (e.g., apartment buyers, property managers).
• DXF/DWG (CAD): A format for further design work. You can easily transfer the apartment plan to AutoCAD or other CAD software. AdPlan generates a file compatible with popular applications for architects and designers. This allows an architect to use the obtained plan as a basis for creating a renovation or arrangement project—without the need to redraw everything from scratch.
• OBJ/DAE (3D): A 3D model format that you can open in SketchUp, Blender, or other 3D graphics programs. This is an excellent option if you want to create 3D visualizations—e.g., to present a fully furnished interior or perform a test placement of furniture in the model. Just import the OBJ/DAE file into your favorite interior design tool, and you can place furnishings, change finishing materials, and visualize different space arrangement concepts.

You can generate exports in the application with a few clicks—you choose the format, and AdPlan creates a file that you can save to the cloud or send. Sharing plans is very simple: you can send the ready PDF or CAD file via email, messenger (Messenger, WhatsApp, etc.), or share it on a network drive for colleagues. All projects are also stored in the cloud as part of your AdPlan account, so you and your team have online access to them from anywhere. You can work concurrently on multiple devices—e.g., an architect can edit further project details on a computer while an investor views the plan on a phone. Cloud integration and support for standard formats mean AdPlan seamlessly integrates with the existing workflows of design offices, real estate agencies, or construction companies.

It’s worth noting that unlike some free online tools, AdPlan provides professional results without watermarks. For comparison, while you can draw an apartment plan in the free online version of Archiplaner, the exported image will be marked with a logo (watermark)—only the paid version allows you to download the file without this mark. AdPlan immediately generates a clean, accurate technical drawing ready for commercial use, increasing the credibility of your documentation and presentations.

Best Practices for High Accuracy Finally, here are some tips to ensure your 2D and 3D floor plan is as accurate and architecturally correct as possible:

• Reference Dimension: Although AdPlan calculates all dimensions automatically, it’s worth measuring one segment (e.g., the length of a selected wall) with a traditional tape measure and comparing it to the value on the plan. If there’s a difference, you can calibrate the project by applying a correction. Such a reference point helps eliminate any minor scan discrepancies.
• Scan with Care: Slowly sweep corners and edges of rooms. Abrupt movements can cause the scanner to temporarily lose track. Make sure every corner (internal and external) has been “viewed” by the camera from two sides—this will ensure correct detection of the right angle between walls. If you have mirrors or glass surfaces on walls, try pointing the phone at different angles—shiny, reflective surfaces can interfere with LiDAR signal reception, so it’s worth collecting data from multiple shots.
• Perimeter and Area Control: After completing the scan, look at the total perimeter and area of the apartment provided by the application. Compare the total area with what you expect (e.g., from property documents). If the differences are greater than 1-2%, check if you missed any corners during scanning. AdPlan usually provides area with an accuracy of ±1 cm on a wall, which results in a very small error overall. If the result significantly deviates, consider a short supplementary scan of the difficult spot.
• Use Manual Mode: If perfect precision is paramount, use the manual corner correction mode available in the application. It allows you to click a detected point (e.g., a room corner) and optionally move it by a small offset to match a known dimension. The application automatically detects right angles, but this function is useful when, for example, a wall is not perfectly straight—you can add an additional break point to the line, replicating a subtle deviation in the wall’s path.
• Document and Describe: Finally, add notes on materials or construction to the plan if important (e.g., mark which walls are load-bearing, where internal partition walls are). AdPlan allows saving notes or photos to the project, which can be helpful. With a complete, personalized apartment plan, it’s easier to answer frequently asked client questions (e.g., about exact room sizes, wall thicknesses, utility layouts on the plan) already at the quoting or consultation stage.

With the above tips, you will get an accurate and reliable plan—ready for both technical and presentation purposes. Laser scanning of interiors is the future, happening now—it saves time, minimizes errors, and allows you to focus on the actual work instead of redrawing plans.
