Le plan d'étage d'une annonce commerciale et la surface en pieds carrés d'un bail ne sont pas identiques. Le plan d'étage aide les prospects à visualiser l'agencement de l'espace. La surface est calculée selon une norme de mesure ; dans le secteur des bureaux, la norme BOMA est généralement utilisée pour déterminer la surface locative.
Vous pouvez créer un plan d'étage en une après-midi grâce à un scan réalisé avec un téléphone. Pour obtenir le chiffre officiel de la surface, vous devrez faire appel à un professionnel de la mesure. Ce guide explique comment réaliser un plan d'étage pour une annonce de bail commercial avec Polycam, quand utiliser Pix4D pour des projets plus vastes, et comment éviter d'utiliser des mesures issues de scans là où elles ne sont pas appropriées.
Points clés
- Polycam lets you scan with a LiDAR iPhone or iPad and quickly create an editable 2D or 3D floor plan right on your device. You can export your plan as a PDF, PNG, SVG, or layered DXF file.
- Pix4D's indoor workflow produces a 3D point cloud, not a drawn plan. It suits very large floors and survey-grade projects with a CAD drafter on the team.
- Scan accuracy can change in spaces larger than 5,000 square feet or near glass and shiny floors. Always double-check important measurements while you’re still on site.
Ce qu'un plan d'étage pour une annonce de bail commercial doit montrer
Avant toute visite, le courtier et l'architecte du prospect examineront le plan d'étage. Ils vérifieront les limites et les entrées de la suite, les lignes de fenêtres, les colonnes, les pièces fixes comme les sanitaires et les locaux techniques, ainsi que la taille globale. Chaque version doit inclure une rose des vents et une mention indiquant que les dimensions sont approximatives.
L'annonce doit comporter une image ou un PDF du plan d'étage. L'architecte du locataire aura besoin d'un fichier CAO pour tester l'aménagement. Polycam permet d'exporter ces deux types de fichiers à partir du même scan.
Ce dont vous aurez besoin
- You’ll need a LiDAR-enabled iPhone or iPad to capture the floor plan.
- Polycam’s Business plan, which costs $400 per user per year, includes floor plans and advanced measurement tools. Annual plans also include a 7-day free trial.
- Make sure you have permission from the owner and, if the suite is occupied, from the tenant. Remember, the scan will capture anything visible, like screens, whiteboards, or paperwork.
Polycam ou Pix4D pour les plans d'étage commerciaux
| Polycam | Pix4D (PIX4Dcatch + PIX4Dmatic) | |
|---|---|---|
| Built for | Floor plans, measurements, and sharing from one app | Photogrammetry and LiDAR for surveying and construction |
| Output | Editable 2D and 3D floor plan, generated on the device | 3D point clouds and models, with CAD-ready deliverables from desktop software |
| Large spaces | Extend mode for connected rooms, with wider tolerance over 5,000 sq ft | Multiple scans merged with printed Autotag targets |
| Extra steps to a plan | Review, label, export | Process, merge, then draft the plan in CAD |
| Best fit | Courtiers, propriétaires, gestionnaires immobiliers, entrepreneurs en aménagement | Équipes de relevé et VDC, bâtiments complets, projets géoréférencés |
When scanning large interiors, positional errors can build up. This is a phenomenon called drift. To help adjust for this drift, Pix4D recommends that you place printed Autotags around the space. In their test, a phone with tag detection had an average error of 7 pixels, compared to 41 pixels without tags. Using this method, Pix4D mapped a 2,000-square-meter office with five merged scans and about 5,000 photos.
The result is a merged point cloud in PIX4Dmatic, Pix4D’s desktop software. To turn this into a floor plan for a listing, someone still needs to trace the walls in CAD. This approach works well for mapping an entire building, projects that need site coordinates, or teams already using CAD. If you just need a plan for a suite or single floor quickly, Polycam is faster.
How to Make the Floor Plan With Polycam
1. Prepare the space
Turn on all the lights, because low lighting can make the scan less accurate. Glass partitions and polished concrete, which are common in offices, can scatter the sensor’s signal. After scanning, check these areas carefully.
2. Plan your route and begin to scan
Choisissezle mode Espace si vous souhaitez obtenir à la fois un maillage 3D et un plan d'étage, ou utilisez le mode Plan d'étage pour un tour rapide du périmètre. Restez à une distance de 1 à 2 mètres des surfaces, déplacez-vous lentement et capturez chaque jonction entre les murs et le sol ainsi que chaque angle.
Plan the order in which you’ll scan the rooms before you start. For example, when I scanned a two-story house without planning, I walked through the main hallway several times, which left unwanted artifacts in the 3D mesh. Office corridors can cause the same problem, since scanning the same spot more than once creates conflicting data.
If you’re scanning a large floor, break it into zones. Measurements are usually more accurate within a single segment than across several, so treat each zone as a separate reference area.
3. Edit and label
The plan will process on your device in just a few minutes. You can rename rooms, adjust walls, edit door and window openings, and remove any furniture you don’t want to show. Switch between metric and imperial units as needed.
4. Verify your capture before you publish
Polycam’s standard interior scans are accurate within about half an inch. This tolerance can get wider if the space is complex or large. Since errors can add up over longer distances, always check the longest measurements with a laser first.
5. Export for each audience
Export a PDF or PNG for the listing and offering memorandum, and use a layered DXF file for importing into AutoCAD or Revit. You can also share a link to the 3D model, so out-of-town prospects can view the space before visiting.
Already Have an Old Plan? Digitize It
De nombreux propriétaires disposent d'un plan au format PDF ou papier datant du dernier aménagement. Lenumériseur de plans d'étage de Polycam peut traiter des fichiers JPG, PNG ou PDF, voire des photos de plans imprimés, pour les transformer en plans modifiables incluant murs, portes, fenêtres et estimations des dimensions des pièces. Cette méthode est efficace si l'agencement n'a pas été modifié depuis la création du dessin. En cas de travaux d'aménagement, scannez à nouveau l'espace.
Square Footage: What the Scan Can and Can't Tell You
LeRapport spatial fournit la surface au sol, les dimensions des pièces et la hauteur sous plafond de l'espace numérisé. Ces données facilitent la planification et permettent de répondre aux questions des prospects.
La surface locative ne fait pas partie de ces chiffres. La norme BOMA 2024 pour les bureaux, ANSI/BOMA Z65.1-2024, permet de la calculer et couvre les configurations à locataire unique, à locataires multiples et multi-immeubles. Le scan d'une suite mesure ce qui se trouve à l'intérieur des murs que vous avez parcourus, et non un chiffre calculé selon cette norme. Publiez le plan sur l'annonce et faites appel à un professionnel de la mesure pour déterminer la surface locative.

2. Plan your route and begin to scan
Choose Space mode if you want both a 3D mesh and a floor plan, or use Floorplan mode for a quicker walk around the perimeter. Stay 3 to 6 feet from surfaces, move slowly, and capture every wall-floor junction and corner.

Already Have an Old Plan? Digitize It
Many landlords have a PDF or paper plan from the last build-out. Polycam’s floor plan digitizer can take JPG, PNG, or PDF files, even photos of printed plans, and turn them into editable plans with walls, doors, windows, and estimated room sizes. This works if the layout hasn’t changed since the drawing was made. If there’s been a build-out, scan the space again.

The Spatial Report provides the floor area, room sizes, and ceiling heights for the space you scanned. These numbers help with planning and answering questions from prospects.
