Four groups, and the group decides the format. Drawings (SVG, PDF, DXF, DWG) are the plan as a 2D sheet, with layers, paper size and a stated scale. 3D models (GLB, glTF, OBJ, Collada DAE, STL, 3MF, SKP, STEP, USDZ) are geometry you can move through, print or hand to a visualizer. Data (JSON, CSV, XLSX, IFC) is the model as structured information, room by room. Images (PNG, JPEG, WebP) are pictures of it, and nothing more. Pick the group by what the recipient will do next, then pick the format by what opens on their machine.
Which floor plan export do you need?
.usdz or .reality content.Any planWhat do the drawing exports give you?
Plan exports offer layers for rooms, walls, openings, fixtures, labels, and dimensions; A4, A3, or Letter paper; a scale from 1:10 to 1:1000; landscape or portrait orientation; and floor selection. The default is A3 landscape at 1:100 with every layer on. Every plan includes SVG and PDF at those defaults. Changing the paper, scale, orientation, layer set, or floor selection requires Pro or Team, which also includes DXF and DWG.
Choose SVG when the plan is going into a document, a website or a designer’s hands and will be restyled. Choose PDF when it is going to be printed or read, because the scale note and the paper size travel with it. Choose DXF or DWG when someone is going to draw on top of it: they arrive as CAD entities on layers, which is what a drafter needs and what a picture can never be.
What do the 3D model exports give you?
Geometry: rooms, walls and openings, with the fixtures and furniture placed in the editor. Each 3D export also names its source, which changes what is in the file more than the extension does. The canonical model is the reconstruction with your edits. The original-model source refers to a model associated with the project, not the floor plan PDF or image. A saved presentation build is one look you kept, so the file matches images you have already shown someone.
- Handing the model to someone else to render or animate: GLB first, glTF if they want to open the JSON, OBJ if their tool is old. See the Blender guide.
- Continuing to model the building yourself: SKP for SketchUp, or a drawing export as an underlay. See the DWG and DXF guide.
- Standing the space up at full size on a phone: USDZ. See the AR guide.
- Printing a physical model: 3MF where the slicer takes it, STL where it does not. See the 3D printing guide.
What do the data and image exports give you?
JSON carries the canonical model as structured data. Every plan includes all-row CSV and XLSX schedules. Filtering either schedule to rooms, walls, openings, fixtures, or finishes requires Pro or Team. A room schedule reports areas from the modeled room geometry, so measure the room itself when an area figure matters. IFC and STEP are Pro handoffs for building data or faceted surfaces rather than pictures.
Default PNG, JPEG, and WebP image exports are included on every plan at 1280 by 960. Custom camera views, a specified lighting preset, changed layer or object visibility, floor visibility, and nondefault sizes from 16 to 4096 px per side require Pro or Team. A plan view and a 3D view are different image choices, not different file formats. The daylight-neutral, warm-evening, and overcast-soft presets are presentation lighting, not a daylight study for your site and orientation.
Why does the file you downloaded not behave the way you expected?
- An import is not an export. A drawing goes in as PDF, PNG, JPEG, SVG, or DXF, up to 25 MiB. A building model goes in separately, up to 64 MiB: IFC and Apple RoomPlan files can open as walls, doors, windows and slabs you can edit when their shape can be verified; anything else, and GLB and other models, arrives as objects you can move and scale. What comes out is any of the twenty formats above, by plan. DXF appears on both lists and means different things on each: on the way in it is a drawing to reconstruct, on the way out it is a drawing generated from the model. DWG is an output only: export DXF from your CAD tool to upload it. See what you can import.
- An image download is not a mesh. A PNG of the 3D view cannot be opened in a 3D application, rotated, measured or printed. If the person asking for "the 3D file" plans to do any of those, they mean GLB, SKP or USDZ, and sending them a picture costs both of you a day.
Ask what the recipient must be able to change
Before choosing the extension, complete this sentence: “The recipient must be able to…” View a room, select a lamp, move a mesh, edit an architectural wall and revise electrical annotations are different finish conditions. Ask for the destination application and version, then test a small file there. A list of supported extensions cannot establish that the required objects remain editable.
For a home dashboard, a GLB may be an input only if the actual viewer accepts its organization and geometry. Device bindings, interactive behavior and tested Home Assistant compatibility are not supplied by the format name. For native CAD or Sweet Home 3D editing, ask what architectural entities the recipient requires; a mesh of the home is a different deliverable.
What INK TO BRICK does here
Exports need a plan. Every plan, from $6.99 a month, exports default SVG and PDF plans, GLB, glTF, OBJ, DAE, STL, 3MF and USDZ models, JSON, all-row CSV and XLSX schedules, and default PNG, JPEG and WebP images. Pro ($69 a month) and Team ($149 a month) add DXF, DWG, SKP, IFC and STEP, plus the drawing, image and schedule controls. Photoreal AI images are separate and use credits.
Two rules sit above the format list. The project creator or an assigned customer Editor with an available seat can use the export library, and only while the project is nonpublic; after you publish, the public viewer’s own GLB is what remains. And every export starts from the same place: an uploaded floor plan turned into a conceptual 3D model, which is what floor plan to 3D walks through. Current plan access is on the pricing page.
Try it and check your result
Write what the recipient needs to do: mark up a sheet, edit surfaces, read room data or look at an image. Pick one format from that group and confirm that their installed application imports it. Save and export the intended revision, then ask the recipient to open the file and identify one room and one known length. A successful download alone does not complete the handoff.
Inspect a reference in 3D
Orbit from two sides and locate an opening and a material boundary. Use those landmarks when checking a file in its destination application; this reference does not validate your import or export.
