Bring in a PDF. Check the detected walls and openings, confirm the scale, and align up to two floors.
YOUR SKETCH OR PDF. YOUR NEXT IDEA.
From napkin
sketch to
furnished 3D.
Sketch a room, label the furniture and dimensions, and take a photo. Review the result, then explore your furnished 3D space. Already have a PDF floor plan? Start there, too.
Free with an account: use clear labels and confirm dimensions. AI recognition is available with Plus. Furniture uses editable catalog approximations.

One connected workflow
IMPORT→EDIT→FURNISH→PRESENT→EXPORT
01 / FROM PLAN TO POSSIBILITY
A clearer picture, at every step.
Keep the dimensions, the design and the decisions in your hands.
Shape your space
Edit in 2D or 3D. Change dimensions, add doors and windows, and fit a roof to your structure.
Make room for living
Use Furnish for suggested room layouts, then move and adjust individual furniture pieces.
Present & take it further
Explore your design, play the construction sequence, render an image or export the model.
Best with clear vector PDFs. Scanned plans need scale calibration and manual tracing; always review the detected layout.
02 / YOUR DESIGN, YOUR DECISIONS
Go beyond
the floor plan.
LIVING ROOM · KITCHEN · BEDROOMS
Rooms with a purpose. Furniture that fits.
Room names from your PDF help suggest the right furniture. Review the room types, choose which spaces to furnish, and refine the arrangement in the Interior Design studio.
- Living rooms, bedrooms, kitchens, bathrooms and offices
- Editable furniture from the built-in catalog
- Individual floors or the entire house
Change the details. See the difference.
Resize walls and floors, adjust roof height and style, and choose finishes for your design.
Give your model its best light.
Use the optional realistic renderer for softer shadows, reflections and material detail. Choose lighting and exposure.
Show how it comes together.
Play a progressive construction sequence. Furniture joins the animation when your project has been furnished.
03 / KEEP YOUR PROJECT MOVING
Create here. Continue anywhere.
Take the latest version of your building into your next workflow. Save an editable project, export geometry, or prepare an image for a presentation.

06 / GOOD TO KNOW
A few things, before you begin.
Does every PDF convert automatically?
Clear vector plans with straight walls work best. You review the detected walls, doors, windows and scale before generating the model. Scans require manual calibration and tracing; stairs, complex outlines and other details may need manual work.
Can I change the model after importing?
Yes. Edit the building in 2D or 3D, adjust dimensions and openings, add roofs, and arrange furniture. Your edits live in the Building3D project; the original PDF stays unchanged.
How does automatic furnishing work?
Building3D uses room labels and the current walls to suggest furniture from its catalog. You can correct room types, choose rooms to update and edit individual items. Suggestions depend on available space and need your review.
Can I use Building3D on my phone?
Yes. The editor includes controls for phones, tablets and computers. Larger models and high-quality renders benefit from a more capable device. Rendering time depends on your hardware and the selected quality.
Do I need an account to try it?
You can explore the editor without signing in. Create a free account to save projects online. Save your work or download a project JSON before refreshing or closing the editor.
Are the results ready for construction?
Building3D helps with design concepts, visualization and model exchange. Have dimensions, structure, building-code compliance and exported files reviewed by a qualified professional before using them for construction.
