How 2D Floor Plan Drawing Works
Click to place your first wall. The editor snaps to standard angles and aligns to existing walls automatically. Click again to set the wall length and direction. Once your perimeter is closed, drop in doors, windows, and openings from the built-in library. Every dimension is calculated live, so you see room areas and wall lengths update as you draw.
When the layout is ready, switch to 3D with one click to walk through the result, test materials, or share an interactive view with your client. Your 2D plan and 3D model are the same project, so any change in one view reflects instantly in the other.
Step by step
- Open the 2D Plan view and click to place walls.
- Add doors, windows, and openings from the library.
- Insert furniture from the 3D furniture catalog.
- Review live measurements and room areas.
- Switch to 3D with one click to see your 3D floor plan.
- Export or share as PNG, PDF, DXF, IFC, GLTF, or SVG.

Who Uses 2D Floor Plan Software
Homeowners sketch renovation plans, kitchen layouts, and furniture arrangements before spending a dollar on contractors or store deliveries. The automatic measurements remove the risk of miscalculated room dimensions.
Interior designers start every client project in 2D. The clean top-down view is ideal for space planning, traffic flow analysis, and verifying that furniture pieces actually fit. Designs then flow into 3D for client presentations.
Real estate agents create 2D floor plans for property listings in minutes. Listings with floor plans receive more inquiries than those without.
Architects use the editor for conceptual layouts and early-stage client communication. While not a replacement for full CAD software, it bridges the gap between a sketch and a professional plan, exportable to DXF for CAD detailing.
Educators and students teach and learn spatial design and architectural basics in any classroom, on any device. No installation barrier and no learning curve for the basics.
