A project you can come back to
Saved calculations can be reopened, and connected rooms bring walls, openings, furniture and quantities into one editable plan.
Open your project list
Edit instead of starting over
Project-list items retain the inputs needed to reopen their calculator. Update an item, duplicate it or save a separate copy, with conflict checks when another tab has changed the project.
JSON backups preserve the supported project data. PDF quotation reports include material totals, sources and drawings, with pagination for larger lists. Files are generated in the browser.
Connected rooms
The new room editor supports drawing, moving and resizing rooms, placing furniture and editing doors and windows. Joined walls keep the room layout and material model connected.
Layers, Undo and Redo, rulers and measurements help refine the plan. The editor remains a preview while geometry and interaction are developed.
