Tips: Select: click a shape; Shift/Ctrl-click (or ☑ Multi-select on a tablet) adds more; drag empty space for a selection box (drag right-to-left to also catch shapes it only touches). Drag selected shapes – or anywhere inside the dashed frame – to move them together. Drag the square handles to resize (corners keep proportions, hold Shift to stretch); exact sizes can be typed in the Selected box. Ctrl+C / V / X copy, paste, cut · Ctrl+D duplicate · Ctrl+A select all · Delete removes · arrow keys nudge (Shift = bigger) · Ctrl+Z / Ctrl+Y undo / redo. Double-click an edge to add a corner, a corner to remove it. Drawing: click points, double-click or Enter to finish, Backspace removes the last point, Esc cancels, hold Shift (or ⊾ Straight) for straight lines; 🧲 Snap joins to nearby corners. Scroll = zoom; Space + drag, or middle mouse, pans.

🔎 Web search for a floor plan

Results vary: many buildings have no public plan. Asking the client with ✉ Request plans is usually more reliable.

Enter the building address. Each link opens a targeted search in a new tab. When you find a plan: right-click → Copy image, come back here and press Ctrl+V (⌘V on Mac). Or save it and drag it onto the drawing, or use Photo / PDF / image. PDF plans load directly.

📐 Straighten photo

Tap or drag the four red corners onto the corners of the plan (or the sheet of paper), then Apply. Use Rotate first if it is sideways. This squares up photos taken at an angle so rooms can be detected.

🏠 Room list

No drawing needed: list each room on this floor with its size in metres (Width = across the plan, Depth = up and down the plan) and where it sits. The app lays them out around a corridor to scale. Then drag walls or corners to fix anything, and use 🎯 Assign rooms to zones to make zones.

🪄 Auto-convert image to editable shapes

Reads the plan image on this floor and creates the shapes a person would have drawn, so you can edit, rename and move them. Works best on a clean, dark-lined plan, or a photo of one that has been straightened. Ordinary photos of rooms can't be converted. Ordinary photos of rooms can't be converted. The toolbar's Gap closing and Wall sensitivity sliders apply.

Lower it to catch short walls (cupboards, cubicles); raise it if text or furniture is being traced. Text and furniture are removed before tracing; use Preview to see what will be traced.
