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).

🔎 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.

✂ Crop image
Drag on the picture to choose the part to keep (the building only, without titles, borders or other plans). Drag the corners or edges to adjust, or the middle to move it. Shapes already drawn move with the crop so they stay lined up.
📐 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.

Pre-visit checklist
🗺 Building outline from OpenStreetMap
Finds the building's footprint and draws it on this floor in real metres, so you can divide the inside with the room list or zone tools. Needs an internet connection. Not every building is mapped, and new ones may be missing.
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.
