Instructions:

• Set Room Width and Room Depth at the top — the canvas auto-fits the room to fill the work area
• Pick a Units value (ft, in, cm, m) — switching is a pure display change, your room and shapes keep their real size
• Enable the grid and snap-to-grid for accurate placement
• Add shapes with real-world dimensions (furniture, walls, etc.)
• Select a shape to edit its properties and click "Update Shape" to apply changes
• Drag the edges or corners of a selected shape to resize it
• Rotate shapes by entering a degree value or using the ↺/↻ buttons
• You can also drag the red rotation handle above any selected object
• Use the measurement tool to check distances between objects
• Add text labels to identify different items in your room plan
• Use the layer controls (↑/↓) to arrange objects in proper order
• Use keyboard shortcuts: Arrow keys to move objects, Ctrl+Z to undo, Ctrl+Y to redo, Ctrl+D to duplicate
• Use the Save Project button to download your design as a file
