Flight path to finished plans
Move from blank canvas to export in under ten minutes. Follow the waypoints and watch the grid light up as you progress.
Stage 01 · Plot
Trace the shell
Drop the perimeter, clamp to the blueprint grid, and lock orientation so every wall is dead straight.
Stage 02 · Calibrate
Dial dimensions
Feed in key spans, toggle metric/imperial, and surface live area totals before furniture even hits the canvas.
Stage 03 · Equip
Load fixtures + furniture
Snap in doors, windows, and scaled furniture modules. Clearance warnings pop whenever spacing gets tight.
Stage 04 · Deploy
Export + broadcast
Ship crisp SVG/PNG or spin up a live link for teammates. Turn on reviewer mode to gather notes in minutes.
