Open the villa floor plan (PDF), set the X & Y scale,
then trace the inside perimeter to auto-build the cuplock layout.

Click 📐 Set scale, drag a ruler over any known dimension on the drawing (any direction) and type its real length in metres.

2 · Inside area

Perimeter m

Semi-auto: click ▭ Room box and drag a box over each room (one box per wall-bounded room; skip stairs/voids). The grid auto-fits each box, beams layer on top, then Generate. Backspace removes the last box.
Right-drag to pan · scroll to zoom (to cursor) · press Z for a magnifier.
Or use Trace perimeter (+ ⊾ Straight, ▢ Void) for a single auto outline instead of boxes.

Standards are inset from the walls by the edge offset; beams cantilever to the slab edge. Bay follows the slab-thickness rule (1.80 m ≤ 28 cm slab), capped at Max bay.

Set scale, trace the perimeter, enter slab data, then Generate.

Estimating aid only. Grid, beam and accessory quantities are an approximation for take-off — final design, load capacities, bracing and tie requirements must be checked and signed off by a qualified temporary-works/scaffold engineer.
