## What is STEP scan?

STEP scan is a surveying and drawing tool for architects, designers and builders: survey a room with the LiDAR of your iPhone Pro or iPad Pro, then draw over the scan on iPad.

SCAN + DRAW (iPad)
Finish a survey and tap “Draw over”. The scan becomes the background of a new drawing, on its own locked layer: a point cloud is sliced like a floor plan, a room survey puts its walls and openings in place. Then trace with Apple Pencil:
• lines, arcs, polylines, curves, rectangles, circles
• walls, doors and windows, hatches, a library of blocks, text
• simple, diagonal and angle dimensions
• move, rotate, mirror, scale, offset, trim, extend, join
• sheets with a title block and a scale, printed or exported to PDF
Drawings open and save as DXF.

EXPERT SCAN
Walk through a space and capture it as a dense point cloud, live. Each scan keeps its point count and duration, and exports as PLY + JSON.

ROOM SURVEY
Sweep the walls, then the doors and windows. STEP scan recognises the room, places its walls, corners and openings, and gives you:
• an editable 2D plan with dimensions
• the estimated area, perimeter and wall height
• a 3D view with doors and windows in place
• measurements taken directly on the plan
Plans export as DXF, together with the editable plan and the survey data in JSON.

MY SCANS
All your surveys in one library: thumbnails, folders, a map of where each survey was taken, a 3D point-cloud viewer and section views.

COMPOSITIONS
Assemble surveyed rooms into a floor.

PRIVATE BY DESIGN
No account required, no ads, no tracking. Your surveys stay on your device and only leave it when you share them. The location of a survey is only used for your map and is never added to exported files.
