Scan4+ turns real objects and rooms into 3D models on iPhone and iPad with LiDAR — then measure them, view them in AR and export them to the formats your workflow needs. OBJECT SCANNING • Guided Object Capture: walk around an object and Scan4+ reconstructs a textured 3D model on your device. • Precision mode for detailed objects. ROOM SCANNING & FLOOR PLANS • Scan rooms with Apple RoomPlan: walls, doors, windows and furniture. • Photo textures from your scan are applied to walls and floors. • Floor plan with wall lengths, floor area, ceiling height and furniture. • Export the room as a 3D model and as DXF or SVG floor plans for CAD. MEASURE & INSPECT • Tap two points to measure distances in mm, cm, m or inches. • Model bounds, vertex and triangle counts, wireframe view. • Open any model in AR Quick Look. • Browse your library beside a model on wide displays, or view a room's 3D model beside its floor plan. • Search room contents, furniture and dates; favorite models and choose your preferred sort order. EXPORT & SHARE • Free: USDZ and GLB. • Scan4+ Pro: OBJ with textures, STL in millimetres for 3D printing, PLY, XYZ, PCD and PTS, DXF and SVG floor plans, RoomPlan JSON. • Share a web link that opens your model in any browser. Web downloads support USDZ and GLB, plus OBJ and STL with Pro. Point-cloud and floor-plan exports are generated on your device. • Pro adds password-protected and expiring links. Keep your existing access options when updating a link. • Import USDZ models into your library. TRY IT ON ANY DEVICE • Built-in sample models let you explore inspection, measuring, floor plans and export even on devices without LiDAR. • Scanning requires an iPhone or iPad with a LiDAR Scanner.
