1. Overview of Capabilities
Realsee Auto CAD automatically generates a standard structural CAD floor plan (.DXF&.DWG format) by processing high-precision 3D spatial data captured by Realsee LiDAR scanners (Galois and Poincaré series).
-
Core Deliverables: Wall layouts, room dimensions, net area/perimeter calculations, door and window openings (outer-frame dimensions), flat ceiling height zones, and sloped ceiling elevation points. Multi-floor projects are supported and delivered within a single file.
-
Intended Use: The output serves as an original structural base map containing core dimensions. It is optimized for standard, enclosed indoor environments (e.g., residential properties, apartments).
2. Structural Capability Scope & Boundary Conditions
The automation algorithm recognizes spatial structures based on standardized physical rules. Complex architectural elements or specific spatial configurations fall outside the scope of automatic generation and will require manual adjustment or supplementary drafting work. To learn how to use the web-based CAD editor for quick corrections and manual refinement, please refer to the CAD Editor Manual Adjustment Tool Tutorial.
-
Wall & Layout Boundaries:
-
Supported: Rooms enclosed by straight walls (e.g., standard rectangular or standard polygonal layouts).
-
Unsupported (Requires Manual Editing): Curved walls, irregular or organic structural layouts, open-air spaces without ceilings, double-height voids, and split-level/loft open areas.
-
-
Door & Window Recognition Boundaries:
-
Supported: Fully visible openings. Dimensions are calculated based on the outer bounding box of the opening visible on the wall. Interior doors are represented by the position of the walls on both sides (excluding door frames; frames are calculated as part of the wall).
-
Unsupported (Requires Manual Editing): Special openings with railings or mesh screens. Openings blocked by heavy curtains, cabinets, or furniture will only be processed and output based on the visible parts.
-
-
Ceiling Height Boundaries:
-
Flat Ceilings: Highly reliable. Height differences of approximately 3 cm or more will be automatically displayed as separate height zones.
-
Sloped Ceilings: The system does not fit a continuous sloped plane; it only outputs specific elevation values based on the points selected/measured in the editor.
-
Curved/Vaulted Ceilings: Outside the capability scope; dimension accuracy cannot be guaranteed.
-
3. Strict Project Capture Limits
To ensure successful processing and figure generation, the project must strictly comply with the following physical data limits:
-
Area Limit: The total area of a single project must be under 1,000 square meters. Projects exceeding this limit may fail to generate CAD due to point cloud calculation constraints. Large-scale spaces must be segmented into separate projects during capture.
-
Duration Limit (Poincaré Only): When using Poincaré series devices, the total scanning duration for a single project must be kept under 15 minutes. Exceeding this limit may cause generation failure due to excessive data volume.
4. On-Site Preparation and Environmental Constraints
The accuracy of the automated CAD outputs heavily depends on the physical state of the environment during capture. The following conditions must be met on-site, or the resulting dimension precision may be reduced:
-
Lighting & Visibility: All scanning areas must maintain sufficient lighting (recommended >100 lux). Extremely dark environments may fail to register data correctly.
-
Material Restrictions: Large reflective surfaces (e.g., mirrors) or highly transparent materials (e.g., clear acrylic) scatter laser signals and may cause data corruption, low precision, or generation failure.
-
Door & Window Protocol: All interior doors and bathroom doors must remain fully open to ensure continuous spatial tracking. The main entrance door must remain closed to define the property's external boundary. Windows must be closed, and all curtains must be drawn completely open to expose the window frames.
-
Cabinet & Wardrobe Obstructions:
-
For full-height built-in wardrobes (floor-to-ceiling and spanning the entire wall), cabinet doors must be opened so the algorithm can capture the innermost panel as the wall boundary.
-
For standard standalone cabinets (not reaching the ceiling or covering the whole wall), doors must remain closed.
