Scan-to-CAD: 2D As-Built Drawing Services from LiDAR Laser Scanning

Accurate 2D as-built drawings are the foundation of nearly every renovation, tenant improvement, and facility management project in commercial real estate. The question for most project teams isn’t whether they need them — it’s how to get drawings that actually match what’s in the field, delivered fast enough to keep the project moving.

Robotic Imaging’s Scan-to-CAD service answers that question with a clear process: LiDAR laser scanning captures the physical reality of a building at ±2–4mm accuracy, and that point cloud data becomes the source geometry for a complete set of 2D CAD drawings — floor plans, reflected ceiling plans, elevations, sections, MEP documentation, and more — delivered in 10–14 business days, starting from $0.19 per square foot.

This article covers what Scan-to-CAD is, what Robotic Imaging delivers, how the LOD levels work for 2D output, and when Scan-to-CAD is the right choice versus full Scan-to-BIM.

What Scan-to-CAD Is — And Why the Source Data Matters

Scan-to-CAD is the process of converting 3D laser scan data into accurate, dimensioned 2D CAD drawings. A field team uses LiDAR scanners to capture millions of spatial measurements throughout a building — walls, floors, ceilings, columns, MEP systems, openings, and fixtures — producing a registered point cloud that becomes the authoritative record of existing conditions. From that point cloud, CAD drafters build the 2D drawing set: floor plans, sections, elevations, reflected ceiling plans, and MEP documentation, all delivered in .DWG, .DXF, and .PDF formats.

The critical difference between Scan-to-CAD and a manually surveyed drawing set is the source data. A manual survey captures dimensions a person measures and records — walls that are reached, heights that are estimated, MEP routing that requires access panels. A point cloud captures every visible surface simultaneously, at ±2–4mm accuracy, including ceiling conditions, above-grid MEP routing, column profiles, and irregular geometry that manual measurement routinely misses or approximates.

The animation below shows this transformation directly — a real Robotic Imaging project, showing LiDAR scan data converted into a 2D building section drawing:

That source data quality flows directly into the drawing quality. A Scan-to-CAD floor plan derived from a LEICA RTC 360 point cloud is not the same as a floor plan traced from field notes — and on renovation projects, that difference is where change orders originate.

Level of Development for Scan-to-CAD: What Each LOD Means in 2D

Level of Development (LOD) defines how much detail is documented and modeled. In Scan-to-CAD, LOD governs how precisely elements are represented in the drawing, how completely MEP systems are traced, and what accuracy tolerance is maintained throughout. The right LOD depends on what the drawing will be used for downstream — not on a general preference for more or less detail.

LOD Level	What’s Documented	Accuracy Tolerance	Typical Use Case
LOD 200	Overall geometry, walls, major openings, approximate dimensions	±1/4 inch from point cloud	Space planning, portfolio documentation, early cost estimation
LOD 300	Exact dimensions and locations of all elements, accurate openings, precise column positions	±1/4 inch from point cloud	Construction documentation, permit drawings, design development
LOD 350	Full MEP system routing, connection points, equipment specs, system interfaces	±1/16–1/8 inch	MEP coordination, complex renovation, facility management handover
LOD 400	Fabrication-ready detail, weld locations, bolt patterns, material specifications	±1/16 inch	Historic preservation, complex structural steel, specialty fabrication

The LOD examples in Robotic Imaging’s service library — MEP Documentation, Space Planning, LOD 400 retail, LOD 350 facade, LOD 300 convenience store, LOD 300 building and site, LOD 300 floor plan, LOD 300 store, LOD 200 floor plan, LOD 200 elevation — reflect the actual range of projects where Scan-to-CAD is the right deliverable choice. Each represents a distinct project type with a distinct documentation need.

Scan-to-CAD by Project Type

The right LOD and deliverable set depends on the project. Here is how Scan-to-CAD maps to the most common commercial documentation scenarios:

Project Type	Recommended LOD	Key Deliverables	Why Scan-to-CAD Wins Here
Retail store renovation	LOD 300	Floor plan, RCP, storefront elevation	Fast multi-site turnaround, consistent accuracy across 50–500 locations
Commercial office TI	LOD 300–350	Floor plan, RCP, MEP rough-in	Eliminates field verification trips, catches hidden conditions before design
Historic preservation	LOD 350–400	All elevations, sections, facade drawings	Captures ornamental detail manual survey misses
MEP system documentation	LOD 350	MEP plan, sections, equipment schedules	Point cloud captures above-ceiling routing without destructive investigation
Space planning / portfolio	LOD 200	Floor plans, area calculations	Rapid multi-building documentation at lowest cost per sqft
Industrial facility	LOD 350	Equipment layouts, piping, structural	Dense environments where manual measurement is dangerous or slow
C-store / convenience retail	LOD 300	Floor plan, equipment layout, elevation	7-Eleven, Speedway programs at scale — verified Robotic Imaging deployments

Multi-location retail programs — convenience store rollouts, QSR renovations, retail rebrands across 50 to 500+ locations — are where Scan-to-CAD at LOD 300 delivers the highest ROI. Consistent accuracy, standardised drawing formats, and 10–14 business day delivery across simultaneous multi-site programs is what enables Robotic Imaging’s Fortune 500 retail clients — Walmart, 7-Eleven, Kroger, CVS, Nordstrom, and others — to run documentation programs at a scale that manual surveying cannot match.

Scan-to-CAD vs Scan-to-BIM: Which Do You Need?

The decision between Scan-to-CAD and Scan-to-BIM comes down to what the deliverable will be used for downstream.

Choose Scan-to-CAD when: The project requires 2D construction drawings for permitting, bidding, or renovation design. The design team works primarily in AutoCAD. No 3D coordination or clash detection is required. Budget favours the lower per-sqft cost of 2D output.

Choose Scan-to-BIM when: The project requires a Revit model because the design workflow is BIM-based or because MEP coordination across multiple trades requires 3D clash detection. The deliverable will be used for facility management after construction. The project is complex enough that a 3D model adds more value than a drawing set alone.

Both services start from the same LiDAR point cloud captured in the same 2–3 day field visit. Choosing Scan-to-CAD does not preclude upgrading to BIM later — the point cloud archive is delivered with all Scan-to-CAD projects and remains available for BIM model production at any future project phase.

Pricing and Timeline

Robotic Imaging’s Scan-to-CAD service starts at $0.19 per square foot — among the most accessible pricing for laser-scan-derived 2D documentation in the US market.

The complete delivery timeline from scheduling to final drawings:

• 2–3 days — Field technician dispatch and on-site laser scanning
• 3–5 days — Point cloud processing and registration
• 7–10 days — CAD drafting and quality verification
• 10–14 business days total — From scheduling to final deliverable

That timeline is 50–80% faster than traditional surveying for equivalent commercial scopes. For occupied buildings where floor access must be scheduled around tenants and operations, compressing site time to 2–3 days versus 1–2 weeks of traditional survey visits is a meaningful schedule advantage.

For multi-location programs, volume pricing applies. Projects covering 50 or more locations receive customised per-location pricing. Contact Robotic Imaging’s team with your location count and square footage for a program-level quote.
