PRECISION PHYSICAL GEOMETRY CAPTURE
Embedded Files
Useful Applications of 3D Scanning (Click Titles Below for More Information)
Interface and adapter design — Capturing mounting faces, hole patterns, clearances, and surrounding structure so that a newly designed bracket, guard, cooler, or attachment fits the existing machine without iterative trial fitting.
Local fabrication of supporting or replacement components — Enabling a domestic shop to produce a part that mates correctly with an imported or OEM assembly when the manufacturer will not release manufacturing files or data.
Support of productive legacy and NLA equipment — Allowing continued use and maintenance of machinery whose original support has ended, whose parts are no longer available, or whose files were never transferred, regardless of age or condition.
As-built documentation of installed systems — Recording the actual geometry and position of equipment after installation, modification, field adjustment, or wear for maintenance planning, future upgrades, or records.
Design of complementary tooling or fixtures — Creating inspection fixtures, assembly jigs, or handling equipment that must locate against complex existing geometry.
Verification of incoming or existing hardware — Comparing a physical part or sub-assembly against available (but incomplete) data, or establishing a measured baseline when no digital model exists.
Hybrid design where partial data exists — Using the scan to supply missing interface geometry while the remainder of the model is built from available drawings or new design intent.
Clearance and envelope studies — Defining the true spatial envelope of an installed component so that new equipment, guards, routing, or modifications can be designed to clear it without on-site rework.
Modification or upgrade of existing assemblies — Capturing current geometry so that performance improvements, sensor additions, strengthened elements, or other changes can be designed to fit the hardware already in place.
Rapid local response to supply-chain or data constraints — Providing the geometric foundation for a temporary or permanent domestic solution when overseas lead times, export restrictions, or refusal to release files interrupt normal supply.
3D scanning measures the real shape and position of existing equipment so new parts can be designed to fit it correctly the first time. When an overseas manufacturer will not release design files, when a part is no longer available, or when the hardware has been modified or worn, the physical item itself becomes the only reliable reference. Scanning captures the mounting surfaces, clearances, and surrounding structure so a new component can be created that installs without repeated adjustments or rework.
This approach is useful whenever something new must work with hardware that already exists. It supports the design of adapters and brackets, the local fabrication of replacement or supporting parts, documentation of how equipment is actually installed, and the creation of tooling or upgrades that match current conditions. The goal is functional compatibility with the equipment you already own, not a copy of the original design. The examples below show how this measurement process is applied in practice.
Registered 3D scan data, captured at a volumetric accuracy supporting local error on the order of 0.02 mm under controlled conditions, is brought directly into SolidWorks as a locked spatial reference. Model orientation is established against stable datums on the physical artifact; complex surfaces and positional relationships are taken from the scan while critical functional features are independently confirmed with contact instruments. The resulting parametric solid is then designed and toleranced to that measured envelope, so that the first fabricated article fits the existing hardware without iterative rework.
This seamless capture-to-SolidWorks workflow reduces the conventional cycle of trial fitting, revision, and re-machining. Interface geometry, clearances, and as-built conditions are known before the model is released, allowing a new component or assembly to move from concept through fabrication-ready design with minimal downstream changes. The outcome is a controlled, first-time-fit part that can proceed to production and sales on a shorter schedule.

As-built capture to SolidWorks
Existing equipment is captured with an optical-tracking laser scan. The result is a mesh of the as-built geometry. That mesh is not the product. The product is a SolidWorks model designed to that geometry so new parts fit what is already in the field.
What is captured
Structure that governs the new design: mounting faces, brackets, clearance volumes, and nearby members the new part must not hit. Entire machines are scanned only when the job requires it. Cosmetic coverage of every surface is not the default.
How the model is built
The mesh is aligned in SolidWorks and held as a constraint. New solids, weldments, and sheet metal are modeled top-down to that constraint. Features that will be manufactured are designed to stock and process, not traced as a decorative copy of the scan.
Accuracy
System volumetric accuracy (manufacturer specification): 0.025 mm + 0.04 mm × L, where L is the measured length in metres. Industrial CAD Works reports in-house scanned dimensions only to 0.045 mm (0.0018 in). Tighter values are referred to a CMM laboratory.
Deliverables
Cleaned mesh; SolidWorks model; drawings when required. Delivery is a license to use the files for the agreed project. Scan data remains the property of Industrial CAD Works, LLC, unless a written agreement assigns ownership.
What this is not
It is not a CMM inspection service. It is not a copy of a manufacturer’s original CAD. It is as-built geometry used to design the next part so it fits the first time.
Reducing 3D Scan Processing Costs with SolidWorks 2026 and Graphic References Drawing Sheet Integration
High-resolution 3D scan data has traditionally required extensive manual surfacing to convert into clean, editable solid-body models. While full Boundary Representation (BREP) conversion is sometimes necessary, it is often over-applied — and unnecessarily expensive — when the actual requirement is accurate reference geometry for design, weldment translation, or sheet metal development.
A More Efficient Path for Reference Engineering
SolidWorks 2026 allows high-resolution scan data to be inserted directly into drawing sheets as a Graphic Reference. This approach eliminates the need for full mesh-to-solidbody conversion in many common scenarios. When the goal is to reference critical locations, establish weldment translations, or design sheet metal components around existing geometry, the scan itself can serve as the driving reference without converting it into a solid model.
Key Advantages
Dramatically reduced processing time and project cost compared to traditional full BREP conversion.
Scan-true geometry available immediately in drawings for review and first-round fit-up validation.
Faster turnaround when the deliverable is primarily for reference rather than a fully parametric solid model.

Key Limitations (Current as of SOLIDWORKS 2025/2026)
Key Limitations (Current as of SOLIDWORKS 2025/2026)
Standard SOLIDWORKS BREP Bodies (Solid or Surface Body import without Mesh Body options):
Each facet converts to a standard BREP face.
Maximum: 500,000 facets (250,000 vertices) per mesh file for import as Solid/Surface Body. Exceeding this is not supported and typically fails or forces alternative import.
Performance degrades significantly with high facet counts due to the large number of resulting faces.
Mesh BREP Bodies (with "Create mesh bodies bounded by single faces" enabled):
Treats the mesh as a collection of facets forming BREP-like structures.
Warning threshold: >5,000,000 facets (2,500,000 vertices) (for both Mesh BREP and Graphics Bodies). This is a warning only; higher counts may succeed on high-end hardware (more RAM, faster processors) but can cause slowdowns or instability.
Graphics Bodies:
No strict hard limit on facets/vertices; imports faster as pure graphical data.
Suitable for very large scans (multi-million facets). You can later decimate or convert portions to Mesh BREP.
Historical / Older Limits (for Context)
Historical / Older Limits (for Context)
Earlier versions (e.g., around 2014) had tighter constraints: ~20,000 faces for solid bodies and ~100,000 for surface bodies (Parasolid knitting limits). These have been relaxed in modern releases.
In SolidWorks, facets are defined as the triangular polygons (or faces) that form the surface of a mesh body or imported scan data.
Key Details:
Key Details:
Mesh BREP Bodies: When you import or reference mesh/scan data (e.g., STL, OBJ, or 3D scan files), SolidWorks treats it as a Mesh BREP (Boundary Representation) body. These bodies are composed entirely of triangular facets. Each facet consists of:
Three vertices.
Three edges.
A triangular face.
Graphics Bodies vs. Mesh Bodies: Imported scan data often starts as a graphics body (faceted representation used for visualization). You can convert it to a full mesh body for editing, where the facets become editable elements.
Common Tools and Contexts:
Decimate Mesh Body: Reduces the number of facets while preserving shape. (Resolution Degrades)
Surface From Mesh: Selects groups of facets to create recognizable geometric features (planar, cylindrical, etc.).
Facet Groups: Tools like Paint Select Facets or Tangent Select Facets allow selection and grouping of these triangular elements.
