Engineering
Bridge the gap between the physical world and your digital workflow.
Engineering work is fundamentally about understanding what exists — and using that understanding to design, analyze, and improve. Whether the challenge is recreating a legacy component with no surviving drawings, verifying a prototype against its design intent, assessing existing infrastructure for retrofit design, or building a custom measurement system for a specialized test program, 3D scanning gives engineers accurate, complete data about the physical world — faster and more completely than any traditional measurement approach.
Persase in action — 3D scanning for engineering analysis, design verification, and infrastructure assessment
How Persase Serves Engineering
| Service | How engineering uses it |
|---|---|
| Reverse Engineering | Legacy components, physical prototypes, and undocumented hardware scanned and rebuilt as accurate CAD models — enabling modification, analysis, reproduction, and integration into modern design workflows without starting from scratch |
| Prototype & First Article Inspection | Complete as-built verification of prototypes against design intent — full surface comparison, GD&T evaluation, and deviation analysis that gives engineering teams the clear, actionable data they need to refine designs and release for production |
| Building & Site Laser Scanning | Accurate point cloud capture of existing infrastructure, facilities, and sites for structural assessment, retrofit design, and as-built documentation — providing the reliable base data that engineering analysis and design decisions depend on |
| As-Built BIM Models | Scan data converted into fully structured BIM models of existing buildings and infrastructure — ready to feed directly into structural analysis, MEP coordination, and retrofit design workflows |
| Custom Scan Systems | Purpose-built scanning and measurement systems for R&D, test, and validation programs — combining the right sensors, motion systems, and software for measurement requirements that standard instruments cannot address |
| Vision Systems | Custom camera-based inspection and dynamic tracking systems for engineering test programs — capturing data from moving parts, thermal processes, and real-time phenomena that require more than point-in-time measurement |

Why 3D Scanning for Engineering
Engineering problems rarely fit neatly into standard measurement categories. A component exists only as a physical part with no CAD file. A prototype comes back from fabrication and needs to be compared against design intent across every surface. An existing structure needs to be accurately documented before a retrofit can be designed. A test program requires a measurement system that doesn’t exist off the shelf. In each of these situations, traditional measurement tools — calipers, tape measures, contact probes — provide partial answers at best. 3D scanning provides complete answers — capturing full surface geometry, spatial relationships, and dimensional data across the entire object or environment in a single session.
For design and development, scan data closes the loop between physical reality and the digital model — whether that’s reverse engineering a legacy part into a CAD file, comparing a prototype against its nominal geometry, or capturing a physical test article for FEA mesh generation. For infrastructure and retrofit, accurate point clouds and as-built BIM models of existing structures give engineering teams the reliable base data they need to design around what actually exists — eliminating the field verification trips and dimensional surprises that slow retrofit projects down. For test and measurement, custom scanning and vision systems extend what’s measurable beyond what standard instruments can reach — capturing data from surfaces, processes, and phenomena that no off-the-shelf tool was designed to handle.
