In van conversion and motorhome customization, capturing complex interior geometry and producing high-precision fitted panels are critical but traditionally time-consuming and labor-intensive processes.

A professional conversion workshop in Portugal has introduced the 3DeVOK MT handheld 3D scanner to establish a digital workflow combining 3D scanning, CAD design, and CNC machining. By replacing manual measurement and physical templates with digital data capture, the workshop reduced measurement time from several hours to just over ten minutes, improved overall conversion efficiency by approximately 70%, and significantly enhanced panel fit accuracy.

Traditional Workflow Challenges in Van Conversion

The workshop specializes in interior customization for commercial vehicles, campervans, and specialty work vehicles. Clients typically require high-precision wooden interiors with tight tolerances and short delivery cycles.

However, the traditional workflow presents several limitations:

- Time‑consuming measurement: workers use tape measures and cardboard templates to manually measure and trace inside the van—taking 2–3 hours per vehicle, with curved surfaces and corners proving particularly difficult to capture accurately.

- Trial‑and‑error cutting: panels are cut, carried to the van for test fitting, marked where they don't fit, taken back for trimming, and tested again—sometimes three or four iterations per panel.

- Labour‑intensive installation: final fitting still requires on‑site edge trimming and shim adjustments, often taking a full day to complete the wooden interior of a single van.

As the workshop’s technical lead explained,

“Once order volume increased, the traditional workflow could no longer keep up. We needed a faster and more accurate digital approach that could connect directly to our machining equipment.”

Digital Upgrade: 3DeVOK MT Enables Scan-to-CAD Workflow

To address these challenges, the workshop implemented the 3DeVOK MT handheld 3D scanner and integrated it with its existing CNC machining system, establishing a complete scan-to-CAD-to-manufacturing workflow.

Step 1: 3D Scanning– Rapid Digitization of Van Interior Geometry

Technicians use the 3DeVOK MT handheld 3D scanner to capture the full interior structure of the van in approximately ten minutes.

The MT enables efficient data acquisition through infrared speckle-based scanning technology, offering two key advantages:

- Large scanning area: a single scan covers a wide field, up to 1,100mm × 1,000mm. A standard van interior can be fully scanned in just over ten minutes.

- No targets or spray powder required: Although the van interior is metal, its matte paint finish and abundant geometric features – such as reinforcing ribs and contoured surfaces – allow the MT's infrared speckle technology to capture data effectively.

During scanning, a 3D mesh model of the van's interior walls is generated in real time on the computer. Every reinforcing rib, every rivet hole, and every curved corner is captured in full detail.

As the operator noted, “It allows us to capture the full interior geometry quickly and reliably, turning the van into a precise digital model for downstream design.”

Step 2: CAD Design – Scan-to-CAD for Custom Interior Panels

The scanned mesh data is directly imported into CAD software, forming the basis for a scan-to-CAD workflow.

Designers develop customized wooden panels and cabinetry based on the actual interior geometry of each vehicle:

- The scanned model serves as an accurate digital reference for all design operations.

- Cut-outs, joints, and cable routing paths are designed directly within the 3D environment.

All adjustments are completed digitally before manufacturing begins.

This workflow eliminates the need for cardboard templates and repeated physical trial fitting, significantly reducing material waste and production time.

Step 3: CNC Machining – Automated Fabrication from Digital Models

Once the CAD design is finalized, machining data is exported directly to a CNC router.

The machine automatically processes all contours, holes, and structural features in a single operation. Because the design is based on real-world scan data, the finished components achieve a precise fit on the first installation, eliminating the need for on-site trimming or manual adjustment.

Results: Higher Efficiency and Improved Accuracy

By combining the 3DeVOK MT with CNC equipment, the workshop has successfully transitioned from manual templating to digital manufacturing. Measurement time is cut by around 90%, while overall conversion efficiency rises by approximately 70%. At the same time, material waste and rework are significantly reduced, delivering greater consistency and a professional finish for the van interiors.

Conclusion: Enabling Digital Manufacturing in Van Conversion

This case demonstrates how 3D scanning technology is transforming traditional van conversion workflows. By integrating the 3DeVOK MT handheld 3D scanner with CAD design and CNC machining, the workshop established a complete scan-to-CAD digital pipeline that improves efficiency, accuracy, and repeatability.

As digital manufacturing continues to evolve, 3D scanning is becoming a key enabling technology for customized vehicle interiors and precision fabrication workflows.
