CASE STUDY: TRANSLUCENT MATERIAL

Field of Application: Yacht Maintenance

DELAMINATED GLASS

Over the years, marine glass has a tendency to delaminate. This is due to erosion and exposure to thermal and mechanical constraints.

The Problem: None of the glass balustrade elements of the rear upper deck were available as replacement part.

OUR SOLUTION

Our engineer flew onsite with a handheld scanner.

We prepared 7 glass panels and digitalized the original part within 0.025 mm precision.

The digital model was post-treated first using a geometric analysis software, then a CAD Software. The maximum deviation from original model was 0.3 mm. The CAD model curvature is always more accurate compared to the physical part.

Once quality criterion fulfilled, the CAD models have been exported as IGS\SPT model for the glass panels to be produced.

The client was then able to assemble a balustrade like brand new.

Technical information:

0.025 mm precision scan
STP or IGS export format
Significantly optimized file size

STEP 1

Digitalisation

The physical model was scanned to the highest precision. The overall length exceeds 10 m, with a height of nearly 600 mm

STEP 2

Model Reconstruction

Geometric analysis software provided the reference elements (Point, line, surface, cylinders etc ...), necessary to rebuild precisely the CAD Model.

Each of the 7 panel was created individually, The final rendering assembly created was one of the many quality check, since the curvature of the whole assembly is also inspected.

STEP 3

Quality Check

CAD and Scan model were overlayed.

The CAD Assembly was imported in the scan file.

The 10 m long assembly has been recreated within 0.3 mm of maximum deviation, from the real models.

For a stunning result, 3D data must be of utmost quality and precision.

BRAND NEW GLASS

The seven tailor made tinted glass panels manufactured from Mapeex data proved to be perfectly sized. They fit precisely the frame first time right.
