Reverse engineering often starts with a physical part but no reliable digital data. In restoration and customization, manual measurement can provide basic dimensions, but it becomes limiting when complex curves, mounting points, and tight clearances need to be captured accurately. MetroY Ultra captures the actual three-dimensional geometry of a part, providing a reliable digital reference for reverse engineering, custom design, and manufacturing.

In a custom 1984 Honda CB400 build, the builder needed to create a seat tray and seat pan for a custom seat while integrating the rear fender into the modified rear subframe. The challenge was not simply designing a new part, but making that part accurately fit a motorcycle whose geometry had already been modified. Traditionally, this kind of work is often done with welded sheet metal or fiberglass layup. Both methods can produce strong parts, but they also require cutting, trimming, sanding, fitting, and repeated manual adjustment.

Instead of starting with metalwork or fiberglass, the builder moved the project into a digital workflow. The motorcycle had already been 3D scanned, and MetroY Ultra was then used to capture the rear fender from multiple angles, including both the top surface and underside. Markers were placed on and around the fender to support stable tracking, and enough overlap was captured so the scan data could be merged into a complete model. The scan was captured and initially processed in Revo Metro, Revopoint's software for MetroY Ultra.
