When the parts catalogue ends.

Function comes first.

A cover, a bracket and an air duct can look equally unremarkable. Their jobs are different. Before creating any geometry, the installation position, interfaces, environment and loads need to be described.

Interaction with other components matters too. Does anything need to move? Must a connection be removable? How much space is available during installation? The original part is a reference, but it does not automatically provide a complete answer.

What makes a useful reference.

An aged or broken part does not always show its original shape. Reconstruction requires traceable dimensions, interface geometry and, wherever possible, a check within the actual installation space. A single photograph cannot replace that information.

• Identify the vehicle platform and installation position clearly.
• Record fastenings, mating parts and available clearance.
• Distinguish damage and possible distortion from the intended geometry.
• Document the requirements for the new component before manufacturing.

Reproduce or rethink?

A new version can offer an opportunity to rethink installation or geometry. Every change also raises new questions. The right answer depends on material, manufacturing process and application. A good rendering is not yet evidence that a part works in a vehicle.

SEKTOR16 is exploring this approach for selected plastic components. There is currently no available parts catalogue here and no commitment to support a particular vehicle. Future developments should make their reference, limitations and validation status clear.
