PartDorinUpload RFQRFQReference hierarchy
Identify whether the drawing, approved sample, specification or application record controls each critical point.
Sample and drawing review
Custom automotive parts from controlled references.
A useful custom project begins by defining what the supplied sample, drawing or OE reference proves—and which material, dimension, interface, performance and packaging requirements still need agreement.

03Approval checkpoints
Buyer outcome
Translate the customer reference into a manufacturable scope.
A photograph may explain appearance, while a sample can reveal interfaces and a drawing may control dimensions. None automatically defines every requirement. The project review records which source governs each important characteristic and how changes or open points will be handled.
Technical questions
Surface missing material, tolerance, finish, connection, marking or test information before commercial approval.
Release criteria
Agree what evidence is needed for sample review, first-piece approval and shipment inspection.
Working sequence
From customer reference to controlled handoff.
The exact development route depends on product complexity, tooling and validation needs.
01
Receive
Review the drawing, sample, OE reference, application and target quantity.
02
Resolve
List controlled requirements, open technical questions and commercial assumptions.
03
Approve
Confirm the agreed sample, drawing revision or other release reference.
04
Control
Use the approved baseline for production coordination, inspection and packing.
What to send
Give the review a practical starting point.
PartDorin does not treat every sample as automatically reproducible or every OE reference as a complete specification. The review identifies whether the available evidence supports a quotation and what additional information is required.
Feasibility is assessed before capability is promised.
- 2D/3D drawing and revision status
- Physical sample or detailed product photographs
- Vehicle and product application
- Material, finish and critical dimensions
- Target quantity, packaging and validation expectations
