Undrilled or factory drilled
Some fronts can be supplied undrilled for a competent fitter to drill. Others support standard positions or a specified custom drilling service. A supplier portal should not be assumed to accept every old hinge layout.
Define the references
Specify whether a drawing is viewed from the front or back and how positions are measured. Confirm cup geometry, edge reference, each centre position, handedness and restrictions near frames or rails. A left/right label alone is insufficient.
Unusual components
Angled fronts, corners, tall doors, integrated appliances and drawer fronts can have different fixing requirements. These need explicit product and fitting checks; a general dimension range does not certify compatibility.
Before production
A final schedule should identify the supplier code, finish, dimensions, quantity and drilling for every component. Corrections create a new version requiring fresh approval. Do not rely on an AI image to provide manufacturing measurements.
