A reclaimed Ulin component drawing should identify the face and edge from which critical dimensions are measured. Without those references, two correctly measured pieces can still place a hole, rebate or connection differently. This is especially important when one visible surface retains reclaimed character while another is machined to meet a precise assembly requirement.
Reference faces connect the design to machining and inspection. They do not turn naturally varied timber into an automatically graded structural product. The architect, contractor and responsible technical professional still need to define the component's role, connection requirements and acceptance criteria for the actual project.
Begin with the assembled relationship
Ask what the component must align with when installed. A post may meet a metal shoe, a beam may connect to another member, or a repeated batten may need to sit on a common line. Identify those interfaces before deciding which timber surface will serve as the dimensional reference.
The most visually prominent face is not always the most useful machining reference. A deliberately rustic surface can vary while a concealed bearing or connection face needs controlled geometry. The drawing should explain how both requirements will be achieved without leaving the workshop to choose between them.
Naturanexa's beams and structural timber and battens, joists and rafters cover different component roles. An enquiry should identify the application and the important interfaces rather than relying on a nominal section alone.
Name the reference face and edge
Use a clear drawing convention to identify the primary face and the edge used for setting out. Explain the convention in a legend and keep it consistent across the component schedule. The workshop and the site team should be able to interpret it without relying on a private verbal explanation.
For example, a designer may define the concealed machined face as the starting plane for a connection detail while preserving the opposite face's reclaimed character. This is a hypothetical specification approach, not a default Naturanexa product promise. Its feasibility must be reviewed against the available material and required finished section.
Avoid describing a location only as the front or left side unless the viewing direction is explicit. A component can be turned over on a bench or viewed from the opposite end on site. Add an orientation view or end reference where it prevents a plausible but incorrect interpretation.
Dimension the feature from the intended reference
Place critical dimensions so that the workshop can see what controls the feature. A hole centre measured from a machined face may serve a different purpose from one centred within an irregular overall width. State which relationship is required rather than assuming both descriptions produce the same result.
Be cautious with long chains of dependent dimensions. Where several features must align with an external assembly, the responsible designer should choose a dimensioning method that reflects that relationship. This article does not prescribe a universal drafting standard or tolerance; the project team must define the appropriate method.
Show dimensions in one agreed unit and distinguish finished dimensions from the starting stock. A reclaimable piece must contain enough material to achieve the required faces and features after machining. A nominal raw section should not be presented as proof that every finished detail can be recovered from it.
Separate visible character from connection geometry
Describe where reclaimed texture, old holes or surface variation are acceptable and where the assembly requires a different condition. The same component can have different requirements in different zones. A general instruction to retain character is too broad when it also covers a bearing surface or a fixing location.
Use drawings and annotated photographs together. Photographs can communicate appearance, while drawings define geometry. Neither should silently override the other. If a selected piece has a feature near a proposed connection, bring that conflict back to the responsible designer before machining proceeds.
Do not classify a crack or historic hole as structurally acceptable merely because it contributes to the reclaimed appearance. Structural suitability requires the appropriate assessment. Naturanexa's material selection and machining discussion should remain separate from an engineer's approval of a load-bearing design.
Define orientation for repeated components
Repeated members can still have a preferred visible face or end orientation. A batten series may be intended to show a consistent relationship between the machined reference and the visible character. State whether components are interchangeable or allocated to specific positions.
Where handed parts are required, identify them separately. Mirrored components can be confusing when a drawing uses the same name for both and relies on someone to notice a reversed feature. A clear component reference helps production, inspection and site assembly refer to the same requirement.
Agree how temporary identification will be applied without compromising the intended finish. Do not assume ink, adhesive or a permanent mark is acceptable on a visible surface. The marking method and its location should be discussed with the workshop, especially for pieces that will remain unfinished.
Coordinate timber with adjoining materials
A timber component may need to meet fabricated steel, masonry or another prefabricated assembly. Share the relevant interface information and the status of the adjoining work. If the steelwork is still a preliminary design, that uncertainty belongs in the enquiry rather than being hidden behind a final-looking timber drawing.
Identify which party controls each interface dimension and how discrepancies will be resolved. A workshop should not have to choose between incompatible drawings from two suppliers. The contractor or designer should issue a coordinated basis before the affected machining is released.
Wood also responds to moisture conditions. The USDA Wood Handbook provides background on moisture behaviour, fastenings and engineering use. Precise machining does not eliminate movement or establish the adequacy of a connection; the responsible professional must account for those matters in the design.
Inspect using the same references
An inspection method should follow the references used to define the component. If production measures a feature from one face and inspection measures it from another, the teams may disagree even when their instruments are functioning correctly. Resolve the basis before setting acceptance criteria.
Record what is checked and how the piece is oriented during the check. Where a rough face is intentionally variable, avoid using its highest point as an accidental substitute for the defined reference. The measurement method should be suitable for the feature and the agreed drawing.
Keep appearance review separate from dimensional inspection. A component can satisfy the defined geometry while needing discussion about its visible character, or it can look appropriate while failing an interface requirement. A clear record distinguishes the questions rather than combining them into one unexplained approval.
Use a representative first component when appropriate
For repeated or unfamiliar details, discuss whether a first component or sample assembly would help confirm the interpretation before the full run. Its purpose is to check the agreed references, orientation and interfaces. It should not become an unrecorded opportunity to change the specification halfway through production.
If the review changes a feature, update the drawing and identify the affected quantities. Keep the approved version clear to both workshop and site. A photograph marked approved is insufficient if the dimensioned drawing still describes an earlier arrangement.
The same discipline applies when available reclaimed material requires a proposed adjustment. Record the alternative and obtain the responsible project's decision before treating it as the new requirement. Material character can inform design, but it should not create silent substitutions at critical interfaces.
Send a coordinated enquiry
A useful package includes the component schedule, finished dimensions, reference faces and edges, orientation, connection details, visible-surface requirements and the drawing revision. Add quantities and the intended application. Identify which details are final and which still need review.
This allows Naturanexa to discuss selection and machining against a clear purpose. The essential question is not whether reclaimed wood can be made precise in the abstract. It is which surfaces and relationships must be controlled for this assembly, and how that requirement can coexist with the character the designer wants to retain.
