Inventory designs and representations
Create a design-level inventory alongside a file-level manifest. Count an assembly, its component drawings, exported sheets and revision history separately. Explain the counting convention so a buyer cannot mistake a folder total for independent designs. Preserve source filenames internally, but use approved asset identifiers in external descriptions.
DWG and DXF are not interchangeable promises of usability. The Library of Congress describes both in its design-format guidance. Record the authoring product and version, the export version and the receiving application used for validation. Format recognition does not demonstrate that all content survived an export.

Capture the dependencies that matter
List external references, fonts, images, linked specifications and other files required to interpret a drawing. Check whether a missing reference hides dimensions, title-block information or an entire assembly context. Do not silently package third-party references simply because the authoring tool can collect them.
For DXF, Autodesk documents sections such as HEADER, BLOCKS and ENTITIES. Use that reference to understand the exported structure, then validate what your actual archive contains. A file that opens without error can still use an unexpected unit convention or omit application-specific meaning.
| Check | Record | Escalate when |
|---|---|---|
| Units and scale | Drawing units and conversion rule | Different files imply conflicting dimensions |
| References | Dependencies and availability | Interpretation depends on a missing file |
| Layers and blocks | Names, purpose and export behavior | Important content disappears or flattens |
| Revision | Source version and superseded status | The current approved design is unclear |

Validate an evaluation derivative
Ask what the intended task requires. A dimension-reading exercise may use a rendered sheet; a geometry task may need entities or another approved design representation. Choose the smallest useful derivative instead of assuming that native files are always required.
Compare a sample of exported views with the approved source. Check page bounds, dimensions, annotations, layer visibility, block instances and orientation. Log the software version and settings used. Preserve known failures in a validation note rather than discarding difficult examples without explanation.
Review design rights before packaging
Prepare a contributor and agreement register. Distinguish company-authored designs from customer-controlled drawings, licensed components and supplier references. Where the archive exposes proprietary manufacturing methods or confidential specifications, obtain a scoped review before copying anything into an evaluation folder.
WIPO describes trade-secret protection in general terms; it does not decide the status of your engineering material. Have qualified reviewers assess the actual documents and proposed use. Keep unresolved material excluded and state whether exclusion changes assembly completeness or the usefulness of the proposed task.

A practical example
Illustrative scenario
Illustrative archive: one approved assembly exists as a native drawing, a DXF export and several PDF sheets. The manifest treats them as representations of one design lineage, records two unavailable references and excludes a customer-owned component until permission is resolved.
This is a constructed planning example, not a client story or completed transaction.
Questions and answers
Does a successful DXF export prove fidelity?
No. Check the exported representation against the approved source for the actual task.
Must drawings be translated into English?
Confirm the intended task first. Preserve the source language and a terminology map; translation can change technical meaning.
