# Import models and inspect dependency changes

Review a prepared model or typed reference-table import before saving it into the family draft.

Roles: author, reviewer

Use the engineering import workflow to prepare a complete model or reference-table change for inspection. Uploading a file is preparation, not a reviewed release. Preserve the engineering source and compare the typed meaning before adopting it into a saved draft.

## Prepare the supported file

In Import an engineering model or reference table, select Import type. For a table replacement, choose Table to replace and the Engineering file. Check the supported structure and intended family before submitting the file. Do not assume that a spreadsheet's displayed formatting preserves exact codes and types.

Read Prepared import, its counts, complete typed table differences and case checks. Compare added, changed and removed values with the controlled source. A numeric-looking identity may need to remain text, and a blank cell may have a different meaning from zero.

## Adopt only the checked content

Review the complete prepared model or table before saving it into the family draft. The normal saved model and independent cases remain the basis for proof and submission. A file does not contribute independent expectations merely by containing the model's own calculated answers.

Add a case exercising each meaningful dependency change. Give the reviewer the original source, prepared differences and expected effect. If the import is stale or the family changed, prepare a current view and inspect it again rather than carrying forward an old comparison.

## Withdraw an unsafe dependency separately

Reviewers can use Withdraw a component or reference table, choose the Pinned dependency and record the withdrawal reason. This is an engineering decision with consequences for results that depend on it. It does not rewrite the component or table inside an accepted historical result.

Inspect affected results and handover follow-up after withdrawal. Use [Withdraw and follow up](/manuals/factoryspec/withdraw-and-follow-up). The intended outcome is a traceable draft change or explicit withholding decision, with the exact source basis retained. Neither an import nor a dependency review qualifies a manufacturing family by itself.
