# Linked models

> Identify ownership and references when working with linked geometry.

Reading a linked element, referencing it from the host and editing its source document are different operations. Check support for the exact task before relying on a link.

<h2 id="identify-ownership">
  1\. Identify ownership
</h2>

Name the host document, link instance and source element where available. Separate host elements from linked geometry in the requested scope. A host-grid result does not demonstrate that a linked-wall reference works.

<h2 id="check-the-prerequisite">
  2\. Check the prerequisite
</h2>

For dimensions, inspect the native reference. For a family, check its hosting requirements and the actual placement environment. Do not create substitute geometry solely to bypass a link problem without reviewing the effect on the project.

<h2 id="test-one-case">
  3\. Test one case
</h2>

Start with one view and a known linked element. Inspect the result in the host and confirm which document changed. If selection or reference retrieval fails, capture the exact target and error for [Report a problem](/studio-reference/ui-support#problem-reports); avoid generalizing a workaround to every linked model.
