When updating a version in an assembly, you must pay attention to what’s being updated, as you may inadvertently update instances to the latest version without meaning to.

How to Pin a Reference

Pinning a reference ensures specific references do not update until you are ready. To pin a reference, right-click on an instance that references a version and select Pin Reference from the menu.

The version icon next to that part or assembly now displays a thumbtack. This indicates a pinned reference.

As new versions are available, the icon changes but does not display in blue.

Opening the Reference Manager displays all instances with updates available except for the pinned references. When updating all references, the pinned instances are excluded.

Update to latest

Updating a Pinned Reference

To update a pinned reference, open the Reference Manager by selecting the version icon next to the pinned instance. Switch to Selective Update and update references as required.

Selective update

 To update multiple pinned references or the entire assembly at once, click on the update icon at the top of the graphics area, then switch to Selective Update. Check each box next to the instance you wish to update, then update as required.

You may also pin references on a drawing. First, reference a version of the part or assembly. Expand the Sheets pane, then right-click on the reference and select Pin Reference from the menu.

To unpin a reference, right-click on the thumbtack and select Unpin Reference. The instance now acts like any other version. If newer versions are available, the symbol updates accordingly.
