Fix a stale cBOM

To fix a stale cBOM, you need to check out the stale assembly or drawing, ensure it updates with the latest version of its children, and check it back in so that these changes are saved into Upchain. The following outlines a more detailed approach to fix stale models and drawings.

Fix a stale drawing

Download the stale drawing and the latest version of its model.
Open the drawing in your CAD software.
Switch to and refresh the cBOM view.

The cBOM view should show the drawing at the top with the model as its child. The model should be the latest version ie. no grey highlighting or warning symbols.
Right-click the drawing and select Check out. Do not check out the model.
Right-click the drawing and select Check in.

The drawing file version increments by one and now references the latest version of its model. You can run the Stale cBOM report again to ensure you have fixed the stale drawing.

Fix a stale model

Download the latest version of the assembly and its child components.
Open the assembly in your CAD software.
Switch to and refresh the cBOM view.
Right-click assembly and select Check out. You must also check out all sub-assembly parents above the part/sub-assembly identified as being stale. You do not need to check out the part/sub-assembly identified as being stale.
Rebuild and save the assembly locally, if necessary.
Refresh the cBOM view again.
Right-click the assembly and select Check in.

Check that file versions for each parent listed in the report have incremented by one. You can run the Stale cBOM report again to ensure you have fixed the stale model.

Note: When checking in an assembly, Upchain may not create new file versions of its sub-assemblies if it does not see any model changes. If this happens, check out the assembly and each parent sub-assembly above the stale part/sub-assembly again. Then right-click on each sub-assembly and check them in one at a time, starting with the lowest-level parent of the stale part/sub-assembly first and working upwards.
