solidworks Model dimension did not update, even with automatique update turn on, is it a bug?

Check if the Drawing Views are Locked:

Ensure that the drawing views are not locked. If they are locked, updates to the model will not reflect in the drawing.
Rebuild the Model and Drawing:

Use the Rebuild function (Ctrl+B) in both the model and the drawing. Sometimes, a manual rebuild is needed to update dimensions.
Try using Force Rebuild (Ctrl+Q), which is more thorough than a regular rebuild.
Update Drawing Views:

Right-click on the drawing view and select Properties, then check if the option to Automatically update views when model changes is enabled.
Manually update the drawing view by right-clicking on it and selecting Update View.
Check Relations and References:

Ensure that the dimensions in the drawing are correctly referencing the model geometry. If the references are broken or changed, dimensions may not update correctly.
Re-attach Dimensions:

If dimensions were manually added to the drawing (not imported from the model), they might need to be re-attached to the updated geometry.
Check for Detached Dimensions:

Sometimes dimensions can become detached. Look for a red X symbol next to dimensions, indicating they are no longer attached to the model geometry.
Configuration Settings:

Verify if you are working with configurations and ensure the correct configuration is selected in both the model and the drawing view.
SolidWorks Settings:

Go to Tools > Options > System Options > Drawings and ensure Automatic update of views is checked.
Update SolidWorks:

Ensure you are using the latest service pack of SolidWorks. Sometimes bugs are fixed in newer updates.
