Final answer:
The command that can be used to correct downstream issues that can occur when deleting reference geometry is the Update Feature References command.
Step-by-step explanation:
The command that can be used to correct downstream issues that can occur when deleting reference geometry is the Update Feature References command. When you delete reference geometry, it can cause issues with other features or dependent objects that relied on that geometry. The Update Feature References command ensures that any affected features or objects are updated to reflect the changes made to the reference geometry.
For example, let's say you have a sketch that is used as reference geometry for multiple features in a 3D model. If you delete that sketch, the features associated with it might become invalid. By using the Update Feature References command, you can resolve these downstream issues by updating the affected features to use new reference geometry.
