The comparison table in the Update Manager also shows the geometric similarity between the part in the old project row and the one in the new project row ("Geometric similarity").[17]
This allows you to see at a glance, when checking an assignment, whether the assigned part in the new catalog version is geometrically identical to the previous one. A low similarity score indicates an assignment that you should examine more closely.
Described in detail in the chapter " Catalog Update with ERP Integration" – Resolving Assignment Issues with Update Manager (via Dashboard > Link Manager).
