​Hello community!

​I am currently working with 3DEXPERIENCE (ENOVIA) and trying to automate the creation of product structures. My main goal is to import an Excel file containing CAD references along with their relative 3D positioning (the instance matrix/coordinates). I want to use the "Import" feature in the Engineering Release app so the system automatically loads the items and builds the assembly with the correct 3D positions in the space.

​However, I am running into a roadblock: I cannot find the specific column or attribute for the 3D positioning (such as V_matrix, Position Matrix, Spatial Location, etc.) to map my Excel data.

​I have checked the Attributes Browser under the instance types (like Physical Product Instance and CAD Extension For Exposing Instance Information), but I cannot seem to locate the exact field required for this import.

​Does anyone know where this specific column is hidden, what its exact display name is in the latest versions, or if there is a specific setting/extension I need to enable to map it during an Excel import?

​Thank you so much in advance for your help!
