We have a sample called “Material Table Editor”. This sample illustrates how to extract the material library from Solid Edge and populate an Excel file. You can add new materials, deleted existing entries, or modify the existing values. The sample also has an import capability to take the contents of the Excel file and add them back into the Solid Edge material library. Note that the import will overwrite all current Solid Edge materials, so appropriate backups should be made.
This sample can be found at: “<SE install folder>\Solid Edge STxx\Custom\Material Table Editor”
