how to get material, centroid in ACIS

Hello

I am now working on converting data by reading ACIS (.sat) format.

This is the first time related to opencascade, so it is difficult to find a way to check the data that can be checked on the cad assistant.

The shpe-related data was imported, but in the case of material and centroid, they do not know how to import it.

Thank you for letting me know the sample source code.
