Hello, A client would like to add a new material to the standard SW database (apparently nobody uses 5052 Aluminum anymore). He reports back that you can modifiy values in the existing database but cannot add any. To add materials, you have to make a copy of the original database and use it instead. Is this a bug or was it designed to be done this way? If it is a liablity issue, why allow users to modify the original material properties? Is he missing something or "thats just the way it is". Thanks in advance Len K. Mar, PEng. E-data Solutions
