Modification of Material Properties after Pre-Processing

It is possible to change the properties of the materials in a database after the pre-processing. It is not possible to change the material type of a wall or building after the database has been pre-processed. Such changes would require recomputing the pre-processing.

Any pre-processed database can be opened like a normal database. The difference is that most functions are deactivated. The properties of the materials can be changed via the menu Edit > Materials used in databases.
