User System Defined Attributes (USDA)

By sub-typing assemblies based on UDETs and connecting them to customized variants of attributes through USDAs, is a way to put restrictions on attribute values for certain assembly types. This means that if any of these attributes have USDA definitions with a limited set of allowed values, only these values are presented in drop down menus when edited from the Properties function. As in the example below assemblies of type ASM1 allow only the following working locations (i.e. restriction on ASWLOC attribute), 'Cutting shop', 'Hall A', 'Dry dock B' and 'Painting shop'.
