Properties

Having created the standard and secondary standard; the properties need to be created or modified depending on the method of creating the Standard/Secondary standard. The properties manage the engineering criteria against the appropriate attribute for the relevant ASL object. The engineering criteria of the ASL objects such as STRFLT, Ladder are defined and managed by the Design Data Set (DDSE) which is owned by the APPLDA. The DDSE corresponds to an ASL element type which has a separate Tab for managing the values against the attribute property (Description field).

The Description field is a listing of the attributes against the STRFLT element. The DDAT stores the engineering criteria in the form of an expression, Real, Max/min or VVAL, it is this data in the DDAT elements that effectively parameterizes the assembly and what the rule checking engine performs its analyzes against. Indicated below are the expressions the 'Relationship between rise and going' DDAT element stores;
