SMD keyword (class attributes)

The SMD keyword associates attributes with a class. The class definition must associate all of the attributes that will be used by any subordinate subclass. A subclass can only associate attributes that have been previously associated with the parent class. Element name Definition Description SMD Keyword UNCT Unique attribute ID Specifies the ID of an attribute defined in the UNCT dictionary. It associates the attribute with the class. For more information, see SMV keyword (attributes). Standard Designation Standard dimensional designation DIN or ASCII standard designation for attribute The Standard Designation and Attribute Name (from the attribute definition) appear next to the respective attribute value field in the Classification pane located on the Properties tab. Min Minimum numeric value Max Maximum numeric value Flags Not used, always 0. EX1 Not used. EX2 Not used. For example, the following lines define the Fasteners group (essentially a class without any attributes), add the Nuts01 class, and associate the ID, OD, and THRD predefined attributes with the class: Copy SML |Fasteners|FSTNRS| |Fasteners|FSTNRS| | 2 | | | !Fasteners Group SML |Nuts01 |NT |Fasteners|Nuts |Nts |nuts.gif| 0 | | | !Nuts Class SMD |-25011 |ID | | |0 | | | !ID attribute | SMD |-25011 |OD | | |0 | | | !OD attribute | SMD |-25011 |Thread| | |0 | | | !Thread attribute |
