The document tested is a part or an assembly.

Bracket the operation if a property, with a certain value, does not exist in the document drawing of the document part or assembly.

The statute of the value turned over can be selected ''Equal to'' or ''Different from''. The test can be performed on numeric or alphanumeric values.

For numerical values or date we can choose''Superior or equal to'', ''Superior with'', ''Inferior or equal to'' or ''Lower than''.

Example : If the property ''Material'' in the document drawing exists with the value ''NiMo 28'' then the operation is applied.
