How can I create a ECExpression that take de pipeline diameter?

Question

Hello Masters of OP ; ) 
 I&acute;ve to create a way to put in a field the name of my pipe system. 
 the tag names here are formed by: 
 PRODUCT: PpPp 
 NUMBER: 1234 
 SPECIFICATION: SSS 
 DIAMETER: DD 
 and, if existis, INSULATION: Ii 
 For example: 
 A pipe of cooling water (WaCl), with the number 2325, in the carbon steel specification (CS2), with 20 inches of nominal diameter and not isolated. 
 This results in: WaCl-2325-CS2-20". 
 ok, well I belive that is an possible solution: 
 this.SERVICE & "-" & this.NUMBER & "-" & this.SPECIFICATION & "-" & this.NOMINAL_DIAMETER& "-" & "&acute;&acute;" 
 to be edited in the EcExpression in the NAME properties of the Iso Sheet class (i want to show this on the isometric sheet). 
 Well, obviously, its not work at all... 
 so... I need some help, please... 
 
 and oh! thanks a lot!

Hello Dennis, 
 Thanks for sharing the details. From above query what I understood, you are looking to include NOMINAL DIAMETER along with inch sign. Please refer below wiki article which explains the Regex and parser to a format with inch sign. 
 this.NOMINAL_DIAMETER & """" & "-" & this.SERVICE_NAME & "-" & this.NUMBER & "-" & this.SPECIFICATION 
 You may change the order to make it working correctly.

Hello Dennis, 
 This is mainly because RegEx only validate the properties which are available on its class. Here SPECIFICATION is not available, hence missing. 
 For any property to cascade from different hierarchy to certain class, require different expressions. Try below expression to get SPECIFICATION to be applied on ISO_SHEET class. 
 this.LINENUMBER & "-iso-" & this.NUMBER & "-" & this.GetRelatedInstance("PIPING_NETWORK_SYSTEM_HAS_ISO_SHEET:1:PIPING_NETWORK_SYSTEM").SPECIFICATION
