Bom Item (Find Numbers) used to drive WTProduct structures

Bom Item (Find Numbers) used to drive WTProduct structures

There is a documented process for driving Windchill Find Numbers from a Creo assembly. The issue is that creating an assembly component parameter for every component in the assembly is time consuming and open to human error. Also because it is a parameter created for each component in the assembly you can enter different integer values for each Find Number even though the CAD part is the same. i.e 4 x M6x25 bolt could have 4 different Find Numbers when you only want one driving the Windchill product structure

 

Fix,

 

Solution 1 - At the assembly level allow the start assembly model to contain the component parameter used to drive the Windchill Find Number just like any other part or assembly parameter and ensure that the integer value entered gets used for every instance on the same part in the assembly

 

Solution 2 - Allow the repeat region report index to be used to drive the Windchill product structure Find Number.

 

Currently if you have an assembly of 100 parts you need to create the assembly / component parameter 100 times ensuring that you name it the same and that I have. The effort has gone into Windchill but not Creo

At the 2017 Liveworx there was a good presentation from the folks at JLG on how to automate this with a Jlink app (Code & Candy: The Sequel (or CAD-Driven eBOM Structure) ). I agree PTC should consider implementing some form of fix, but in the short term it appears to be a good work around.

 

Windchill 11 you can also propagate the Find Number and Line number information from the Product Structure down to the CAD - "If you modify the Line Number or Find Number attributes in the Uses tab on a PTC Windchill part information page, you can now choose to update the same attributes on the usage link for the accompanying CAD document when the part is used to perform a reverse build of the CAD structure ." Though we have found this has some unintended consequences if you don't have a 1 to 1 CAD to Product structure.

We have the same issue.

I like solution 2 but together with my idea about this issue. Please Vote Also for tha idea!
