Design - Shaft and using "fx" string

[Anonymous]

I need to pull dimensions from my shafts created with "Shaft Generator", (i.e. Main Dia, overall length) so I can auto populate the materials filed in my drawings.  Everything I have tried so far has failed.  I am not sure what the parameter names are or where to find them for the dimensions I need.

Hey There 

First figure out which parameter(i.e user or model or renamed etc ) you want to pull in to the drawing 

Please provide me little more details like image or something

Design Accelerator creates quite simple assembly structure – one assembly with parts only.

DA assembly and parts always have the property set "FDesign",
its internal name is “{6CD3181A-0C7D-41aa-BDB3-969A9B72E1BB}”.

Shaft sub-assembly component should have the attribute “Data“ from the attribute set "FDesign".  It contains all important information about shaft component in XML format.  You should be able to find all information you need in this xml string.

The following vba sample prints this attribute value to the immediate window.

Sub Explore_DA_Shaft_Assy()
 
    Dim oAsmDoc As AssemblyDocument
    Set oAsmDoc = ThisApplication.ActiveDocument
    Dim oAsmDef As AssemblyComponentDefinition
    Set oAsmDef = oAsmDoc.ComponentDefinition
   
    Dim oOcc As ComponentOccurrence
    Set oOcc = oAsmDef.Occurrences.Item(1) 'shaft subassembly
 
    Dim oAttr As Inventor.Attribute
    Set oAttr = oOcc.AttributeSets.Item("FDesign").Item("Data")
   
    Debug.Print oAttr.value    'print XML data
   
End Sub
