Hello,

What i am reading from your request is to have a hole in a part, then in an assembly place and constrain a fastener from the content center. then when the hole is updated the fastener would change to reflect the hole diameter change?

@priteshkumarvinchhi, welcome to the forum.

You can do this using the AddContentCenterPart function. Hope this helps, Curtis

Rename the CC part in the assembly browser, in order to stabilize the component name
Create a new iLogic rule ( if needed)
In the Model tree withing the rule editor, located the CC part and right click on it as shown
Select "Capture Current State Components.Add ...."
- I've selected the one using Designation in this example

It might take a bit as iLogic reads the CC database tables, but eventually it will give you the code to place the CC part
- Something like this:
- ```
Dim Hex_Nut = Components.AddContentCenterPart("Hex Nut", "Fasteners:Nuts:Hex", "Heavy Hex Nut - Inch","1/4 - 20")
```

You can then use that to create logic such as this where the user selects from a list, and the selected input is used in the AddContentCenterPart function

Dim oList = New String(){"1/4 - 20", "3/4 - 10"}
Dim oInput As String = InputListBox("Prompt", oList, oList(0), Title := "iLogic", ListName := "List")
Dim Hex_Nut = Components.AddContentCenterPart("Hex Nut", "Fasteners:Nuts:Hex", "Heavy Hex Nut - Inch", oInput)

Or something like this if based on the hole size as humistonandrew suggested.

Dim holeDia As Double = InputBox("Enter Diameter", "iLogic", 0.266)

Parameter("Bottom Board", "Hole1Diameter") = holeDia

Dim Hex_Nut As ManagedComponentOccurrence = Nothing

If holeDia > 0.75 Then
	Hex_Nut = Components.AddContentCenterPart("Hex Nut", "Fasteners:Nuts:Hex", "Heavy Hex Nut - Inch", "3/4 - 10")
Else
	Hex_Nut = Components.AddContentCenterPart("Hex Nut", "Fasteners:Nuts:Hex", "Heavy Hex Nut - Inch", "1/4 - 20")
End If
