iRule Remove Custom Property

[jbwaiteG7526]

In an iLogic rule, I can create a property in the "Custom" tab by simply defining it :

      iProperties.Value("Custom", "NewParam") = "value"

I can not find a method to Remove/Delete/Erase that "NewParam" from the custom tab.

In particular, someone had edited the default part template and had a "LENGTH" field on the custom tab.  I have a rule that checks many parameters and fields to make sure they are correct for passing to our post-processing program and I would like the rule to check if this "LENGTH" field exists and then it completely remove it.

'define list of custom properties to delete
Dim MyArrayList As New ArrayList
MyArrayList.add("LENGTH")

'define custom property collection
oCustomPropertySet = ThisDoc.Document.PropertySets.Item("Inventor User Defined Properties")
'look at each property in the collection
For Each oCustProp in oCustomPropertySet
'check property name against the list you want to delete
If MyArrayList.Contains(oCustProp.name)Then
'delete the custom iProperty
oCustProp.Delete 
Else 
'skip it
End If
Next

Hi @jbwaiteG7526 

Here is another example.

Also just as a tip, you can search and ask programming questions of this type on the Inventor Customization forum too:

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Try
ThisDoc.Document.PropertySets.Item _
	("Inventor User Defined Properties").Item("LENGTH").Delete
Catch' catch error when property is not present
End Try

Hi @jbwaiteG7526 

Just another note on the subject.  That "Length" custom property may have been made automatically by Inventor, if within the Parameters dialog of that document there is a parameter named "Length", and someone checked the checkbox option for that parameter in the "Export Parameter" column.  When you check that box, it 'exposes' that parameter as a custom iProperty automatically for you (creates a custom iProperty with the same name and value as the parameter).  Also after that option has been checked, more options become available under your right-click menu for that parameter, where you can further customize how you want that custom iProperty to be formatted.  If this is the reason that custom iProperty exists, you can probably just uncheck that option in the parameters dialog box to get rid of that custom iProperty.  Just thought you should know, if you didn't already. 🙂

This was one we had made sure to check.

The "LENGTH" was coming in from a "template" that was made a while ago in the default ".ipt" template.

Thanks for your response.
