change value of parametrized iproperty

[dibujocad]

Hi everybody, I'd like to change the text included in an iproperty value through VBA.

The problem is that the value of this iproperty is linked to a parameter of the part and I wouldn't like to break this link.

I mean, if my value is "#15 mm ST52", I'd like to change it to "#15 mm ST44".

The value "15" is linked to a parameter of the part, but the text "ST52" isn't.

I know that it's possible make changes without losing the link manually, clicking the symbol "fx" next to the iproperty value. However, if I directly change the value through VBA, I lose the link

Would it be possible to change the text through a macro without lose the link?

Expression is a value from the iproperty that you can get or set. Here's a sample:

Dim oDoc As PartDocument
oDoc = ThisDoc.Document 

'Get/Set property:Description
oDescription = oDoc.PropertySets.Item("Design Tracking Properties").Item("Description")

oDescription.Expression = "=<Thickness>mm is my expression"
