modify the custom L1 of an object using VB.Net

[Ender157]

when running custom python Tray the user complains about the way the length is changed.

I can get/set ALL the properties off the object but the parameters are not listed i.e. L1.

I can read the parameters but not seem to set them. any thoughts?

Using tr As Transaction = doc.TransactionManager.StartOpenCloseTransaction()
Dim Partx As Entity = tr.GetObject(res.ObjectId, OpenMode.ForWrite)
Dim Param As New ParametricPart(Partx)
Dim Params() As String = Split(Param.Parameters.ToString, ",")
Dim Parinfo As ACPUtils.ParameterList = Param.Parameters
Dim Info1 As ACPUtils.ParameterInfo = Parinfo.Item("L1")

Info1.Value = NLen 'input from user 2 points

Info1.Value = <your new value>
Param.UpdateEntity(partId, Parinfo)

This message usually means the selected items are not Plant 3D objects, have lost database connection, or the drawing is not opened in the correct project context. Do the trays with the error show Plant 3D properties in the property palette? Also, do they have the 'L1' parameter name?
