Class objects, creating/destroying?

[cbrf23]

So I'm learning a little about class objects, and I defined my own class and wrote some code to set values and all that.

From what I understand, the way I have written my code below, the system doesnt actually create my class object BPFeature until the line

Set BPFeature = New ClaBPFeature

I might be wrong on that, but from what I've read thats the way I understand it to work.

So if thats when the object is created, I'm wondering, when does it get destroyed?

Do I need a line of code to destroy the object and release the memory it was using, or does it get destroyed automatically at the end of the subroutine in which it was created?

for example, in the subroutine below, does the object BPFeature still exist and is it still using memory when the subroutine ends? Because if thats the case, if I run this subroutine enough then I would just be wasting system memory...

Sub testClass()
Dim rngItem                 As Range
Dim BPFeature               As ClaBPFeature
 
Set rngItem = Intersect(Range("A:A"), Selection.Rows.EntireRow)
Set BPFeature = New ClaBPFeature
    With BPFeature
        .Item = rngItem.Value
        .InputDescription = rngItem.Offset(0, 1).Value
        .Nominal = rngItem.Offset(0, 2).Value
        .HighTolerance = rngItem.Offset(0, 3).Value
        .LowTolerance = rngItem.Offset(0, 4).Value
        .Method = rngItem.Offset(0, 5).Value
        .Zone = rngItem.Offset(0, 6).Value
    End With
    If ThisWorkbook.Sheets("INPUT").Range("H2").Value = "Metric" Then
        BPFeature.Metric = True
    Else
        BPFeature.Metric = False
    End If
End Sub

It's is destroyed when the variable goes out of scope, which occurs at the end of the sub.

Thank you shg, I thought that was how it worked because it dissapears out of my locals window when the sub ends, but i wasnt 100% sure.
