Please point out my mistake.

Public Sub SCBKL2()
I'm trying to scale mulptile block about their insertion point. Could
someone please point out my mistake?

Dim objDrawing As AcadBlockReference
Dim varEntityPickedPoint As Variant
Dim InsertionPoint As Variant
Dim dblScaleFactor As Double
Dim objScale As AcadBlockReference
Dim objSelSet As AcadSelectionSet

Set objSelSet = ThisDrawing.PickfirstSelectionSet
objSelSet.SelectOnScreen

On Error Resume Next

InsertionPoint = objDrawing.InsertionPoint

dblScaleFactor = ThisDrawing.Utility.GetReal("Enter the scale factor: ")

'Scale the object

For Each objDrawing In objSelSet
Set objScale = objDrawing.ScaleEntity
objScale InsertionPoint, dblScaleFactor

Next objDrawing
objSelSet.Delete

Exit_Here:
Exit Sub

End Sub

 

InsertionPoint = objDrawing.InsertionPoint
objDrawing hasn't been set yet !! Delete this line

This should work

For Each objDrawing In objSelSet
InsertionPoint = objDrawing.InsertionPoint
objDrawing.ScaleEntity InsertionPoint, dblScaleFactor
Next objDrawing

If it's only blockreferences you want to scale, you should filter
your selection set, so no other type of entity is picked up.

 

Thanks
