Hi everybody,
I am looking for the syntax behind the buttons in the "AVEVA.Interaction.PrimitiveGallery." 
What I am trying to achieve is to create buttons for negative extrusions that have the attribute NAPPFLAG already set to different levels, so not set to -1.
Furthermore, I need the user to receive the "pop-up" in canvas window when clicking the buttons that allows for them to insert POSITION and SIZE of the nagatives.
