How to determine the direction of a wire out of a symbol pin in schematic

Hi,

I would like to write some SKILL to add wire stubs and labels to a certain symbol instantiated and selected in a schematic cellView.

I think I have the basics in place, i.e. reference to a selected cellView with geGetSelectedSet() and then dig into its instTerms and

from there to each instTerm~>term~>pins~>fig~>bBox, then transform it to the bBox relative to the cellview with dbTransformBBox()

basically:

cv = geGetSelSet()

foreach(instTerm cv~>instTerms

instTermBbox=car(instTerm~>term~>pins~>fig~>bBox)
instTermBboxInCv=dbTransformBBox(instTermBbox
                           car(inst~>transform))

)

code might need some polishing, especially when extracting the right item from the list returned by - for  instance - inst~>transform or ...~>bBox.

So from here, I can use schCreateWire() and schCreateLabel() to add a wire and label.

The point where I'm puzzled is: how to determine the direction of the wire? How do I determine the position of the pin within the shape?
I am thinking of using the symbol's bBox to infer whether the pin is on its top, bottom, left or right side, however when I query the bBox of the selected shape, I get something weird.

I have placed a single vcvs on an otherwise empty schematic. I select it in the window, and then call cv = geGetSelSet().

cv~>bBox returns the following:

(((-0.48125 -0.2125)
(0.91875 0.26875)
)

The strange thing about this bBox is that the y coords (I'm assuming they are the second elements in each tuple) are more or less correct, i.e. they correspond roughly to the bottom and top pin extremes, whereas the the x coords are further away from the boundaries of the symbol.

So I'm wondering what this means and how to interpret it.

Thanks for any help,

Michele
