In an FME translation from a polygon geodatabase feature class to a DGN I am trying to place a label in the top left corner of a box. I have tried using CoordinateExtractor to find the coordinates of a corner (then 2DPointReplacer and TexAdder to add text to this coordinate) but this works on the number of the vertex, which unfortunately isn't constant as not all of my boxes are quadrilateral. What I need to find is a way to find the upper left vertex. Does anyone know how to do this?
I think you are almost there: If you post your workspace (or screenshot would be easier to follow)
What I think you are missing is the BoundsExtractor for your polygon (rather than the vertices)
