I usually use the generic IC from core and set its number of pins to match the number of connections I need. That creates the appropriate pins,their connections and the pads in all three views and can then cut and paste around them to get the part running. The one annoying thing about it is the connection terminal pads are set to 0 height and width. That means that Inkscape won't select or move them, so the first thing I do is change the width and height to 10 for all the terminal rectangles so they will be selected and moved when moving a connection.
