As you are aware, the Symbol Editor will not let you save a schematic symbol without shape information. I was designing a very simple (rectangular) part with 68 pins (34 per side). I note the hatched area that comes up when you start the SE and see (though experimentation) that pins line up touching this area. The problem is, that only rarely can I get a rectangle shape to match up to the hatched area. Almost invariably, either the rectangle "shrinks" to well inside the hatched area or the hatched area increases in size. In either case, the pins don't touch the rectangle shape (which I think they should). They are either "short" of the rectangle or, worse, is when the rectangle shrinks, as it obscures the pin names. I have tried messing with the Grid settings, but it is very hit and miss. Again, what am I doing that I shouldn't be doing?
