Let's say I want to draw a complicated shape which will be used as a component, like an antenna for example. Let's say I want to have it in a sort of library, so I can use it many times whenever I want.
First I tryied to draw the antenna as a footprint and link a component in my schematic to it, like we do for any chip. But I was not able to draw it because it's not possible to draw copper filled shapes in Allegro Package (Or I haven't found how to do so). So I drew it with etch lines but I get DRC errors. So I think I am doing it the wrong way.
So here is my question:
In Allegro package, is footprint only for drawing pins, or can we draw somehow complicated shapes connected to different pins?
 

If this stil is an issue, give me a 1:1 dxf of the drawing and point to where You wish the "connection pad" should be. If I understand You correct this is actually no problem, but this way i could do a little guide for You :).
 

Depend on the complexity, you can draw a shape in package but i would consider draw this shape for a padstack.
It is easier ti cerate this shape in a brd (the shape manipulation is not really easy in a dra; exemple: you can not "z copy" with an offset in dra) then export it in subdrawing, import in dra and save it in ssm format.
Then you can use it to create the pad.
