It should be repeated: Modern Astronomy defines the Constellations to be areas of the sky. ALL of the sky is divided up into patches, called Constellations by the IAU. Historical constellations in those patches of sky were used to name the patches, BUT there was NEVER a line drawing connecting some of the stars into a shape which was AGREED to BE the constellation. Many examples exist in which the same stars are part of different "shapes".
Which drawing you use depends on your cultural roots. Roman constellations are different from (ancient) Greek ones. Here are the patches:https://en.wikipedia.org/wiki/File:C...gular_plot.svg
You can draw any shapes you want and call them anything you want; car, cart, spaceship, Enterprise, NCC-1701, or Oceana Basílio .....
