object editing in gp2 and gp1?

[Jacopo Nono]

Are the objects designed the same in gp2 and gp1?  The reason I ask - the Paul Hoad object editor is not working very good for me.  I have been having problems lately modifying objects.  I was wondering because if gp1 objects are like gp2, maybe someone can teach me something to make me more successful.
