total NEWBIE needs a push in the right direction

Yo you all.  what I trying to do is design items for example a piece of jewelry using Blender.  From there send the file to be cut on a 4 axis cnc machine.  I don't even know what that process of drawing in Blender is called, 3D modeling ??  Is there anyone that can point me in the direction I want to ??  sincerely thank you, Cary
