I submitted this as a bug but apparently should be an "idea"...crazy. When using CREATE2D and you have your centerlines turned on, CREATE2D does not create lines for fittings such as 90 elbow, 45 elbows, etc. but they centerline does show up on the 3D parts. It should be ADDED that CREATE2D will create a line for these types of fittings, otherwise you're left with two perpendicular lines not connecting.
