Also, adding on to my previous comment. It is impossible for ANYTHING to be 1 dimensional. Everything, EVERYTHING is 3 dimensional. As that you cannot draw anything that has an infinitely small line. Even a nanometer counts as 3d. (No matter how small a line is, it is 3 D even on paper... Fun fact: Paper IS 3 dimensional.) -Given from a 8 year old child, still in primary school.- <--- Sorry if I have grammar or spelling errors.
@kogut9 (Sorry everyone for responding to something with a -11 comment.) BA is not 1D. As 1 D is a line. It is 2D otherwise, all squares, triangles and other flat objects will be considered 1D. If that was true it'll mean that the current two dimensional shapes (squares triangle octagons etc.) will be counted as 3 dimensional shapes.
