GrabCAD
This is a demonstration on how to make a mobius band using autodesk inventor 2013. For purposes of clarity the profile used is a thin rectangle similar to what was used in defining the original mobius concept. However the same principle and methodology can be applied using any 2-D profile.
The part was made using a series of lofts at 10 degree intervals, the more intervals you use the smoother the end connections will be.
