Bezier Curves and Circles - Loft Beveling Along a Path

The video embedded underneath explains a more complicated way of "creating a tube around/from your curve" - but if you want to bevel any other curve along your basic curve, it is hepful.

To "tube your curve" easier -

  • in your curve object data (editor window curve icontab)
  • uncheck "Front" and "Back" in the Fill area of your Shape panel
  • then increase Depth and Resolution in the Bevel Area in the Geometry panel
  • - this will create a closed circle around your curve.
