LC DCG

An interesting problem solved in SolidWorks

Every day students ask interesting questions and sometimes even pose problems which take a bit of time to solve. So when a DCG student wanted to draw a tapered helical spiral and google wasn't throwing up any help, a lot of heads started banging together and eventually a solution was found. Instead of using the traditional sweep feature to extrude a circle along a helical spiral which would result in the same diameter spiral Fig 1, a loft between varying diameter circle profiles using the centre line profile of a helical spiral was the solution Fig 2 & 3.
