SOLID EDGE ST6 - MODELING A SPIRAL CASING

Edit 1 (2016-12-27) : New renders done in Blender added I stumbled upon this pdf drawing a long time ago when i was looking for small horizontal francis turbines. It was a part of a French exam and as I stared at it I wonder what it would take to build the 3D version in Solid Edge ST6. So I decided to make it as a modeling tutorial and I hope you will enjoy it. The videos are uploaded on my youtube account. NB: I am not the original author of the print so the credits goes to whomever deserves them. That's why I will not uploaded the parametric model, but only the step and stl files.
