Geomagic Design X Tutorial Reverse Engineering a Blisk

In this video, I show the use of Geomagic Design X Software to reverse engineer a blisk.  A blisk is a turbomachine component comprising both rotor disk and blades. It consists of a single part, instead of an assembly of a disk and individual, removable blades.  I show how to use the cylindrical method of creating 3D mesh sketches on one of the blades.  Multiple radial cross sections are created and used to create a surface loft.  Additional surfaces are created then trimmed together to make a solid body.  The blade is copy/rotated to make the blisk.  The use of 2D mesh sketches are also used to create features.
