Week 8 - Challenge 1 - Draft Analysis on a Fan Cover
1. Tooling axis
- Creating a postioned sketch on zx-axis and creating the projection line with intersect the 3D element .
- from the projectionline creating two line on the either sides and bisecting them on z direction.
- with the same inputs creating the projection lines on zy-axis.
- the resultant lines x-axis & y-axis are bisected again to get the final tooling axis.

2.Draft analysis
- Insert -> Analysis -> Feature Draft Analysis
- moving the axis to the tooling direction and locking it
