Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

First need to join and make a single surface as CLASS A SURFACE,

After create a point on surface and make axis system and intersect with with plane and CLASS A SURFACE and need to create sketch with that intersect ,

project the edges and bisect that projected straight curves and name it as TOOLING DIRECTION

create a geometric set and name as CLASS B SURFACE and offest the CLASS A SURFACE to 2.5 mm and join the surface with out openings

Make a geometric set as CLASS C SURFACE and Take a boundary of CLASS A SURFACE and Sweep with reference surface feature with boundary and angle is 90degrees and appox length is more than thickness

 and Trim it with CLASS B SURFACE to make closed.

Create a new geometic set and name it as RIBS and Make a sketch on bottom side and draw a line according to Standards and extrude it to 12.5mm with tooling direction and 

give thickness 1mm and draft the edges where required with 0.5degress with base extract and assemble with MAIN BODY.

Create a new set and name it as SCREW BOSS and create a sketch bottom side as done at RIBS and 

extrude it to 15mm and Draft it to 0.5 degrees as it is minimum and Assemble it to Main Body.
