Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)

• DRILL HANDLE DESIGN 

                         AIM : To create the rib & screw boss for the Drill Handle.

• Tooling axis

1. Ensure the class A surface is properly joined
2. Analyse which direction is suitable for tooling axis
3. Extract the surface, create the point & intersect with class A surface
4. creating the line with point-point reference on bothsides 
5. Finally created the biscecting line with help of line 1 & line 2 & point to get the final tooling axis

• Class B surface

1. Offset the class A surface in 2.5mm in proper direction
2. Once offset is done some patches are missing
3. Then missing patches are obtained with the help of Multi sections, join & extrapolate commands

• CLASS C SURFACE

1. Create seperate boundaries from one vertex to another vertex in the class A surface
2. In sweep command with draft direction 3 degree was given to the boundaries with the help of tooling axis
3. In sweep command with reference surface 90degree was given to the boundaries
4. Then extrapolated the edges & trim it
5. Join the Class A & C surface together
6. Finally closed suface is obtained with the trim command

• Sketch for Ribs

• Sketch for Screw Boss

• Analysis for Rib creation

1. Both ribs are cretaed based on th design rules
2. Positioned sketch was created. Extrude & thick surface commands are used as per the rib design rules
3. After providing the draft. Boolean operations are used to add it to the body
4. finally fillets are given.

• Analysis fo Screw Boss

1. Both Screw Boss are cretaed based on th design rules
2. Positioned sketch was created. Pad & Drafted with the Screw Boss design rules
3. After providing the draft. Boolean operations are used to add it to the body
4. Fillets are given.
5. Finally using the translate comand to created the second screw boss

• Draft analysis on Class A surface

1. Ensure the view mode in material
2. Use the compass to define the new current draft direction & place it on the Tooling axis & lock it
3. Click the Class a surface it shows the Green colour area it satisfies
4. In this Class A surface some surface are not satisfied. So it needs to correction in the Class a creation team.

• Draft analysis on Final component

1. Ensure the view mode in material
2. Use the compass to define the new current draft direction & place it on the Tooling axis & lock it
3. Click the final componet it satisfied with the proper draft angle. If it not satisfied use the Analysis under running point tool & correct the values of an draft angle
