Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)
REPORT:
AIM:
- Create the Drill Handle
- Create the rib for the Drill Handle considering the design rules.
- Create the Screw boss for the Drill Handle considering the design rules.
Commands Used:
- Point,Line,Extract,,Trim,Extrapolate,Offset,Edge fillet,Boundary,Sweep,Join,Multi section surface,Close Surface,Extrude,Plane,Circle,Intersection.
Procedure:
Class-A Surface:
- This is the given Class-A Surface of a Door Handle.
Tooling Axis:
- To create a tooling axis, a point is plotted on the curve of the Door Handle.Using point-direction method a line is created in the Y-direction.This line is Known as Tooling Axis
Draft Analysis:
- Draft Analysis is performed on the class-A surface.
Class-B Surface:
- To Create class-B surface, directly offset the class-A surface upto 3mm.
- As the class-A surface is directly offseted, one of the patch is missing on the offseted surface.
- The missing patch is created using Multiple Section Surface.
- Join the multi section surface and the offsetted surface to form class-B surface.
Class-C Surface:
- Class-C surface is created using boundary,sweep,extrapolate operations on the class-A surface.
- Then trim the unwanted surfaces to create class-C surface.
Join Class-A surface & Class-C surface:
Final Trim:
- Unhide the class-A & class-C join and class-B surface.Then trim the unwanted surfaces to form Door Handle plastic component.
Close Surface:
- Using close surface,a solid model of the bumper is created from the plastic comonent.

Draft Analysis:
- Draft Analysis is performed on the Solid Model.
RIB Creation:
- Rib is designed according to the principles in the below figure.
- Thickness,t=3mm.
SCREW BOSS Creation:
- Screw Boss is designed according to the principles in the below figure.
- Thickness,T=3mm.
- W=0.6*T
Draft Analysis:
- Draft Analysis is performed on the Solid Model.
Tree Structure:
Conclusion:
- Tooling Axis & Solid Model of the Door Handle is created.
- Ribs and screw Boss are created on the B-surface of the Door Handle.
- Draft Analysis is performed on the class-A surface and solid model.
