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

Aim: Create the rib for the door handle considering the design rules.

Tooling axis:

create point on Class A surface plane & create tooling axis on point & normal to surface (On surface method).

Creation of class B surface:

In this component Directly offset class A surface to 3 mm.

Repair the patches using multi section surfaces.

Creation of class C surface:

• Extract all the boundary of class A surface Separately by observing the complexity, then sweep them.
• Trim them together then we will get Class C surface.
• 

Then join class A and C.

Finally join Class A, B and C.

Convert the Class A, B, C surface to closed body.

Creation of ribs:

­we need to switch to part design workbench and then create a sketch according to the rib design with tooling axis as reference.

After creating a rib pattern, it with the help of rectangular pattern and give draft as 0.5degree and edge fillets as per the design considerations.

Draft analysis:

Given class A surface is having some defects, tried with different iterations by changing the draft angle.
