Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)
DOOR HANDLE
AIM:
To Create the Door Handle with function of class B surface and class C surface and also with the creation of Ribs abd Screw Boss also perform the Draft analysis on the final surface and these perform by the class A surface.
Objective:
Create the proper Tooling Axis.
Creates the Class B surface correctly.
Creates the Class C surface Correctly.
Then makes the Design as the Closed Surface.
Creates the Ribs On the Closed Surface.
Creates the Screw Boss on the Closed Surface.
Atlast the Draft Analysis done the Final surface.
Tools Used:Catia V5
Intoduction:
In this Challenge we crates the Door Handle Design using a given Class A surface with the creation of class B with the thickness of 2.5mm and Class C surface and also creates the Ribs and screw boss after the creation of class B and C surface.
Class A surface:
The Class A surface was given as Catpart File and in the class A surface the tooling axis is created.

Creation of Tooling Axis:
The Tooling axis was created by the intersecting and bisecting method and the line created at the center point and the line named as the Tooling Axis.The red dotted line is the tooling axis
.
Creation of Class B surface:
The Class B surface was Created by the offsetting with the thickness of 2.5mm and then offsetting some sub elements missing so make them the closed surface and extrapolate 1 or 2mm thickness with end surface to make trimming with class A and Class C surface.

Creation of Class C Surface:
The Class C Surface was created by the Class A surface with taking Boundary over the Class A surface and sweep option is used by the boundary created and is done the class C Surface was Created.

Creation of Class A and Class C Surface:
The Class A and Class C was created by the joining by the process of Class A nad Class C surface.

Creation of Class A+C and B Surface:
The Class A ,Class B and Class C surface was created by the trimming of the Class A+C surface with Class B surface.

Creation of Closed Surface:
The closed surface was created on the Final surface.

Creation of Ribs And Screw Boss Design:
The Rib was Created on the closed surface and the line was drawn on the extract part and then it is pad and thicken option was done.
and measurement for ribs is taken from the given option.
The Srew boss also created on the closed surface and the two circle was drawn on the extraction part and then circle was pad on the surface and measurement of screw boss was taken from the given option.

Draft Analysis on the Final Surface:
The Draft Analysis was done on the final surface with the draft angle of nearer to the 3mm so it shows the angle above 3mm on all the surface.
