Door Arm Rest Week 8 Challenge
DOOR ARM REST:-
AIM:-TO CREATE THE DOOR ARM REST WITH THE GIVEN THICKNESS OF 2.5mm AND GENERATE THE DRAFT ANALYSIS REPOR
FOR THE CLOSED BODY.
PROCEDURE:-
Draft Analysis
NOTE : In this model their is adequate draft is not provided on class a. So we have to communicate to styling team to
do changes in class A surface
SINCE THE CLASS-A PART IS ALRAEDY WITH YOU ALL WE NEED TO CREATE IS A CLASS -B SURFACE
NOW, AS WE HAVE BOTH THE CLASS-A AND CLASS-B SURFACES, WE CAN CREATE THE CLASS-C USING THE SWEPT
OPTION BY CREATING THE BOUNDARY OVER THE CLASS-A SURACE WITH RESPECT TO THE TOOLING DIRECTION O
WHAT EVER NEEDED.
IN THIS CASE, AS WE HAVE THE DOOR ARM REST, WE CAN MAKE SURE THAT THE DOOR ARM REST IS ALSO HAVING
A BACK SURFACE, IT IS DIFFICULT TO CREATE THE SPEPT ALONG IT. SO THE SWEPT IS CREATED USING THEREFERENCE SURFACE FOR THE BACK SURFACE.
TOOLING DIRECTION:-
The Tooling Direction is basically the direction that the mold pulls apart. The mold is built in two separate pieces, basically.
You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dyeline or the Tooling
Direction.
To create the tooling direction, from the class-a surface choose the appropriate plane and create a line normal to the surface
To make sure that the line created is a Tooling axis, view the tooling axis ina anormal view. If we can see the whole class-a
with no blind spots, we can say that the craeted line is the tooling direction or the DYELINE.
CREATING THE CLASS-B SURFACE:-
A Class-B surface is a surface which is not seen for. It accomodates the fits and fixtures on it. In other words we can also say
that th Class-B surface is a other side of the Class-A surface.
As the Designer states the thickness, we create the class-B surface by offsetting the required surfaces from the class-A
surface.
Create different geometrical sets for different parts while creating the calss-b surface so that we be able to identify or edit in
future if required. Also give appropiate names so that they could be easily identified.
Extract what ever needed from the class-a surface and offset them for the required thickness and extrapolate if required.
using trim, split and other different options and appropriae techniques we aquire the required output as class-B surface.
Make sure to join them.
CREATING THE CLASS-C:-
Swept is option we use to combine the class-a and class-b surface. The surface we create from class-a is class-c surface.
Visually the class-c surface is the surface which has been created from the boundary of the class-a.
Now by using the swept option which indeed has the draft direction option is been used and a draft angle of 3 degrees is
been given(with reference to tooling axis).
The resulting surface is class-c surface.
The Class-C surface and Class-A surface are Joined and then trimmed with Class-B to produce the required output.
A closed body will be created from the output(PART DESIGN>CLOSED BODY) which has to further deal with DRAFT ANALYSIS
DRAFT ANALYSIS:-
The Draft Analysis command enables you to detect if the part you drafted will be easily removed. This type of analysis is
performed based on color ranges identifying zones on the analyzed element where the deviation from the draft direction a
any point, corresponds to specified values.
RESULT:-
Created the Plastic design for Door ArmRest and added thickness to it and generated the Draft Analysis on a solid surface fo
Door ArmRest.
