Week 9 - Project 1 - Door Trim Lower with Engineering Features

Aim:
To create a final plastic product (class B + class C) from the given class-A surface.

Theory
Class A-Surface:
A surface type Design mode by the class A surface Designher with the separate Design softwave like Alias and that Design is taken as a input for create it as plastic model. Basically if is created as Aesthetic surface and outer surface which is Basically visible to the customer.
Class B-Surface
A surface is which is opposite to the class A surface which it have some distance wahilch is considered as thickness it will created as Design and Engineering Aspects.
Class C-Surface
The surface is created to connect the class A amd B surface as per Thickness

Draft Analysis
1. The Draft Analysis is important for all the Plastic mode because all the plastic modelo undergoes manufacturing by the moulding and extrasion for the moulding the smooth Releasing of core and cavily we made the Draft angle about 3 degree.
2. In this model first we Analysis the draft by creatting the Tooling axis.
Tooling Axis:
Tooling axis is the Axis line which is the straight line based on this line as considered the core and cavity moves.

Procedure:
Step 1:
Import the class A surface mode
Step 2:
Extract the plain ;surface from the given class A surface.
Create the point and create the Axis line.
Step 3:
check the Draft analysis According to the Tooling Axis line by placing the compass in the line.
Step 4:
Create a Class B Surface By offset the class A surface According the Thickness given in the requirements.
Step 5:
Work on the class B surface if any damage is there patch it.
Step 6:
create the class C surface wahich is from the class A surface and the touches the class B surface.
Step 7:
Trim the Joined surface with class B and make sure it is complete plasitc surface and closed surface and create the solid model.

Draft Analysis Report:
The Draft Analysis considered when the compass is placed and select the surface the colour changing is happen. The permitting Draft angle is 3 degree
                                                     colour code
                                                                3 deg - Green
                                                                0-3 deg - Red
Based on this colour change we can assure that the product made as correct procedure.

Draft Analysis to be made for
1. Class A surface

2. Final component made as closed surface.
