Objectives :

Create the Door Trim Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

Creation of Tooling Axis :

To create a Tooling axis First we have to select a flat surface to extract only then we can provide a proper draft direction. Extract the selected surface untrim it and create a point on the center. Using the point create an axis system then make a intersection of the given class A with respect to the xy direction in accordance with the point created now create two line on both the end of the intersection using the line created create a bisecting line. Test the line wheather it clears the required drafft angle

DRAFT ANALYSIS OF CLASS A SURFACE

The created draft angle is clearing the required draft deg

Construction of class B & C Surface

Construction of class B surface

Extract the class A surface for the given thickness of 2.5mm inward
After extraction check the surface for patches
If any patches were found clear them first
Repair the surface using the suitable methods
Using join method in remove mode sub elements to remove remove the surface with patches
Then using disassemble seperate the surface into 4 domains
Now using boundary,extrapolation&trim command repair the surfaces

Construction of Class C surface

At First Create a boundry in the center part of the Class A Surface
Then using the sweep command create a sweep with the angle of 90deg and the boundary which we have created as the guide curve
Then to reduce error while making sweep create seperate boundaries and then sweep
so that it can clear the draft analysis
Join all the patches in the surface we have created
Join the created class C with class A
