Week 11 - Project - A pillar Design with Master Section
Aim:
To create A pillar Design with Master Section.
Taken the Thickness of the component to be 2.5 mm from the master section
Class A surface:
Class A surface is a Styling surface or aesthetic surface get it from the styling team. we will design the plastic component by using the Class A surface as input.

Creating the class B surface:
Class B surface is to be creating the engineering features and offsetting the surface of class A. Firstly we will extract surfaces by using the extract command and from the class A surface. And if there are any patches we have to make it a smooth surface and finally get the complete boundary.

Creating the class c surface :
<!--[endif]-->
<!-- [if !supportLists]-->· <!--[endif]-->Class C surface is connected the Class A and Class B, For the class C surface, we need to create the entire boundary of the component by using the boundary command.
<!-- [if !supportLists]-->· <!--[endif]-->And also creating the best way for the tooling direction to manufacturing easily in an effective way.
<!-- [if !supportLists]-->· <!--[endif]-->By using the sweep command, we can combine them and trim the surfaces so we can get the completed closed surface body and draft angle given as min 3 degrees.
<!-- [if !supportLists]-->· <!--[endif]-->Before trimming the most important things join them all.
After the body has to be closed by using the closed surface in part modeling.
Tooling axis:
<!--[endif]-->
The tooling axis is formed by rotating Angle 1 about the x-axis, followed by rotating Angle 2 about the y-axis. Additionally, there is an Angle 1 rotation about the Z-axis, followed by an Angle 2 rotation about the X-axis to establish the tool axis.
In practical applications involving the removal of metal from the core and cavity, we require a center of the surface known as the tooling axis. To create the tooling axis, first, create dummy lines on a bush or hole walls and then intersect them, as shown in the figure below.
Designing of the dog house
<!--[endif]-->
The dog house is an engineering feature used in the plastic trim design. Dog houses are used as supporting features. Sometimes other engineering features like snaps; locators, etc. are mounded on them to increase their strength. The dog house is mostly used in automotive plastic and its main purpose is to help to avoid sink marks and saver of wall thickness. The dimensions of the dog house is 25x25x30mm and thickness is 2.5.
