Week 9 - Project - A pillar Design with Master Section

As the part file is a class A surface, therefore, we first have to create a solid part with the help of Class A.

First, we create a tooling axis using the intersection method.

Now we created a Class B surface by using the following tools:-

1. Extract

2. Disassemble

3. Untrim

4. Extrapolate

5. Trim

6. Split

Then we created a Class C surface by using the sweep tool

Then we joined Class A, Class B, and Class C surfaces

Dog House with key hole

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. Dog houses are subjected to draft analysis to prevent breakage of the component during ejection from the mold cavity. Dog house and other engineering components are built on B-surface.
