Week 8 - Challenge 3 - Coin Holder Design
Objective:
To create the Coin Holder 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.
Methodology:
In this model we have focused on the following things:
- Tooling axis
- Draft analysis
- Class-B surface
- Class-C surface
- Making a solid model from surface.
Following tools were used to reach the final step:
- Extract
- Un-trim
- Trim
- Extrapolate
- Offset
- Edge fillet
- Boundary
- Sweep
- Join
- Close (part design)
Draft Analysis:
As we intersected to proceed, we observed that the side walls are not given any draft. Hence, we assume the axis normal to the base surface and parallel to side walls. This surely will create problems because a minimum draft has to be provided.

Draft Analysis
Class B Surface:
We have divided the entire model into base, side walls, inside side walls and outer flange and worked on them one by one.
Everywhere we follow same procedure i.e. extract, un-trim, extrapolate, trim and offset.
First base, then side walls. To avoid confusion, we trimmed both together and made them one. Also the fillet was given.
Class B Surface
Class C Surface:
We will first get the boundary of the class-A surface and sweep it with reference surface option.
Solid Body:
After joining Class A, Class B and Class C surfaces together, we used Closesurface command in part workbench to create the solid body.
