Week 8 - Challenge 3 - Coin Holder Design
COIN HOLDER
AIM: to make a model from the provided class-A surface.
INTRODUCTION:
Class A surface: a surface made by the designer which is given as an input to the plastic modeler to work on. It is aesthetic surface and the outer most surface.
Class B surface: a surface below a certain thickness from the class-A surface is class-B surface. This is the surface that contains engineering aspects of a model.
Class C surface: a surface that joins class-A and class-B surfaces is class-C surface.
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 ANALYSING:
- Draft allows for the component to release from the mould, most parts or applications require a minimum of 0.5 to 1 degree draft angle and 3 dgree draft angle is widely used as per the norm.
- Change the material mode to customize mode before moving to the draft analysis.
- Insert –analysis-feature draft analysis
- Defining the draft direction Select draft analysis from the tool bar and click on the compass symbol and pull the compass from the right side top corner of the workbench and place it on the component where want to do the draft analysis. ‘W’ of the compass and tooling axis should be aligned on the same line.
- Once the compass is aligned with the tooling axis click on the lock symbol and drag on the surface we will get a wrong mark then select that point a table will appear it shows the draft value on the table we can adjust the draft value and analysis it for all the edges and surfaces.
- By clicking the on the surface and using the flipping tool we can assign the Flipping direction, the color of the surface change as per the flipping direction .
- Analysis under running point and move the mouse on the surface and it will show the details of the surface deg direct at each and every point of the surface.

CONCLUSION:
- Hence the Coin holder plastic component through the given class A surface and created the required Tooling axis and performed the Draft analysis on the model and also for the solid model.
