Week 8 - Challenge 4 - Coin Holder Design
Aim: Design a coin Holder From Class A surface.
For that we follow the previous Procedure.
Creation of tooling Axis
1.Intersect the model with the plane perpendicular or to an axis system.
2 Extend the lines which are perpendicular to the plane.
3.Again intersect the model with another plane and extend the lines perpendicular to it.
4. Create a bisecting line by bisecting option in Line definition.
5. Rename it as Tooling Axis.


Procedure for creating B Class surafce
Side Walls
- Extract the side walls with no propagation in extract option.
- Untrim them.
- Extrapolate the walls with point continuty of distance 20mm.
- Trim the walls to get the required shape
- Offset those trimmed walls with thickness value.

Top & Battom Surface
- Extract the surfaces separately and untrim them
- Extrapolate the surfaces with required distances.
- Offset them with thickness value
- Trim them for required shape
- Measure the fillets, calculate it and create filets.










Proceder for create C class Surface.
- Get the boundary lines of Class A surface separately
- Smooth the curves with a smooth option as boundary lines have a lot of vertices
- Sweep the curves with tooling as as direction in Sweep option.
- As both lines do not intersect, extrapolate them with a certain distance.
- Trim the surfaces.




Procedure for creating Closed Body
- Join the Class A and Class C surfaces.
- Trim those joined surfaces with Class B surfaces
- Go to Part Design and insert a Body.
- Create a closed surface.
