Week 8 - Challenge 4 - Coin Holder Design

Aim :

Create the Coin Holder Plastic component through the given Class-A surface.

Solution :

Draft Analysis :

We will create the tooling axis of the following component :

We have created the intersection curve as shown below :

Since all the walls are at 90 degree we will create the tooling axis normal to the direction :

Creation of B Surface :

We have extracted the surfaces of the following walls as shown below :

Now we will be trimming this surface as shown below :

Now we have created the side wall as shown below :

Creation of Base :

We have created two surfaces by extracting them as shown below :

Now we will untrim as shown below :

After this we have offsetted them by 2.5 mm .

We have trimmed it to achieve the following :

We have created the top wall as shown below :

We have added fillets as shown below :

Intial Trim

After trimming the intial wall we get the following :

Trimming it with the top wall :

Now we will create the outer flange :

We have extrapolated and got the following :

After this we get the following :

Now to get the final B surface we trim it with the others :

Creation of C surface:

We have created the following surface using multiple extract :

Using sweep command we get the following :

Creation of Fillets :

After creating the fillets we trim the B surface and the C surface :

Now we will join it with class a surface and use close solid body as we get the following:
