Blog Entry 3 + Practical 2

Week 5: Manual Drawing & CADD

Manual Drawing:

At the beginning of the lesson, our lecturer Dr. Noel gave each of us some blank A4 size paper. Not gonna lie, we were quite clueless at first when we first received the paper. Slowly slowly, we were introduced to one-point perspective and two-point perspective drawing. To me, it looks quite difficult to draw when I first saw the slides. However, when Dr Noel guide us through the drawing step by step, I feel that it is actually quite manageable. 

We drew a one-point perspective drawing with only one vanishing point as shown below:

Next, we moved on to draw a two-point perspective drawing that has 2 vanishing points.

After learning these two drawing method, i went home and tried drawing a coffee machine by myself using a 2 point perspective drawing method.

Overall I feel that perspective drawing is very tedious but it is good at the same time as it helps us to create a more realistic object as compared to 2D drawing method. But definitely, 2D drawing is so much easier to draw 😑

CAD - Computer-aided Design:

After learning manual drawing, we were taught how to draw a sketch using Autodesk Fusion 360 to create a model. I tried to create a keychain and photo frame on my own by following the step-to-step guide. I would say that it is not easy at all...😩 I redo the keychain and photo frame a few times and these are the final products as shown below:

At the same time, our group has also decided on what our final product would be. It is the odour absorbing gel stored in the 3D-printed container.

One of our group members, Sook Yee helped us move the physical sketch to Computer-aided design by using the Fusion 360.

So, the odour absorbing gel would be stored inside the container as shown in the picture above. The holes on top of the container act as airways for the gas to be absorbed into the gel and also prevent the gel from falling out if the whole container topples over.

Learning reflection (week 5)

This week, I've learned how to draw using the one-point perspective, two-point perspective drawing techniques, and also CAD drawing. I feel that it is a useful technique to learn especially when we are doing product design. These techniques help us to illustrate the product that we want to show to the audience in a better format.

In a nutshell, I feel that this week is a very fun and enriching lesson although I dont really love drawing, but it is still fun to navigate the software around to create a product model that we want.

Practical 2: Cardboard Joinery

For practical 2, we were tasked to build something with cardboard that consist of at least 6 different types of cardboard joinery. Our group decided to build a house and I have no idea where this idea comes from but we just thought of it 😂.

So the materials that we used are:

- 2 cardboards

- scissors

- ruler

- pen knife

- cutting board

- scotch tapes

- glue

To start off, we sketch out the design of the house that we want on the iPad, and then we decide on what type of joinery to use, and the dimensions of the house.

Then, we transfer all the measurements onto the cardboard and start to cut them into pieces.

These are the dimensions and types of joinery that we decided to use :

. The "ground" -  A piece of cardboard (25cm by 25cm)

. The fences - 4 Cardboard pieces with gaps cut out on the top of the fence (6cm by 25cm); attached using the 'tabs' method.

. The walls -  3 Cardboard pieces with (4cm by 4cm) squares cut about 3/4 height as windows (walls - 10cm by 20cm); attached using the 'tabs' method 

. Front wall - (10cm by 20cm) Cardboard with a rectangle (4cm by 9 cm) cut out as a door; attached using the 'tabs' method.

. Roof - Cardboard piece (30cm by 22cm) and placed on the top of the 4 walls; attached using the 'tabs' method. 

. Chimney - A piece of cardboard cut out as a rectangle, then rolled up to make a cylinder (4cm by 10cm); cut into the 'flange' shape and attached it using brass fasteners.

. Windows - Cardboard cut into small squares (4cm by 4cm); joined together using the 'slot' method, then slot into the square slots on the walls.

. Wind Vane - Cut 2 small cardboard pieces (1cm by 2cm) and joined using the 'slot' method, then attached using a 'skewer' through the roof.

. Door - Cardboard (7cm by 9cm) and folded at the 4cm mark to form a 'L-brace' to simulate the door opening and closing, then attached to the front wall using a 'brass fastener'

and yea tadaa!! this is our final product:

Key takeaways:

From this practical, my main takeaways are the important skills of how to make use of cardboards to make different types of joinery and where to use it. Although cardboards are cheap and the easiest material, but it is the most useful material to use for prototyping as it can be folded into the different shapes that we want. I've also learnt that we should always cut parallel to the flute so that it is easier to cut.

I feel that it is quite important to actually plan out everything before we come for practical. My group did not plan out everything beforehand and that leads to us not having enough time to build out the prototype and it is quite rushed towards the end. But overall everything was carried out smoothly, our prototype looks not bad to be honest hehe:) We worked quite closely as a team and everyone knows what to do. Maybe this is why our end product looks good.😁

yea i guess thats the end of this blog. Thank You for reading my blog I hope you guys enjoyed reading it! :)
