Week 7

 1. What is Computer-aided drafting and design(CADD)?

• It is a software to draw and design physical components or to layout processes. 

• Allows accurate calculation of dimensions and more advanced software. 

• Estimate accurately different kinds and the amount of materials used or the length of manufacturing time, which facilitates budget planning. 

2. What is Fusion 360?

(Figure 1: Logo for Autodesk Fusion 360)

• Fusion 360 is a powerful All-In-1 tool.

• Helps to connect the entire product development process comprising design, engineering, and electronics.

•  Manufacturing into one cloud-based platform.

First Activity:

In the first activity, we are tasked to use Fusion 360 to create a keychain for ourselves.

Key Takeaway:

1. The Sketch function, which is used to create a shape. For example, in this activity, we made a rectangle from this sketch function and  added our names on the keychain.

2. Filleting. We used this function during making our keychain , by rounding out the corners of the rectangular keychain, to make the keychain more appealing as well as the hole on the keychain.

3. Cutting. We used this function to create a hole in our keychains.

4. Extruding. which we used to set the thickness of our keychain, and our imprinted names on the keychain.

Here, take a glimpse at our group members’ work ❗❗❗

Second Activity:

Key Takeaway:

1. The Vertical/Horizontal constraint is used to make a line either horizontal or vertical. In this activity, we used this to make the line we drew earlier to land horizontal. 

2. The Coincident constraint, which we used to set the center of a circle to an endpoint of a line.

3. The Tangent constraint, which is used to make a line tangent to a circle. We used this to make a line tangent to two circles.

4. The Mirror function, which is used to mirror an object. We used this to mirror the line that is tangent to the two circles that we drew, making another tangent line on the opposite side of the circles.

5. The Concentric constraint, which we used to make a circle share the same center with one another.

6. The Trim function, which is used to remove unwanted parts of our sketch and some of the constraints.

Here once again, take a glimpse at our group members’ work ❗❗❗

Last Activity: (Synchronous Activity)

Finally, our last task is to design and draw the various parts that can be put together to form a photo frame for a 4R photograph which its sizes follow 102 mm x 152 mm.

Therefore, we came out with these dimensions after our discussions.

1. Front frame: 102mm x 152mm

2. Middle frame: 144mm x 166mm

3. Transparent acrylic sheet: 102mm x 152mm

4. Back part: 114mm x 166mm

Here are the sketches by me and the group members:

Reflection for Week 7:

Ambrose:

This week, I have learned how to design a product by using a software called Fusion 360, basically to design a 3D product using a computer-aid application. I thought it would be very cool if we designed it using the computer-aid application since I saw some footage from behind-the-scenes of some movies. At first, I struggled to design the product assigned by Dr Noel because I was unfamiliar with the functions of the software. Soon, I found that I was able to follow all the steps given in the instructions and I tried to get familiar with the functions in the software. If I encounter any problems with using the software in the future, I may refer to my group members to seek for help and we can learn together well and efficiently.

Joshua:

Creation using 3d modelling software is not something I'm very used to, but through learning some of the basic functions of the software through the guidance of my lecturer and the online materials to create some basic objects, I feel excited to create and further use this resource in the future.

Yongjie:

Week 7 we learnt how to use Autodesk Fusion 360! It was fun to experiment on the tools to make a 3D product. We made keyrings and it was super fun! We could design to our likings and I'm satisfied with my end product. Next we did another product and it was quite confusing to make at first, but with the help from friends and Dr Noel we were able to complete it. After the lesson we were tasked to make different parts of the photo frame and I did it quite efficiently and it was quite easy. I even found out about other tools such as render where we can change the looks of the product.
