Computer Aided Design (CAD)

Week 1 : Nametag making !

1. I made a sketch !!

2. Selected the correct plane to start out my sketch

3. I then mapped a rectangle w the dimensions of 65mm by 25mm 

4. I selected the offset tool, and offset the rectangle by 2mm

5. I selected the fillet tool and filleted the 4 corners, and put it at 5mm

6. I drew a line, turned it into a construction line, and then used the sketch dimension tool to define a line of 7mm

7. I selected the middle of the created line, and then used the circle tool with diameter of 5mm

8. I used the text tool and used it to type my name " Haziq :) "

9. I put in the final touches and readjustments, and finished the sketch, and heres how it looks like!!

10. I extruded the base and borders by 3mm and this was how it looked

11. I hid the bodies and made the sketch visible. I extruded the border and name by 1.5mm 

12. Using the same selected areas, I extruded it, by another 3mm, and final product !!

13. Unrelated but i made one for my girlfriend too :))

Here is the embeded Fusion 360 file !!

Reflection on CAD reflection !!

Personally, I think this tutorial was a good refresher as it has been awhile since i have done CAD, hence we this refresher was useful. I thought it would be simple, but after not doing it for so long, I completely forgot how to work Fusion 360, and now I am fully aware now that I have to actively use this application every once in awhile and I will be able to be fluent in using Fusion 360. 

 Week 2 : Handphone stand !!

For this week, we had a friendly competition in which we create a handphone stand, and the best design gets their item laser cut, and gifted over the holidays. Personally I would love to win it but my idea is not original nor ground breaking, However, it is functional, and in my opinion thats all thats matters. Now I will show you how I created this item, step by step !! 

Step 1 : Setting parameters

Parameters are an amazing tool to use, to keep my product consistent, and it helped me set certain dimensions and angles and helped me to make edits on my final product.

Step : Drawing the first leg 

1. Firstly I made a rough outline, making sure that I use the perpendicular tool on some of the sides in order to get perfect right angles on corners which it will look nice

Step : Extruding 

2. Using the extrude tool, I selected the main body, as well as the 3 rectangles (tabs) and extruded them to the dimensions of the ply thickness, 0.125 inches. 

Step : Selecting a second plane for the second leg

3. Using the offset plane tool, under the construct tab, I had offset the plane by 145 mm (height parameter) and selected that as the plane to work on the second leg

Step : Projecting the second leg

4. In order to ensure everything is symmetrical and identical, a simple tool we can use is the projection tool ( shortcut key P ) and by selecting the first leg, I was able to project a splitting projection of the first leg. Not only did this save me so much time, it also ensured everything was identical and there was no mistake to be made

Step : Extruding the second leg

5. Using the same parameter, I extruded the second leg, with thickness of ply parameter (0.125 inch). Thus I now have two identical leg pieces for my handphone stand,

Step : Sketching the phone tray

6. This part was tricky as there were many planes and the sketch was getting confusing. This part took many tries of trial and error but eventually I managed to get the right planes to be projected. After that I used the rectangle tool to draw a rectangle. The overhangs are measured using the parameter ( border = 15mm ) 

I also used the constriction tool, to snap the ends of the rectangle to fit snug into the sketch.

Step : Extruding the tray

7. Using the same thickness parameter, I extruded the tray, except for the area in which the tab will fit in order for it to be assembled.

Step : Sketching the backboard

8. This was not as tricky as it used the same trick as forming the tray. The overhang is measured at 15mm (border parameter) and I also used the constriction tool to snap the edges snugly into the sketch. The plane was also simpler to identify and pick as it was a straight plane.

Step : Extruding the body

9. Similar to extruding the other parts, I selected the correct faces ( all faces except the tabs ) and extruded it to the dimension of  the ply parameter ( 0.125 inch ) 

Step : Creating a support piece

10. Again, getting this plane was a hard task as I was struggling to make it work. Eventually I was able to, by selecting the flat side of the back. After that I used the offset plane tool, and moved the plane by 5mm into the leg, hence the selected plane is in the leg.

Step : Sketching the support piece 

11. This part was understandably easy as I was basically required to draw a rectangle on the  plane, snapping the sides of the rectangle to the edges of the two legs. However, I like things to be symmetrical, hence using the middle point tool, iw as able to centralise my rectangle, making the distances proportional. 

Step : Extruding the piece and cutting

12. As done previously, I extruded the piece by the parameter of ply, and rotated the product around to see if it was of correct dimension. However the problem is that  the piece does not come with the holes as seen in the second picture. One tool that helped was the combine tool. Selecting the leg as the target body, and the support as the tool, and using the cut option, the holes were created.

Step : Final product

13. This is the final assembled product which can be seen to look very boring and flat. Thus I took the time to "beautify" my handphone stand !!

Step : Beautification ( filleting )

14. Not only is it to beautify, its also for safety purposes. For this step, I decided to fillet the sharp edges, and this made it look nicer, and also safer to use! :))

(This design was made parametrically)

Reflection: 

I feel that this activity was very demanding in the sense that we had to design a whole product. Although my product may seem simple, I was very proud of it because it was out of my scope to make. However the use of parameters made this easier to make as if i made a mistake in dimensions, i was easily able to change it using the parameters. However this activity also showed me how much of fusion360 i am unfamiliar with, and that i can take advantage of for everday use.
