2. Computer Aided design¶

This week we were assigned to work on 4 designs using 4 different programs to produce 2 2D design & 2 3D designs

AutoCAD¶

The first program I used to do a 2D design is AutoCAD, you can download it from here

For short, AutoCAD is a technical drafting program that you use commands to create whatever you want

I wanted to do sanemi’s sword guard from Kimetsu No Yaiba anime

First I started doing a part of the sword guard using line tool (L) shortcut

Then, rotating it along the center creating the basic sword guard shaped (R) shortcut

Then, I offset the each line to create a thickness of the sword guard (O) shortcut

Then, I added a circle to meet the sword guard design (C) shortcut for circle, (R) shortcut for rotating

Finally, I added a circle in top so I can use the design as a key chain if I cut in the laser cutter

Note that the dimensions are not in real world scale

Illustrator¶

The Second program I used to do a 2D design is Adobe Illustrator, you can download it from here

I had fish for lunch this day thus I was thinking about fish farming, therefore I wanted to do a tree of fishes representing the fish farming :)

First, I started by creating a half circle for the tree based using ellipse tool (L)

Then, I created the tree main branch using pen tool (P)

Then, I change the stroke to match a vector tree branch shaped

Then, I added more branches making the tree more dynamic

Then, I started creating the fish body using ellipse tool (L)

Then, I started merging shapes together, subtract shapes, copying, and editing till I get the fish shape

Then, I selected the fish and made it a brush. Press F5 to show brushes menu then the small + in the bottom then choose scatter brush

Then, double click on the brush icon that will appear to change its settings, modify the setting to make scatter, change in size, and change in rotation when drawing using the brush

Finally, use the brush to paint in the tree trunk and it is ready to go and export

Sketch Up¶

The First program I used to do a 3D design is Adobe Illustrator, you can download it from here

I wanted to create a vase

First, I created a rectangle for reference (R) shortcut

Then I added a line in the middle to make a symmetrical design (L) shortcut

Then, I drew the vase elevation using arc tool (A) shortcut

Then, because I created the middle line before I easilly mirrored the side (M then click cntr) shortcut for coping tool, (S) shortcut for scaling it to -1
