Week02-Computer-Aided Design

Checklist

  • Modelled experimental objects/part of a possible project in 2D and 3D software
  • Shown how you did it with words/images/screenshots
  • Included your original design files

This week’s Fab Academy assignment is divided into four parts.

  1. 2D Design
  2. 3D Design
  3. Rendering
  4. Source files
1、 2D Modeling with EasyDiffusion

This is an AI drawing software that I deployed and ran locally. It can create a drawing by simply providing an adjective. (It seems like today AI is not in a great mood; even the cloud is crying.) EasyDiffusion EasyDiffusion

2、 2D Modeling with photopea

This is a web-based version of Photoshop, and I will use it for bitmap image drawing. I started by using the Pen tool to draw a cloud.

3、2D Modeling with AutoCAD 2024

This is a software by Autodesk, where I used the SPL command to draw a cloud pattern. AutoCAD AutoCAD

4、 3D Modeling with SketchUp

This is Autodesk software. Since SketchUp can directly import CAD’s DWG format files, I imported the cloud pattern into CAD to create my final project. SketchUp SketchUp

5、3D Modeling with Tinkercad

This is also Autodesk software, but it is free. During the usage, I found it not very user-friendly for me; it seems more suitable for children. Tinkercad Tinkercad

1.3 Process of Modeling my Possible Final Project

1、 2D Modeling with Inkscape

I downloaded a raster graphic from Google and converted it into vector graphics using Inkscape. Choose file > import > Make, to convert a raster image into a vector image. Inkscape Step 1 Inkscape Step 1 Choose the file you want, then click “Open.” Inkscape Step 2 Inkscape Step 2 Choose Path - Trace Bitmap - Modifying parameters - Apply Inkscape Step 3 Inkscape Step 3 Inkscape Step 4 Inkscape Step 4

a. Troubleshooting
Set English Environment
The first unexpected problem I encountered was changing my Inkscape Chinese version to English version so that I could communicate with my tutors and classmates at Fab Academy. Inkscape Troubleshooting Inkscape Troubleshooting Inkscape Restart Inkscape Restart Inkscape Restart Inkscape Restart After the change, restart the software.

2、3D Modeling with Fusion360

a. Import the 2D cloud Drawing
Fusion 360 supports SVG format, so the diagram I just created using Inkscape can be directly imported and used. INSERT - Insert SVG Fusion360 Step 1 Fusion360 Step 1 Insert from my computer… Fusion360 Step 2 Fusion360 Step 2 Select your file and Open Fusion360 Step 3 Fusion360 Step 3 Choose one of your working surfaces Fusion360 Step 4 Fusion360 Step 4 Choose OK Fusion360 Step 5 Fusion360 Step 5 Finish sketch Fusion360 Step 6 Fusion360 Step 6 Use the shortcut key E to Extrude Fusion360 Step 7 Fusion360 Step 7 In the end, I used the Fusion 360 backtracking feature along with OBS to record a video showcasing the modeling process of my final project.

3、 Rendering

I used the built-in rendering animation feature of Fusion 360, which is more convenient than using screen recording software on the computer and then dragging the model. Select “ANIMATION” and set the view accordingly. Fusion360 Animation Fusion360 Animation Select PUBLISH Fusion360 Publish Fusion360 Publish Choose the parameters you want. Fusion360 Parameters Fusion360 Parameters Select the desired save location and save. Fusion360 Save Fusion360 Save This is the cloud rendered using Fusion 360.

1.4 Systematically Learning Fusion 360

Before this, I had used Fusion 360, but I didn’t learn it systematically. So, I believe I have many shortcomings. This time, I will undertake a systematic learning approach.
