Computer aided design

This week I learned about 2D and 3D design tools, types and how to use. Assignment this week is design final project using 2D and 3D tools.

2D vector illust using Adobe illustrator

This is my final project, micro biosphere illust.

how to illust it

I placed the sketch I wrote previous week.

I traced it with geometry tools.draw square like this.

draw circle and line like this.

And I select colors with color panel.

And I wtite texts.I can select size and font with text panel.

I had a problem of constitution of layers. Edit mode layer was made automatically, before I notice it,then constitution of layers became messy.

2D Raster illust using GIMP

This is my final project concept image.

original image by NASA Earth Observatory, IMG_8370 by ManNg

• First, I put free photos.
• I selected earth. select by color > revers select
  
• I cut and paste to another photo image.
• I draw on that image by pen tool.
• I change color of earth image to fit color of base image.

2D vector illust using inkscape

For making decal to use Fusion360 3Dmodel, I used Inkscape.

I exported it and import to Fusion360 as decal.I I lost the svg file. Only png remains.

3D model using SolidWorks

This is simple model of my final project.

3D model using Fusion360

First, I learned how to use Fusion360 from my tutor and a member of Fablab kitakagaya. I made a spinning top as a tutorial.

Next, I tried to model a housing of my final project in detail.

I used user parameter to be able to change tickness of board at one time.

This model can be separated part by part, I can image how to assemble it.

3D model using grasshopper

This is bacteria's cube image. It will be in micro-biosphere, my final project.Bacterias clean water. So,the area touch with water should wide. I want to make its form like soap babble (efficient filling form) and its face like fractal, so I tried grasshopper.(In fact, I have not succceed.)

how to model it

• I used plugins, weaverbirds, Topologizer and Exoskeleton. I downloaded these and set in components folder (file > special folders > components folders).Under my setting(windows and not Administrator), I had error so I should cancel block (properties > attribute > cancel block).
• I connected components as shown in the image below.
  

It is not bad, but I want to make baranches more thick and when I setted the thickness parameters of branches, it become error.And these shape　are distorted, so it will not be mounted neatly.I am trying new model.

Appendix:3D model using Antimony

I used Antimony to plan form of cube's joints. But difference components does not work I expected. And I could not array a combined object.・・・I think it is cooler that I write script directly, insted of making components to calculate like addition or division.

how to edit video

The original video was too long so I shorten it. I used Light works.

• import video and fast-foward.
  
• Add audio.
  
• Add credit text.(right click > Add title)
• Cut and export(move blue start and end mark)

Impression

• Fusion360 is great! It's learning cost is very low compared to what I can do. Especially, I like history function and user parameter. I feel I should experience (not how to use tool) modeling and assembling to use it efficiently.

• Grasshopper vs Antimony

  • grasshopper is not easy to understand how to use. It has many components and information.so I can make things that I do not know how to model it.
  • Antimony is easy to understand how to use. People who use processing to draw might be familiarize. But it is not easy to model something. Little bit Troublesome. And information about it is limited. I want to re-use scripts made by other people. I want many people to use Antimony and transmit information, and improve Antimony.
