2. Computer Aided design¶
During the first and the second day of week two, I have experimented various 2D and 3D software. The programs that I have used were:
2d software: Adobe Illustrator and cuttle.
3d software: Tinker cad and Solid works.
1) Adobe Illustrator¶
Adobe Illustrator is a software that is used to design custom shapes, icons, posters, drawings, typography, and complex illustrations.
First of all, open the program.
At the left corner select create new.
Select the type and the size of the page (I have chosen A4)
A blank page will appear. Then, select the pen tool which is located at the left in the toolbar.
Draw a line in the bottom
Pen tool is a flexible tool, you can draw any figure using it. (I drew a square)
Then draw a triangle above the square. (The roof)
Then draw a small rectangle inside the square using the pen tool. (The door)
Then draw a small square inside the big square (the window). After that, Select the window you drew and press alt and drag it to the next side to duplicate it (The second window).
Select the ellipse shape from the toolbar which located in the left to draw the door knob.
Using the pen tool draw the lines inside the window.
Now its time to color the shapes. First, select the triangle shape and in the left side of the screen select fill and choose the color you want.
Do the same process to color the rest of the shapes.
To add a text, select the T icon in the toolbar at the left.
And here is the final shape.
To export the house, select file.
Export - Export as screen
Browse the location of the exported file, and then select export artboard.

Increase the repetitions to 73.
Using the pen tool, draw a line from the edges of the polygon to the circle (do this to all of the four edges).
