Task 1

My geometry is a sun with different levels of rays. I made it extruding the outline two times, one to 25mm and the other to 12.5. Then I made a sphere from the centre of the 12.5mm piece to the triangles and merged it with the base. After that, I deleted some of the triangles alternating in the big and small pieces. In the bigger one, I extended the plans of the triangles until they met and made a surface to make it one piece. Lastly, I merged the 12.5mm and 25mm pieces using the boolean union.

Task 2

For my figure, I used the shape I had of a semi-moon, and engraved and cut some shapes into it.

I made these shapes by using dodecagons of different sizes and some straight lines. After I drew the main dodecagons, I scaled and moved around the outlines of the three outer ones. After that, I drew some lines to cut parts of the exterior dodecagons around the main ones. Lastly, I drew some straight lines.

Task 3

I used the dodecagon of the A3 as a base for my building. I did a parable on one of the sides with an inclination of 65º and extruded it to a point 10 mm above the origin it to make a cone. After that, I made a polar array and combined it with another with the extrusion point in origin in order to create a more interesting shape. Lastly, I moved it 5 mm up and closed all the surfaces in order to print it more easily.

Fail 1

In my first try to print the figure I did not adjust the off set in the 3D printer right.

Fail 2

After adjusting the printer I realised that the supports made the figure not look how I wanted.

Task 4

To make my roof structure I first created the vertical elements by creating a 50cm slanted 1m truss with 5 diagonal reinforcements. After that, I distributed them along the roof making 5m gaps in between. To make the structure more rigid I created two other trusses in the back and front of the vertical trusses to tie them together. Lastly, in order to give the roof more support I created horizontal bars on the top.
