Cone-Shaped coffee filter.
Coffee filters are made from crepe papers which are produced in paper machine which has a large steamheated drying cylinder that is fitted with a hot-air hood. The cylinder is then sprayed with adhesives to stick the crepe panels together to form the coffee filter.
The creped panel of the coffee filter together with its cone like shape allow the coffee to have a smoother flow from the funnel to the coffee pot. Flattened Plan View

The filter is first measured when it is completely flat to understand itâ€™s basic dimensions. The filter is then pushed open into itâ€™s functional position. The new length of the filter is remeasured and using pythagoras theorem, the triangles produced by the theorem allows me to measure the different heights from the mid-point of the filter.

This exercise brought allowed me to construct a 3D box and explore different perspectives and ways of viewing the box. Other exercises include workspace arrangement and settings adjustment etc.
This exercise brought allowed me to better organise and label my work through the use of layers. The diferent line colours on the screen represent the different layers used for each object/curve. Deleting each layer will also remove all objects of that colour.
