Week 1 (CAD)

    For the first lesson of the new module, CP5070, I have been tasked to create a digital sketch of a keyring using Fusion 360 as a refresher. But before we continue, you need to know what exactly is Fusion 360. Fusion 360 is a CAD/CAM/CAE tool that can be used to develop products and works on both Mac and PC. This assignment serves as a refresher for what I learned the previous semester about Fusion 360.

    When you first open up Fusion 360, it would open up a new project. Any past projects can be accessed by clicking the 9 square blocks on the top left of the screen.

    To start off, you need to click create and select the 'two-point rectangle'. The dimensions I chose for the keyring is 65mm by 25mm as can be seen below.

    By giving the rectangle an offset of 2mm and filleting the outer corners by 5mm, the sketch should look as shown below.

    After which I clicked on 'create line' to draw a line across the sketch and used the dimension tool to define the distance between the top of the keyring from the line as 7mm. Using the line as a guide, I created a circle on the line with a diameter of 5mm using the center diameter circle tool.

    

    By clicking on the 'finish sketch' button, it is now ready to be turned into 3D. By clicking on the sketch and using the 'extrude' tool, I gave the keyring a breadth of 3mm, while not extruding the circle, creating a hole for the ring of a key chain. 

    To create a border, first I went back to the sketch and selected the border of the keyring and extruded it by 1.5mm, and creating an offset of 3mm, so this border would sit on top of the previously extruded product.

    

This is what it looks like together.

    To smooth out the hole in the key ring, I selected the edge of the hole and used the 'fillet' tool to round off the edges.

    After this, I decided to do something different. Instead of creating my name on the key ring, I wanted to see if I could make a 3D model of the USS Enterprise since my group is named after the ship from Star Trek, so I gave it a whirl.

    I first sketched 3 circles in a line the middle one being slightly bigger. After which I extruded the one of the two smaller circles into cylinders and moved it into the edge of the keyring and filleted the front to create a rounded surface and used the tool 'revolve' on the back section of the cylinder and deleted the bottom parts of the cylinder to give it a similar look from the one from the movies.

    Now that the first of the two nacelles as they are called is completed, I mirrored it over to the opposite side so that they would be symmetrical. Next, the middle circle was finally extruded to form the body of the ship that connects the nacelles to the saucer section of the ship.

    The rear of the cylinder was also rounded off using the filleting tool. Next, to create the connections between the nacelles and the body of the ship. First I sketched 2 rectangles and extruded them and moved them above the keyring platform using the offset tool. Next I filleted the edges of the rectangles to give them a slim profile.

    Next a thin rectangle was sketched and extruded at the front of the body to create a platform for the saucer of the ship to rest upon, with its edges filleted and smoothed over to make it look similar to the movie version.

    Finally, for the saucer section, a circle was sketched, extruded and offset to the correct height to rest perfectly on the platform. To make look more like a saucer and less like a cylinder, the filleting tool was used to round off the edges. 

    It may not be screen accurate, but I would say it looks quite similar!

    In the future, my group will be using Fusion 360 more often and from this experience, I cannot wait for the next time to play around with Fusion 360. The HTML file of the above design is below, Enjoy!
