Assignment #3: Part One - Fusion 360 Tutorial

To begin learning Fusion 360, watch this tutorial and follow along.

Be sure to do the following:

  • When the tutorial says to use an SVG file, you can use this one.
  • Stop the tutorial at 28:40, or before the section on getting the file ready for 3D printing. We will go over this process in detail in a few weeks
  • When you are finished with the tutorial, go to File -> Export... and save your file as type "STEP File" or file extension .step. (STEP files are a standardized file format which are used to transfer your models between CAD software tool. They maintain the geometry you've created, unlike other file formats.)
  • DM me your final .step file as "A3_[name]_Tutorial".

Assignment #3: Part Two - 2D CAD Drawing of Mechanical Toy

Using your 2D hand drawing from last week, select a side view that has the most detail, and create a 2D drawing of it within Fusion 360. If there is a dimension you don't have on your hand drawing, you can go back to your original toy and take a measurement using your calipers. The goal of this assignment is to familiarize yourself with the drawing tools within the Sketch mode of Fusion 360.

Be sure to do the following:

  • Create a new Design in Fusion 360.
  • Create a Sketch on the Front plane.
  • Within this sketch, draw your side vide of your toy using the sketch tools. If there is a shape or type of line you need to produce and you haven't learned it yet, use Google and research what tool can help you achieve it. A couple of tools that may be helpful:
    • 3 Point Arc tool (for making a specific arc shape using the start, end and middle point)
    • Fit Point Spline tool (for making complex curves)
    • Fillet tool (for making an arc between two lines)
    • Trim tool (for cutting out specific sections of lines)
    • Offset tool (for making a copy of a line a specific distance away)
  • After you have completed your sketch with as much detail as needed to accurately depict your toy, click Finish Sketch.
  • Confirm the sketch looks accurate and if not, edit your sketch again.
  • When finished, go to File -> Export... and save your files as type DWG. (DWG files are an older file format originally for use with 2D CAD drawings. They are a great format for sending line drawings between programs and we will be using them with certain fabrication machines.)
  • DM me your final .dwg file as "A3_[name]_[toy name]" on Slack before the beginning of class on 9/24.

Below is an example drawing of the train toy. Feel free to include more detail than this as well.
