For the CNC Mill, we did a brake bracket. Although the plans were already laid out, it was still a learning experience designing it.
As you can see from this image, the upper rings needed to intersect tangentially with each line they came across. Since this was the first sketch, I needed to include the border of the upper rings, but not make them part of the existing sketch. To do this, I made them construction lines, which is why they are colored blue. You can also see that the lines are not curved around the upper rings, and instead meet at a vertex to change directions. This part will be cut off later.
The overhanging shape is cut off, making the lines intersect tangentially to the upper rings and curve with them. This process could have happened in more efficient way, but for me, this is the fastest way.
Overall, this individual CNC mill project helped me design things in inventor better. I also learned how to take a schematic and use it to create the object in inventor or a 3d modeling program. This was also the first time I had used the tangent tool.
