Getting Started with Fusion 360 Part 4 - Cut Holes, Remove Material from Objects and More!

Learn to use Fusion 360's solid operations, specifically the object cut operation, in order to interact different models with each other and to add detail to your models!

FULL FUSION 360 BEGINNER PLAYLIST

In yesterday’s video, we talked about some solid modeling tools inside of Fusion 360 that can be very helpful for creating various shapes. In today’s video, I wanted to talk about some ways that we can remove material, cut holes, and make various kinds of adjustments to shapes to make them look certain ways inside of Fusion 360 using the cut operation.
To do this, you need to understand the way that most tools work inside of Fusion 360. By default, when you create a 3D shape with a tool, it gets created as a new body. This means that it’s getting added into Fusion as a completely new, separate object – not interacting with anything else inside of your model.
However, most tools have a toolset that not only allows them to create new bodies, but also allows them to interact with existing shapes in a way that gives you more options.
For example, let’s say that we have our cylinder here. Let’s create a sketch object in the center base of this object. Now, if we extrude this object up, you’ll see that it automatically turns red. The reason for this is that Fusion 360 is picking up that this object is intersecting with another body and has therefore decide that in this context, we might want to use our second object to modify our first object. There are several ways that you can do this, but in this case, you can see how this second object got set to “cut.”
This means our object will remove material wherever it intersects with any other objects that it touches. This can be a very precise way to cut holes inside of objects.
This doesn’t only work on flat surfaces like the top of our cylinder, but also on curved surfaces like the edge of our cylinder.
The cut operation is also available when two objects intersect each other, like if we were to draw a sphere and a box. We could use this to remove part of the box where the sphere intersects.
Another way that we can use the cut operation is by drawing profiles, then using 3d tools to create shapes that we can use to cut away material. For example, let’s say we wanted to cut a recess n the face of our cylinder. What we would do is create a sketch on the vertical axis of the profile we wanted to cut into the object. We could then use a tool like the revolve tool to extrude that in a circle, and set it to cut to create our recess.
This is much more advanced, but you could also project a path on a form or a shape, then use it to extrude/remove material along a more complex shape as well.

Hi everyone! I'd love to hear a bit about how you've used the cut operation in your models - let me know in the comments below! :)

This is only part 4 of the getting started series and it probably doubled my knowledge of Fusion 360!! I did what most hacks/hobbyists do, started using Fusion 360 and googled what I needed to know, making a ton of mistakes along the way. Not to mention wasting a ton of time with trial and error. And although I gained marginal skills using Fusion 360, I decided to go through this series and I have palm-slapped my head dozens of times! I wish I knew about you and this series in the beginning!! THANK YOU for your contribution. I'm a fan now big time!

Been wanting to learn how to make models for a long time and finally decided to do it. Found these videos and I've found them to be exactly what I've been looking for. Thank you for taking the time to make these for everyone. They're a very good combination of length, detail and structure.

In 10 mins this guy has taught so many useful stuff.. Great Work!!

[anthonycampos]

Thank you so much. I've been trying to reach myself how to use fusion 360 for a few months and this is one of the better tutorial on fusion ive seen.

Don't use keyboard shortcuts because even if you say what the command is, newer users don't know what it does, looks like or functions like yet so it makes it more difficult to follow along

[konixtwenty]

Wow your tutorial is so straightforward and clear. I just love it. I listened to other tutorials and they just confuse you by being overly complicated for no apparent reason. Thank you very much

[stormbytes]

Another winning video! Justin if I might make a suggestion, what beginners are lacking is a concrete way of applying all these terrific skills and techniques to an actual instructor-led project. This would solidify the understanding of how the tools work and commit them to mental "muscle" memory. Just a thought. Keep up the terrific work!

For anyone unable to see the 'cut' operation after extruding, it's because you haven't specified dimensions for the rectangle sketch. Use the 'Sketch Dimension' tool, keyboard shortcut D to define dimensions and after that, the revolve will show the 'cut' operation.

[ljunq]

I think it would be helpful to see the sketches expanded while you were doing this to see the new sketches you're creating in the list. Do they persist? Can you reuse them?

I've learned in 10 min what I couldn't in hours ... Thank You ...
I Subscribed with out doubt ...
Thank You again and Please keep us on a loop with everything you do ... 👍

[poppabear]

You sir, simplified and solved a problem I was working on for a couple days.. Thank you so much! it was so easy, I just overlooked adding a sketch on another plane then making my cut.. you're freaking awesome.

[ceelo]

Hey thanks for the help! Just started with Fusion and needed a hand with the cut tool.

[NicDaddy]

Thanks man! I know this is an old video but you just saved me so much time and effort!

[veesoho]

Amazing! Id love to see it in a spiral and how to precisely control the cut in a spiral on a cylinder .. much like a screw

[traritonblitz]

Pls Help:I tried to do hole in object i opened in fusion but when i want to click on cut it say:NO TARGET BODY FOUND and i cant figure out how to cut into the object(but when i tried it on sam object as in video it worked normally)

[baurainfred]

It IS great i learn a lot with you ! I have a problem i try to cup a component witch IS a copy of an other one ant it cuts both how do i do ? Sorry if i don't speak so good english thanks for answer

[daanviegasdamas]

Great I have a question. On the first part where you have the hole. I need to open up the hole, so remove the mesh there. How can I do that?

[nigelford]

i have a specific case question maybe you can help; how do i make a 2d sketch on a surface made out of multiple circles with lines connecting the outer edges a single shape to extrude?

[Creator_Nater]

Fantastic tutorial, thank you! This is going to be very useful, I’d almost given up looking for a way to cut a gland/race for an o-ring. SUBSCRIBED!

[mikedavis]

Hi i'm new to CAD, your videos are good instruction. one thing i was trying to practice was how to use the sweep tool through the cylinder.
