Hi there, everyone, my name is Mr. Booth and welcome to your design and technology lesson for today.

It is wonderful that you could join me.

Today's lesson is about Fusion fundamentals.

We are going to start using the computer-aided design application, Fusion.

This lesson is part of the Systems approach to design: Sustainable futures unit.

Today's outcome, I want you to be able to transition from using Tinkercad to Fusion.

In Fusion, I want you to be able to navigate the Fusion interface and evaluate different types of 3D CAD modeling, such as Fusion and Tinkercad.

Three keywords for you today.

The first one is constructive solid geometry.

This is how Tinkercad functions, creating 3D models by combining simple shapes like cubes, or as Tinkercad slightly confusingly calls them, boxes, cylinders, and spheres.

We then have parametric solid modeling.

This is how Fusion functions, creating 3D models as full, solid objects that have volume, mass and can be tested or 3D printed using editable parameters.

And then, of course, we have parameters, measurements and rules used when parametric modeling.

We have two learning cycles today.

The first is all about transitioning from Tinkercad to Fusion.

So let's have a look.

Fusion is a cloud-based computer-aided design manufacture and engineering tool that is used both in design and technology classrooms, but also it's used widely in industry.

It is free to all educators and pupils.

Tinkercad is a free, web-based educational computer-aided design tool and this allows users to create 3D models quite quickly and easily for 3D printing.

It also allows you to build electrical circuits and also design with code blocks.

Fusion uses parametric solid modeling, creating 3D models using solid objects, and they're full solid objects as well.

They've got volume and they've got mass and they also have editable parameters.

Tinkercad on the other hand, is slightly more simple.

It uses constructive solid geometry.

Now this is where you create 3D models by combining simple shapes such as cubes, cylinders, and spheres.

Quick check for understanding.

What form of modeling does Fusion use? Is it A: parametric, B: CSG, C: 2D, or D: simulated? Pause the video now have a go at this and come back to me when you've got your answer.

It is, of course, parametric.

Solid parametric modeling.

Now Tinkercad will limit users as their designs become more complex.

As you get better at using computer-aided design and you also get better at designing products, Tinkercad will limit you in what you can actually design.

Fusion will give you more control over modeling.

It's the perfect application to transition to as your CAD knowledge and skills progress.

So let's have a little look at the comparison between the two.

So here we have the applications, Tinkercad and Fusion.

We have some strengths and also some challenges that you might find when using those.

So let's start with Tinkercad.

Well first of all, it's simple to use for beginners.

It's very user-friendly, it's web-based, so you don't have to download any complex software.

And of course we know it uses CSG modeling, which is great for simple models.

But there are some challenges to this.

You can't do complex simulations.

There is limited complexity.

There's no timeline or history to your modeling either, so you can't go back and edit things quite as easily as you can if you are using Fusion.

Let's a look at Fusion.

So it's a powerful cloud-based application.

You can use freeform, parametric and also sheet metal modeling options.

It has editable parameters so you can edit models very quickly.

There is full simulation and analysis and also integrated CAD to CAM within the actual application.

So if you get really good at Fusion, you don't even have to post process for 3D printing.

You can do it all within, through Fusion itself.

But there are also some challenges.

It's complex to learn and to use.

I'm only gonna teach you a small part of Fusion.

It's used in industry so you hopefully one day, you'll be really good at it.

It uses higher computer specification.

You need to have that in order to be able to use the software and the application correctly.

Quick check for understanding.

What is one strength of Fusion over Tinkercad? A: simple to use for beginners, B: CSG modeling, C: complex to learn and use, or D: integrated CAD to CAM? Pause the video now, have a go at this, come back to me when you've got your answer.

It is, of course, integrated CAD to CAM.

Well done.

Now Tinkercad is perfect for quick and easy modeling for beginners.

Fusion can be used for more precision, complexity and also if you need to analyze or simulate your model in some way.

So here we have a Tinkercad house model that might be done in a primary school.

And then, of course, here we have a slightly more complex model, which might be done by people doing their GCSEs.

And you can see the difference in the complexities between the two.

So the context in this unit, as we know, is sustainable futures.

Izzy wrote a design brief for the context.

So let's remind ourselves about that design brief.

"I'm going to design and make a control system to manage a greenhouse.

The control system will monitor and maintain the optimal conditions for the plants to grow and thrive." And we've highlighted those key points in there.

Now, Izzy wants to create a scale model for her greenhouse to test this system that she has been working on.

She'd like to create a complex 3D printable model, photorealistic renders to show what it will look like and also a technical drawing to assist with manufacture.

Now to do this, she simply can't use Tinkercad.

She's going to have to transition to Fusion.

To create the greenhouse prototype, we can, of course, use 3D printed components to hold the crops and the system and all those components that we have been using.

The greenhouse structure, the bit that goes around the plants, which, in your normal situation would be made of glass, can be created using a recycled fruit punnet.

Now what do I mean by that? Well, this is what you often get your grapes in when you do your weekly shop.

Now most punnets are standard sizes, but dimensions can vary.

So it's really important that you check the sizes of your recycled punnet before you continue.

But the great thing is we are gonna be using Fusion.

So the model I'm going to give you to edit, you can edit it very quickly to suit your punnet.

So this is the model, this is the greenhouse model and it can be downloaded and edited.

Now we are gonna use this model so you can become familiar with the features of Fusion and also test your system nice and easy.

Now one thing you do need to know is that your model may vary slightly from the images in this, because, of course, we have iterated it based on feedback.

And that's part of product design.

We're now onto your first task.

The first thing I want you to do is explain what is meant by CSG and parametric solid modeling.

I then want you to discuss why a user might use parametric solid modeling over CSG.

I'd then like you to download the greenhouse Fusion model and also log into Fusion.

Pause the video now, have a go at these tasks and come back to me when you've completed them.

So how did you get on? Let's have a look at some sample answers.

So first of all, I wanted you to explain what is meant by CSG and parametric solid modeling.

Tinkercad uses constructive solid geometry modeling, creating 3D models by combining simple shapes like cubes, which, of course, are boxes in Tinkercad, cylinders and also spheres.

Fusion uses parametric solid modeling, creating 3D models as full, solid objects that have volume and mass, using editable parameters.

I then wanted you to discuss why a user might use parametric solid modeling over CSG.

A user might want to use parametric modeling options as their models might be complex.

Parametric modeling will make editing models easier through the use of the timeline.

And finally, I wanted you to download the greenhouse Fusion model and also log into Fusion.

Now this is where you might need your teacher's assistance.

They will give you access to Fusion through the Fusion classroom.

You can log into Fusion yourself.

If you are of a certain age, you'll have to check the Autodesk Education website for that.

You can also download the Fusion model that I want you to use, the greenhouse model from the Oak website.

You just need to search "Fusion fundamentals" and find the lesson that you are in right now.

So now onto your second learning cycle, Fusion fundamentals.

Let's go.

Parametric solid modeling is used to ensure your design has what we call a timeline.

Design changes are captured and updated throughout the model to ensure the correct form and fit.

So here we have our greenhouse model and down at the bottom there, that is what we call our timeline.

And you can see there's lots of little symbols all there and they all mean something different.

Users can choose from modeling methods in Fusion, such as free form, parametric, which is what we are gonna do, and also sheet metal.

Now free form's an interesting one because if you need to make a really ergonomic design, it can be fantastic for that.

It's great for artistic design, manipulating faces, edges, and vertices to achieve your desired geometry.

Now we are gonna use parametric, and this can be used for solid objects that have volume, mass and can be tested or 3D printed, using editable parameters using what we've just looked at, which is, of course, the timeline.

Quick check for understanding.

What is this Fusion feature called? Is it A: the timestamp, B: the timeline, or C: the calendar? Pause the video now, have a go at this and come back to me when you've completed it.

It is, of course, the timeline.

So it's really important that you can navigate the user interface.

And in order to do that, you need to know what everything is called.

So first of all, we have what is known as the data panel.

And just like it sounds, it contains all your data, all your designs, that's where you'll find those.

We have the application bar at the top, and this is very similar to any other application bar that you'll get in other apps.

It has save on there, you've got undo and you've also got file on there as well.

We have what is known as the toolbar and you will see this will change, depending on which workspace you are working in.

We have the browser.

Now this contains all the components, the bodies, the sketches, and even the geometry for all your designs.

We have the canvas, this is where you produce your designs.

The view cube, which you might, of course, recognize from Tinkercad.

We have what's known as the marking menu.

If you right click your mouse on the canvas, you'll get all sorts of other options in there, including recently used features.

We also have the navigation bar.

The navigation bar does exactly what it says.

It helps you navigate around your canvas.

And then finally, you already knew this one.

We have the timeline.

Now the data panel is where you will find all your projects.

It's where your designs are managed and all your data is kept.

We also have the application bar.

Now this is where you can access the data panel by clicking on those nine squares.

You can also save, have you open your files, and also create new designs from the application bar.

Now a really useful starting tip from the application bar is to just to click on the little button in the top right hand corner and access quick setup.

If you click on quick setup, you can see which units you are working in, make sure they are set to millimeters.

But what you can also see is the mouse controls.

To find out what your mouse will actually do when you are working in Fusion.

So that's a really good place to start when you open up Fusion.

So we're now gonna upload the greenhouse model into your data panel.

So the first thing we need to do is create a new project.

So you need to open the data panel and then create new project.

I called it "Sustainable Futures" 'cause that's a sensible name, because that's the unit we're working in.

Then double click on that project to open it up.

We then have an upload button.

So we're gonna click on that.

And then what we're gonna do is navigate to where we have downloaded the greenhouse model.

You then need to select that where it says select files, make sure the location is correct, it should be going into your Sustainable Futures folder.

And then just click upload.

Now, through the toolbar, users can access workspaces, such as design, render and drawings.

And if we look at that there, you can see we have all those different workspaces that we can work in.

Now what we are gonna do is we're actually gonna only use design, render and drawing.

But you can see there's lots of other options there that can be used in Fusion.

Now photorealistic renders are really easy to produce in Fusion.

You can use physical materials and appearances and also set scenes up to make them look really realistic.

And here you've got some fantastic examples of products that have been rendered.

You can also simulate with Fusion.

So if you wanted, for example, to do a static stress test or heat up your product to see how it performs under different temperatures, you can do that directly within the Fusion workspaces.

Quick check for understanding.

Identify the Fusion workspaces.

We have A: design, B: model, C simulate, and D: sketch.

Which are Fusion workspaces? Pause the video now, have a go at this and come back to me when you've completed it.

So the Fusion workspaces are, of course, design and simulate.

Yes, we can model and sketch in Fusion, but they are not workspaces.

Assemblies can also be created and simulated and these will show movement and also check if parts will fit together.

They will be slightly more complicated than the Tinkercad simulations that you might have completed.

And you can also create technical drawings.

Here we have an orthographic drawing with an isometric view on there.

And this will, of course, help with manufacturing of your prototypes.

You can also access tools for additive manufacturing using 3D printing directly through Fusion, which means you don't actually have to use external post-processes.

Most of us still use external post-processes and we are going to use external post-processes for our model.

But actually in Fusion, you can do it all directly through there as well, when you get really good at the application.

Quick check for understanding.

True or false? Once a model has been designed in Fusion, it can't be edited.

Is that true or is that false? Pause the video now, have a think about that and come back to me when you've got your answer.

Well, that is, of course, false, but why? I want you to try and explain why.

So once again, pause the video, come back to me when you've got your answer.

It is, of course, because we're using parametric modeling and that's used for solid objects.

They have volume, mass and can be tested and 3D printed, but more importantly, they are editable using the parameters which you set when modeling.

So we're now onto Task B.

First of all, I would like you to describe three advantages of using Fusion over Tinkercad.

Then with Fusion open, navigate around the user interface identifying all nine areas.

I then want you to open the quick setup and set your units to millimeters.

I want you to open the data panel and create a new project called Sustainable Futures and upload the greenhouse model into that folder.

I then want you to open the greenhouse model so you can view it in Fusion in the canvas, then use pan, zoom and orbit to navigate around the model.

You can even check the timeline and have a look at that.

Check the quick setup for mouse controls if you're not sure.

Pause the video now have a go at this task and come back to me when you've completed it.

So how did you get on? Well, let's have a look at some sample answers and see if you managed to complete all the other tasks.

So first of all, I wanted you to describe three advantages of using Fusion over Tinkercad.

Well, first of all, photo-realistic renders are easy to produce using physical materials and scenes.

Models can be simulated in far more complex ways than Tinkercad, utilizing analysis tools and to assess their suitability.

Users can also access tools for additive manufacturing using 3D printers, directly through Fusion.

I then wanted you to open Fusion and navigate around the user interface and hopefully you found all those nine different areas that we looked at earlier in the learning cycle.

I wanted you to open the quick setup and set the unit, so hopefully you did that.

And then open the data panel, create a new project called Sustainable Futures and upload the greenhouse model.

And finally, I wanted, with the greenhouse model open, you to use pan, zoom and orbit to navigate around the model.

You might have needed to check the quick setup for your mouse controls.

Hopefully you've done all that.

Absolutely brilliant.

Well done.

So that brings us to the end of today's lesson.

Let's have a quick summary to see what you have learned.

First of all, Tinkercad and Fusion are cloud-based CAD applications.

Tinkercad is based on CSG, which makes it easy to use and accessible, especially for beginners.

Fusion is a sketch-based application, based on parametric solid modeling, giving users more control to create complex models.

And finally, Fusion allows users to create complex assemblies, photorealistic renders, and also technical drawings to assist with manufacturing.

You've been absolutely wonderful today.

I hope you've enjoyed the lesson.

I'll see you next time.

Goodbye.
