Lesson video

Hello, I'm Josh, welcome back to 3D modelling.

In this lesson, we're going to look at creating our own 3D model on a photo frame.

This is the last lesson in our unit.

So we're going to use all of the skills that you've developed through lessons ones to five.

And we're going to use that design that you created in lesson five, so make sure you have that to hand.

You will also need a pencil and some paper, so make sure you've grabbed those now.

And you'll need your class login for the Tinkercad software.

So make sure you have your class code and your nickname ready to go.

If you've got those bits and you have a nice quiet space, free from any distractions, then let's crack on with creating our own 3D models.

So in today's lesson, you're going to develop and improve a digital 3D model.

So we're going to develop it first, and then we're going to look at how we can improve it, okay? In order to do these things, you're going to decide how it could be improved.

You're going to modify your model to make those improvements or improve it in some way.

And you're going to evaluate your model against a given criteria.

So those are the things we're going to be doing today.

But before we do any of that, what I'd like you to think about is this question.

What makes a good 3D model of a photo frame? What would make it a high quality model? Pause the video and consider that question, and resume the video when you've finished.

Welcome back then.

Hopefully you've had a bit of time to think about what would make a good quality 3D model.

So let's just go through a few bullet points together.

First thing is accurate dimensions, okay? You need to make sure that what you've created in Tinkercad is the exact dimensions that you would need it to be when you were to 3D print it.

That's a really important main point that we need to remember when we're making our models.

The next thing is that the 3D objects need to be correctly placed, and alongside that they need to be correctly grouped.

If we're printing it and it's not correctly placed, then we're going to have gaps in our model and it's not going to fit together correctly.

So unless you have a way of collecting those objects and pushing them together when they're printed, you need to make sure it is printing as one whole model.

It needs to fit a 152 millimetre by 102 millimetre photo.

That was one of the key criteria that we talked about in lesson five.

And finally, it needs to have a stand, okay? It needs to be able to stand up some way or another.

So those are what we will need to make sure that we've definitely got a good high quality photo frame created in Tinkercad.

So let's move on and start looking at how we're going to create our models.

So on the screen, you can see my design from the previous lesson.

This is my very basic design.

I've got my development stages of how I'm going to create my model.

Great, I've added notes, and I've added the dimensions that I need.

So I have a cube, says to resize the cube, okay? So resize a solid cube to those dimensions.

That's my first step.

So that's the first thing I'm going to do within Tinkercad.

So let's have a look at doing that now.

So the first thing I'm going to do that is just drag that box onto the work plane here.

And that needed to be 172 millimetres in its width.

So I'm going to drag that out to resize to 172 millimetres.

Just centre my box.

So I've resized my box, it's now 172 millimetres in width as shown on my diagram.

So now I need to go away and make it 122 millimetres in height, and 20 millimetres in depth.

So I'm going to jump back into Tinkercad software now just to finish resizing my box.

So I've got my box.

As you can see here, I'm just going to make that now height 122 millimetres and depth 20 millimetres.

Now, what could make the depth 122 millimetres and the height 20 millimetres? It doesn't matter which way around it is.

And it depends how you want to create your photo frame.

At some point you will have to rotate it in order to make sure you've got your stand in the right place.

And it stands as you'd expect it to stand.

But I'm going to make mine 122 millimetres tall.

So I'm just going to lift my cube here, zoom out so you can see.

And it should, I'm just going to check, but it should already be 20 millimetres in depth.

So that is step one of my development stages complete.

So my box now is 172 millimetres by 122 millimetres by 20 millimetres.

And that was my first development stage, So I've now completed my first development stage, I've resized my cube.

I can now move on to the next step and then continue through my development until I'd created my picture frame.

So, what I'd like you to do now is I'd like you to pause the video, and I'd like you to take the time to create your own photo frame using the design you created in lesson five.

So follow your design stages through, you might have to add extra bits in there.

You might have to add extra steps or extra items. It depends how you want to make your photo frame.

And it depends how detailed your previous design was.

But pause the video, create your photo frame now, and resume the video when you're finished.

Welcome back.

I hope you enjoyed creating your photo frame, and you've put a lot effort into creating it, making sure that it is meeting all of those requirements that we determined at the of this lesson, and what would make it a good high quality 3D photo frame.

We're just going to have a quick look at what mine looks like.

So you can see mine.

And if you wanted to go back and make some changes based on my design, feel free to do so.

Just make sure you've paused the video before you do that.

So here's my basic model of a photo frame.

And as I was going through my development stages, I noticed there was a few things that didn't work.

So there was a few issues that I had to amend and change as I was going through.

So it's not always about following it directly.

So I'm just going to rotate here so you can just see around.

So one of the issues I had is that I didn't have a back to my photo frame.

I had it all the way through a hole, all the way through, Now, that meant I couldn't put a back stand on it.

And it also means that my picture wouldn't have been able to sit in there and not fall out.

So what I did is I just made sure that my whole cube didn't go all the way through to give it a two millimetre back.

And then I realised that if I was to put a clear plastic front on my photo frame, I won't be able to put a photo in it.

So I have to add a little hole at the top here.

You can see I've got a two millimetre hole which goes through into this space, so I can insert a picture.

So I've got that.

That was an extra thing I had to add in there.

I did that by just adding another hole.

So if I ungroup my project all the way through, you'll be able to see I've got my main hole here which does not go all the way through.

And then I added another hole object at the top to create my space for my photograph to go into.

So that was couple of things I had to change there.

I'm just going to group it all again, just so it's easier to see.

Another thing I had to change is I changed the dimensions of my stand.

Now, my stand was a different dimension to this and I realised that whilst I was doing it, it was going to be too thick.

And it was also going to be too long.

So I had to make sure that I changed that so that it will fit in nicely behind my photo frame.

And in addition, I also rotated my photo frame before I connected my stand.

Now, the reason I did this is because if it was standing at a 90 degree angle, it's not very easy to see the photo in the photo frame.

So not only did I rotate my stand at the back, to the 30 degree angle that I had in my development stage, I also rotated my actual photo frame to 22.

5 degrees.

Now, if I was to print it, I would probably make sure it was standing up nice and neat.

Okay, just solely so that it was balanced when it was printing and it didn't fall over mid print.

So that's the last thing we'd want to happen, it would just ruin the print.

So this is my photo frame.

It's quite basic at the moment, but I'm hoping that it meets all of the requirements needed.

So I'm going to go ahead and look at our next steps now, as we look at evaluating what we've created.

So that was my basic model of a photo frame.

And in order to make sure that it meets all of the requirements that we discussed in the previous lesson, I now need to evaluate my model.

And I'm going to do that by using this table here, okay? Now on your worksheets, you have a criteria.

You will have a column that says met? Yes or no, and you need to make sure that you've noted down whether you've met that criteria.

And you'll need to make a few comments about how you know you've met that criteria, okay? So how do you know that your photo frame will fit a photo of 152 millimetres by 102 millimetres? Make a few notes about why you know that your project has met the criteria that we discussed previously.

So what I'd like you to do now is I'd like you to pause the video and complete task two on your worksheet.

If you're making notes instead of writing on the worksheet, you can make notes in that style of table.

So make sure you've got those headings as well.

So pause the video, complete the table, evaluating your 3D model, and resume the video when you're finished.

Okay, welcome back.

Hopefully then you have noted down whether or not you've met all of those criteria that we discussed previously.

And if you haven't met those, we are going to have the opportunity to improve our model based on our evaluation.

So let's have a look at what we're doing as the next step for this lesson.

So, improving our 3D model.

Now, as I just mentioned, if you are improving your model by making sure it meets the original criteria.

And great, that's something that we absolutely need.

So those original criteria are things that we might need to improve in our model if we've realised that actually, my model doesn't make use of that, or my model doesn't meet that requirement.

But there are other things that we can do to improve our models.

So as I was saying before, my model is very basic.

So what I might want to do is I might want to return and add an intricate design to my frame, a bit like the picture that's on the screen at the moment.

So it's got stars in the corners, it's got those lines throughout.

It just makes it look a little bit more appealing and a little bit less boring.

You might want to make it self standing.

So some photo frames don't have that back stand that holds it up.

Some of them stand by themselves.

Okay, so you might want to make it self stand and so you can have a look at ways of doing that within the Tinkercad software.

You also might want to add a wall mount.

Now, a lot of photo frames go on the wall.

So as you can see in the picture, on the back of this model, there is a very basic wall mount.

So the screw or the nail or whatever you've popped up on the wall slots into that bigger hole.

And the picture frame should push down on top of that now, and it should be held in place by the slightly smaller hole.

So, those are a few ways that you could improve your model.

Or as I mentioned, you could be going back to improve it by making sure it meets those original criteria.

So what I'd like you to do is I'd like you to pause the video and complete task three on your worksheet.

So there are suggested changes that you could make to improve your model.

You might also, like I said, go back and improve your model by making sure it meets the original criteria.

Or you might have a completely different idea about how you would like your model to look or be, so make those improvements as well.

So this is your chance to improve on that basic design that you've already created.

Pause the video, have a go at doing that now, and resume the video when you're done.

Welcome back.

Hopefully you've had some time there to tinker with your project, and improve it in some way or another.

You might've taken my suggested changes and added those, or you might have added your own suggestions.

That's absolutely fine.

So what we're going to do now is just to have a look at an improved photo frame, and just take note of those different changes that have been made.

So here is my photo frame, my new and improved photo frame.

You can see it's slightly different to the image on the screen.

What I've done is I've changed it from using that round roof shape here.

I've made it into a wedge shape.

The reason I've done that is because I've also got a warm out on the back.

And as it was originally, the warm out wouldn't have been able to sit against the wall because there was part of the stand it would have been pushing.

So now that means I can either hang it on the wall, or I can have it freestanding.

I've also added intricate designs onto my frame just to make it a little bit more interesting.

And as you can see, I've added my name to the frame base.

So I've used what I was looking at in terms of improving my model.

I've used those suggested changes, and I've made improvements.

And now I think it's a lot better than it was before.

You could also add another stand on the back.

If you didn't want this free-standing, you could have your original stand, one that folds in, some photo frames have that.

We'll hang it, but also, it could stand freely if you wanted it to stand freely.

So that's my design.

I hope you've enjoyed creating your own and making your own changes.

I absolutely recommend going back and tinkering with your designs once you've finished each lesson.

It can be a really fun way of improving your proficiency using this software.

But also, if you wanted to go and 3D print it, you then have a design that you can go and 3D print, which is always really exciting.

So my new and improved design, I think looked much better, and I'd be really excited to go ahead and 3D print that if I could, if I had that ability and that access to that machine.

Before we finish up, I just want to talk a bit more about applications of 3D model and just remind you of some of the ways that this 3D modelling software can be used.

So it can be used in films and animations, okay? It can be used in video games as well.

Architects and interior designers regularly make use of this software because it means they have to go and physically build a model, which is really important, saves a lot of time and money.

You've also then got your 3D printing as we were just mentioning.

So toys are made using this software.

Your replacement parts for certain things.

You can also make face visors, which I think has been used quite a lot recently, and also prosthesis.

So your artificial limbs, hands, arms, legs, all can be made using 3D printing.

And there's a lot of exciting applications happening within the world.

So make sure you go and check out some new stories about some of the ways that 3D modelling software is being used.

And some of the ways that 3D printing is being used alongside that.

So that concludes lesson six, and the final lesson in our unit on the 3D modelling.

I'd really like to see the models you've created.

So do consider sharing them with us here at Oak National Academy.

If you'd like to do that, ask your parent or carer to share it on Instagram, Facebook, or Twitter, tagging @OakNational and #LearnwithOak.

I hope you've enjoyed moving through the designs in that Tinkercad software.

It's a really great application.

So do go ahead and check out a little bit more if you'd like to.

And if you can, go and do some 3D printing, which is really, really fun.

And you'll be able to see your models in a tangible form.

Thanks for joining me, I hope to see you all again soon.
