Lesson video

Hi, everyone, I'm Mrs. Courts, and I'm very pleased join you for today's lesson on architectural orthographic projections.

This is part of the products and people, inspirational design units.

Our lesson outcome for today is I can create an architectural prototype model using computer aided design.

In our lesson today, we have three new keywords.

Let's have a little look.

Perspective view, perspective view.

A perspective view is viewing 3D objects in 2D, where objects look smaller as they get further away.

Orthographic view, orthographic view.

Orthographic view is viewing 3D objects in 2D to scale, showing each side of a design without perspective.

And finally, elevation, elevation.

Elevation are different views of an object.

In our lesson today of architectural orthographic projections, we have two parts, two learning cycles, and our first is about orthographic projections.

An orthographic projection is a type of drawing used by architects to show different views called elevations of a building.

Usually, there would be a plan or top elevation, a side elevation, which can be the left, right, or both, and a front elevation.

Jacob said, "Architects don't usually do a view from underneath," though.

Brilliant, Jacob.

Well done.

So orthographic projections can take a 3D object such as this building brick to show different elevations.

Plan or top elevation, the side elevation, and a front elevation.

We're now ready for our first check for understanding, so I hope you're listening really, really carefully.

So, which elevations do orthographic projections usually show? Left, right, back elevations, back, front, plan elevations, back, side, plan elevations, or front, side, plan elevations.

Pause the video now and have a little think.

Welcome back.

So, which elevations do orthographic projections usually show? Is the front, side, plan elevations, D.

Well done, everyone.

This is an orthographic plan or top view of a simple building brick.

Here is the plan elevation.

So looking directly down from the top.

It is often called a bird's eye view because you can view it from above.

This is an orthographic side, left or right view.

This is a side elevation.

Some designs might need left and right views if they are different.

And this is an orthographic front view.

This is the front elevation.

So this is often important to show what the front of the building will look like when we face it.

Orthographic projections are often drawn exactly in line with each other.

Here's the plan or top elevation.

Here's the front elevation, and here's the side elevation.

So therefore, we're now ready for our next check for understanding.

Hope you're listening ever so carefully.

Brilliant.

So which elevation is a front view of this building brick? A, B, or C.

Pause video now and have a little think.

Welcome back.

So which elevation's the front view of the building brick? That's right, it's B.

Well done.

We're now ready for our first task, task A.

And I'd like you to take an object from the classroom and talk about the elevations of it.

Talk about which is the plan elevation, which is the front elevation, and which is the side elevation.

Pause video now and join me when you're ready.

Welcome back.

Hope you had lots of fun finding an object and talking about the different elevations.

Did you find the plan elevation, the front elevation, and the side elevations? Super.

Well, Jacob and Sam chose to describe the front, side and plan elevations of a ruler.

"This is the plan view elevation of a ruler," said Jacob.

"The front and side elevations are very thin," said Sam.

We're now ready for our next part of our lesson, our second learning cycle, which is on Tinkercad orthographic projections.

So Jun's class have been asked to reorganize the head teacher's office using a computer aided design, CAD, applications such as Tinkercad.

Their teacher had already created a 3D version of the office for them to access through Tinkercad.

Jun said, "There are only walls, doors and windows in the design." We're now ready for our next check for understanding, so I hope you're listening really, really carefully.

So Tinkercad is what type of software? A, computer aided design, B, computer presentation device, C, computer drawing tool, or D, computer circuits design.

Pause video now and have a little think.

Welcome back.

So, Tinkercad is what type of software? You're right.

It's computer aided design, CAD.

Well done.

So Jun's head teacher needs the following, a desk, storage, and a group table.

Jun adds a desk, two cupboards, and a square table.

Jun says, "This looks good to me." So Jun's teacher then asks the class to draw the designs as an orthographic projection.

Jun firstly switches to orthographic view.

So when Jun switches to top view, he notices that there are some improvements to be made with alignment.

Can you see any? "I need to move the group table further back against the wall," said Jun.

Well done.

Did you spot that? Brilliant.

So Jun aligns the objects in the office.

"This looks much neater," he said.

So Jun then labels all the objects in the room using the notes tool.

Do you know which one is the notes tool? Have a little look, see if you're right.

Super.

We're now ready for our next check for understanding, so I hope you're watching really carefully.

Brilliant.

So which icon allows you to add notes to designs in Tinkercad? Is it A, B or C? Pause video now and have a little think.

Welcome back.

So which icon allows you to add notes to designs in Tinkercad? That's right, it's C.

Well done, everyone.

So Jun changes the color of the different objects in the office design.

Here's your orthographic top view, and here is the perspective home view.

So Jun can now show front, right and top views of his designs.

This is the orthographic top view or plan view, and this is the orthographic front view.

And finally, this is the orthographic right side view.

Well done, everyone.

So Jun took screenshots of each elevation and placed them into an orthographic projection within presentation software.

Here is the orthographic top or the plan view.

Here is the orthographic front view, and here is the orthographic right, side view.

We're ready for our next task now, task B of Tinkercad orthographic projections.

And I'd like you to firstly decide as a class which room to redesign and what needs to be placed in the room.

I'd like you to then, number two, create a 3D Tinkercad design of the room in perspective view, adding shapes and objects.

And number three, check alignment, color, and move objects about until you are happy.

Number four, I'd like to check each view using the ViewCube.

And number five, create an orthographic projection of each view in a presentation software file.

I would like you to pause video now and join me when you've completed task B.

Have fun.

welcome back.

Hope you've had lots of fun.

Brilliant.

Well, Jun presented his finished design to his head teacher.

Have a little look.

"I even added the perspective drawing too," he said.

That's brilliant work, Jun.

How did you all get on? Have you shared your work with others? Brilliant.

We've reached the end of our lesson for today on architectural orthographic projections, and I hope you've had lots of fun.

Let's have a look through our learning points and see if we've met them all.

Orthographic projections shows side, front and top views.

Brilliant.

Tinkercad shows orthographic projections.

Brilliant.

Tinkercad orthographic view can show designs to scale from the front, back, top, bottom and side views.

Excellent.

And Tinkercad can turn 3D designs into orthographic projections.

Brilliant.

Well, well done again.

You've worked very, very hard, and I'll see you soon.

Bye.
