Final design presentation methods

A final design presentation in design & technology is like showing off the finished plan for a new product. It is important because it lets everyone involved see the design, understand how it meets the design brief, and get a chance to give feedback before actually making the product. It is like a final check to make sure everything is correct and everyone is happy with the design before moving forward.

By using CAD to create a rendering of our final design we can also use AR to test the design in context.

KEY WORDS:

AR (Augmented reality) - Augmented Reality (AR) is a technology that superimposes digital information, such as images or data, onto the real-world environment, enhancing the user's perception and interaction with their surroundings.

Render - to add textures and materials that make shapes look more realistic.

Context - the surrounding conditions or circumstances that provide meaning and influence the interpretation of a particular event, idea, or statement.

Follow the steps below to create and AR model of your table. You will use Onshape, Shapr 3D and Procreate to complete this lesson task. You should then use the model and images created to make a Final Design poster using Procreate.

Chamfer the table edge

There are two different methods to chamfer your table edge. The method you need to use depends on the pattern of your table.

Method 1 (Chamfer Tool)

This works with your table top if your pattern has all straight edges around the perimeter of the table.

Method 2 (Sweep Tool)

This will work with all patterns, but has to be used for any table tops that have triangular patterns with the corner of a triangle on the perimeter of your table.

Chamfer feature method

As you can see, it has chamfered the edge where the lines are parallel with the perimeter. However, where there is a corner of a triangular shape, it cannot chamfer it.

Sweep feature method

As you can see, the triangle shape is swept along the perimeter of the table top and removes all the material from all the parts.

chamfer feature tool

Select the chamfer tool on the features menu

Click to select the edges of the table on all sides

The yellow highlights the selected edges.

Sweep feature tool

To complete the chamfer using the Sweep Feature, you are going to have to:

use the sweep tool
create a profile to sweep
create a path to sweep the profile along
remove the material

Follow the steps below to do this.

1 selecting the face for the triangle profile

Click on the vertical face of the side of your table.
Click on Sketch.
Rename the Sketch as 'Profile of Chamfer'

2 drawing the triangle profile in the right corner

Use the line tool to draw a triangle in the top right corner.
Don't worry about the size as you draw it.
Click on the 'Dimension' tool or press 'D' on the keyboard.
Make the top and right lines 10mm

3 Selecting the face for the path Sketch

Click on the top face of the table.
Create a new sketch on this face.
Rename the Sketch as 'Path of Chamfer'.

4 Drawing the path on the path sketch

Click on the rectangle tool.
Draw a rectangle from one corner to the diagonally opposite one so that you have a rectangle like the red rectangle above.
Click the green tick.

5 using the sweep tool to sweep the profile along the path

Click on the sweep tool.
Make sure the settings are as shown in the image.
Click the green tick.

Table assembly - Adding the table Legs

TABLE ASSEMBLY

Click the link above to access the table assembly and copy the workspace

Copy the workspace and name it appropriatly

Select insert > Other documents > Owned by me

Select your table in the list

Click on the workspace to place the table then press the green tick

On the left of the screen, select the parts of the table by holding the shift key on the keyboard and select all the listed parts from the 6th part down to the bottom of the list.

Use the axis arrows to move the table around and position it on top of the base.

Exporting the table from Onshape

Once the table model is assembled, move the mouse to the bottom of the screen to the assembly tab. Right mouse click and select the Export option from the menu.

Change the file name. Change the format to STEP. Press export.

The file will now export to the downloads folder.

This will take a few seconds - be patient!

Open finder and the downloads folder.find the STEP file, click share and airdrop it to a school ipad.

NOTE: you will need to turn on airdrop on the ipad.

Importing to shapr 3D

Open the Shapr 3D app on a school ipad. It needs to be the one you airdropped the STEP file Open the import menu from the top right menuand then click files.

Select recent and the air-dropped file should be at the top pf the list.

Once the table model opens, click Modeling in the top left corner.

Now select Visualization.

you are now in a mode where you can render your table model with suitable materials.

Drag the materials onto the model to change the material

Repeat for all of the pattern shapes of your table.

Change the material menu to metal

Now drag a metal material onto the legs - "Cast Iron" looks good.

Select AR to start an AR image. You can play with the Material / Environment / Camera settings to get different effects

When in AR mode, point the camera of the Ipad to place the table in the image.
You can move the table around with your fingers and change the angle too. Press the white dot to take a screen capture image.

Carefully choose the context for the image to show your table. It would be best if your context matches the one you identified earlier in the project. You can also get images in a white environment by pressing object at the top of the screen.

Now make a Procreate poster

Use the AR images you have created to make a final design poster.
