1. S2 INVENTOR GAME BOY part one MAIN BODY

2. S2 INVENTOR Here is what the finished result might look like once put together...

3. S2 INVENTOR We are now going to start a new file which we will use to create the body of the Game Boy. 3 – Click on ‘Standard.ipt’ 2 – Click on the ‘Metric’ tab 1 – Click on ‘New’ 4 – Click‘OK’

4. S2 INVENTOR We are now going to draw a 2D sketch which very roughly represents the outline shape of a Game Boy. 1 – Click on the Line tool Now we can think about making the Game Boy the right sizes. 2 – Create the basic outline shape on the sketch area, do not worry about size or position at this stage

5. S2 INVENTOR Now would be a good time to dimension the Game Boy. It is easily done with the ‘General Dimension’ tool. 1 – This is the ‘General Dimension’ tool 2 – Click and drag on the each line of the Game Boy. Change the sizes as indicated With the Game Boy fully dimensioned, we should now look at it in Isometric. 80mm 100mm 60mm 120mm

6. S2 INVENTOR With the Game Boy fully dimensioned, we should change our view to Isometric in order to see the effects of the extrusion better. 1 – Right Click and the following menu will appear 2 – Select ‘Isometric View’ We are now going to add a third dimension to the flat Game Boy.

7. S2 INVENTOR For now, that is all of the sketching we need to do so we are going to leave the sketching environment and start 3D modelling. 1 – Click on the ‘Return’ button Now that we are in the modelling environment, notice that the range of tools available has changed.

8. S2 INVENTOR We can quickly and easily turn the 2D Sketch into a 3D model by extruding it. 1 – Click on the ‘Extrude’ tool and the following dialog box will appear 2 – Set the extrusion height to 30 and you will see a shadow of the new model appear 3 – Click OK We can now begin to add detail to the plain block

9. S2 INVENTOR The next step is to take away many of the sharp corners on the model. We will do this by a process called filleting. 1 – From the menu, select ‘Fillet’. The following dialog box appears … 2 – Select 4mm as the radius 3 – Next, click on ‘Edges’ and then select all of the top surface edges and all of the bottom surface edges. 4 – OK this The block now has a much softer feel. We are ready to apply a material to it.

10. S2 INVENTOR The last step is to apply an appropriate material and/or colour to the model. 1 – Open up this drop down menu 2 – Select ‘Red’ The body is now complete. We can save the file and start a new part.

11. S2 INVENTOR We should now save the model we have made with an appropriate name and in an appropriate location. 1 – Click and select ‘Save’ 2 – Save it into your own folder. Call it ‘Game Boy - Body’ Now we can close the file

12. S2 INVENTOR GAME BOY part two THE SCREEN

13. S2 INVENTOR We are now going to start a new file which we will use to create the screen of the Game Boy. 3 – Click on ‘Standard.ipt’ 2 – Click on the ‘Metric’ tab 1 – Click on ‘New’ 4 – Click‘OK’

14. S2 INVENTOR We are going to start creating the screen by drawing a two dimensional rectangle. We will now move from sketching to modelling 1 – Select the ‘Two Point Rectangle’ tool and drag a rectangle onto your screen 2 – Use the General Dimension’ tool to make the rectangle 60 wide x 50 high 60mm 50mm

15. S2 INVENTOR We will go from the sketching to the modelling environment here. 1 – Click on ‘Return’ 2 – Right click and the following dialog box will appear … 3 – Select ‘Isometric View’ This Isometric View is ready for extrusion

16. S2 INVENTOR The next stage is to extrude the sketch into a 3D model. 1 – Click on the ‘Extrude’ tool 3 – OK this 2 – The following dialog box appears – set the extrusion height to 3mm The edges of the screen should now be chamfered

17. S2 INVENTOR The extruded screen now needs the sharp edges to be angled slightly – a process known as chamfering. 1 – Click on the ‘Chamfer’ tool 2 – The following dialog box appears 3 – Set the distance at 2mm and select all four edges With the screen chamfered, we will now apply the material

18. S2 INVENTOR We will now apply a suitable colour/material to the screen for added realism. 1 – Go to the materials drop down menu Save it into your folder and call it ‘Game boy - Screen’, then close the file

19. S2 INVENTOR GAME BOY part three BIG BUTTON

20. S2 INVENTOR We are now going to start a new file which we will use to create the button in the shape of a cross 3 – Click on ‘Standard.ipt’ 2 – Click on the ‘Metric’ tab 1 – Click on ‘New’ We can now start to sketch the button. 4 – Click‘OK’

21. S2 INVENTOR We are going to start creating the button by drawing a two dimensional shape which is roughly correct. We will now make the cross the right size. 1 – Select the ‘Line’ tool 2 – Draw something close to the ‘cross’ shape shown. At this stage do not worry about sizes but do make sure all lines are either horizontal or vertical – watch the on- screen symbols which will indicate when lines are equal length and at right angles

22. S2 INVENTOR We are going to make the button the right size by, firstly, making all lines equal then, secondly, making one of them 10mm. 1 – Click on this drop down menu to reveal a range of constraints 2 – Select ‘Equal’ 3 – Now go round and click on all of the lines to make them of equal length We will now make the cross into a 3D model 4 – Use the ‘General Dimension’ tool to make any one of the lines 10mm

23. S2 INVENTOR We will go from the sketching to the modelling environment here. 1 – Click on ‘Return’ 2 – Right click and the following dialog box will appear … 3 – Select ‘Isometric View’ This Isometric View is ready for extrusion

24. S2 INVENTOR We will now extrude the button to give it a thickness of 4mm. 1 – Click on the ‘Extrude’ tool 2 – This dialog box will appear 3 – Extrude to a value of 4mm and OK this We can now add a bit of realism by filleting the edges

25. S2 INVENTOR In reality, this button would have rounded edges to make it feel better. This process of rounding off sharp edges is known as filleting. 1 – Click on the ‘Fillet’ tool 2 – This dialog box will appear 3 – Click on all the top edges 4 – When all top edges have been selected and the radius is set at 2mm – OK this 5 – Go into the materials drop down menu and pick a colour for the button Your button is now created. Save it in your folder and call it ‘Game boy - Large Button’

26. S2 INVENTOR GAME BOY part four SMALL BUTTON

27. S2 INVENTOR We are now going to start a new file which we will use to create the small round button of the Game Boy. 3 – Click on ‘Standard.ipt’ 2 – Click on the ‘Metric’ tab 1 – Click on ‘New’ We can now start to sketch the small round button. 4 – Click‘OK’

28. S2 INVENTOR We can now dimension it 1 – Use the ‘Line’ tool to create this rough shape We are going to start creating the small button by drawing a two dimensional shape which is roughly correct.

29. S2 INVENTOR Using the General Dimension tool we will dimension the shape. TIP – dimension the small sizes first, largest size last. We can now ‘Revolve’ it 1 – Dimension the shape as follows …

30. S2 INVENTOR We are going to revolve the 2D shape now with the usual first step of moving from an orthographic to an isometric view. 1 – Right mouse click and select ‘Isometric View’. 2 – Click on ‘Return’ to move into the modelling mode Let’s take this shape and revolve it

31. S2 INVENTOR We will become familiar with the features of the ‘Revolve’ dialog box in this step. 1 – Click on the ‘Revolve’ tool 2 – The shape will be highlighted and the following dialog box will appear 3 – Click on this button to define the axis around which the shape will rotate 4 – Select this line to be the axis 5 – You should get a preview of the rotation. If you are happy with it, OK it. This is stage one of the small button complete

32. S2 INVENTOR The sharp corners are now going to be removed by applying a large 5mm fillet on two edges. 1 – Click on the ‘Fillet’ tool, the following dialog box will appear … 2 – Set the fillet at 5mm and select the two edges shown here highlighted in blue 3 – The result should look like this 4 – Pick a suitable material The small button is now complete.
