Skills to be used in this project… Basic Skills New and Higher Skills Zoom tool Arc tool Orbit tool Follow Me tool Pan tool 3D Text tool Line tool Paint Bucket tool Rectangle tool Load a new toolbar Circle tool Eraser tool Push/Pull tool Basic skills are those required to do very basic drawings and are detailed as part of this presentation. New and higher skills may be new to the novice and are the focus for learning in this presentation.

1. Once you have opened SketchUp, go to Window and select Preferences. 2. Select Template and choose Metric Millimeters-3D. We are using this template because we are doing a product design. Therefore, on some versions of SketchUp you will need to select Product Design & Woodwork, Millimetres. Note: It is often necessary to start a new file to use the new template. Go to File then New.

3. Now select the Circle tool and draw a circle on the base, starting by clicking on the axis origin point for the circle centre. Look for the yellow dot that shows the origin point. 4. Using the mouse, move the cursor to enlarge the circle. DO NOT PRESS ENTER. First type ’15’ and then press Enter. This will give you a circle with a 15 mm radius which will be very small. Roll the middle wheel of the mouse to zoom in on the circle. The mouse is smart and will zoom into the area where you put the cursor.

Some useful tips… Note: If you make a mistake at any time during this tutorial you can just go to Edit and choose Undo from the drop-down menu, or press the Alt and Backspace keys. You can use the Orbit tool to change the angle that you are viewing your design from. You can do the same by pressing the middle wheel of your mouse. You can also use the Pan tool to grab and move your object around the screen. Alternatively, you can pan by pressing the Shift key and holding down the mouse's middle wheel.

5. Now you have zoomed in, you should see the circle like this. Now draw another circle a short way along the red axis. 6. If you move the mouse slowly to make the circle, SketchUp will try to predict the size you want and make it the same as the first one. Alternatively, just type ’15’ and press Enter again. Don’t worry if the circles overlap slightly.

7. Now select the Line tool from the toolbar. 8. Move the cursor to the point where the circle crosses the green axis. It should show a green dot as an endpoint. Click here to start the line. 9. Move the mouse along to the edge of the other circle where another endpoint will show up as a green dot. Click here to complete the line. At this point, SketchUp will shade in the newly formed shape. 10. Do the same on the bottom edges of the circles. All your lines should be tangents to the circles to create the best shape.

11. Now select the Eraser tool and click on the internal lines of the shape to rub them out. It should now look like this. 12. Now select the Push/Pull tool. 13. With the Push/Pull tool, click on the shape you have drawn and it will highlight it with a blue texture. Move the cursor upwards and it will pull the shape into a 3D form. DO NOT PRESS ENTER. Type ’25’ and press Enter to make the shape 25 mm high.

The next bit requires you to use your judgement for the sizes. 14. First, select the Rectangle tool. 2 15. To start the rectangle, select the endpoint (green dot) at the bottom of the shape, where there is a vertical line joining it (1). Move the mouse gently up the vertical line to find the top endpoint (2: do not click on it) and then pull away from the shape to make a rectangle that is about the size shown. Click to create a rectangle that sticks out of the main solid shape. 1 16. Now select the Arc tool from the toolbar. 3 5 17. To start the arc, click on the top right-hand corner of the rectangle (3). Click again where you want the arc to end (4). Now, by gently moving the cursor you can bend the middle of the arc to the shape you want (5) and click to finish it. 4

18. Use the Line tool to join the bottom left-hand corner of the rectangle to the arc. Note: Make sure the join is at a tangent to the arc. 19. Use the Eraser tool to delete the outside edges and any untidy internal lines that are not needed. It helps if you zoom right in using the middle mouse wheel so that you don’t miss any untidy bits. Your shape should now look like this.

20. For the next bit, you will need the Large Tool Set. If it is not shown on the left-hand side of your screen as a column of icons then you can get it from the main toolbar under View then Toolbars and then select Large Tool Set. 21. Now select the Follow Me tool.

22. With Follow Me selected, click on the new profile shape 22. With Follow Me selected, click on the new profile shape. It should then be highlighted blue. Then put the cursor on the top edge of the main solid shape. It should be highlighted in red as shown. Gently move the cursor all the way around the top edge of the solid shape until you get back to the starting point. Click to finish. You now have a solid shape with drafted sides, i.e. like a jelly mould. It should now look something like this, though there may be some differences due to the shape of profile that you have drawn.

23. Now use the Push/Pull tool to select the top of the solid and push it down a little before typing ‘2’ and pressing Enter. 24. Now you are going to put some lettering on top of the solid. First, select the 3D Text tool from the Large Tool Set on the left-hand side of your screen. 25. When the Place 3D Text box comes up, use the same settings as shown here (unless you wish to change them).

At this point, it may be worth orientating the object so that you judge the position of the letters properly. To do this, just push down the middle wheel of the mouse and move it. 26. Place the word where you want it to be and click to fix it in place. You can always move it again by using the Move tool from the top toolbar. If necessary, orientate the solid again. You can also use the Pan tool, on the top toolbar, to move its position on the screen. 27. To colour the solid, you now have to select the Paint Bucket tool.

Here is how the finished chocolate should look. 28. A window like this will pop up. Chose Colors and scroll down to find a suitable chocolate colour. I have used Color_B16. The cursor will turn into a paint bucket. Use this to fill every part of the chocolate, including the underneath. You will need to Orbit the solid to do this. A quick way to colour the whole object is to use the Select tool to put a box around the whole object and then fill it in one go. Here is how the finished chocolate should look. Extensions: Make a series of differently shaped chocolates as you would have in a selection box. Make different shapes or put different words and patterns on them. Use some different colours for white chocolate details, etc.
