How to use this user guideThis handbook accompanies the taught sessions for the course. Each section contains a brief overview of a topic for your reference and then one or more exercises.

Exercises are arranged as follows:

• A title and brief overview of the tasks to be carried out;

• A numbered set of tasks, together with a brief description of each;

• A numbered set of detailed steps that will achieve each task.

Some exercises, particularly those within the same section, assume that you have completed earlier exercises. Your teacher will direct you to the location of files that are needed for the exercises. If you have any problems with the text or the exercises, please ask the teacher or one of the demonstrators for help.

This book includes plenty of exercise activities – more than can usually be completed during the hands-on sessions of the course. You should select some to try during the course, while the teacher and demonstrator(s) are around to guide you. Later, you may attend follow-up sessions at ITLP called Computer8, where you can continue work on the exercises, with some support from IT teachers. Other exercises are for you to try on your own, as a reminder or an extension of the work done during the course.

Text conventionsA number of conventions are used to help you to be clear about what you need to do in each step of a task.

• In general, the word press indicates you need to press a key on the keyboard. Click, choose or select refer to using the mouse and clicking on items on the screen. If you have more than one mouse button, click usually refers to the left button unless stated otherwise.

• Names of keys on the keyboard, for example the Enter (or Return) key are shown like this ENTER.

• Multiple key names linked by a + (for example, CTRL+Z) indicate that the first key should be held down while the remaining keys are pressed; all keys can then be released together.

• Words and commands typed in by the user are shown like this.

• Labels and titles on the screen are shown like this.

• Drop-down menu options are indicated by the name of the options separated by an angle bracket, for example File>Print. In this example you need to select the option Print from the File menu. To do this, click with the mouse button on the File menu name; move the cursor to Print; when Print is highlighted, click the mouse button again.

• A button to be clicked will look like this

• The names of software packages are identified like this, and the names of files to be used like this.

Steps

Continue working with your existing project. Alternatively open Advanced Techniques - Part 05.skp

Task

Create the path circle

Steps

Use the Iso view and Parallel Projection

Use the Circle tool

Create a circle with a radius of about 400 mm. This first circle is the path circle

Task

Create the profile circle

Steps

Use the Circle tool

This second circle has to have 3 properties:

• It must share the same centre as the first circle. Inferences will help with this

• It must be perpendicular to the first circle. Use Shift to lock on to an axis

• It must be smaller than the first circle

Create the second circle with a radius of about 200 mm. This second circle is the profile circle

Task

Create the sphere using the Follow Me tool

Steps

Use the Select tool

Select the first (path) circle

Use the Follow Me tool

Click on the second (profile) circle with the Follow Me tool

The second circle will be spun (lathed) around the first circle to create a sphere

Task

Turn the sphere into a component

Steps

Turn the sphere into a component and name it Sphere 01

Task

Move the sphere onto the table

Steps

Use the Move tool to move the sphere onto the table

You will find inferences and changing views will help you achieve this

Optional task

Create a vase

You will need to use a mixture of the Line and Arc tools to create a profile

Remember that the path circle will need to be larger than the profile shape and they must share a common centre point, see diagram below:

Remember to turn your finished vase into a component

Then place it on the table alongside the sphere

Task

Save your project

Steps

Choose File>Save

Notes

The edge of the profile (what will become the middle of the resulting lathed object) must line up with the middle of the path circle below

Steps (continued)

Create a diagonal guide using the following steps (see diagram below, numbers in diagram correspond to numbers in list below):

1. Position the Protractor tool over the top left corner of the wall (the inference will help you)

2. Click and move the Protractor tool to the to right corner of the wall

3. Click and move up, you will see a diagonal line following your cursor

4. Type 20 and press Enter to set the diagonal guide at 20 °

Task

Create a diagonal guide going the opposite way

Steps

Repeat the process to create a diagonal guide going the opposite way

The two guides should intersect above the middle of the wall
