Tutor Guidance and
Autodesk Inventor Configuration
These notes have been written in such a way to illustrate best practice methods, and as such Autodesk Inventor needs to be configured to help reflect these methods.
It is recommended therefore, that Tutor's ensure that their CAD workstations are configured in the following manner to assist the CAD Parametric Modelling user in following this courseware for the City & Guilds 4353-21 CAD Parametric Modelling module.
Course File Management
For the purpose of these notes, all course files are referred to as being in the 2010 4353-21 folder (directory) under Student. It is
recommended therefore, that these folders be created and all course files are placed therein. The courseware files can be installed to any local or network, but the files and folders must have read/write status set. Therefore, a system of replacing the courseware files periodically would be advisable.
Autodesk Inventor Installation
In order that the coursware performs correctly, it is necessary for the ISO standard to be chosen when Autodesk Inventor is installed and not the default ANSI standard.
This is necessary so that new files created by Autodesk Inventor are in metric (mm) units, instead of the default imperial (inches) units.
Graphics Card
It is recommended that the latest Autodesk approved Graphics Card Driver for Inventor is installed, for optimum performance and to prevent system crashes.
A link to approved Graphics Card Drivers can be found on the installation disk and on the Help menu within Autodesk Inventor.

Introduction
WELCOME
to the 4353 CAD Parametric Modelling Scheme using Autodesk Inventor.City & Guilds 4353 CAD Parametric Modelling Scheme
These training notes have been designed to introduce the user to ICT, Windows Operating System, and the basic Autodesk Inventor modelling and editing commands, to provide a broad level of understanding required to appreciate the essential concepts and principles of using Autodesk Inventor in Windows XP/Vista.
The notes have been arranged in such a manner to develop the ICT and CAD Parametric Modelling skills necessary to take you step by step, through the exercises and assignments, and reflect the actual areas of expertise that are required for the City & Guilds 4353-21 Computer Aided Design Parametric Modelling - Level 1 Award.
It is not the purpose of these notes to explore every facet of ICT and Autodesk Inventor, but merely to prepare you for the City & Guilds practical assignments and on-line multi-choice question test. You will, no doubt, further explore the commands used and others, at some future time.
Whilst some experience of 3D parametric modelling would be an advantage, knowledge of the application software is not considered a prerequisite to undertaking this course.

Use Associated IT, CAD Hardware and
Operating Systems
Information Technology
Information Technology (IT) is made up of the transfer, processing and storage of information (eg graphics, vectors, text, sound, numbers, etc.) using computers, telecommunication net-works and other electronic devices.
One of the largest areas in IT is the use of computers. They enable you to process information and perform specific tasks much more quickly than you could do yourself.
CAD Parametric Modelling Hardware
Personal Computer (PC)
The computer most used in the home and work environment is known as the Personal
Computer and is the backbone of any CAD workstation. It is a device that manipulates data
according to a set of instructions.
Hardware
Peripheral Devices
The computer may have any number of other components attached to it collectively referred to as Peripheral Devices. These also come under the hardware category and may consist of:
Floppy Disk Drive Hard Disk Drive CD-ROM Drive
Zip Drive DVD Drive USB Flash (Memory) Drive
Keyboard Mouse VDU (Monitor)
Modem Scanner Speakers
Digitiser Graphics Card Printer/Plotter
A combination of the above can usually be found on a CAD workstation
Input and Output Devices
Of these peripheral devices, some are termed Input devices and others Output devices. Some examples are:
Input Devices Output Devices
Mouse VDU (Monitor)
Keyboard Scanner
Digitiser Speakers
Trackball Printer/Plotter
Central Processing Unit
The Central Processing Unit (CPU) is the main microprocessor and together with the motherboard, graphics card and memory make up the basic essentials of a personal computer. The CPU is regarded as the brain of a personal computer system and performs calculations on inputted data and determines what to do with the results of those calculations. The CPU’s activities are co-ordinated by a clock which is used to synchronise all the internal processes within it. The unit of time for each movement of data is called a cycle and the clock speed is measured in Megahertz (MHz). One megahertz equals one million cycles per second. Obviously, the faster the CPU, the faster the data is processed, and hence, the computer runs much more quickly.
Motherboard
The Motherboard is a key component of the computer, as all other devices are connected to it and it serves as the link between them. It is the data and power infrastructure for the entire computer.
Graphics Card
The Graphics Card (sometimes called the video card/processing card) interprets the data generated by the computer and displays it on the Visual Display Unit (VDU),often called a Monitor.
A modern graphics card is made up of a circuit board with memory and its own dedicated processor. The processor is designed specifically to handle the intense computational requirements of displaying graphics.
Figure 02 Keyboard and Mouse
Figure 04 Monitors
Types of Memory
The information stored on a computer is kept in its memory. The two main types of memory are
Temporary (RAM) and Permanent (ROM) memory.
Any data in the computer’s temporary memory will be lost when the computer is switched off, while the data in the computer’s permanent memory is retained.
Random Access Memory (RAM)
RAM is a computer’s main memory store and can be written to and read from. It acts as temporary storage for any programs that are running and the data they are using. It also stores the data being transferred to and from the various parts of the computer, but all data will be lost when the computer is shut down.
Read Only Memory (ROM)
Programs and data stored in a computers ROM cannot be changed during normal operations and are retained when the computer is shut down.
Visual Display Unit (VDU)
The Visual Display Unit (or Monitor) has a screen that presents the visual information about the computer’s activity and is the most-used device on a personal computer.
Screen sizes are normally measured in inches from corner to corner diagonally. Popular screen sizes in use for CAD are 19", 21" and upwards.
The Cathode-Ray Tube (CRT) monitor screen is made up of a series of dots, called pixels, and the greater the number of pixels on display, the greater is the resolution (ie better definition). CAD users should aim for a minimum resolution of 1024 x 768 pixels, whilst those using the larger screens often have them set as high as 1600 x 1200. The higher the screen resolution, the more you can fit on the screen, but each item on the screen will look smaller. The disadvantage of CRT monitors are in their size, weight and the screen is bowed,
sometimes distorting lines at the edge of the screen.
More common type of monitors in use, based on newer technology, are the Liquid Crystal

Storage Devices
Hard Disk
Hard disks consist of a number of rigid magnetic disks in a protective casing. Data is recorded magnetically onto concentric circular tracks, each of which is divided into a number of sectors. Hard disks can hold very large amounts of data, measured in gigabytes (GB) and terabytes (TB), and are very fast in comparison to other storage devices.
Floppy Disk
Floppy disks are flexible magnetic disks held in a protective plastic jacket 3½" in size. As with hard disks, data is recorded onto concentric circular tracks, divided into sectors.
Floppy disks can hold only small amounts of data (typically 1.44MB) and are relatively slow in operation. Rarely used nowadays.
Zip Disk
The Zip disk tends to cover the middle ground between the hard disk and floppy disk, in terms of both speed and capacity. There are currently three data sizes available, being 100MB, 250MB and 750MB, but their use is being rapidly overtaken by the USB Flash Drive.
USB Flash Drive (Memory Stick)
The USB flash drive is a small portable flash memory card that plugs into a computer's USB port and functions as a portable hard drive with storage capacities in excess of 4GB. Sometimes called pen drives, stick drives, memory sticks or USB drives and are rapidly replacing the floppy disk and zip disk as preferred portable storage media.
CD-ROM
A CD-ROM is a Compact Disk (CD) with Read Only Memory (ROM) often used to supply program data such as software. However, it can be used to
store large amounts of data (typically around 700MB), but cannot be written to again once closed or full.
CD-ROM’s are created using a CD-R disk (R meaning Read only) and the data cannot be erased or overwritten, but another compact disk in use is the CD-RW (RW meaning rewritable which can be re-formatted and re-used, although relatively slow when writing (burning) to the disk
Types of Software
Operating System
A computer’s operating system controls the running programs, along with the storing and processing of data. It also presents a default
interface to the user, which is loaded automatically when the computer is started.
The Microsoft Windows XP and Vista operating systems produce such an interface. These Graphical User Interfaces (GUI's) provides images (called icons) that represent applications and other available software. A GUI is usually driven by pull-down menus and toolbars which are accessed using a mouse.
Application Software
Application software are packages such as AutoCAD, Autodesk Inventor Professional, Microsoft Office, Adobe Acrobat, etc. The majority of computer programs are application packages, but cannot run without an operating system to act as a link between them and the computer.
Computer Performance
The operational performance of a personal computer system depends on the time taken for the hardware and software to interact and manipulate the necessary data.
In terms of CAD, a personal computer’s performance can be greatly enhanced by ensuring that:
•
a CPU with a high clock speed is used•
a large amount of RAM is installed (4 GB or more)•
a high performance Graphics Card is usedPrinters and Plotters
The most common types of printer in use are the inkjet, bubble-jet and laser.
Inkjet and Bubble-jet printers form shapes and characters from a series of dots, by firing tiny
droplets of ink at the paper from a print-head that moves horizontally across the paper. The ink is supplied in cartridges, including colour, and the paper can be single sheets up to ISO A0 in size or fed from a continuous roll.
They are quiet, reasonably fast and produce very good quality prints.
Laser printers combine a very narrow beam of light and a light sensitive drum to fuse particles
of toner onto the paper. The toner is a very fine powder, and is also used in photocopiers. They produce very high quality prints, including colour, usually up to ISO A3 in size. In the ISO A4 size they are extensively used in the business office.
Plotters, up to ISO A0 in size, work by drawing lines on paper using different coloured pens
held in a mechanically rotating head. This technology in the field of CAD, has gradually been

The Internet
The term Internet is used to describe the global network of all networks that currently spans in excess of 250 countries.
The World Wide Web is the fastest growing service on the Internet (not to be confused with the Internet itself). It describes the vast collection of hypertext-based files available on the Internet and provides a quick and easy way to retrieve these files so they can be viewed and/or downloaded using a browser.
Search engines are used to find information on the Internet, such as CAD web sites where
related information and CAD files can be downloaded.
Electronic mail (e-mail) is an electronic postal system through which all kinds of data can be
sent and received, and is the most popular activity on the Internet. Messages and CAD drawing files can be sent much more quickly than by conventional means.

A Good Working Environment
Under the Health and Safety (Display Screen Equipment) Regulations 1992 as amended by the Health and Safety (Miscellaneous Amendments) Regulations 2002, the employer and computer user have joint responsibility to make sure all workstations are safe and comfortable to use.
Ergonomics is the study of factors affecting the performance of people at work. When working with computer equipment, it is well established that a bad working environment can cause certain health problems.
Bad working practices (sitting in a fixed position at the keyboard for long periods, making awkward movements with your arms, head or body) can contribute to a variety of ailments ranging from eyestrain to pain and discomforture in the limbs.
These are easily preventable by taking time to ensure that your adjustable chair, desk and monitor are positioned correctly. Figure 01 below shows how you can optimise your sitting position in relation to your desk, PC, keyboard, monitor, etc.
Zone 1 - Eyes
Ensure you sit at a comfortable viewing distance (38cm - 81cm) and angle that doesn't strain your neck. Glare or reflections should be minimised by tilting and swivelling the monitor as necessary. The top line of the VDU should be just below your eye level.
The brightness and contrast of the VDU should be adjusted so that it is easy to read, and there should be no flicker or instability in the image.
Zone 2 - Head, Neck and Shoulders
Avoid awkward neck movements.
Sustain proper body posture - arrange your workstation to fit your body and needs. Allow enough room to move around.
Zone 3 - Forearms, Wrists and Hands
Avoid bending your hands at the wrists when typing. Wrists should remain at a similar height to the key board or mouse. Use of a wrist pad and mouse pad may help.
Forearms should be parallel to the floor.
Zone 4 - Back
Adjust your seat height for correct posture, sitting well back to take advantage of any lumbar
Zone 5 - Legs and Feet
Adjust your chair to the correct seat height - thighs parallel to the floor, feet flat, knees level with your hips. Also ensure adequate space from the back of knees to the seat - they should be slightly higher than the chair seat. A footrest may be of help for some users.
General
Take frequent breaks to get up and move about to help invigorate your muscles, relax your eyes and stimulate blood flow.
The keyboard and monitor should be cleaned regularly, and adequate lighting and ventilation should be in place.
Ergonomic equipment works with your body's natural movements, thereby avoiding awkward movements and physiological stress.
Eyestrain and Headaches
Looking at a monitor for long periods of time without a break can make your eyes tired and cause headaches.
•
Using a large good quality monitor that produces a clear image on the screen may help reduce this problem. The rate at which the monitor renews (refreshes) this image is also important. Higher image refresh rates are often more comfortable than lower ones, because they reduce visible flicker on the screen.•
Adequate lighting should be provided. If the ambient lighting level is too low, you will experience increased glare from the monitor screen. If it is too high, you will experience glare from the lighting itself. Also, no light should be reflected from the screen.•
Filters that reduce glare from the screen are available. However, these are not a substitute for adequate lighting.Repetitive Strain Injury (RSI)
RSI is a complaint that occurs when the same task is carried out repeatedly for a long period of time, making use of the same muscles continuously.
•
RSI has been linked with the use of the mouse/trackball and keyboard.•
Ergonomically designed, angled keyboards are now available to reduce the risk of strain injury through typing.Back Pain
Sitting at a CAD workstation in a bad posture can cause lower back pain. This is especially true if you sit for long periods of time without getting up.
To help prevent back pain, monitors and workstations should be positioned at the correct height for the user and adjustable chairs that provide support to the user's lower back should be used.
Ventilation
Adequate ventilation is also important when using computer equipment. Computers and monitors give off a lot of heat and make the surrounding air very dry. This can cause your eyes and throat to become dray and uncomfortable if there is an insufficient supply of fresh air. Also, some printers give off toxic fumes, so good ventilation is essential if these are kept in the same room where you are working.
Health and Safety Guidelines
The Environmental Health Department of your Local Authority is responsible for the enforcement of health and safety legislation, and the Health and Safety Executive (HSE) is responsible for developing health and safety standards throughout the UK (website -www.hse.gov.uk).
Some Important Points...
•
When spending a long time at a CAD workstation, look after your health by taking regular breaks of at least 10 minutes per hour, spent walking around rather that stretching at the desk.•
You should adjust your chair and monitor to find the most comfortable working position.•
Using a mouse/trackball or a keyboard has been linked to Repetitive Strain Injury (RSI). Therefore, take regular breaks from using them.•
When sitting down for long periods, you should make sure that your back is well supported in order to avoid damaging it. Avoid sitting in the same position for long periods, adjust your posture as often as is practicable.•
Avoid repeatedly having to stretch to reach things you need. If this continually happens, rearrange your workspace.•
If your workspace is limited, place any readable material on the side of your dominant eye.•
Keep your workstation in a clean, cool and dust free environment.•
Make sure your power points are not overloaded. Overloaded power points are a potential fire risk.•
Make sure that all cables are secured safely at the back of your workstation where they cannot be tripped over or pulled out of your computer by accident.•
Know where the fire extinguishers are located and the emergency evacuation route out of the building in the event of a fire.Switching Off Your Computer
Switching off your computer without shutting it down properly may damage any files or data that are still in use. To switch off your computer correctly:
•
Save any files (in particular drawings) you are working on. If you switch off your computer without saving these files, you will lose any changes you have made since the last time you saved them.•
Exit from any application (in particular AutoCAD) software you are using.•
Shut down your Operating System in the recommended manner.Computer Crashes
Despite the best efforts of programmers, software will sometimes go wrong and stop the computer working. Often when this happens, the computer locks up. That is, it does not respond to any input or commands.
To help regain control of your computer, you can try simultaneously pressing the
[Ctrl] + [Alt] + [Delete] keys on your keyboard. This may cause your computer to do one of
the following:
•
Display a warning screen describing the fault, and explaining the options you have to continue and what may happen as a result.•
Windows XP: Display the "Windows Task Manager" dialog box listing all theprograms that are running and which of them are not responding. You may be able to use this dialog box to exit from the program(s) causing the problem and so regain control of your computer - you will lose any unsaved data from those programs.
•
Windows Vista: Display a menu from which "Start Task Manager" may beselected.
If above doesn't enable you to regain use of your computer again, you will have to reset or switch off your computer.
Resetting the Computer
Resetting your computer will force it to perform a warm (or soft) boot, ie exit from the Operating System and re-read its startup instructions.
To reset your computer, press its reset button, usually located on the front of the computer and may be labelled Reset.
Switching Off the Computer
If you choose the option of switching off your computer and then back on again, it is known as a cold boot.
Firstly press the power button to switch off the computer, then wait until the computer has completely powered down and the hard disk has stopped spinning (you should be able to hear this happen), and then wait about 15 seconds before switching the computer back on again.
Note: When you restart your computer following a crash, the Operating System may perform a system check as it loads.
It may run a program called ScanDisk or CheckDisk, which examines the files and folders on your hard disk for any errors and hopefully repairs them. The system check will usually run automatically.
Power Cuts
If there is a power cut, it has the same effect as turning off your computer without shutting down the Operating System - you will lose any unsaved data.
•
When power comes back on and you restart your computer, the Operating System may perform a system check as it loads.•
To help prevent data loss, an Uninterruptible Power Supply (UPS) can be used, which is a battery powered device attached to your computer that protects against power cuts. If there is a power cut, the UPS continues to supply power to the computer so that you can shut it down properly without losing any data or causing any damage to the hard disk.Preventing Data Loss
The following guidelines will help in preventing the loss of data:
Set up your CAD Workstation in a Safe Environment
Your computer should be located in a dry, cool, controlled environment that is clean and dust-free.
Placing your computer in a low-traffic area will also protect your system and storage media from harmful jarring or bumping.
Backup your Data Regularly
Creating regular backups is one of the most effective ways to protect yourself from losing data. Back up data on the hard disk at least once a week (daily if necessay) with reliable tapes or other large storage devices, and always verify that the correct data has been backed up. Smaller amounts of data may be backed up or archived to such devices as floppy disks, zip disks or CD-ROM's, with the former two being write protected as an added precaution.
Use an Uninterruptible Power Supply (UPS)
In the event of an electricity surge or lightning strike, an Uninterruptible Power Supply will protect your computer from being fried. If UPS is not an available or economical solution, a power surge protector is a good investment.
Use Anti-Virus Software
Computer viruses are one of the worst enemies to your computer. Good anti-virus software (updated regularly) tests your system for sequences of code unique to each known computer virus and notifies you of any infecting invader, allowing you to then eliminate it.
Be Aware of Strange noises
If you hear a strange noise or a grinding sound, turn off your computer immediately and call in an expert. Further operation may damage your hard drive beyond repair.
Software Copyright
Most software is copyrighted, which means that the right to make copies lies only with its originator (or those who have been given permission to copy). The same law applies to a number of different products, such as pre-recorded videotapes, music CD's and certain reading material. It is illegal to copy, share or lend copyrighted material.
•
As with videotapes and CD's, copying software is contrary to The Copyright, Designs and Patents Act 1988 which protects the work of playwrights and artists, but also covers software.•
A company may have hundreds of employees who need the same software on their computers. Software manufacturers do not expect such companies to buy indi vidual copies of the software for each employee. Instead, they will issue a licence, which means that the company can install the software on an agreed number of computers for their employees to use. For example, Microsoft Office and Autodesk software products.•
If the site has a large number of computers, these computers are often networked. This means that software bought under licence can be installed onto a network server so that all authorised users can access it without it being installed on each individual computer.Shareware and Freeware
While most software is copyrighted, there are some exceptions:
•
Shareware - This is software you can install free of charge so that you can evaluateit for a limited period of time. If you decide to continue using the software after this period, you should register it for a fee. When you register the software, you often become entitled to extra features and support.
•
Freeware - This is software that is available completely free of charge, withoutThe Data Protection Act
The Data Protection Act 1984 regulates how personal data is collected, stored and used.
Confidentiality (ie the right to keep sensitive and personal information private) is now the right of each individual. You now have some control over how information about you is used, and can prevent data being passed between companies for marketing purposes, eg mass mailings. The main points of the Data Protection Act are as follows:
•
Any organisation holding personal data in a computer system must register with a Data Protection Registrar whose job it is to see that the Act is enforced.•
When they register, companies must specify the purposes for which they intend to use the data. Data must then be fairly and lawfully obtained (ie not under false pretences), and must only be used for a purpose that has been registered.•
An individual has the right to know whether any information is held about him orher, and to request to see that information. For example, if an individual is refused credit, they are entitled to be told the name of the credit checking agency who must then, in turn, tell them what information is held about them.
•
If any information held about an individual is wrong, it must be changed or deleted.•
Data must not be given to anyone that is not entitled to it. It must be protected against unauthorised access, deletion, alteration or disclosure.Exemptions
There are exemptions from the Act, including:
•
Data not held on a computer. The Act only applies to computerised records.•
Medical records and records associated with crime ot taxation You are not entitled to see your medical records without the permission of your doctor, the police do not have to disclose any personal data held for the detection or prevention of crime, and the tax authorities do not have to disclose their tax records.•
Data associated with National Security. Any information deemed to be a risk to National Security can be withheld.•
Records held for internal company business (such as calculating wages), and records held for personal, family or recreational purposes. These records do not have to be registered.Units of Computer Memory Measurement
Bits and Bytes
The smallest component of computer data is a bit. Each bit can be in one of two states: 1 or
0 with the 1 standing for On and the 0 standing for Off. Bits are combined in sets of eight to
form characters, such as letters from the alphabet. For example, 01000001 is used to represent the letter A in binary code. This group of eight bits make up a byte.
Kilobytes
•
A kilobyte (KB) is often used to measure the download speed in seconds, on the Internet (KB/s) and the size of files.•
A kilobyte is 1,024 bytes.Megabytes
•
A megabyte (MB) is often used to measure the storage capacity of a disk or the amount of main memory. For example, a floppy disk can only store 1.44MB of data.•
A megabyte is 1,048,576 bytes (1,024 x 1,024 bytes or 1,024 kilobytes).Gigabytes
•
A gigabyte (GB) is equivalent to 1,024MB. The memory capacity of many large storage devices, such as hard drives, is measured in gigabytes.Terabytes
•
A terabyte (TB) is equivalent to 1,024GB.Files
•
A file is a collection of information stored as a single unit. When they have been saved, any of the following may be regarded as a file:- A computer program. - An Autodesk Inventor part. - Word-processed text. - A spreadsheet. - A computer graphic.
File Sizes
The size of a file depends on the amount of data it contains and hence, the amount of storage space required. For example, Autodesk Inventor data files can vary from small (say 100KB) to over 5MB in size for very large drawings.
Folder (Directory) Sizes
When you have a number of related files stored on your computer, you may want to store them in a folder. You can think of a folder as being like a drawer in a filing cabinet.
•
An empty folder does not contain any data (obviously). However, as a folder usually contains a number of files, the combined size of these files may mean the folder contains several thousand kilobytes (or several magabytes) of data.•
If you have a great many folders, each containing a number of files, the total amount of space required to store (and back up) all the data may run into several thousand megabytes (or several gigabytes). It is therefore easy to see how space on storage devices, such as hards disks, can be quickly be used up.•
Old and unused files (but still needed), should be archived to an external storage device to free up much needed hard disk space. Compression software may be used to reduce the file size and zipped for future retrieval.Autodesk Inventor Folder Structure
Your hard disk(s) should be organised into a series of folders and sub-folders for ease of use.
Autodesk Inventor, when installed, automatically
creates its own structure similar to that shown in Figure 02, and is usually installed on the C: drive under Program Files.
Note: The Student/2010 4353-21 folders are not automatically
created, but will need to be added (if not already created) and is where all the course files you will be using, are located.
Tutor to advise if Autodesk Inventor and/or the course files have been installed elsewhere.
Windows Explorer (Microsoft Windows XP)
Windows Explorer can be used to undertake 'housekeeping' routines on the
hard disk(s), and floppy or zip disks. For example, creating new folders (directories), and moving, copying, or deleting files.
Note: If you are using the Windows Vista operating system, ignore the following
and turn to Section 02-30.
Accessing Windows Explorer
Accessing Windows Explorer can be by one of two methods:
•
Method 1 - Right-click on the Start button andfrom the pop-up menu, click on Explore.
•
Method 2 - Left-click on the Start button anddepending on which Windows Desktop style you are using, a pop-up window will be displayed similar to Figure 02 or Figure 03 below.

Exercise - File Management
In order not to disturb the file structure on the hard disk, this exercise will be carried out in the
2010 4353-21 folder under Student (where the course files are located). Tutors Note: Tutor to ensure there are two
folders with sub-folders and their relevant files, under the
2010 4353-21 folder in preparation
for this exercise - see the section on
Tutor Guidance and Autodesk Inventor Configuration.
Creating Folders (Directories)
