Computer Aided Design (CAD) is a form of software automation that uses various computer-aided design tools that helps engineers, architects and other professionals in the design activity purposes. It is considered to be both software and special-purpose hardware. In product lifecycle management, the use of geometric tools plays a significant role. The CAD is available in various packages ranging from 2D vector based drafting systems to 3D parametric surface and solid design modelers.

CAD allows you to prepare fast and accurate drawings. Virtually anything can be constructed and built as a design model developed in the CAD system. The flexibility to alter the drawings is performed very easily with a minimal effort. It is also referred as Computer Aided Design and Drafting (CADD). It is sometimes translated as computer-assisted or computer-aided drafting. The tool provides you a better and the faster way of developing the drawings with better creativity.

CAD is used in major areas like applications that involve computer graphics, computer- aided manufacturing, solid modeling, solving by constraints, architectural purpose and VLSI design. Other fields that use the CAD are Architecture Engineering and Construction, Building Engineering (AEC), Mechanical CAD (MCAD), Electronic and Electrical (ECAD), manufacturing process planning, and digital circuit design.

CAD uses four basic phases that are used for designing and manufacturing. They are the requirement phase which collects the basic requirements and conceives the basic idea. The designing phase uses detailed component modeling and assembly modeling. The development phase uses engineering drawings. The tool design is used in the manufacturing phase.

Computer Aided Manufacturing (CAM), CAD/CAM applications, CAD scanners, CAD resources, and the software used by these computer-aided techniques all enable the drawing to be developed quickly and easily. General purpose CAD software, 3D rendering software, CAD/CAM software, facility management CAD, architectural CAD software, solid modeling CAD software and Mechanical CAD (MCAD) are the major computer-aided software applications that are used.

Most small companies and home users don’t need to buy an expensive solution for data backup. They can simply copy important files to a CD or DVD, and if an information loss occurs, they can get it back easily.
If it is simply to copy documents, photos and other files, not the same is for emails, attachments, address book, stationery and other related information from your Outlook Express email client.
This article will explain how everybody can create a manual Outlook Express backup copy (because Outlook Express don’t offer a built in backup function) This email program is usually installed with the Windows operating system and is probably among the most commonly used email programs today.

1. Backup email messages
In Outlook Express, emails are stored in files with DBX extension. The easiest way to find these files is to open Outlook Express and from menu select Tools | Options | Maintenance and click the Store Folder button. Here you can find the path to the folder containing your emails.
This procedure works for all kind of email: SMTP / POP3, IMAP, MAPI, or even the Hotmail Account (some messages might be stored only at the Hotmail server).
To save all your emails and attachments you should copy all the DBX files from the folder.

2. Account settings:
Details about your mail and news accounts are stored in the registry. To find them, start RegEdit and select the “HKEY_CURRENT_USER\Software\Microsoft\Internet Account Manager” key from the left panel. To save this data, from menu select: Registry | Export Registry File. Save the file to a name like "accounts.reg". 

3. Mail Rules
The Outlook Express mail rules are stored in the registry, in the “HKEY_CURRENT_USER\Identities” key. To save this data, from menu select: Registry | Export Registry File. Save the file to a name like "rules.reg". 

4. Address Book
The backup of address book is easy to do. It is stored in files with WBA extension. To find the location where address book is stored, you should open Outlook Express and from menu select File | Export | Address Book and select the comma separated text file as your output format. Click Export, select the folder where the backup will be saved and set the name for the backup file. After that click Next and choose the fields you want to include in your backup. Click Finish and your backup will be ready.

5. Stationery
The Outlook Express stationery location is stored in a registry key. To find it, you should open RegEdit, find “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Stationery” key and look at “Stationery Folder” value. There you will find the path to stationery folder. To save the stationery, you should copy all files from that folder.

If you think that manual backup is too hard, you can use a backup software tool, which can make the job much easier. Outlook Express Backup Expert is one product that can be used to easily create Outlook Express backups. It can save your emails, attachments, address book, signatures, blocked list, mail rules, stationery, accounts and settings. The biggest advantage to use automatic email backup software is the schedule function, which will create backups at specified time intervals, without user action. The downside of using a automatic email backup utility is that it costs money, usually about 20-30 USD as one time payment, while the manual backups are of course, free.
The conclusion is that email backup is a critical operation for every user.

How many application windows do you have open during your typical computer work? If it's just one, you may stop reading at this point. If, however, you do have a clutter of windows on your computer desktop - go no further, you've just found the solution!

Windows offers a convenient way to access applications and documents you use often by placing shortcuts to your computer desktop. These shortcuts are fast to click, but what if you have a window or two on top of your desktop? Minimizing or moving around an active window to access your desktop may seem a good solution for a while, but what if you work with more than just one or two applications? Those shortcut icons are covered well enough to make you spend a while to minimize or move away every window that blocks desktop access.

OK, maybe desktop shortcuts are not that great an idea after all. Let's open that same shortcut from the Windows Start menu! Click Start, select All Programs, and locate the application you were looking for. Slow, isn't it? I told you.

Wait, here's the Show Desktop button! Let's click it! Great, you can see the desktop and start your shortcut. Fast? Yeah! But hey, where are your windows? Those multiple applications you were using for work? They're minimized. Let's try the Desktop button once again... nope. It minimized the window you've just opened. It only worked until you actually started the shortcut. To restore your other windows, see the beginning of this article - minimize, minimize, minimize, and restore, restore, restore. Slow and boring.

DESKonTOP by http://www.shuric.com/deskontop.shtml finally solves the puzzle. To launch a shortcut from your desktop simply click DESKonTOP icon near the system clock, and you'll see a small copy of your desktop with all shortcuts and icons. You can easily launch a shortcut from there, and that's it! No need to minimize or move windows around. No need for Start menu exploration. No playing hide-and-seek with your windows. All it takes is one click on DESKonTOP icon, and one more click to launch a shortcut!

Once the mouse cursor is over an icon, DESKonTOP will enlarge it to show you the full-size version of the icon and its text label, allowing you to clearly see and click the shortcut without training your sniper skills.

Still find it difficult to use the small icons on the reduced copy of your desktop? No problem! DESKonTOP is readily customizable, allowing you to fine-tune the appearance of the mini-desktop the way you like it. Larger icons or text labels? Distinctive background? Small copy of your real desktop? All that and much more is possible with DESKonTOP. If you don't like a mini-desktop, consider switching to menu mode, and DESKonTOP will display all your desktop shortcuts as menu items.

If you have any personal information on your computer at all and access the Internet it is vitally important that you consider the benefits of a computer firewall. Many people lock their homes, lock their cars, keep a watchful eye on their children, and yet leave the bank accounts, personal information, and all kinds of other information vulnerable and exposed through their personal computers.

A virtual attack can be just as devastating financially and emotionally as someone breaking into your home. They are allowed access to secrets you may have shared in confidence with online friends or even offline friends that you correspond with online, they will have passwords for financial and banking accounts, they will know where you buy your coffee; they can learn where your children go to school. The information we have on our personal computers is staggering in terms of personal security nightmares and yet so many people take no steps to secure this information from prying eyes by investing in a simple computer firewall.

The amazing thing is that you can even find free computer firewalls available online if you know where to look. I highly recommend paying for a computer firewall though if you have little knowledge of the inner workings of your computer. If you’re going to secure your families secrets you may as well invest in a very good program with constant updates in order to do so.

A computer firewall isn’t just a nice thing to have on your computer; it is a vital line of defense for you and your family. Keep this in mind when choosing the best computer firewall for you. Remember you want to have a service that will provide updates and keep up with evolving technology that would harm your computer or steal your personal information.

Achieve the most from digital photography and enhance digital pictures with SnapTouch.

A digital camera is only as good as the pictures it takes. Experienced photographers spend hours touching-up images to achieve the best visual results and preparing the pictures for printing. Digital photographers make countless choices deciding which camera and settings to use to take a picture, and what software and which tools to use to enhance the picture afterwards. At each post-processing step, the tools you use to enhance the picture affect the image, enhancing or degrading the result.

Regardless of your choice of photographic software, one thing is certain. The computer and image editing software are an essential part of the digital workflow. Computer-edited digital pictures appear in newspapers and glossy magazines, billboards and advertisements. If you have just one image, spending an hour in Adobe Photoshop to get the perfect print makes sense. If you take hundreds of images, however, taking care to enhance each individual image consumes so much time and effort that many prefer to forget the whole idea. But what if you had a proper tool to make your digital workflow simple, quick and effective?

SnapTouch (www.snaptouch.com) takes care of the entire digital workflow quickly and efficiently. SnapTouch takes care of every step after you take a picture from helping you transfer pictures from the camera into the computer to preparing already enhanced images for printing.

Transferring images from a digital camera might be easy, but SnapTouch also makes it smart. It can automatically sort pictures depending on the day they were shot, naming and placing them into folders accordingly. Specify your own transfer scenario, and your digital pictures will be sorted, named and placed depending on your very own criteria.

Correcting and enhancing images is the second step of your digital workflow. During this step, you compensate and correct gamma and exposure, adjust brightness and contrast, rotate and flip pictures, remove red-eye and resize your pictures for Web viewing or printing. SnapTouch is designed to handle jobs to enhance bunches of multiple images while maintaining the highest quality through the entire workflow.

The third step of your digital workflow depends on what you're planning to do with the image. If you're up to making a Web album or archiving images on a disk, use SnapTouch to stamp your pictures by imprinting the date they were shot, naming the pictures or embedding your signature. You can specify your own font and color for the stamp, making your digital pictures appear as works of art.

If you're going to print a multitude of images, consider the different aspect ratios of your digital pictures and the paper they will be printed on. The two common aspect ratios are 4:3 and 3:2. Why gamble on what will be cut out of your photographs in the printing lab when you can specify your own crop in no time? SnapTouch allows you to specify the aspect ratio of the paper you're printing on, and processes your images with a moving fixed-aspect frame. By specifying the frame position you are making crops showing your main subject without cutting out important features.

SnapTouch is a digital photographer's workhorse allowing you to process batches of hundreds of digital pictures in a straightforward workflow. Combining advanced features and unique automation with unprecedented ease of use, SnapTouch is a must-have tool for advanced amateurs and digital photo professionals.
