What Is Design Analysis

Sat, 31 Jul 2010 11:00:41 +0000

The design analysis routines available in a CAD system help to consolidate the design process into a more logical work pattern. Rather than having a Thomas Sabo back-and-forth exchange between design and analysis groups, the same person can perform the analysis while remaining at a CAD workstation. This helps to improve the concentration of designers, since they are interacting with their designs in a real-time sense. Because of this analysis, capability designs can be created which are closer to optimum. There is a time saving to be derived from the computerized analysis routines, both in designer time and in elapsed time. These saving results from the rapid response of the design analysis and from the time no longer lost while the design finds its way from the designer's drawing board to the design analyst's queue and back again.
An example of the success of this is drawn from the experience of the General Electric Company with the T700 engine. In designing a jet engine, weight is an important design consideration. During the design of the engine, weights of each component for each design alternative must be determined. This had in the past been done manually by dividing each part into simple geometrical shapes to conveniently compute the volumes and weights. Through the use of CAD and its mass properties analysis function, the mass properties were obtained in 25% of the time formerly taken.
Since alterations in preliminary designs are generally easier to make and analyze with a CAD graphics system, more design alternatives can be explored and compared in the available development time. Consequently, it is reasonable to believe that a better design will result from the computer-aided design procedure.
Interactive CAD systems provide an Thomas Sabo Charms intrinsic capability for avoiding design, drafting and documentation errors. Data entry, transposition, and extension errors that occur quite naturally during manual data compilation for preparation of a bill of materials are virtually eliminated. One key reason for such accuracy is simply that no manual handling of information is required once the initial drawing has been developed. Errors are further avoided because interactive CAD systems perform time-consuming repetitive duties such as multiple symbol placement, and sorts by area and by like item, at high speeds with consistent and accurate results. Still more errors can be avoided because a CAD system, with its interactive capabilities, can be programmed to question input that may be erroneous. For example, the system might question a tolerance of 0. 0001 mm. It is likely that the user specified too many zeros. The success of this checking would depend on the ability of the CAD system designers to determine what input is likely to be incorrect and hence, what to question.
There is also a high level of dimensional control, far beyond the levels of accuracy attainable manually. Mathematical accuracy is often to 14 significant decimal places. The accuracy delivered by interactive CAD systems in three-dimensional curved space designs is so far beyond that provided by manual calculation methods that there is no real comparison.
Computer-based accuracy pays off in many ways. Parts are labeled by the same recognizable nomenclature and number throughout all drawings. In some CAD systems, a change entered on a single item can appear throughout the entire documentation package, effecting the change on all drawings which utilize that part. The accuracy also shows up in the form of more accurate material and cost estimates and tighter procurement scheduling. These items are especially important in such cases as ling-lead-time material purchases.
The single data base and operating system is common to all works-stations in the CAD system. Consequently, the system provides a natural standard for design/drafting procedures. With interactive computer-aided design, drawings are "standardized" as they are drawn; there is no confusion as to proper procedures because the entire format is "built into" the system program.

There Are Many Great Time-saving Diy Tips

Sat, 31 Jul 2010 11:00:41 +0000

A do-it-yourself or DIY renovation has many advantages: You can save money, save the headache of working with a contractor and bring your family and friends closer. Here is some great advice to help you get started.

While the thought of improving your home may seem daunting, there are a lot of small projects most people should be able to do. Almost anyone can fix holes in the wall or replace drywall. Even if you think you don't know how to do these tasks, one visit to a home improvement store will show you that advice is available.

The best thing to do is to plan out a job carefully before you start. Go online and read the various home improvement magazines for tips on how to get things done. Assemble all the materials you need and read all instructions carefully. It's a good idea to mime the actions in the instructions to make sure you understand them. Miming also shows you if you've forgotten any important materials or steps.

Visit a home improvement store before you begin. The store's personnel will be able to give you some handy tips. For example, they can show you how to handle a putty knife so inside corners come out nice and smooth.

The store's staff will also be able to point out other parts of the job that need to be done. For example, when you install a door, you also need to seal it against the elements.

Don't be afraid to call in family or friends for help. In fact, by working with others you can have a lot of fun and build bonds that will last a lifetime. You can always laugh about the time you painted yourself into a corner - literally.

If you decide you don't have the time or the skill to complete a project, it is best to hire a contractor. In fact, for some projects, a contractor is essential. Some state and local laws require licensed professional plumbers or electricians to be at least on site when specific jobs are being done.

For major work, it just makes good sense to hire a professional. The professional contractor knows all the safety considerations and other tips to do the job efficiently and safely.

When you hire a contractor, be sure to check his or her license and all references he or she may provide. Call your local Better Business Bureau to make sure there are no complaints logged against him or her. Sadly, the few contractors who are less than honest make the whole process harder for the rest of us. Once you found the contractor you wish to hire, read all contract documents carefully, especially the price, payment schedule and work schedule. Don't sign anything unless you understand it all. You don't want to get into a legal battle over a home improvement project.

Don't hesitate: get started today on improving your home. You'll be glad you did.

Professional Printing Quality For Technical Drawing

Fri, 30 Jul 2010 09:58:15 +0000

If you're a professional working with CAD and CAD related information and needing hard copy, you'll appreciate the need for top quality printing capabilities. Print quality equates to extreme accuracy in the print, as well as your specifications and patiently accumulated graphics. These are working documents, and they have to be good, as well as look good. Semi-legible plans aren't an option. CAD printing has to be done as well as the plans themselves.
CAD can help, but so can your printer

Fortunately, CAD is an almost self-explanatory drawing mode. You know the whole story of every line on the plan, line sizes, areas of text, etc. It's also helpful by nature because of its strongly regulated lines and coordinates, which is a very good printer-friendly setup by nature. A basic print dialog box will do most of the work, but with technical drawing you can add some failsafes and quality controls before you print.

The Draft and Text modes are particularly useful, because they use a minimum of ink. If there are any actual print problems, you'll see them on this type of print. If there are head or nozzle issues, the print will have gaps in lines, or blurry looking elements. Use the Advanced and Maintenance settings to clear up these issues.

Ink quality issues and getting the right setup

The dpi ratio is often the key to good line quality. Good quality printer inks, particularly those used for photo printing, are the best. You may find that photo quality technical drawings are more precise on your printer, because of the high quality ink applications to media.

If you're finding lines are looking variable, you can use imaging software to control dpi levels. Use a systematic increase or decrease in dpi to get the right settings. You don't need to waste ink, either, just do basic print maintenance tests with the new settings. Solid lines on tests mean you're ready to print.

A3 prints- quality before printing

Anyone who's ever wrestled with an A3 technical print knows the story. They're big, they're complicated, and there always seems to be something. They're also ink gluttons, if you let them get away with it.

The way to deal with these ink-hogging, line-sabotaging pests is with simple trickery. An A3 can be reduced down to an A5 easily. Simply test and do your quality controls on the A5. (A4 may use up a bit of ink, but you can try that for high detail, too.) You still have the level of detail, you can see problems, and you have some ink left.

Double checks using software for quality control

Another good quality control option is element printing. That's easy with CAD, and it's quick. You can do elements of the design as test prints. In some technical drawing printing jobs you may need element prints anyway, so you can do both at the same time. It saves ink, and will find any printing issues instantly

Buying A Carpet Steam Cleaning Equipment

Fri, 30 Jul 2010 09:58:15 +0000

Having a carpet in your house can be a bit of a night mare. A rather dirty night mare, which can be sorted out with normal vacuuming which generally brings up all the hidden allergens living in your carpet. To keep you family free of allergens, as your infants crawl on the carpets and breathe deeply of tie fumes and toxic dust that lurks in your carpets.

Shopping for the best non chemical based carpet steam cleaning equipment is as easy as pie. Infomercials advertise a variety of brands of carpet steam cleaning equipment for hours and general opinion is that it is not the brand that really matters it is what is in the carpets that you might want to get rid of.

Old Carpet Vs New Carpets

One may argue that carpet steam cleaning equipment are excellent, whether it be the portable carpet cleaning equipment or not, it is vital to know that the age of the carpet is what really matters. Old carpets have more bad things in them than you want to imagine. We are looking here all the host of allergens, bacteria, faecal contamination, dust mites, the works.

These can be easily cleaned out with you average water based carpet steam cleaning equipment preferably the ones that produces hot steam. Notwithstanding the fact that older carpets are more hazardous than the new ones as they contain banned chemicals. Imagine toxic filled dirt right under you feet! That would be the work of an industrial carpet steam cleaning equipment.

New carpets on the other hand are the ones that are more dangerous that the old ones. As good as the smell of new carpet is; it is the volatile organic compounds that are more dangers to your family than anything. These include chemicals such as benzene, ethyl benzene, acetone and a host of other dangerous chemicals which have been known to even produce foetal abnormalities in animals and case hallucinations and nerve damage in humans.

Now combine that with steam from the carpet steam cleaning equipment. That is a recipe for disaster for your family. Even though stem cleaning with carpet steam cleaning equipment can kill all allergens, dust mites it would be advisable to manage dirt the good old fashioned way, clean your shoes at the door mat and take off your shoes when entering the house. That should make your home a much safer environment to be in. And perhaps you may consider over and above purchasing a carpet stem cleaning equipment with an air purifier for a cleaner healthier home.

Automated Drafting

Thu, 29 Jul 2010 09:55:53 +0000

Automated drafting or computer graphics is a way of converting the computer's impulses into engineering documents and, conversely, to translate the operator's instructions into electronic data.

In many of the more sophisticated systems, we need to know little about computer programming in order to control the human-machine effort.

In general, automated drafting or computer graphics includes any device which converts computer language to people language, or any device that converts people language to computer language, with the intent of solving problems by creating graphical images.

Most automated drafting machines are easy-to-operate, self-contained, automated systems for the direct translation of rough sketches into high-quality finished ink on vellum drawings.

The system is designed for simple, real-time operation by draftspersons or designers and is particularly useful for producing drawings containing repetitive zymology and text. It can be installed in a drafting room since it does not depend in an outside processing source. Applications include logic diagrams, technical illustrations, electrical and electronics schematics, piping and hydraulic layouts, and many other drawings.

Automated drafting involves the creation of hard-copy engineering drawings directly from the CAD data base. In some early computer-aided design departments, automation of the drafting process represented the principal justification for investing in the CAD system. Indeed, CAD systems can increase productivity in the drafting function by roughly five times over manual drafting.

Some of the graphics features of computer-aided design systems lend themselves especially well to the drafting process. These features include automatic dimensioning, generation of crosshatched areas, scaling of the drawing, and the capability to develop sectional views and enlarged views of particular pan details. The ability to rotate the part or to perform other transformations of the image (e. g. , oblique, isometric, or perspective views), as illustrated in Fig. 6.7 can be of significant assistance in drafting. Most CAD systems are capable of generating as many as six views.

Easy Ways In Prevent Water Damage In Your Home

Thu, 29 Jul 2010 09:55:52 +0000

Water damage is often one of the costliest and most troublesome problems which can plague a homeowner. It can destroy almost everything in a home from hardwood to carpet to expensive or valued possessions, and can take months to fix. But still it remains a problem that few people put much thought into until it becomes too late. Thankfully it is usually possible to avert this type of damage by taking the proper precautions. Below are five simple and easy precautions one can take to drastically reduce the risk of one's home being damaged, and save a large amount of money, time, and anguish.

Keep All Appliances Updated

Make sure all your appliances that use water, like a washing machine or hot water heater, are relatively new, as old ones are prone to breaking and malfunctioning. It is generally wise to replace appliances approximately once every ten years. Don't wait to replace it until it blows out and it becomes too late.

Regularly Inspect Hoses

One of the most frequent ways that damage is caused is a malfunctioning hose. Fortunately this is an easy problem to avoid. Be sure to check all the hoses attached to your appliances on a regular basis for breaks, holes, bulges, or kinks. If any of these are found the hose must be replaced immediately. This is usually very cheap and easy to do. It may be better to switch away from rubber hoses altogether and replace all your hoses with more durable stainless steel ones.

Shut Off Appliances When Gone

Never leave the house while a dishwasher or washing machine is still running. Usually if you are at home and something goes wrong with an appliance's operation, you will be able to notice and shut it off before any real damage is done. If you leave these running while away, what could have been a simple problem to avert can turn into a huge mess and a large amount of damage done by the time you get home.

Upper Level Appliances

Take extra precautions when it comes to air conditioners, dehumidifiers, or anything else with water that is kept on top the roof or inside the attic. Unlike a basement appliance, which if it leaks will probably only do damage to its immediate area, a rooftop or attic appliance will allow water to seep all the way down through walls and floors, damaging everything in its path. Rooftop appliances are even more dangerous because of their constant exposure to weathering and destructive elements. These should always be checked annually and repaired immediately if any problems are noticed.

Install Water Alarms

Almost everyone has the foresight to install smoke detectors, but few people consider a water alarm, which works on the same principle. This is a simple device that can alert you to water leakage, enabling you to stop the problem before it becomes a major disaster. It is usually no harder to install than hooking up a garden hose to a nozzle would be.

Water damage can largely be prevented simply by using these simple methods. You will save greatly on money, time, and personal frustration by being proactive. Even if you do not foresee any problems, these easy measures are a highly preferable alternative to finding an unexpected problem and having to deal with it afterward.

Pre-design, Design & Detailing Costs Of Constructing Steel Structures

Wed, 28 Jul 2010 09:05:02 +0000

Reducing the production costs of the Steel structure is crucial in the complete development of a building or industrial structure. To find out possible cost savings, the engineer needs to have thorough knowledge about costs of Steel construction and software that helps him prepare an estimatation.

Design costs involves three components:
1) Pre-design cost
2) Shop design cost
3) Steel Detailing and working drawing costs

In the pre-design stage most of the time and efforts are required for main frame design and the stability analysis of the structure. The structural engineer focus only on connections that affect the stability of the structure. This includes rigid or semi-rigid connections with basic calculations.

In shop design stage the engineer needs to detail all the beam-column-end plate connections that affect the stability of the steel structure in detail.

In steel detailing stage the steel detailer or draftsman dedicate most of his time on detailing connections in the steel structure. Advance CAD tools such as Tekla (previously Xsteel) and AutoCAD with their 3D modeling and automization capabilities help draftsman to set up the steel frame. Detailing of other connections and printing and plotting of the drawings is carried out subsequently.

Use of 3D Modeling for detailing steel structures has become the standard worldwide. The 3D system comes with specific modules dedicated to each job such as pre-design, detailing, erection schedule, etc to help detailer reduce production time and cost. At present these systems are mainly used for the detailing and sometimes for estimating. Two main benefits include:

1) The fabricator gets a clear understanding of what is estimated - resulting in less errors
2) 2D shop drawings can be generated automatically
3} Connection design with 3D analysis help detect clash

Promoting the advance technology in steel design makes the fabricator more competitive. The above mentioned advantages helps fabricator reduce delivery schedule, improve design quality and overall profitability.

The Advantages Of A Tin Roof

Wed, 28 Jul 2010 09:05:01 +0000

A tin roof, although not the most modern type of roof, has several positive aspects and is worth considering when building a new house.

A tin roof is more affordable, but this doesn't mean it's not resistant and won't successfully protect your home against rough weather. On the contrary, it will probably last more than other, more modern types of roofs, without any major repairs being required. Tin is also a very light material (which means that it puts less pressure on the structure of the house), yet it provides effective protection against bad weather and hot temperatures. If you choose it, you'll most likely never have to deal with a leaky roof and won't suffer too much from the summer heat.

However, tin roofing also has an important drawback: it's very noisy. That's why insulation is necessary if you're easily bothered by the sound of rain falling on tin surfaces. It can actually get quite loud and unpleasant, despite a certain poetic value, so soundproofing is very much recommended.

Some people don't like the look of a tin roof, but others do and the truth is it can look rather nice when it's suited to the whole architecture of the house. On older houses particularly, tin roofs are esthetically pleasing and have a certain charm that other types of roofs lack, but many modern houses also look very good with tin roofs. This type of roofs also come in various colors, so you can pick the one that you like best or that is more appropriate for the architecture and style of the house you own.

If you can't decide on the right type of roofing for your new house and you want something that looks good but isn't very costly, then maybe you should get a tin roof.

What’s New In The Home Printing Market?

Tue, 27 Jul 2010 09:01:29 +0000

Sometimes, it really doesn't pay to joke about what things will be like in the future. If you have ever stumbled upon the blogs that dredge up magazine articles and things from the first half of the 1900s, and seen how scarily similar some concepts of the future were, you'll understand! We've joked before about being able to buy a printer that can also toast your ham and cheese sandwich for lunch, and looking at some of the developments in the home printing market recently, we might not be far away from that eventuality! Check out what's new in the home printing and ink cartridge refill market, from news in early 2010.

New printer security solution from Ricoh for sensitive documents

It seems like a business-oriented printer solution - making sure that unproductive employees can't waste company ink refills and paper on their personal jobs. However, if you've ever let your kid use the computer, and come back to find hundreds of colour copies of their Paintbrush drawings on the ground, you'll understand why this is just as useful for the home market! It's a quirk of the market, but ink cartridges can cost more than exotic champagne - so why not protect them!

World's smallest laser multifunction printer launched

The world's smallest laser multifunction printer has been doing the rounds of launches across the world, and at the end of February had made it to Nigeria. Samsung's SCX4300 measures only 409 x 362 x 232 mm, so takes up less space than most ordinary laser or inkjet printers, while offering the multiple functions of copying and scanning.

Application makes it possible to print and reassemble large posters at home

Easy Poster Printer is a freeware, Windows-based tool for slicing and dicing your enormous photos into smaller A4 (or customised) sizes, so you can print each of them individually and reassemble them as an enormous poster. Even fairly low quality (low DPI) printers can do a great job on enormous posters, simply because they are viewed from so far away. Make sure you have plenty of ink refills or printer cartridges at the ready to use this one, though!

World's first web connected home printer launched

HP is one of the market leaders for printers, and they recently launched the world's first web-connected home printer. You receive apps preloaded onto the printer, and can download additional ones from the app store. You view and interact with the apps on a touch panel, helping customise and print content the way you want it. This is when that ham and cheese toastie starts sounding pretty close!

3D printing

This is not quite in the range of the home user just yet, but we couldn't resist adding it in - the concept is so futuristic! 3D printers have only been available for a short time, but have already found their way into many major architectural, R&D, and product design studios. You feed the printer a CAD drawing, it creates a 3D plastic object for you .. mind boggling!

Home printers are gaining features faster than you can say Should I get a HP or Epson?'. The future of home printing, ink refills and paper technology is coming .. perhaps sooner than you think.

Promotional Tape Measures For Your Construction Materials Business

Tue, 27 Jul 2010 09:01:28 +0000

Many companies face the same problem when they first start out: effective and realistic advertising. While some businesses might have the money to put up for expensive marketing schemes, the reality is that most do not. A great alternative to expensive marketing is to take matters into your own hands, especially when dealing with your construction business - after all, its a hands on business to begin with.

Promoting your construction business doesnt have to be difficult and can often be a rewarding investment of time for both you and your company. Promotional tape measures are a great way to think along the lines of your clients interests. Whether youre looking at promoting yourself as a general contractor or looking to involve yourself and your business in the Do It Yourself aspect, logo tape measures are an excellent and effective marketing tool as well as an excellent practical application tool.

Working with people who take measurements daily has perhaps opened your eyes to this idea and its a good one to have. When you couple practical application with your advertising it will go much further than just a one-sided campaign or ad in the local newspaper. Working with custom tape measures as a promotional tool will allow your company to not only get their name out there, but also invite clients to keep your name in their home.

Whether youre looking at a big ad event or seminar where you will hand out promotional goods its always a good idea to hand out promotional items that make sense when used in reference to your business. Think about it you wouldnt hand out muffin cups for your home improvement business, would you? Business cards are also a useful way to go, but dont have the same effect a useful promotional item does like imprinted tape measures.

Its ideal to put something with substantial weight and thought in your clients hands before you part ways. Lets say you are at a seminar with several other businesses that specialize in the same genre of work your own company does. If youre competitors are handing out business cards or flyers the chances that a potential client will remember then compared to your tape measure are very slim. The key to getting into your potential clients heads is to think like a consumer and ask yourself what would work better for marketing a piece of paper or an actual object?

While it might be one thing to get into your clients hands, its quite another to be invited into their home and begin a business deal with them. If youre in the construction business logo tape measures are one of the best means of advertising and just plain make sense in the ways of promotional tools. If you havent all ready thought about using promotional tape measures, then you should seriously consider them as a way of marketing. Marketing is nothing if it isnt effective, after all, and effective marketing could mean the potential success of your construction company.
