Basic Structural Steel Drawings Useful For Fabrication & Erection

Structural Steel Fabricators that actually prepare the steel structure or building heavily depends on detailed drawings prepared by the steel detailer. The steel detailer produce these drawings using the construction drawings supplied by structural engineer depending on material availability and shop fittings. Below is a brief outline of essential drawings required during structural steel fabrication and erection.

Design Drawings:
These drawings are produced by structural engineers or architects. Design drawings contains all the details required to prepare structural drawings. They provide data on loads, axial forces, moments, and shear forces. It also contain information of each framing member, precise dimensions, location of each beam and column and general notes for reference.

Anchor Bolt Settings:
Anchor bolt plans explain settings of all anchor bolts with regard to the foundations or footings. Typically, the construction of the foundation has nothing to do with steel fabricators job but the masonry plans may contain some items which the steel fabricator need to furnish. They include leveling base plates, anchor bolts, grilles and machinery braces that must be positioned by the masonry person well before the erection of the steel framework. The steel fabricator supply final anchor bolt settings plan to the masonry person to explain he field placement of the anchor bolts.

Column Base Connection Details:
This generally illustrates connections between the steel framing and the foundation. It may contain information like grout thickness dimensions, elevation of base plates and anchor bolt projection, etc.

Detail Drawings:
Detail drawings present details of all connections. It displays the relationship between connected structural members and may contain common assembly and clearance dimensions. Steel Shop drawings are produced from the connection details furnished here.

Shop Drawings:
Steel fabricator uses Shop drawings to fabricate each structural member in steel fabrication shops. Structural steel members are manufactured according to the details and dimensions information furnished in the detail drawings. Standards for shop drawings differ from one fabricator to another but typically all drawings comply with the AISC (American Institute of Steel Construction) standards for structural detailing.

Erection Plans:
The structural drafter prepares Erection plans for the steel structure. These drawings contain important information such as the location of each member or sub-assembly in the steel framing, column base connection details, anchor bolt plans, etc.

Bill of Materials (BoM):
Typically, a CAD draftsman prepares the bill of materials listing all structural members of the steel framing separately. The bill of materials is displayed on all shop drawings and contain information such as required material quantity, erection marks, shop and field fasteners, size of connecting plates, etc.

General Notes:
General notes are required on all steel drawings and provides essential information such as type of steel, size of holes, size of bolts, hole patterns, etc required by the fabrication shop.

Info On Mechanical Drawing And Technical Drawing

Mechanical Drawing is known as scale drawing of a machine or architectural plan or the craft of drawing blueprints i.e. drafting. The variety of lines used in preparing a mechanical drawing is large, and each of them has its particular meaning. Boundary lines outline the shape of an object and its parts. Section lines are used to show intersections and the outlines of shapes within the boundary lines. The central axes of an object are represented by the center lines. Break lines are used to indicate that the entire object is not seen in the drawing. These, together with hidden lines and dimension lines, are used most frequently.

Correct design information and projection are the imperatives of a set of engineering drawings. The skill and dexterity shown by some persons in drawing more accurately, more quickly, or more neatly have recognized value in the preparation of such drawings. Equipment has been invented to facilitate the performance of the manual tasks. Most widely known are the T square, triangle and protractor. Bridge building begins long before ground is broken for the supports. The making of a bolt also starts well before the machinist sets an automatic machine to cut the thread into a piece of metal. Actually, for both projects, much planning and work have been completed before effort to undertake construction begins. In building a bridge, months of preliminary work are required before construction workers and tools meet on the job. Students wishing to become skilled drafters must practice certain standard exercises. There are many kinds of exercises that can be performed to increase speed and develop accuracy.

Mechanical drawings are widely used to create artwork for automotive design, architectural plans, engineering drawings, or electrical circuit diagrams. The introduction of the computer and accompanying drawing applications, such as Adobe Illustrator and Corel Draw (not to mention cad programs), have rendered skill with pen and pencil almost absolute.

Technical drawing is the discipline of creating standardized technical drawing by architects, CAD drafters, design engineers, and related professionals. Technical drawing includes the various fields and technologies foundation electronics, which has in turn revolutionized the art with new tools in the form of Computer Aided Design (CAD).

A technical drawing or engineering drawing is a type of drawing and form of graphic communication, used in the transforming of an idea into physical form. Technical drawings contain geometric figures and symbols to convey the scope and details of the project. Many professions, such as plumbing, use their own suite of unique symbols. Right angles, parallel lines, curves and symbols constitute the technical drawing. To those on the team, each line or symbol conveys a specific about the project.

Drafters are men and women trained in the art of technical drawing. Another term for a person skilled in creating technical drawings is a draftsman, although modern practitioners prefer the term drafter. It is imperative that technical drawings be accurate. If the drawing is off by even centimeters, the actual work may be off quite a bit too. This leads to terrible consequences and costly delays in construction. This type of drawing is used to fully and clearly define requirements for engineered items, and is usually created in accordance with standardized conventions for layout, nomenclature, interpretation, appearance, size, etc.

The process of creating a technical drawing is called drafting or technical drawing. A technical drawing differs from a common drawing by how it is interpreted. A common drawing can hold many purposes and meanings, while a technical drawing is intended to quickly and clearly communicate all needed specifications of a created object or objects.

Drawing Earnings From Your Very Own Web Designing

But sometimes there are certain essential factors which are often underestimated which results in poor trafficking and avoidable of visitors at a site. Before, creating a website design it is advisable to look for a web company that understands well and the nature of your business as well as your targeted customers. Web design in Auraiya will aid you with such problems but before this it is important to understand the flaws which could force the users to leave your site immediately. Certain tips have been drafted in order to give you a clear concept in creating a profitable site.
User-Friendly Navigation:
It is often seen that when a user tries to get into a website, it becomes difficult for him to move further, the reason behind this is inappropriate guiding technology or the problem in navigation direction. At the end it becomes too hectic and time-killing that the diner is forced to leave the website immediately. This results in the decline of audiences and ultimately the website stays on the net unattended. This is crucial for which it must be given prior importance than all. Make sure that the website designer constructs the website keeping the navigation menu clear and easily accessible.
Dial-up clients are least interested in graphics:
Images or pictures are meant to entice visitors to create thick crowd at a particular website but this could be a time taking for dial-up internet users. A website should be created not only for general audiences but also for those dial-up clients. A website that is stuffed with immense graphics often tends to maximize the download time. To avoid such situations the website needs to be optimized by using image editing program which will minimize the files and hence it becomes easier for the dial-up clients to operate thus minimizing the download time.
Avoid unnecessary and lengthy text content:
Lengthy text contents especially those which are not proportionate to the nature of the business or the images would often turn away the visitors. It is always tiring reading lengthy content until if you are not a serious shopper looking for your requirements. Adding to this, if the text contents are irrelevant to the images or vice versa the user might become skeptic about the changes forcing him to turn down the website.
Cross Browsing Compatibility:
One last correction to your website is that sometimes the site fails to open in different browsers. Today, two most reliable browsers are used “Internet Explorer” and “Firefox” but they are not the only one. “Google Chrome”, ‘Opera” Netscape Navigator” and many more are also used but are limited. People around the world would prefer other browsers over “Internet Explorer” and “Firefox” and if your website fails to respond in that particular browser then the chances to lose your customers increases. It is therefore, the W3C validate helps to improve the compatibility of a website on various browsers.
The above tips and correction may be little but they are effective to begin a business through a proper website design.

How Drawing And Driving Are Alike

Drawing hasn’t been the same since B. Edwards published her 1979 book Drawing on the Right Side of the Brain, in which she refutes the mythology that the ability to draw is a genetic gift and proves it is a global skill, much like driving, that once learned is known for life. According to Edwards, drawing requires five basic skills of perception: edges, spaces, relationships, lights and shadows, and the whole, or gestalt (meaning the ability to perceive the character, or essence, of the subject). Edwards has since revised the book twice and believes as strongly as ever that, as she said recently, “Anyone of a sound mind can learn to draw well.”
Not everyone agrees with her premise, namely many art educators and neuroscientists, but Edwards claims it “simply works.” She first encountered the idea while teaching art at Venice High School in Venice, California, near Los Angeles, in the late 1960s. She had trouble understanding why her students had such difficulty learning how to draw, no matter what techniques she used. When questioned, the students would say, for example, that they could see that in the still life the apple was in front of the glass, but they didn’t know how to represent it in a drawing. One day, on impulse, she asked them to copy a Picasso drawing upside down. To everyone’s surprise, the drawings were excellent; the students claimed it was because they didn’t know what they were drawing.

“Completed baffled,” as she says, by this response, Edwards became intrigued by the research of Roger W. Sperry, a neuroscientist who had investigated human brain-hemisphere functions. His finding that the brain uses two fundamentally different modes of thinking, one verbal, analytical, and sequential (left side) and one visual, perceptual, and simultaneous (right side), led Edwards to theorize that the brain shifts from one mode to the other when drawing, and that drawing well is primarily a matter of accessing the part of the brain best suited to that activity. “Sperry’s research provided an explanation for my own experience in the classroom,” Edwards points out. “I noticed in myself that I couldn’t talk to anyone while I was drawing, and I didn’t want anyone to talk to me. From my students, besides their perceptual difficulties, I noticed that they drew childlike symbols related to the names of the objects–a symbolic vase, a symbolic daisy–and then they were disappointed when those things didn’t look like what they Were seeing.” Edwards began to see how language, centered in the left side of the brain, interferes with drawing, which requires the visually oriented right side.

In first discussing Sperry’s ideas with her students, Edwards recalls they soon stopped saying they had no talent for drawing. “They felt freer to try new ways of seeing,” she comments. As she experimented with exercises that focused on the perceptual skills of the right side of the brain, the students’ drawings improved rapidly. “The question of whether they had an inborn talent dropped out, and they learned how to draw,” Edwards asserts. She began to think of learning to draw in the same terms as learning how to read. “The myth that if your mother can draw then you can is like saying that if your mother can read then you can because you’re lucky enough to have inherited the genes. If we regarded reading as we do drawing, we would spread books around a room and see which kids picked them up. We would provide materials but teach no basic skills. In my classes, I assumed that if I gave the students proper instruction, all of them would learn to draw, and this proved to be true.”
Today, Edwards conducts workshops across the country and has just produced an instructional video accompanied by a portfolio that includes all the art supplies and tools for the exercises she prescribes. Edwards’ instruction is not about drawing techniques, but about acquiring the perceptual skills to see as an artist sees, “not naming or categorizing what’s there,” she adds, “but actually seeing what’s there.” The workshops are for people who have never learned to draw and also for people in nonart-related fields who want to find more creative ways of solving problems. As Edwards writes in her second revised version of the book, “My hope is that Drawing on the Right Side of the Brain will help you expand your powers as an individual through increased awareness of your own mind and its workings.”
The exercises Edwards teaches are cumulative, structured in a similar format to learning how to drive. “As in driving you learn how to brake and steer and the rules of the road until they are integrated into a smoothly running skill, in my workshops we teach all the requisite skills for drawing and build upon them,” she says. After some warm-ups to get acquainted with the materials, the first exercise is a contour drawing. “We use contour drawing as a way to get people to slow down and observe complex details,” Edwards continues. She explains that if a person is forced to linger and look at an object, the left hemisphere of the brain becomes bored. “As the dominant verbal side, it insists that it’s already named what you are looking at,” she says, “and you should move on. If you persist, it rejects the task.” As a result, the right hemisphere takes over and the person begins to see the subject with an acute clarity. This experience permanently changes one’s ability to see in the way an artist sees, and the skills of seeing and drawing progress rapidly. The other exercises teach students how to draw negative spaces and choose a “basic unit” for sizing proportions, the mechanics of sighting, rendering lights and shadows, and how to perceive the gestalt of the subject, which is the culmination of the first four skills.
For most of Edwards’ students, the most difficult exercises are the ones on Sighting, which encompasses perspective and proportion. “As in learning to read or write,” says Edwards, “you can’t leave out grammar. Perspective and proportion are comparable in terms of how important they are in learning to draw realistically.” Edwards tackles these difficult lessons with tools that help clarify the concepts, such as a plastic picture plane with crosshairs and a viewfinder. She also gives students a proportion finder, which is shaped like a wrench with a movable jaw that is used for taking sights, and an angle finder, two pieces of plastic fastened with a brad that can be adjusted for accurate measurements. “Eventually students discard the tools,” explains Edwards, “but sighting is a terrifically complicated skill and the tools help them overcome the initial obstacles.”
Despite her success, Edwards has faced severe criticism from some art educators. They claim that she is not teaching art, but just realistic drawing, mining a child’s creativity. Responding with an unequivocal “Nonsense!” she asserts that nothing in the history of art substantiates such an argument. “It’s only been in our century that a person who knows nothing about drawing can become a renowned artist,” she says. “It’s my view, and many others, that the truly great artists of the 20th century, such as Picasso and De Kooning, were masters because of their classical training in drawing. I think criticism from the art education bureaucracy is founded on the fact that many art teachers themselves don’t know how to draw well because realistic drawing skills have not been taught for 30 years.” Edwards points out that she feels this is evidenced in the dozens of art teachers who have taken her course to acquire or repair these basic skills. As for her justification for basing her instruction on realistic drawing, she says that doing so provides a check for how well students perceive what’s in front of them. Later, these skills can be translated into nonobjective and abstract art. “Students can move into any field–sculpture, photography, design–if they have basic perceptual skills,” she adds. “If they don’t, their choices are much more limited.”
Criticism has also come from neuroscientists. “They become very disturbed when educators like myself take research and develop educational sequences from it,” Edwards says. “They believe that since I’m not a scientist I cannot do that, but my argument is that my application of Sperry’s work explains how the processes of the brain relate to drawing.” Edwards, in fact, hopes that scientists will conduct more research to find out precisely why her approach is so effective.

An educator herself, with doctoral degrees in art studies, education, and the psychology of perception, Edwards holds strong opinions on art education and how it is failing students. “The symbolic drawing of childhood has a function with language acquisition,” she asserts. “I do not recommend teaching perceptual skills at age 3. Kids should be encouraged to do symbolic drawings as long as they are still interested in them. Around 9 or 10, however, they want things to look real. They yearn to depict three-dimensional space.” Edwards believes that if children are taught the perceptual skills they need as they mature, they will continue drawing and using the skills as part of their thinking strategy. “If we never taught them to read, they would try tirelessly and then just give up,” she contends. “Without teaching perceptual skills, the same thing happens. We are not meeting their needs.”

Edwards’ ideas on how the brain functions while drawing is important for artists to consider because it suggests ways of maximizing creativity. “The best art is done when the skills are on automatic and the right hemisphere of the brain is doing the work,” Edwards says. “The job of the professional artist is to remember this and set up conditions that allow the mental shift to take place. This often means working alone and without time pressure. It also means that you set up routines that get you into the painting mode. Bring the process up to a conscious level so that you don’t occasionally suffer from artists’ block, which is the left hemisphere having you in its grip, telling you to phone the gas company and balance the checkbook. If you work out a routine and have faith that it will work, you will accomplish a lot. It’s about taking control of your brain.”
Edwards was pleased when the publisher of her book asked her to revise it for a new edition. Over the past 20 years that she’s led the workshops, she’s devised new teaching techniques, recorded observations, and collected data. All this helped to reline and further substantiate her initial theory, making her case for the right side of the brain even more convincing. “Most artists know what I’m talking about at a gut level,” she says. “They’ve experienced it.” And now so have others who may have always wanted to be more artistic, but thought they had no talent. “Teaching drawing has never lost its charm,” says Edwards. It’s easy to see why.
