Construction CAD Drafting much more than 40 years ago, engineering and construction firms had dedicated in-house departments that did all of their design and drafting work. For firms that were not large enough to enjoy in-house drafters, the work was routinely contracted out. Blueprints were created by hand using pencils and geometric drafting tools; the older generation of architects and engineers will fondly remember their T squares. For those who were not professionals in this era, it is still easy to imagine the immense amount of time, manpower, and money that went into creating drawings and blueprints, even for relatively simple works.
All of that changed with the introduction of computer aided design. CAD drawings had the distinct advantage of being able to expedite and even automate many aspects of drafting that otherwise took entire departments days to complete. A single person using the software package could create these drawings by themselves in many cases. While drafting departments slowly disappeared from the construction industry, a growing CAD library and technological advances ultimately benefited construction firms.
Computer Aided Design Features That Drive Industry
Computer aided design now contains many more features beyond mere digital drafting. Today’s software is capable of generating a three-dimensional rendering of a structure or building of any size or shape. This virtual model can be manipulated and viewed along any angle rather than having a series of drawings drafted from different perspectives. Virtual structures can be used to conduct feasibility studies and any other number of useful calculations to determine the risks of a given draft. Finally, all of the properties and dimensions on these drawings are easily modified to allow for experimentation, revision, and optimization. The full list of the features is awe-inspiring.
Computer Aided Design’s Many Uses
Computer drafting software can be effectively used in many roles at any end of the design and manufacturing process. Virtual drafting allows for an open environment for ideas to play out without the need for creating a series of prototypes or expending any tangible resources. CAD drawings are used in modeling nearly any industrial product, building, structure, or system that could be conceivably used in the construction industry. However, computer aided design’s usability goes much further.
Anatomy Of Computer Aided Design Users
Another way of understanding how computer aided design is used and how it has advanced the industry is to look at how many different people can utilize CAD drawings in their job functions. Architects use drafting tools to construct buildings, civil engineers use it to design bridges, and mechanical engineers can design industrial equipment. Engineers in all professions utilize this tool in the process of creating conceptual designs and corresponding scheduling and process control in the manufacturing step of industrial products. City planners and artists can use this virtual space to layout design elements and evaluate the aesthetic and utility of a particular layout.
Ultimately, these drawings and access to extensive resources in a comprehensive CAD library have been essential in advancing the construction industry.

~~~ About Autodesk and AutoCAD ~~~
For many years now, the CAD Drafting Company has been dominated by the a single piece of outstanding software: AutoCAD.
AutoCAD is a CAD platform designed by Autodesk, Inc, and arguably the most-used (and most respected) program of its kind. AutoCAD is used to make a computer draw two and three-dimensional technical drawings such as those used in building construction and product manufacturing.
AutoCAD has been steadily evolving over the years to be seamlessly compatible with the rest of the software universe. For instance, in its latest version, drafting team members scattered over the globe can collaborate effortlessly over the Internet.
~~~ AutoCAD and Competition ~~~
In the domain of 2D and 3D drafting, AutoCAD is miles ahead of any competition. Rival programs have less than 50% of its drafting commands. Most importantly, competing platforms hang when file size exceeds a few megabytes, often corrupting the data file in the process.
~~~ Recent Events ~~~
Strange things have happened recently:
(1) Autodesk purchased Alias, a company specialized in, among other things, high-end animation software, ‘Maya’ being its flagship platform in that area
(2) Autodesk crashed the price of AutoCAD by EIGHTY PERCENT in Asia
(3) AutoCAD has begun downplaying AutoCAD 2D usage in its press releases
~~~ What do These Events Foretell? ~~~
We strongly believe that AutoCAD will lower the priority of its 2D CAD drafting software development. Instead, it will devote more resources to animation software development.
Animation is used by two main market segments: their existing architectural/engineering customer base and the media/entertainment segment.
Our intuition tells us that Autodesk has got the heady scent of cash wafting in from the future, and that the source of the fragrance is the second segment: media/entertainment.
The potential profits from this area are likely to be several times those from the first segment and Autodesk will, in effect, soon be moving from downtown San Francisco to a premium spot in heaven.

The CAD Conversion Company process starts with a high quality scan. When a paper drawing is scanned, the resulting digital file is a raster file. The large format scanner used to scan paper drawings for raster to vector conversion should be a scanner that is capable of providing a high quality image. Image quality is everything here. If two lines are muddied and appear as a single line in the scanned drawing it will be difficult, if not impossible, to know that they should be separated when the scanned raster image is converted to a vector image. Once you have the best scanned raster image possible, rectify the image to make sure it is aligned correctly, scaled correctly, and that it measures correctly on all axes points.
In order to work with a digital file in a CAD (Computer Aided Design) system, the scanned raster file needs to be converted to a vector file by a process called raster to vector conversion or, simply, vectorization. According to Wikipedia, “vectorization refers to the process of converting raster graphics into vector graphics.” In very simple terms, this means converting pixels, which are dots of color (raster) like this… into lines (vectors) like this __________. It’s important to note that when you enlarge a raster image, the dots or pixels begin to break apart, and you lose the clarity of the image. (Think about enlarging a photo taken with your digital camera). On the other hand, a vector image can be enlarged indefinitely without loss of integrity, because it is made of lines, arcs, polygons, etc.
But how exactly to convert from raster to vector? There are many different conversion methods. There are commercially available raster to vector conversion software packages from companies like GTX, Hitachi, I/Vector, and Softelec. Some conversion service companies have written their own raster to vector conversion routines. Unfortunately I have found that one raster to vector conversion product does not fit all. It is not uncommon with 100 drawings, that 30% are converted via one (1) method, the next 40% need to converted via a different method, and the remaining are hand redrawn.
Please do not be misled with raster to vector software vendors promising ‘automatic raster to vector conversion’. Simply put, it is not true. These products are tools – and only tools. They all can help in the conversion process, but they are not the cure-alls they claim to be.
Generally, I have found that the most reliable way to get “CAD Perfect” digital drawings is by using an experienced raster to vector conversion service. Make sure the firm has proven and verifiable capability to provide converted files that can be brought into your AutoCAD, Microstation, or other CAD program that you use. Make sure that the conversion service you choose is able to provide vector files that are easily editable in your PC CAD, CNC, GIS or other program. Finally, confirm that the raster to vector conversion service that you use provides quality control and a satisfaction guarantee. The work should be guaranteed to be 100% correct, 100% of the time. No exceptions. No excuses.

Term “Paper to Cad Conversion” within the AEC industry means the process of converting a paper drawing into CAD format. There are some very similar terms: CAD conversion, PDF to DWG, raster to vector, vectorization, paper-to-cad, and some more. “CAD” stands for Computer Aided Design. However, in the context of paper to CAD conversion the term “CAD” implies professional drafting software file formats. As for the term “paper”, it refers to a single paper drawing or a set of architectural, civil, electrical, HVAC, structural or other drawings.
Three ways of paper to CAD conversion can be used: automatic, semi-automatic, and manual. The first one is performed by scanning a paper drawing and converting it into a CAD format using raster to CAD conversion software. This approach has some drawbacks as long as not every raster to CAD conversion application can recognize text, patterns and dimension lines. As a result the CAD file can contain a mess of lines and dots instead of circles, lines, arcs and text as text separated into several layers. The second way adds manual error correction to automatic conversion. The third approach involves complete redrawing of the original drawing in a CAD application.
There are several reasons why paper to CAD conversion is needed. First, electronic drawings can be easily edited in professional software. Secondly, such drawings can be stored and searched on a local or network disk so those specialists who need a CAD document can access it much faster as comparing to working with paper drawings. In addition to this, CAD documents do not require special room for storage, they can be easily backed up, they are unlikely to be damaged in emergency, and they are not aging with time.
To sum up, conversion from paper to CAD can be useful to those CAD companies which have a large archive of paper drawings and want to convert them into electronic format. It is recommended to use the services of CAD services providers – companies which specialize in paper to CAD conversion. Using their services a company can have its paper drawings converted at the shortest possible time and save money on purchasing CAD applications and training its specialists.

In industry field there are so many types of drafting like 2D drafting (Civil, Architectural & mechanical) 3D Modeling & Rendering (Architectural & mechanical) in Auto CAD. There are many companies in market who provide high quality, precise and quick architectural drafting services for architects, engineers, builders and contractors at a reasonable price.
Drafting work need some specialties. Here are some of them. Architectural drafters draw architectural and structural features of buildings and other structures. Drafter may have specialize in a different type of structure, such as residential or commercial, or in a different kind of material used, such as reinforced concrete, masonry, steel, or timber. For example, Civil drafters prepare drawings and topographical and relief maps used in major construction or civil engineering projects such as highways, bridges, pipelines, flood control projects, and water and sewage systems.
2D Drafting is technique of creating accurate representations of objects for manufacturing and engineering needs. With the help of 2D drawings we are able to fully and clearly define requirements for concepts or products. 2D drafting is essential for accurately and unambiguously capture all the geometric features of a product or a component and thereby convey all the required information that will allow a manufacturer to produce that component.
Today there are many companies used 3D drafting, 2D drafting services for their work and still no of companies are going to increasing day by day. 2D drafting systems are big improvement over traditional hand drafting, doing away with all the complications of scale and placement on the drawing sheet. One extension of 2D drafting is 3D wire frame. In 3Dwire frame each line has to be manually inserted into the drawing.
Compare to 3D drafting 2D drafting is relatively inexpensive. 2D drawing does not work easily with downstream systems like purchasing and manufacturing.
2D drafting will continue to find its uses in the future. However, the need for stand-alone 2D drawings will go down as the need for simulation and advanced visualization increases. 2D drawings will continue to be used as a point of reference and for inspections because they are more widely recognized and understood.

You probably have heard about CAD rendering, and if you are not a graphics artist you may not be aware of just how often and in where it is used. It might surprise you just how often and in what applications CAD rendering appears.
Architectural rendering is not just for architects despite its name. Car manufacturers, landscapers, engineers and others use CAD rendering or have it done for them. It allows them to see flaws in design and perspective before costly errors are made in real time production.
Architectural CAD Design is very detailed oriented and incorporates realistic lighting and textures to give a much more realistic feel to the modeled object. Virtual walk-throughs can be created for the web to give prospective buyers a real feel for the design. Car designers are bringing their models to life in three dimensions before production with the aid of architectural rendering.
CAD or computer aided design can be as simple as a 2D representation with little detail or realism to as complex and versatile as 3D parametric solid modeling. It depends on the use the end product will be put to, as well as the skill of the CAD operator. The simplest are 2D or wire models.
There are many brands of CAD software available. They range in cost from freeware (high learning curves with low end simplistic results), all the way to high end software with sophisticated engines that can literally take a design from the drawing board and breathe life into it. Though, even the expensive software may also have high learning curves because of all the options and details that can be imported.
If you are a designer you may not necessarily be a software genius. CAD software takes quite a bit of skill and usually either schooling or hours upon hours of trial and error. Architectural rendering or CAD can be outsourced and sometimes this is the wisest choice in terms of time and expense.
Should the option of a rendering service appeal to your circumstances and very possibly to your budget, then it is important that you view samples of their work, inquire as to their delivery time, and balance costs. Make sure you choose a reliable service and beware any that promise too low a price or only offer stock rendering. Good services will get as much information as possible before giving a price beware of any that offer a custom architectural rendering service for a flat fee or the costs seem way too low. In the case of architectural rendering as with most things, you usually get what you pay for.
Should you decide to learn to use Architectural rendering software then set aside sufficient time for the learning curve. Invest time in finding tutorials that will shorten the learning time. Make sure your software is applicable for the use you want to put it through and lay in a good stock of patience.
