There are millions of drawings lying all around the world. These are invaluable pieces of paper, which have created monuments, buildings, machines and infrastructures. As the time passes by, these paper drawings are endangered being lost to disaster or being lost. There is an urgent need to make sure that all the paper drawings which are lying in offices, godown and secured places to be restored in a manner which will enable them to be with us for a long time.

The various means by which we can convert the old paper drawings to CAD are:
• Automatic conversion using software
• Manual conversion by draftsman
• Precision redrafting
• Scanning and storing

• Of the above-mentioned methods, the cheapest method is to scan the document and store it in a computer. You can get it printed as and when you want it. There are numerous scanning companies all over the place who can scan large documents using highly complex scanning machine. You can scan any old documents and once scanned the document is there with you for lifetime. New York Document Scanning, www.new-york-document-scanning.com

• If you plan to use the CAD file in future for making changes to the original design, which was done on paper, the best method is to get the drawing converted to CAD using draftsman with experience in CAD software. During this process, and as requested, text is re-typed and drawings are re-scaled 1:1. Specified items are also converted to different layers and colors to conform to the drawing standards. The end result of this meticulous process, being a CAD files which is identical to a drawing done on paper and which also requires no further work. http://www.convert2cad.com

• Simple vectorisation is the conversion of a scan or raster image into a CAD or vector file. The process is achieved through the use of software that studies the raster image and tries to recognize and then replace the raster image with lines or vector information. The result is a dxf file, which is layered according to line thickness, line type and text. The image will require some manual clean up, the extent of which will depend upon: 1) The quality of the original 2) The amount of information required from the converted file. (Often clients do not require the title block etc.) 3) The quality of the line work and whether the text was typed or hand written. (more…)

Know Thy SEO Spider

NO I am not talking about the eight-legged hairy creatures of nightmares. These spiders are electronic, used by search engines, and if you ignore them they give you nightmares that will haunt you every waking moment

Search Engine Optimization (SEO) is all about common sense; it doesn’t necessitate specific knowledge of algorithms, programming and classifications. All it requires is a basic understanding of how search engines spiders work. Taking care of the search engine spiders likes and dislikes can prove to be crucial for the health and success of your website.

The Spider at Work

They are called spiders because they crawl over the Web in search of content. Search engines gather data about a website by ’sending’ the spider or bots to ‘read’ the site and copy its content. This content is stored in the search engine’s database. As they copy and absorb content from one document, they create record links and send other bots to make copies of content on those linked documents this process goes on and on. As of now the major search engines have established databases that measure their size in the tens of billions using this process.

The internet age has brought us many wonderful things like shopping from home, unlimited research capabilities, and YouTube. However, this new era has also ushered in a hidden menace: spyware and adware now infect over 90% of the world’s computers. The problem is that these digital viruses, like their biological namesake, change their structure just as quickly as programs can be written to detect and delete them.

These malicious files are also aptly named in regards to their effects on a computer’s performance. This is due to the nature of how a spyware program operates: spyware is installed on your system without your knowledge, and does not leave an icon on your desktop nor can it be deleted using Windows’ “Add or remove programs,” feature. While you browse the web, listen to music, and chat on your computer, spyware runs in the background, keeping track of everything you do and type. This information is relayed back to whatever company caused the software to be installed in the first place. When multiple spyware applications have installed themselves onto a machine, they all continue to run at the same time on top of whatever else the owner is doing. This dramatically slows down even a very fast computer.
