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…)

Ethernet cables are essentially the lifeline of our home networks, and our internet. Almost every home network uses ethernet cables to connect either their modem to their router or their routers to their computers. Ethernet cables are especially important for those users who are still on wired networks, and haven’t made the jump to wireless yet. For those of you that have had to go out and purchase ethernet cables in the past know that these cables do not come cheap for anything over 10 feet or so. If you have to stretch it up to 20+ feet the price increase is exponential, when in fact, it doesn’t really cost that much more to make a longer cable. In today’s post we’re going to show you how to make your own ethernet cable.

Materials For Making Ethernet Cables

• Wire Cutters/Strippers- I’m sure you have atleast one pair laying around, if you followed my article on how to assemble the ultimate PC toolkit you should have a pair in your amazing PC toolkit.
• RJ45 Crimping Tool- This is used for crimping or “terminating” the ends of the cable so they stay attached, you can get these at a radioshack-type store or save yourself some money and get them off Amazon for cheap.
