There are traditionally three main ways of working on existing drawings, namely:


1.  Manually Maintaining Drawings on Paper
2.  Scanning and Editing Raster Images
3.  CAD Conversion


CAD Conversion offers significant advantages over other methods including:


  Reduced Cost of Revisions
  Increased Drawing Value
  Reduced Drawing Life Cycle Cost
  Reduced Storage And Creation of a Standard Filing System
  Ability to Enhance Company's Competitive Advantage
  Ability to Maintain Consistent Level of Quality for Projects



1. Reduced Cost of Revisions
Revisions done in CAD may be 2-8 times faster than the same revision done by manual methods. And converting drawings to fully vectorised files (instead of just raster images) increases the ease of editing since the user no longer needs to switch back and forth between raster and vector files. Conversion allows the full capabilities of a CAD system to be utilised. And what's best, CAD conversions are low-cost, usually less than $50 per drawing.

2.  Increased Drawing Value
Once drawings are in CAD format, the uses for it increase dramatically. For instance, intelligent CAD files can be used with cost estimating software, facilities management applications such as area calculation and inventory tracking as well as engineering design and analysis software or numerically controlled machining in manufacturing. Intelligent CAD drawings can also significantly reduce the time required to extract data from drawings and enter it into databases which are used for such things as project management, quality assurance, maintenance and material control. Time savings are estimated to range from a few days to even a few months for large projects.

3. Reduced Drawing Life Cycle Cost
Since conversion is a one-time cost, the second and third revisions to a drawing produce even greater savings, reducing the overall cost of maintaining a drawing throughout its useful life. This saving also results in earlier payback for conversion projects. In addition, since physical drawings tend to be huge, cost-effective storage become major issues if drawings need to be kept for a substantial length of time. Electronic CAD drawings can easily be kept on a single hard-disk.

Most building control authorities require professionals to maintain copies of all project drafts and drawings for a substantial period of time (sometimes as long as 10 years!!). For a medium-sized firm, compulsory storage of these physical drafts have been found to take up as much as 2,000 sq ft of space annually. That's enough space to house an additional 20 staff, or the equivalent of paying an additional $10,000 every month. All these can be stored electronically on a single box of CD-ROMs.

4. Reduced Storage Requirements and Creation of a Standard Filing System
Establishing CAD as the standard filing procedure will decrease the amount of engineering time spent looking for drawings, and also the number of lost drawings. Filing more drawings electronically may also reduce square footage being used to store paper drawings. Typically 9 filing cabinets (20,000 pages) or over 3,000 large format drawings can be stored on a single CD-ROM disc and any individual file, word, phrase or drawings can be located within seconds via anyone with appropriate network access.

5. Obtain a Competitive Advantage
Converting drawings to CAD allows a firm to project a consistent, progressive and high quality image to their clients by eliminating the use of outdated manual drafting methods. CAD is recognized as the industry standard in technical drafting and can now be used for drawings which were created before CAD.

6. Maintain a Consistent Level of Quality for all Your Projects
Begin the commitment of quality at the very first stage of any project, even those projects utilizing old and tattered paper drawings. With CAD conversion, company standards such as text fonts, line weights and other drafting standards are enforced. CAD drawings offer a much higher and more consistent level of quality.
What's more, it only costs as little as $50 to convert your paper drawings to CAD. So why not contact us now to find out more!
