Our typical Computer Aided Designing services include:

  • CAD Conversion from Raster

  • Microstation Conversion from Raster

  • CAD Designing/Drafting/Vectorization

  • Microstation Designing/Drafting/Vectorization

  • Graphics Designing & reprocation Services

  • Paper to CAD conversion services

  • Automation in CAD through Autolisp programming

We convert paper based drawings to CAD format in DWG/DGN/DXF. If you have a raster art (image, paper) which needs to be CAD/Microstation designed, converted, drafted/vectorized, feel free to try our Engineers with free sample.

We provide drafting services for:

  • 3D Coordinated Plans

  • 3D Modeling & Rendering

  • Architectural

  • Civil

  • Electrical / Wiring

  • Manufacturing

  • Mechanical

  • Patent Drawings

  • Pressure Vessels / Piping

  • Structural

  • Technical Illustration

Since our production facility is located offshore, we can provide you with rates that are hard to beat. Being offshore does not limit us in providing prompt service. With electronic connectivity, we can provide quick turnaround time.

We utilize many different conversion methods. We use CAD conversion products from, GTX, Hitachi, I/Vector, and Softelec. Unfortunately we have found that one R/V conversion product does not fit all. It is not uncommon with 100 drawings, that 30% are converted via one (1) method, the next 40% are converted via a different method, and the remaining are hand redrawn. Please do not be mislead with R/V software vendors promising 'automatic raster to vector conversion'. Simply put, it is not true. These products are tools - and only tools. They all help in our conversion process, but they are not the cure-alls they claim to be. We spend hours, and hours inside of your drawings to get them to be 100% correct.

Our deliverable is a 'CAD perfect' CAD drawing. This includes real lines, arcs, circles, text as text, etc. At a minimum, each drawing is produced with 3-7 layers (levels) and colors. In addition, we often use your layering scheme - at no extra cost.

We also offer as an option to go in and verify and fix each and every dimension in a drawing. So if the original sheet may be off by say 9%, we will go in and actually move any line / entity work required for it to be exactly correct. There is of course a small surcharge of 15-20% for this.

Your delivery schedules are important to us. We are one of the very few firms who can produce CAD work 24 hours per day (3 shifts). For quantities of 1-10 drawings, our delivery time is 48-72 hours. We do not base our fees upon how soon you need the drawings.

We expect you to receive your work CAD Perfect, period. If it is not, let us know and we can fix it - and fix it within 24 hours. If you are ever not happy with our work, we do not expect you to pay our bill. No hassles, no debate.

How do we get started?
The first step to get started is send us:

  • Representative sample of Drawings

  • Drawing standards

  • Estimated Volume of Drawings to be digitized

  • Expected Turnaround time

How do we communicate?
The bulk of communication is done via e-mail which is quickest, cheapest and perhaps easiest way. We respond to e-mails within 15 min to max. 24 hrs. However, we can always talk on phone, by fax or chat online to clear up things.

What is the file size?
The image can go upto 5 MB for a PCX file of A0 size. A similar TIFF file would be 15 to 20 MB.

In what format should I send the scanned files?
The files can be sent in virtually any graphic file format, such as TIFF. For color JPEG / GIF formats are better.


In what DPI should the paper original be scanned?
The paper if scanned at 150 DPI, is able to display almost the entire information visible on the sheet.

Can mail the paper originals?
Yes, you can mail your paper originals from any country directly to our address through FedEX, DHL, UPS etc.

What kind of turnaround time is expected?
The turnaround time could be as low as 24 hours if you email the files, as we work in 2 shifts.

Do you follow your own CAD standards or those which we prescribe?
We set up CAD standards as furnished by the client. However in absence of prescribed standards we use default standards conforming to AIA, OSHA Rules or ISO guidelines.

How can I send the original or markups sheets if an in-house scanner is not available?
You can either utilize the services of a blueprint shop that normally has a scanner, or mail the originals by courier.

Can I use fax machine to send the originals?
Yes you can. Cut the paper sheet into long strips of 8½" size and fax it to our US e-fax number. The width may be increased or decreased so that important information like text and dimensions are clear. This works in 80% of the drawings.

How can payment be made?
Payment can be made in US Dollar, Euros, Pound Sterling or any currency via swift transfer to our account or by cheque mailed to us.

How different does the drawing look if done offshore?
As we use the standards furnished to us, or default AIA/ISO standards, the drawing is the same or better.

Do you spell-check your drawings?
We not only spell-check but also proof read the drawing after a check plot is taken.

What about security of data?
We make every effort to safeguard the computer & paper data files generated in the course of a project. Upon completion of the project, original paper drawings, files can be returned or put in the Electronic vault for future use if required.

Are these services permissible / taxable under law?
These NET enabled IT services are covered under WTO agreement signed by more than 110 countries around the Globe. These services are freely importable and free from customs duties or local taxes.
