Converts old drawings, blueprints…to CAD.
We specialize in architectural and engineering drawings, as well as working with contractors and builders. All drawings are precision redrafted by hand to create dimensionally accurate, layered, ready to use electronic CAD files… Manual tracing is the only method that insures a quality conversion and workable AutoCAD file. We turn your paper documents into100% dimensionally accurate AutoCAD files.
Paper to CAD Service Includes:
-100% line connections (no scanning or vectorizing)
-100% guaranteed quality, accuracy and turnaround
-Paper or model space
-Fixed price per sheet
-Full-scale 1:1
-Title blocks, blocks, symbols, hatch patterns to match original documents…
Paper to CAD Conversion methods:
There are three basic methods of converting paper drawings into computer files:
1- Precision Redraw (This is the only method we use A-Design Service)
2- Scanning
3- Digitizing
1- Precision Redraw is reproducing the paper drawing in CAD by drawing from scratch, using all the information in the paper drawing. This produces a full CAD file with all the advantages of an original CAD drawing. Layering standards, blocks, standard titles, etc. can all be maintained. Accuracy is equal to or better than the original paper drawing. This is the most accurate and useful method for most architectural applications. This is the only method we use.
2- Scanning produces a bitmap or raster image file. This is usually the cheapest method, especially in quantity, but it has many disadvantages; large file sizes, inaccuracy, "noise" from flaws in the paper drawing. It is not practical to edit the raster file directly although portions can be erased and overlayed with a vector file.
3 -Digitizing is tracing a paper drawing into a CAD file using a pointing device and digitizing tablet. On screen digitizing means tracing a raster image (produced by scanning) in CAD. Both methods produce a vector format drawing file. Drawbacks are the high cost and fast obsolescence of digitizers and the inaccuracy of tracing
