A scanned or printed drawing can be redrawn as clean CAD, but the result can only be as reliable as the source. Knowing what decides accuracy helps you set the right expectations.
What decides accuracy
- Scale. A stated scale and a few known dimensions let us check the drawing throughout.
- Line quality. Vector PDFs convert far more cleanly than scans of paper prints.
- Dimensions. Written dimensions always win over measured lines.
Redraw, do not trace
Automatic conversion produces broken lines and exploded text. We redraw on proper layers, with real text, dimensions and blocks, so the file can be edited like any drawing made in CAD.
When to check on site
For old or hand-drawn records, a few site checks or a laser scan are worth the effort before the drawings are used for design.
Conclusion
Good conversions follow the written dimensions, flag what cannot be read and are honest about the source. Ask for that, and you will get CAD files you can trust.
