QUALITY SCANNING:

Creating high quality scans for raster to vector conversion

Is the drawing suitable for raster to vector conversion?

Some drawings - or parts of drawings - cannot be scanned and then converted to CAD using raster to vector conversion.

Typical reasons include:

  • The paper drawing is so faint, dirty or damaged that although it may be possible to make a readable scan for viewing or printing, whatever you do you will not be able to create a clean enough scan for raster to vector conversion.

  • The drawing contains so many overlapping details - for example text written over drawing lines - that even if you get a perfect scan no raster to vector converter will be able to unscramble the information.

  • Text at different orientations.

    Raster to vector conversion cannot vectorize text with intermingled orientations
    Where text at one orientation is intermingled with text at another orientation it cannot be successfully vectorized.

  • Tiny details.

    Raster to vector conversion cannot convert very small details
    Some drawing details are so small that they will never scan well enough for raster to vector conversion, regardless of the resolution you use.

  • "Messy" hatch patterns.
