    Click here for a list of what's new in version 7.

    Features marked in the list below are available in the Pro version of Scan2CAD only.

    Scan

     

    Scan from inside Scan2CAD using TWAIN (Acquire).
    Use any TWAIN-compliant scanner of any size.
    Use any scanner of any size whose software saves standard raster files.
    If you have a desktop scanner, you can scan large drawings as a series of "tiles" that you can assemble, merge and vectorize inside Scan2CAD:
    1. Use Acquire to grab scanner-sized "tiles" from large drawings.
    2. Alternatively, load tiles that have been saved as separate raster files.
    3. Re-assemble the drawing using accurate move, deskew and merge tools.
    4. Tidy up and vectorize the drawing in the normal way.
    5. Save As DXF to the same size and scale as the original drawing.

     


    Load and save raster images

     

    Load and save:
    • BMP
    • CALS (Type 1 - .CAL, .CALS, .GP4, .CG4, .MIL)
    • GIF (not recommended)
    • IMG
    • JPEG (not recommended)
    • PCX
    • PNG
    • TIFF
    • GeoTIFF

    Scan2CAD does not support multi-layer/page TIFF files.

    In theory the maximum raster image size that Scan2CAD will handle is 32,000 x 32,000 pixels.

    This equates approximately to a 13.3 foot x 13.3 foot or 4m x 4m drawing scanned at 200 dpi or an 8.8 foot x 8.8 foot or 2.7m x 2.7m drawing scanned at 300 dpi. For most drawings 200 or 300 dpi is optimal.

    In practice the maximum raster image size that Scan2CAD will handle is determined by your PC's system resources - for example the amount of physical and virtual RAM it has.

    Load black and white, grayscale and color raster images - 1 Bit, 4 Bit, 8 Bit and 24 Bit.
    Convert between raster file types - e.g. load a raster image as a BMP file and save it as a compressed TIFF file to save disk space.

    Manually reduce the number of colors used on the image. Display a histogram of colors to help choose which colors to reduce to.
    Decrease color depth.
    Change one color on the raster image to another.
    Change the palette so that it matches the palette in your CAD program.

     


    Vectorization - vector recognition

     

    Identifies continuous lines, dash and dash dot lines, arrow lines, hatch lines, polylines, circles, arcs or Bezier curves and text.
    Choose from ten supplied default conversion types for quick and easy results - use the one that best describes your drawing:
    • Architectural.
    • Electrical.
    • Mechanical.
    • CNC Profile.
    • Site Plan.
    • Contour Map.
    • Sketch (traces every detail of a raster image using many short lines).
    • Outline (outlines solid areas of black or color).
    • Scanline (creates an exact vector copy of the raster original. The vector image is made up of many closely spaced parallel horizontal lines).
    • User (your own user-defined settings).

       

    Default conversion types give good results on most drawings but easy to use settings let you control the conversion process if you want to. Settings include:

     

    Center line tracking, outline tracking or both.

     

    		   
    Center line

     
    Outline

     

    Control whether vectors follow the raster image loosely (produces less vectors) or closely (produces more vectors).

     

    		   
    Loose

     
    Close

     

    Specify a Gap Jump Distance - Scan2CAD jumps over any gaps in the raster image that are smaller than the value you specify, allowing continuous vectors to be produced over broken raster lines.

     

    		   
    Gaps

     
    Gaps jumped

     

    Specify a Loose Ends Length - Scan2CAD removes "loose end" vectors shorter than the value you specify.

     

    		   
    Loose ends

     
    Loose ends removed

     

    Choose to have vectors join or pass at intersections.

     

    		   
    Join

     
    Pass

     

    Align the vectors to a grid.

     

    		   
    Not aligned

    Raster
    Vector
    OCR conversion settings include:
    • Set Character Rotation so text is recognized the right way up.
    • Choose Character Set - Standard recognizes all characters, Number recognizes numbers and symbols only.
    • Split touching characters - may improve text recognition where raster characters have bled into each other.
    Convert text on the whole raster image, or just part of it. Convert text on different parts of the image using different OCR conversion settings.
    Convert text separately or at the same time as other drawing elements.
    Train Scan2CAD to recognize a wider range of fonts, including your own non-standard (e.g. hand drawn, stencilled) fonts.

     


    Vectorization - batch vectorization

     

    Specify multiple raster images for conversion at a convenient time - like during lunch or overnight when you are not using your PC.
    Batch process includes pre-conversion raster tidy up options - Speckle Removal, Hole Removal, Thicken Line, Thicken Pixels, Smooth.

     


    Create vector TrueType font outlines

     

    1. Select a font.
    2. Write some text.
    3. The text is converted to 100% accuracte vector outlines that you can export to your CAD or CNC program as DXF.

     


    View vectors

     

    Zoom into a selected area; zoom about the cursor position; zoom about the screen center; zoom extents; step back through your last ten views.
