When Run Menu > OCR recognizes something on the raster image as text, it “masks” or hides that area of the raster image. This means if you then vectorize the image using Run Menu > Vectorization, Scan2CAD will skip over the masked area and will not include it in the vectorization. If this happens, you must go back and turn on View Text Extents.

View Text Extents displays the masked areas by placing dashed boxes around text that has already been recognized using OCR.

Text Extents = off	Text Extents = on

To toggle Text Extents display do either of the following:

Press the T key.

Select View Menu > View Text Extents.
