13. The Verify Table window opens. The View pane (upper pane) displays the original raster text; the Edit pane (lower pane) displays the output from the recognition engine.

    The following example shows typical results for the Recognize Table command.

    
14. Review the results in the Edit pane of the Verify Table window. In this example you would change the $ characters in the first column to the numeral 8 and correct the spacing for the word INCH.
    Attention: Because no recognition engine is 100% accurate, you should carefully review the results in the Edit pane, not just the highlighted areas, and make all necessary changes.
15. Click OK to insert the table as AutoCAD text in the drawing and then press Esc to end the command.

    If necessary, you can use standard AutoCAD commands to move or edit the text.
