To Search for and Correct Spelling Errors in the Active Model

Enter a data point in the view window to scan the model.
If there are no misspelled or unrecognized words in the selected text, an information window displays the message, "Spell Check is Complete." If there are misspelled or unrecognized words, the erroneous text zooms in and the Spelling dialog opens with the flagged word highlighted in a text field.
Do one of the following:

or
Make another selection from the Suggestions list box and click Change.

or
Type a new word in the text field and click Change.

The text in the text field replaces the highlighted text, and the search advances to the next unrecognized word. After the last flagged word is modified, replaced or skipped, the Spelling dialog closes.
