Performing a Spelling Check
To check spelling within all your text-based objects, including attributes, issue the SPELL command by choosing Spelling from the Tools pull-down menu. When you start the command, AutoCAD prompts you to select the objects to check. If the SPELL command encounters an unknown word, the Check Spelling dialog box appears, and you must choose to replace the word, ignore the discrepancy, or add the word to your supplemental dictionary. If no errors are found, a message box appears, informing you that the spell check is complete.
Specifying the Dictionaries
The SPELL command looks up words in two dictionaries at any given time: a main dictionary and a supplemental dictionary. Several main dictionaries are supplied with AutoCAD; the default is the American English Dictionary. The default supplemental dictionary is SAMPLE.CUS (it contains a number of AutoCAD command words and terms). To change the dictionaries used by SPELL, issue the OPTIONS command. In the Options dialog box, select the Files tab, then change the Main Dictionary and Custom Dictionary File settings located under Text Editor, Dictionary, and Font File Names.
Unlike the supplemental dictionary, the main dictionary file cannot be modified or added to. You can, however, add words to update the current supplemental dictionary.
The SPELL command within AutoCAD 2005 can delve into all forms of annotation, including blocks, to locate misspelled text-type items. It also displays misspellings in xrefs but cannot correct them.
Creating a Supplemental Dictionary
A supplemental dictionary file is an ASCII-based text file that contains the additional words you want SPELL to use when checking for correct spelling. The supplemental dictionary contains one word per line. You can create as many supplemental dictionaries as you want, but you can use only one at time. When you create a supplemental dictionary, be sure to use a CUS filename extension.
