SPELL checks the spelling of all text in your drawing, including dimension text. You use one of several main dictionaries, available in different languages. The main dictionaries use a standard word list, which you can customize.
During a spelling check, AutoCAD LT matches the words in the drawing to the words in the current main dictionary. Any words you add are stored in the custom dictionary that is current at the time of the spelling check. For example, you can add proper names so AutoCAD LT no longer identifies them as misspelled words.
To check spelling in another language, you can change to a different main dictionary. You also can create any number of custom dictionaries and switch to them as needed.
You can change dictionaries from a dialog box or by specifying the dictionary name in the DCTMAIN or DCTCUST system variable. For a list of the dictionary file names, see DCTMAIN.
Creating and Editing Custom Dictionaries
A custom dictionary is a list of spelling exceptions that you have identified. The files that contain them can be identified by the .cus file extension. You can use any ASCII text editor to add and delete words or to combine dictionaries. If a word is preceded by a tilde (~), AutoCAD LT always flags the word as incorrect.
You also can create and edit dictionaries from inside AutoCAD LT.
