You’re probably aware that AutoCAD LT has a built-in spell checker, accessible from the Annotate tab of the ribbon, with the SPELL command, or as you go with a dashed red line under misspelled words as seen below: But wait a minute – that word isn’t misspelled! It’s a standard abbreviation. So what to do with it? As always, you have more than one option. You could just ignore it. The red line only shows up in the editor, and it won’t print, so you could just leave it alone. Or you could right-click on the word and choose “Ignore all”. This turns off the red line temporarily, but it will be back. To get rid of it completely, choose “Add to dictionary” from the right-click menu. (Anybody else entertained by the fact that “TYPO” is one of the suggested alternatives?) This is great for adding words one at a time, but there’s also another way to manage your custom dictionary. Start the SPELL command (from the command line or ribbon) and go to Dictionaries. (Notice also that you have a choice of main dictionaries, in case you’re spell-checking drawings in different languages. They won’t help you with the actual translations, though.) In this dialog, you can switch out custom dictionaries (maybe point to one you’ve got on your server), add or delete words from the list (nice of us to put “AutoCAD” in there, don’t you think?) and import other dictionary files. By the way, a “dictionary file” is just a regular old text file with a CUS extension that contains the list of words you want to be considered as correctly spelled. Easy as pie to create, especially if you’ve already got a standard abbreviation list.Go to the original post...
