Specify whether you want to use the spell check. When you enable the spell check, specify what type of check you want it to perform.
Turn spell check on
Specifies that the spell check will run. If you turn on the spell check, it will run as you type text into various program areas, e.g, in the model, in the attribute table, or in SmartDesign. Texts are checked as you type.
Ignore UPPERCASE words
Specifies that words written entirely in uppercase will not be checked. This is useful if you are using a large number of uppercase acronyms or abbreviations that you do not want to add to the dictionary. Acronyms are terms formed from the initial letters of several other terms, e.g., IT and PC.
Ignore words with numbers
Specifies that words that have one or more numbers appended to them will not be checked. It does not matter where the numbers appear in a word.
