CAD tip # 7484:

You can use several methods for managing and adding words and terms into these custom dictionaries:

1. In the "Check Spelling" dialog, when the check stops on an unknown word, click the "Add to Dictionary" button
2. In the "Check Spelling" dialog (anytime), click the button Dictionaries, in the dictionaries management dialog then enter the requested word to add and click Add - the term will be added to the current custom dictionary (the picture shows the "novýslovník.cus" file).
3. Similarly to 2) you can add multiple words at once - with the Import button you can load a list of words from another dictionary or from an arbitrary text file (change its file extension to .CUS).

   

4. But you can also edit the custom dictionaries directly using a plain text editor (Notepad) - just open the .CUS file and add, import, change or delete any words.
