### Step 3: Declaring Your Files

For the CATIA Direct CAD Interface to access a path, that path needs to be defined in a CATIA declaration file There are two files where this can be done. On most systems they are:

"/home/catadm/USRENV.dcls"

"/home/catadm/dec/CATIA.dcls".

Using a standard text editor, modify the CATIA declaration file, Catia.dcls, to define the model directory and/or alias (See "Example of Catia.dcls File on UNIX Workstation").

Note: Normally, you'll only need to edit Catia.dcls, but some situations may require that you edit both files.
