### Step 1: Installing the Pcdcat Interface File on the CATIA System

1. Determine on which UNIX operating system the CATIA system is currently running. Supported operating systems are:

q IBM's AIX

q SGI's IRIS

q HP's HP-UX

2. Create a directory called "pcdmis" under a CATIA user directory for installing PC-DMIS files.
Example: /home/catadm/pcdmis

3. Place the appropriate PC-DMIS/CATIA interface file in the PC-DMIS directory of your UNIX workstation. This interface file will be one of the following files, depending on your type of UNIX workstation:

q Pcdcat.ibm

q Pcdcat.sgi

q Pcdcat.hp

4. If you don't have the PC-DMIS/CATIA interface file, download the appropriate one from ftp://wilcoxassoc.com/dci/catia/.

5. Once the file is in the Pcdmis directory on your UNIX workstation, rename the file to simply “Pcdcat” (without any file name extension).
