6. While the installation script is running, do the following:

– Enter c to confirm that you want to continue installation under the current directory.

The installation script indicates that the current directory is the Resource directory.

– Enter the CATIA V5 Release Number. This is the version of CATIA V5 on your system.

– Enter the CATIA V5 Install Directory. This is where CATIA V5 is installed on your system.

– Enter the CATIA V5 Environment Directory. This is where the install procedure will create

the environment file for the Elysium, Inc. writer. This directory can be different from the

directory in which CATIA is installed. If the directory does not exist, the install procedure will

create the directory.

– Enter the CATIA V5 Environment Mode. Enter 1 (global) if any user can use the writer.

(You must have root authority to select global.) Enter 2 (user) if only the user performing the

installation can use the writer.

The installation procedure displays the configuration that it will create and asks you to confirm

that you wish to continue. The CATIA V5 start shell shown in the configuration is the shell

script that you will use to start a version of CATIA V5 that includes the writer plug-in; for

example, CATIAV5_B15_with_ABAQUS_Translator.sh. You may want to provide

your CATIA users with an alias to this shell script.
