1. The environment setup for the CAD tools is different depending on what type of shell is being used.  Type the following command to determine your default shell:
fussell> echo $SHELL
/lusr/bin/bash

In this case we see that the shell type is bash.  

2. Pick the appropriate environment script from the following table based on the results from step 1:
   

   shell	env script
   bash	sh.src
   csh	csh.src
   tcsh	csh.src
   ksh	sh.src
   sh	sh.src
   zsh	sh.src

3. Using the environment script name from step 2 issue the following command to setup the environment variables in your shell:
fussell> source /p/bin/lc35/class_(env script name)

Note: If desired this may be added to your start up scripts instead.
