Saving Form Field Default Settings

To save the current environment variables and form defaults to a file, do the following:

1.Choose Options – Save Defaults.

2.If you want to change the default filename, type a new name in the form.

Note: If you have an existing .cdsenv file, you might not want to overwrite it. Instead, you can write it to a different file and then copy the lines you want to the.cdsenv file.

The Save Schematic Defaults form appears.

/your_directory/.cdsenv

3. Click OK.

The filename specifies the name of the file where the variables and form defaults are saved. The default is a file named.cdsenv in your home directory. If you use this filename, the saved variables are automatically loaded the next time you start the editor.

Note: This form saves environment variables only within the schematic composer environment. The same command in the CIW saves all environment variables.
