Components

Each software component maps to a top level directory in the ACIS installed directory tree. The component directories in your installed directory tree will be a subset of all available component directories, based on your platform and which product(s) you purchased.

Component directories contain one or more subdirectories in which the components files are located (no code is in the top level component directory). Each of these subdirectories generally corresponds to an object library (refer to the Quick Reference Guide for information on object libraries). Most component directories also include subdirectories containing Scheme extensions (subdirectory name *_scm).

The following table lists all the components, alphabetically by their directory names, available for the ACIS product line. For more information about a component, refer to the corresponding Component section.
