By default, the Structure101 Studio model for a C/C++ code-base includes all the source files that were involved in the make process, including all system and third party library headers.

If you are only interested in a subset of this data, you can tell Structure101 Studio to exclude specified files or groups of files, so reducing the overall noise level in the model as well as the associated memory requirements.

This is achieved by adding exclude expressions to the project settings. For example expressions, choose the Examples button from the dialog, or see transformations for more information about expression syntax.
