Since there are a large number of options available in the code generation process, ACGUI allows settings to be saved in project files for reuse. Project files can be created, opened, and saved from the "Project" menu. If no project file is explicitly used, a dummy project will be implicitly created and can be saved to a file at a later time.

Project assets, such as ASN.1 schemas and generated source files, are visible in the "Project" window. Project settings can be changed via the Project Settings window, accessible by selecting "Project->Project Settings..." from the menubar.
