You need a basic understanding of Arbortext IsoDraw macros to use IML. See About Macros to review these concepts. To learn more about using macros in Arbortext IsoDraw, see Macros Menu in the Arbortext IsoDraw User's Reference.

In addition, since IML is a programming language, some experience with simple object-oriented/event-driven programming or scripting would be helpful. However, you can still get started writing and editing macros using IML by copying the macro code examples in this guide and modifying them to suit your needs.
