Express Workshop

The Express Workshop tutorials focus on specific areas of AutoCAD MEP functionality, and highlight powerful featuresthat are integral to the most common MEP workflows. Each tutorial demonstrates tools you can use to complete tasksthat are common to an overall workflow. When you have finished these tutorials, you will have a basic understanding ofthe AutoCAD MEP design and documentation tools, as well as some of the best practices that help you efficiently designand develop an MEP project.

These tutorials are intended to be used with the AutoCAD MEP Global profile.

Creating Electrical SystemsIn the first half of this lesson, you add lighting fixtures to a drawing and assign them to a circuit, whichautomatically updates a lighting fixture schedule. You then add a switch and wiring.
