# Converter

## Overview

You can set up converters on the compound object. Available converters for a compound object are Unit converters, Scale converters, and Expression converters. Up to 1024 converters can be set per compound object. The setup procedure is the same as setting up a converter for a project.

Note: You can use a compound object property in the Expression converter, but you cannot use a local variable.
