The current version of ADT 2006 supports both imperial and metric content and detailing components, but the metric content is organized in the UK specification format only. In Canada, we are often required to provide drawings in metric units. Why is the metric content not available in the Masterformat organization? Although imperial content scales to metric in ADT 2006, the functionality of metric content for annotation routines is not available in the Masterformat system. This leaves a gaping hole in the functionality of ADT 2006 when clients require metric drawings.
