Nearly 4,000 global users have analysed thousands of projects across all industry sectors and all corners of the globe to identify and reduce environmental hot spots in their designs.

The eTool for Autodesk® Revit® plugin:

• Enables a fast component take-off
• Allows users to match Revit families with the eTool template library. No necessity to populate your families with materials information, inclusion of construction, maintenance, replacement and disposal impacts.
