Revu's built-in measurement tools make it easy to take length, area, perimeter, diameter, volume and radius measurements, count from PDFs and perform area cutouts. Just measure once and Revu automatically calculates all other related measurements for you, including Wall Area. All measurements are automatically tracked in a list that can be summarized and exported to CSV or XML. Use Viewports to set separate X and Y scales, and create Custom Columns to add formulas to the built-in worksheet and calculate costs directly in Revu. Streamline the creation of Custom Column formulas with an expressions-based Formula Editor that provides a list of available functions and variables as you type.
