Envirobuild’s measurement tool allows for both computer generated measurements of the whole structure, and user generated measurements for specific parts of the structure.
By clicking on the ruler icon you can view computer generated measurements of your entire structure. If your structure is complex with many corners, the custom dimensions tool will give you more accurate measurements.
Find the ruler tool here:

Create user generated custom measurements for specific parts of your structure in the ruler tool.
Toggle the “show custom measurements” button so it appears orange.
