To use the "two click measure" tool, first click on the point you want to measure from and then on the point you want to measure to.
The example below shows how to measure the recess for the window.
Use the two click measuring tool to easily measure from the center of one pipe to another, even when they are not at the same height.
In the example below, the tool measures from the center of the sprinkler to the center of the ventilation duct. It also measures the distance between center of the sprinkler and the suspended ceiling, and the distance from the center of the sprinkler and the underside of the slab above.
Another advantage of the two click measuring tool is that it's easy to measure from the center of a horizontal pipe to the center of a vertical pipe.
In the example below we used two click measurement to capture measurements from the center of the vertical drain pipe to the center of the horizontal ventilation ducts on both sides. The tool also measures from the center of the vertical drain pipe to the edge of the steel column.
