Manual estimation of the carpet takeoff would be very tedious than the carpet takeoff done using a good construction estimate software. You can just import the electronic drawing of the building to the construction estimation software and make your carpet takeoff with just a click of the mouse. Color coding features of the software helps you to identify the areas that have been already measured. The estimating software has options to set the scales. Suppose you want to calculate square feet then set the scale to that metrics. Just click the area and the software will calculate square feet of that area. Carpet takeoff from an electronic drawing is just easy as a click of a mouse.
If you don?t have access to software for the estimation purpose you can use some of the takeoff tools like the Scale Master or the Ultra Scale Master Pro. These takeoff tools can be used for carpet takeoff too. These tools have built-in options for setting the scales to any of the 91 metrics it already has. Set it to square feet and it will calculate square feet when taking measurements. Complex polygons and linear can also be measured during carpet takeoff. Make use of the take off tools or a relevant software for carpet takeoff.
