It is just for this reason that computer programs are a wonderful tool calculating building materials lists. The computer could care less what is happening, it is just another math calculation to run.
By allowing the computer to build the materials list, you also save yourself time. Computer can run through an entire building in a matter of minutes, whereas is would take a person a couple of hours.
As you know from years of working with tools, it is extremely helpful, even essential to use the best tool for a job. Anything else will cause you to take more time, or end up doing the job in a less than perfect manner. A building materials calculator is the same way, and the best tool for the job is construction estimating and takeoff software.
