This has been an awesome tool! It takes a while to learn all the capabilities, which I learn more of each job site and with the tutorial videos. It saves me probably on average an hour of work per job as the areas are calculated on site, I can show the client instantly, and I can tell they feel like the calculations ar emote valid from an automated source, and the “human error” is removed. It also shows them instantly on site a representation of the project shape/look. I also really like the ability to store the drawing in folders/files instantly; I can also share these with our crews in a variety of files types, primarily PDF; that said, I really think the ability to save I. A number of other file types is brilliant t so that no matter which architect we may work with , I can export it to them for their design platforms. Great tool, it saves invaluable time and improves efficiency. Good investment for those charged with the field measurements and design promotion of a business! Most notably, for the Keefe lair shape projects, which most are, I can complete a measurement with drawing, in less than 5 minutes, which in the last may have taken 30-45 minutes. It’s also a great communication skill, which helps with language barriers at times for the installation crew; a picture is worth a thousand words, and this in and of itself reduces errors, time and material loss! Wish I would have purchased this last year!!!!
