Are the reports compliant with Australian standards?
They sure are - our calculations follow the latest Australian guidelines to ensure compliance without the headaches. Currently, these are NCC and ABCB Housing provisions standard 2022 10.8.3 guidelines and AS/NZ 3500.3 Stormwater plumbing standards. (Constantly stressing over complex regulations and codes is one of the main reasons we built the tools in the first place!)
How do the cutting calculators work?
Simply enter your measurements and the calculator provides instant, precise cuts, angles and reports that ensure you’re adhering to Australian regulations. You can then print, save, or share a PDF with all the details.
How long do the calculations and reports take?
Most are under 30 seconds once you’ve got your measurements!
Do I need to be an expert to use the calculators?
Nope! That’s the whole point - the calculators are designed to be easy for anyone to use, from the apprentice to the boss. Just quick, simple, and accurate calculations without the usual back-and-forth (and hair-pulling). If you can tap a few numbers into your phone, you're sorted.
