Ahh! my apologies! The distance calculator worked out great! good work and apologies for slighting your software unjustly!
By JL Griffin on 28/01/2015
Hi JL Griffin, this area calculator does work. It measures areas and the perimeter of areas. If you are looking to measure distances then please use the Distance Calculator.
By Daft Logic on 28/01/2015
Wish it worked. I need the dimensions of this building im bidding a job on, but its WILDLY off. like at least a 1.8 to 1 scale. Zoomed in and measured the distance of the length key on the map. google map's listing of 10M read out as 18m on here. an average 9 ft wide parking space measures 17 feet in the calculator. Please fix this. love the concept, but it just doesn't work
By JL Griffin on 28/01/2015
This is a really useful tool. Thanks guys
By Sam Tan on 27/01/2015
Hi Mike, it cannot measure height. All measurements are based on a 2D plan view even if it displays as an isometric view.
By Daft Logic on 27/01/2015
Thank you - today I am able to scale properly, but is it possible to scale the elevation and not just the plan view? I need to get the height of a building and whenever I try, it reverts back to the plan view.
By Mike on 27/01/2015
Hi Alwin, sorry I'm not sure what you mean? Can you explain in a bit more detail please?
