In order to aid with the laborious task of taking quantities off from drawings, we have Electrical Take-Off.
The demand for this product has increased massively as more and more people find their drawings being emailed (or sent on disk) to them at tender stage by their clients, usually in PDF or DWG format.
By simply opening the drawing on screen, with this system all you are required to do is to go around the drawing saying what is there, for example clicking ‘grid switch’ where you find a grid switch etc.
