The Dimetris Electrical Engineering Computing Module provides creative freedom to its users, especially in cases where there is little time available and it is necessary to quickly identify the cost of performing electrical engineering works. The solution was first developed for electrical contractors who calculate similar commercial offers without electrical drawings on a regular basis. For example, the customer has purchased a partly finished apartment and needs to install an electrical part in it. In most cases, the contractor does not even have the reference data to calculate at least the provisional price. This is where Dimetris can come in, with the simultaneous design, quantity and cost calculation of electrical installations directly on a PDF plan or a plan of a cadastral file photographed by phone.
