Building estimation and costing software is another installment of Autodesk in the field of designing. This software is used to create a more accurate estimation of the building material used in the construction. This software helps us to provide the material cost of the project, hence we can have the project cost of any structure through building estimation and costing software. This software is working on two module – the first one is thermal takeoff tool, which is used on a 2D plane, in which we can apply various tools like – Area, Linear Backout and count takeoff tools. The module of the automatic Takeoff tool while required a 3D module to calculate the estimation. This is the only software we have which can estimate the 2D & 3D structure simultaneously. There are various methods to calculate the estimation which students learn during civil engineering like long wall method, short wall method, but in this software, we just have to select the required area and then have to apply the formula of that particular material. In this software firstly we have to create work breakdown structure and then make selection of each entity and then have to apply formula and finally user have to create assembly in which user add each material and there he/she will give its cost and then final report generation will provide us the Gross estimation and the costing of the project.
