Growing global trend in the construction industry today is crossing new borders, especially when it comes to accurate and quick designing and dimensioning. Contracting companies and investors have raised their benchmarks regarding time, value for engineering hours and cost effective construction. To meet these demands they need an automation manager like AEC Roads. Accurate and interactive, AEC Roads is a 3D Project designer cum Quantity Estimation and Drawing application that can form an essential part of a Civil Engineers kit. AEC Roads can quickly prepare your Designs, Drawings, Dimensioning and Quantity Estimation. It is designed to speak Engineers language in a quickest possible time on a cost effective way. AEC Roads takes care of budding and busy engineers to use difficult AutoCAD drafting in 3D environment faster with ease. Quantity estimation and bill of quantities preparation are made simple through AEC Roads. From a given input coordinate point files plotted on 2D AutoCAD file, program automatically starts a Setup Wizard, determines Drawing Extents and takes alignment polyline from the user designs horizontal and vertical curves with failure notifications according to project requirements. Finally results in an output that is a 3D final Digital Terrain Model files, along with several coordinates for final construction.
