In a day of a civil engineer, his project needs quick and accurate rebar drawings with dimensioning and quantity estimation. This need is now fulfilled by the revolutionary application that comes from the AEC application package. To meet the demands of value engineers regarding time, cost and effective, an automation manager like AEC 3D Rebar is needed. AEC 3D Rebar is a 3D modeling application and bar bending scheduler. From a given input 2D AutoCAD plans, the program AEC 3D Rebar automatically starts a Setup Wizard, determine Drawing Extents, draws Line Diagram, scales it, identifies columns, retain desired columns, sets columns grid, draws reference lines, footings, capitals, beam centre lines, wall centre lines, floor slabs, roofs, staircases and so on. Desired concrete elements are filled with reinforcement bars design requirements and per defined specifications.
