InfoDrainage for Civil 3D software is a tool designed to support the requirements of delivering BIM (Building Information Modeling) compliance with optimized drainage design workflows. Civil 3D pipe networks and surfaces can be created from InfoDrainage networks or vice-versa and kept up to date via Parts Mapping. With InfoDrainage providing the tools to design, optimize, analyze, and compare drainage designs, gaining approval can be easy. Including traditional drainage and green infrastructure elements as 3D objects, the design remains true to site, helping to better communicate and support sustainable design approaches. Drainage designs involve iterative changes, which can be a painful and time-consuming process. Round-tripping is supported from InfoDrainage to Civil 3D networks, which can help to reduce data errors during required model updates. Using InfoDrainage for Civil 3D, engineers can efficiently represent their designs, giving greater confidence in the validity and accuracy of design information.
