Autodesk InfoDrainage 2026.2 Update
InfoDrainage is an automated stormwater design software program that provides comprehensive assessment of stormwater designs.
InfoDrainage 2026.2 Update enhances the level of detail available in drainage designs by reading additional pipe attributes from your pipe catalogues, including material type and wall thickness where available. The software also introduces suggested trench width calculations and allows you to specify bedding and backfill materials, supporting more accurate and comprehensive detailed design outputs.
