New features in StormCAD V8i INTEROPERABILITY Common file format with other Bentley sewer and stormwater products: With StormCAD, CivilStorm, SewerGEMS, and SewerCAD's new unified file format, the .stws file replaces the .stc, .csd, .swg, and .swc files. This common file format makes modeling teams’ workflows more efficient, since a model created in any one of these products can now be seamlessly opened and edited in another. Updated support for MicroStation: You can run StormCAD from within MicroStation V8i (SELECTseries 3). A MicroStation license is required – if you don't have a MicroStation license, you can choose to run StormCAD in its stand-alone mode. Updated support for AutoCAD: You can run StormCAD from within AutoCAD 2014 (32- and 64-bit). An AutoCAD license is required – if you don't have an AutoCAD license, you can choose to run StormCAD in its stand-alone mode. i-models publishing: StormCAD can now publish i-models (containers for the open exchange of infrastructure information) in 2D or 3D.
