HydroCAD is CAD and CAM software for Microsoft Windows used for stormwater drainage design and hydrologic and hydraulic modeling. The hcc file extension is associated with its storage chamber definitions.
An hcc file stores the parameters that define a storage chamber. The file uses plain ASCII text and is intended for use within HydroCAD rather than as a general-purpose CAD interchange format.
Open an hcc file with HydroCAD on Microsoft Windows. The file is intended to be loaded or used by HydroCAD as part of its storage chamber data.
Because the file uses plain ASCII text, it can also be viewed in a text editor, but a text editor may not correctly interpret or validate the chamber definition.
Use HydroCAD to work with the storage chamber definition. HydroCAD may be able to export *.hcc files to other formats.
