The IDF file extension is associated with Autodesk Civil 3D. An IDF file stores intensity-duration-frequency factors, which describe rainfall intensity for different storm durations and frequency or return-period conditions.
The file uses ASCII text. Civil 3D uses these factors as rainfall information for relevant hydrologic and stormwater design workflows. The format is a supporting data format for Civil 3D rather than a general-purpose CAD drawing format.
Open the file through the Autodesk Civil 3D workflow that uses intensity-duration-frequency rainfall data. Civil 3D is the appropriate program for interpreting the file; a text editor can display its ASCII contents but will not provide the associated engineering functions.
