UNV

Menu: Files->Import→UNV...

With this option it is possible to read I-DEAS UNV format, usually with extension .unv or .uff.

This importer is implemented as a pure Tcl plugin, with limited features (only some UNV entities are supported)
It converts the UNV information into a preprocess mesh of bars, and an auxiliary post.res file with the structural modal analysis results for postprocess (natural vibration modes)
