matlab读取uff文件数据 Universal file generation from I-Deas for Test can be split into two categories: export of model file data and export of adf data. It is not possible to write both sets of data to a single file. Written with a model file universal file are the geometry, elements and traceline data. However, just to add confusion, nodes and tracelines can also be written separately in their own file format.(Universal file generation from I-Deas for Test can be split into two categories: export of model file data and export of adf data.
