1. 只进行单位转换，保证实际长度一致.(When you just want to convert the Unit but keep the same length.)
a. Start->Program->Unigraphics V1x.0->UG Command Prompt b. Cd d:ugs150(eds140)ugii c. Ug_convert_part -in (-mm) name.prt 2. 进行单位转换，保证数值一致，实际长度放大或缩小.(When you make a mistake unit, So you want to convert the Unit but hope keep the same parameter value. )
a. 启动 UG, 打开UG part 文件，进入Modeling. b. Toolbox->Expression->export 产生 name.exp 文件. c. Start->Program->Unigraphics V1x.0->UG Command Prompt d. Cd d:ugs150(eds140)ugii e. Ug_convert_part -in (-mm) name.prt f. Close UG part 文件, 重新打开 UG part 文件。进入Modeling. g. Toolbox->Expression->Import with option(Replace Existing).
