The reason for the problem is: when importing IGS file, the prompt: converter image not found. The environment variable IGES_DIR may be set incorrectly. (This is also the prompt when exporting IGS files) As shown in the following figure:

Problem analysis: when this problem occurs, let's first analyze whether the environment variable IGES_DIR may be set incorrectly, and the system prompt is not wrong, because when the system can't find the IGES conversion tool in the program directory, it will prompt you whether you have set the path of the IGES converter yourself. Of course, almost no one will set such an environment variable, because it is meaningless, so now the system can't find this small data conversion tool inside the UG program. z: A" F& R( l- M6 w2 n

When opening its UG program directory, it was found that the IGES folder was missing, so UG issued a warning that the IGES conversion tool was not found: 2 X. O/ ]5 m( S+ Y- C

The normal UG program directory contains the folder IGES, which contains the IGES data conversion tool, as shown below: .u2j.b)) `1x! z; y

1, reinstall UG software, and choose complete installation in installation mode, not customized installation.

2. If you don't want to reinstall, you can copy the IGES folder with the same version number to someone else and copy it to your UG program directory, which is the location shown in the above picture. * u2 o5 S+ V 1 }% V? J5 `+ M+ e
