This advanced option is system specific and is read from teklastructures.ini. It can also be set locally, see your environment ini file (env_<environment_name>.ini). Generally, there is no need to modify system-specific settings. Do not modify them if you are not an administrator.
Several system files are read from this folder, such as definitions for parametric profiles (.clb), IFC property set configurations (.xml), line type mappings (.lin), global UDA definitions (objects.inp), and access rights (privileges.inp).
The default location is XSDATADIR%\environments\common\inp\. You can use semicolon-separated lists of folder paths.
