XS_DEFAULT_BREP_PATH
Use to define the location of the default shapes that are available in the shape catalog when you create a new model. By default, this advanced option is set to point to the common environment, and the definition files of the default shapes are read from the \Shapes and \ShapeGeometries folders under the \profil folder.
The definition files of the shapes that you use from this location when you create items in a model are copied to the model folder.
Example
To have Tekla Structures read the default shapes from the German environment, set this advanced option as follows:
set
XS_DEFAULT_BREP_PATH=%XSDATADIR%\environments\germany\
or
set
XS_DEFAULT_BREP_PATH=C:\ProgramData\Trimble\Tekla
Structures\<version>\environments\germany\
