XS_DUPLICATE_CHECK_LIMIT_FOR_COPY_AND_MOVE
Category in Advanced options dialog: Modeling properties
Use this advanced option to define the maximum number of objects that are checked for duplicates while copying or moving objects.
If the selection contains too many objects, Tekla Structures does not check for duplicates. Enter an integer value. The default value is 100.
This advanced option is user specific and the setting is saved in options.bin under the user folder, for example, in C:\Users\<user>\AppData\Local\Trimble\Tekla Structures\<version>\UserSettings. Restart Tekla Structures to activate the new value.
