Category in Advanced options dialog box

Model View

Defines whether parts that do not belong to assemblies and cast units are shown or hidden in assembly and cast unit views. The default value TRUE hides the parts that do not belong to the selected assembly or cast unit. If you set this advanced option to FALSE, the parts are not hidden.

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.
