Category in Advanced options dialog: Model views
Set this advanced option to TRUE to bypass your graphic
adapter in model views. Use this advanced option if you have problems with your
display (for example, lines are not drawn correctly). The default value is
FALSE.
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.
