You can add non-standardized display settings from the current project drawing to the project standards. You can do this, for example, if you have created a complex display configuration in a project drawing and want to include that into your standards.
After copying a display setting to the project standards, you need to synchronize the project to use the new standard setting.
The new setting is listed in the lower panel, which lists styles and display settings in the project drawing that do not exist in the project standards.
In this case, the non-standardized display setting remains in the project drawing, and is not entered in the standards.
In this case, the non-standardized display setting will not be listed again in future updates, except if you select Show objects set to ignore during project standards synchronization or remove the Ignore flag from the display setting in Display Manager.
