The Object Styles tool specifies line weights, line colors, line patterns, and materials for different categories and subcategories of model objects, annotation objects, and imported objects in a project.
You can override project object styles on a view-by-view basis. For more information, see GUID-62EE20DA-E773-4049-B90C-38EAC5FE1814.htm#WS46B90C3CB2C58CAD922804FC7FA4315F-7F7D.
