Renovation styles control design rules for Existing, Demolished, and New categories by object type. In the Renovation Options dialog box, Renovation styles can be imported from external catalogs, exported to external catalogs, modified, saved, or deleted. Renovation styles for display and layer assignment can be specified independently from each other for maximum flexibility. These settings are saved to the current drawing.
The design rules control how objects display, how layer assignments are made, how Renovation styles and blocks are named, and whether the same material definitions display regardless of whether objects are viewed in a plan view or in a 2D section or elevation view.
