Customizing System Types

Customize the type parameters for a system type, including graphical overrides, materials, calculations, abbreviation, and rise/drop symbols. You can customize parameters for the default system types (supply, return, and exhaust air), as well as any new system types you create.

Edit graphical overrides

You can customize graphical overrides to control the color, line weight, and line pattern for the collection of objects assigned to a system of that type. The graphical overrides apply to the project, and are not view-specific like filters.

1. Right-click a system type, and click Type Properties.
2. In the Type Properties dialog, under Graphics, for Graphic Overrides, click Edit.
3. In the Line Graphics dialog, for Lines, specify Weight, Color, or Pattern. Click OK.

Graphical overrides for a system are prioritized between Phasing and Filters. Weight, color, and line pattern per system type will override the settings per category. However, a view filter always takes precedence over the settings in the system graphical overrides.

The table below summarizes the prioritization for graphical overrides.
