Display configura- Description tion not scaled for graphical 1-line; uses hidden lines and rise/drop symbology Additional notes Definition. You use Plan to display hidden lines for MEP objects. MEP Basic 2-Line Shows all pipe components and equipment as 2-line, regardless of system definition configurations for 1-line and graphical 1-line; hidden lines and rise/drop symbology not used Uses the 2 Line Display Representation While rise/drops are displayed in Basic 2-line, hidden lines are not calculated. This display is best suited when laying out designs if hidden lines are not needed and in Model views to accurately depict the 2 line representation of the objects. Mechanical Pipe By Size Shows all piping and equipment as 2-line, but can use system definition configuration to show 2-line, 1-line, or graphical 1-line, depending on size; uses hidden lines and rise/drop symbology Uses the Plan display representation for pipe objects and Plan Screened for other disciplines This allows all objects that are not pipe-related to be screened as background. MEP Schematic Shows all piping as 1-line, and shows all equipment as schematic symbols; uses hidden lines and rise/drop symbology; graphical 1-line unavailable in this configuration Mechanical Shows all piping and equipment as 2-line, but can use the system definition configuration to show 2-line, 1-line, or graphical 1-line, depending on size. Hidden lines and rise/drop symbology are used Uses Plan Display Rep for Mechanical and Plan Screened for non-Mechanical You can switch the current display configuration in a drawing for the desired 1-line or 2-line display. To use a combination of 1-line and 2-line displays based on nominal pipe size, use a system definition for the pipe system in conjunction with the appropriate display configuration for the drawing. RELATED For more information, see Display System Structure on page 135, Display Configurations on page 139, and Display Representations on page 137. 1-Line Display You use 1-line displays for annotation of construction documents. The fittings and connections in a 1-line pipe system display at their actual envelope dimensions. In-line and anchored components, such as valves, also appear as scaled 1-line. MvParts are displayed as scaled 2-line. In the following example, fittings, such as tees, elbows, and reducers, represent their actual envelope dimensions. A gate valve and a check valve also appear as scaled 1-line components. The pump displays as scaled 2-line. Pipe System Displays | 259
