Bend_Angle The bend angle is defined at placement for a component that has a variable sweep angle.
Bend_Radius The bend radius is defined through the component itself by means of a table lookup.
Bend_Radius_NPD The bend radius in terms of NPD from the PCD file for the bend component.
Body_OD_n (n = 1-5) The body outside diameter is the outer diameter of either a bolted, male, or female end of the indicated termination type.
BOLT_DIAMETER BOLT_EXTENSION
Diameter information not used when placing a flanged
component. Table lookups are performed during the execution of the MTO process when two mating flanges are found. These keywords are used to hold the data retrieved for the table and then pass on to the MTO process.
Br_Ref_Thick The branch reinforcement thickness. Br_Ref_Width The branch reinforcement width. Branch_Angle Used for a table name lookup.
Branch_Table Identifies the branch insertion table used to determine the name of the branch commodity item to be used for tee and lateral branches.
Commodity_Code A user-assigned code that together with the NPD and schedule/thickness uniquely defines the component.
CP_Offset_n (n = 1-5) The connect point offset adjusts the graphics relative to the connect point (for flanges, it adjusts for the gaskets) for female, adjust for penetration. Male is set to zero.
CP_Normal_n (n = 1-5) The normal vector.
CP_Primary_n (n = 1-5) The flow centerline vector. CP_Secondary_n (n = 1-5) The secondary vector. CP_to_Origin_n (n = 1-5) The CP to origin dimension.
Depth_n (n = 1-4) The connect point depth is the depth of a socket as defined in the table FEM_Term_Rat_TS. It determines a component's dimensional parameters by calculating the depth of the socket minus 1/16 inches.
DIM_TOLERANCE = 1/64 in.
The minimum dimension standards are the minimal values permitted in the Eden program. The minimum distance used for checking connect point separation if 400 units of resolution (USRs), which is approximately equal to 1/5 inch.
Dry_COG The center of gravity dry. Dry_Weight The dry weight.

Facing_OD_n (n = 1-5) The facing outside diameter is the outer diameter ofeither a bolted, male, or female end of the indicated termination type.
F_to_C_Dim_n F_to_F_Dim
(n = 1-5) The face-to-center and face-to-face dimensions retrieve information from a dimension table and pass that information to the database for the appropriate connect point or face to face dimension.
Gasket_Sep_n (n = 1-5) The gasket separation.
Gen_Flag_Red Gen_Flag_Green
The generic flag retrieves the table suffix for use with table identification.
Geo_Ind_Std The geometric industry standard is used to define table lengths. The data comes from the piping component data entry.
Insulation The insulation thickness is defined by the designer at time of pipeline placement. It is used to increase the volume of the interference detection and the display of the Insulation Graphics. Insulation_n (n=1 to 4) This variable is used to exclude insulation by connect
point.
Item_Name This variable equates to the model code used in defining a table name.
MIN_CYL_DIA = 1/32 in.
The minimum cylinder diameter permitted in the Eden program.
MIN_DIMENSION = 5/8 in.
Hard-coded global variable. The minimum linear dimension value permitted by the Eden program is approximately 1/16 inch.
Min_Weld_Size The minimum weld size retrieves output from the Branch_Angle/Branch_Table.
Nipple_Length The nipple length is retrieved from the modifier column in piping component data from the reference database.

Nom_Bend_Rad The nominal bend radius. This variable will write to the database and allow reconstruction of the component.
NUMBER_BOLTS Table lookups are performed during the execution of the MTO process when two mating flanges are found. This keyword is used to hold the data retrieved for the table and then pass on to the MTO process.
Number_Miter The number of miter joints is the number of miters to be used in a mitered joint. It is retrieved from the modifier column in the piping component data from the reference database.
Number_of_Taps The number of taps is retrieved from the modifier column in the piping component data from the reference database.
