- 3 minute read
The left hand side of the window displays the list of available trunnion support types (TT series). Filter criteria can be used to specify which trunnion support types are displayed in the list.
When a trunnion is highlighted, the support standard Name, Replacement Name and Description appear at the top of the window. The information is outside of the tabbed areas and displays on all tabs.
The plotfile for the selected trunnion displays on the right hand side of the window. To zoom in to an area of the plotfile, click and drag the middle mouse button to create a zoom area. To restore the original size, right-click and select Reset Limits from the drop-down menu.
Click Apply before selecting another trunnion type, otherwise any changes are lost.
Support Standard
The trunnion name selected in the list of available trunnion support types displays, and cannot be changed. The support standard is the code used internally within the software by the Supports application
Standard Replacement Name
The Standard Replacement Name is used on all windows in the supports application when referring to the support type defined by the support standard. It is also output in place of the support standard name on automatic drawing production drawings. The name can be modified by editing the text in the field.
Description
The text in this field is configurable to suit each design project, and only displays in the Model module during the creation of supports. The description in the field does not affect any associated Material Take Off (MTO) details output in automatic drawing production, as the details are stored in the catalogue database.
Active
Allows you to specify which of the available trunnion types are available for use in the project by the user.
Select the check box to include the currently selected trunnion in selection lists.
Deselect the check box to exclude the currently selected trunnion from selection lists.
The Active setting overrides any subsequent active setting that displays on the Active/Shop Flag tab. Refer to Active/Shop Flag Tab for further information.
Vendor Reference
Not available at this release.
Elevation Restriction
Specifies the elevation (height) at which a trunnion can be created at and above. For example, setting a value of 5000 means the trunnion can be created at any elevation at 5000mm and above. If a value of -1000 is input, the trunnion can be created at any elevation below 1000mm.
The default setting is *, indicating that there is no restriction on the elevation at which the trunnion can be created.
Pipe Specification Material Code
The pipe material is specified here:
-
CS Carbon Steel
-
SS Stainless Steel
-
FG Fibre Glass
-
GV Galvanised
-
PL Plastic
-
CN Cupro Nickel
-
ALL represents ANY material, for example, valid for all pipe specifications.
For example, the text value CS represents the setting stored at a valid PIPE specification, at the uda :MDSPipeMat, for use by the Supports application. These settings are configurable and not restricted to the example display values.
SKey
The symbol key that is stored against the SDTE of the specification is displayed here. A symbol key specifies a symbol representation for a support type on an isometric drawing.
SKey Override
You can override the symbol key that is stored against the SDTE of the specification. Input an alternative symbol key value in the field to modify the symbol representation for a support type on an isometric drawing.
Support Function
The trunnion support function is specified here. For example, TT for a Trunnion.
By default, ancillary, hanger and trunnion standards are assigned a default support function corresponding to their standard code. For example, AT, AN, FH, VH, TT, these are fully configurable.
To specify a support function for an ancillary, refer to Ancillary Data for further information.
To specify a support function for a hanger, refer to Hanger Data for further information.
Isometric MTOC Flag
Determines if the material for the trunnion appears in the material list on the piping isometric.
Select the check box to include the material in the isometric material list.
Deselect the check box to exclude the material from the isometric material list.
The isometric MTOC flag overrides any subsequent shop flag settings that display on the Active/Shop Flag tab. Refer to Active/Shop Flag Tab for further information.
