Use this tab to view or change properties associated with this structure.
This tab displays the properties associated with this structure, along with their current values. Structure properties define a variety of characteristics of the structure object, including its basic size and shape and elevation adjustment behavior.
Some properties are specific to a certain type of structure. For example, only junction structures use rim and sump behavior properties. Only inlet-outlet structures use properties that define headwalls such as Headwall Base Width.
Some properties are read-only and others are editable. To change an editable property, double-click on the Value field and enter a new value, or select one from the list.
These properties specify general characteristics of the structure, such as the structure elevation at its insertion point, and the surface and alignment referenced.
Specifies the elevation at the structure’s insertion point.
Specifies the surface referenced by the structure.
Specifies the alignment referenced by the structure.
These properties specify characteristics such as the structure’s rotation angle, offset, station data, and the number of pipes that are currently connected to the structure.
Specifies the structure’s rotation angle.
Specifies the structure’s offset.
Specifies the structure’s northing.
Specifies the structure’s easting.
Specifies the number of pipes currently connected to the structure.
These properties are associated with junction structures only. They specify the structure’s rim elevation and adjustment behavior.
Specifies the current elevation of the structure rim. This cannot be edited if Automatic Surface Adjustment property is set to True.
Specifies whether or not to automatically adjust the rim elevation to the referenced surface, including the Surface Adjustment Value. When this property is set to True, grip editing the structure modifies the surface adjustment factor. When this property is set to False, grip editing the structure modifies the rim elevation.
If Automatic Surface Adjustment is set to True, the rim elevation is automatically adjusted by the surface elevation, plus the value specified here. If the structure is moved, resulting in the structure elevation changing, the structure automatically adjusts its elevation.
These properties are associated with junction structures only. They specify the structure’s behavior, elevation, and the depth of the structure’s sump.
Specifies the elevation of the structure’s sump, measured at the inside bottom of the structure. When this property is enabled, grip editing the structure modifies the sump elevation.
Specifies the depth of the sump area, measured from the inside bottom of the structure to the lowest pipe invert of all pipes connected to the structure. When this property is enabled, grip editing the structure modifies the sump depth.
Specifies if the sump depth is controlled by the depth based on the lowest pipe invert, or by a specific elevation value of the sump.
These properties specify a variety of part characteristics, such as part type, part subtype, and the part size name as defined in the part catalog. Some of these properties define the part’s basic shape and behavior, and therefore are read-only.
Specifies structure’s part type.
Specifies structure’s subtype.
Specifies structure’s description.
Specifies the part size name.
Specifies the basic primitive shape of the structure, as defined from the part catalog. For example, headwalls are typically defined in the part catalog as Bounding box shape, and manholes are typically defined as cylindrical shaped.
Specifies the clearance required from the top outside of the highest pipe connected to the structure, to the rim. This is defined in the catalog and ensure that pipes enter the structure at an appropriate elevation. For example, it prevents a pipe from entering through the cone of structure.
Specifies the distance between the sump to the structure’s rim. This property is for junction structures only.
Specifies the width of the base of the headwall. This property is for inlet-outlet structures only.
Specifies the thickness of the base of the headwall. This property is for inlet-outlet structures only.
Specifies the wall thickness for this structure, measured from the inside edge of the structure to the outside edge of the structure. This property is for junction structures only.
Specifies the thickness of the bottom of the structure. This property is for junction structures only.
Specifies the material defined for this part. This optional property is used mainly for labeling purposes. It allows you to identify the type of material used to construct this part.
This optional property specifies the model or type of frame used for a structure.
This optional property specifies the model or type of grate used for a structure intended to be used as a catchbasin.
This optional property specifies the model or type of cover used for a structure intended to be used as a manhole.
Specifies the height of the structure’s frame. This property is for junction structures only.
Specifies the diameter of the structure’s frame. This property is for junction structures only.
Specifies the length of the structure’s frame. This property is for junction structures only.
Specifies the width of the structure’s frame. This property is for junction structures only.
Specifies the height of the barrel section of the structure. This property is for two-tiered junction structures only.
This property lets you determine how close to the structure’s rim you can position a pipe. It is used for two-tiered junction structures only and specifies the clearance required above the top of the barrel section of the structure. It is similar to Vertical Pipe Clearance, but only describes the transition zone between the access cylinder and the larger barrel cylinder of a two-tiered structure.
Specifies the height of the cone shaped section of the structure. This property is for two-tiered junction structures only.
Specifies the thickness of the structure slab. This property is for junction structures only.
Specifies the inner diameter for this structure. This property is for junction structures only.
Specifies the total height for this structure, measured from the bottom outside edge of the structure to the top outside edge of the structure.
Specifies the diameter for this structure, measured from the outside edges of the structure. Circular shaped structures typically use the diameter property while non-circular structures use width and length.
Specifies the width for this structure, measured from the outside edges of the structure. Non-circular shaped structures typically use the width and length properties while circular structures use diameter.
Specifies the length for this structure, measured from the outside edges of the structure. Non-circular shaped structures typically use the width and length properties while circular structures use diameter.
These properties specify the hydraulic grade line, the energy grade line, and the junction loss values for pipe networks that contain this data.
Hydraulic grade lines and energy grade lines, when present, are displayed as a straight line through structures, connected between the HGL Up or EGL Up property from one pipe to the HGL Down or EGL Down property of the next pipe. For more information, see To Work With Hydraulic Property Data for Pipe Networks.
Specifies the elevation of the hydraulic grade line for pipe networks that contain this data.
Specifies the elevation of the energy grade line for pipe networks that contain this data.
Specifies the known capacity for pipe networks that contain this data.
Specifies the bypass target for pipe networks that contain this data.
