Construction Tab (Assembly Properties Dialog Box)

Use this tab to view the organizational structure of the subassemblies and subassembly groups comprising the assembly.

Assembly Type

Specifies the roadway or railway type that the assembly supports. When the assembly is used in a corridor that uses either cant or superelevation axis of rotation, the Assembly Type must match the type that is specified when cant or superelevation is calculated for the alignment.

Item

The left pane tree view displays the organizational structure of the assembly. Subassemblies are displayed in the tree view in the order in which they are processed (top to bottom). This is the same order in which each subassembly was added to the assembly. The tree view also shows how the subassembly groups are connected to a primary baseline, or to a given offset line. You can delete, move or rename many items in this view using the right-click context menu.

Input Value

When a subassembly is selected in the left pane, this pane lists information on the input parameter values that are used to calculate the size, shape, and geometry of the subassembly.

Value Name

Specifies the name of each input parameter associated with the subassembly.

Default Input Value

Specifies the input parameter value used in the processing for the selected subassembly. To edit this field, double-click in it.

Parameter Reference

Specifies that the output value from another subassembly is used as the input parameter value for the selected subassembly.

• Use: The value specified in the Get Value From field is used for the input parameter value instead of the default input parameter value.
• Get Value From: Specifies the output value from another subassembly that is used as the input parameter value for the selected subassembly.

Output Value

Lists read-only information about any output parameter values used during processing for the selected subassembly. These output values can be used as input values for other subassemblies. The actual output values are calculated only when the assembly is applied (when the corridor is created).

Value Name

Specifies the name of any output parameters for the selected subassembly.

Output Value

Specifies the value of any output parameters for the selected subassembly.

Subassembly Help

When a subassembly is selected in the tree view, click this button to display the Help topic describing the construction, behavior, and other details of the subassembly.
