Use the Alignment Entities vista and Alignment Layout Parameters dialog box to display and edit parameters of alignment entities that are part of the solved alignment geometry.
The Alignment Entities vista displays a form that is like a spread sheet, where each row represents an alignment entity and each column represents a parameter. You can right-click a column heading to display options for customizing the display of detail in the column views.
You can use the alignment grid view, which is also known as the Alignment Entities vista, to quickly scroll through all the sub-entities that make up the alignment. You can select a sub-entity in the Alignment Entities vista, and then edit it in the Alignment Layout Parameters dialog box. Attributes in the Alignment Entities vista and Alignment Layout Parameters window are automatically updated as the alignment is edited.
You can use the Alignment Layout Parameters dialog box to display and edit the many attributes for a single alignment sub-entity. The parameters that are displayed are dependent upon the constraints you used to create the entity.
The Alignment Layout Parameters dialog box contains up to three panels. The Layout Parameters panel, which displays the geometric parameters of the selected sub-entity, is always present. In this panel, the Value column lists the actual value of each sub-entity Parameter. If the alignment was created using the criteria-based design feature, the Constraint column lists the value to which a Parameter is constrained by the specified design criteria. Use the Value and Constraint columns together to view whether the sub-entity parameters meet the specified design criteria. If the alignment was not created using the criteria-based design feature, the Constraint column is not available.
Two additional panels may be present on the Alignment Layout Parameters dialog box if the alignment has design criteria applied to it. If the alignment has a design criteria file associated with it, the criteria from the file are displayed in the Design Criteria panel. If the alignment has a design check set associated with it, the name and contents of the design check set are displayed in the Design Checks panel.
If any of the parameters violate either a design check or the standards specified in the design criteria file, a 
warning symbol appears next to the violation. For more information, see Viewing and Correcting Alignment Design Criteria Violations.
The attributes of a curve or other alignment entity that you can edit depends on the method you used to create the entity. Generally speaking, you can edit the numeric value of a parameter if the parameter was used to define the entity. For all other parameters, numeric values are calculated and displayed but cannot be edited.
