Use this vista to view and edit entities that are part of the solved alignment geometry.
Use the Alignment Entities window to navigate through all solved alignment entities. You can select an entity in the Alignment Entities window and then edit it in the Alignment Layout Parameters window. Attributes in the Alignment Entities window are automatically updated as you edit the alignment.
You can filter the display to show a selected range of entities along an alignment. See Selecting Alignment Entities for more information.
The Alignment Entities vista is like a spreadsheet. Each row represents an alignment entity and each column represents an attribute for that entity. You can resize, move, and copy columns.
The first column (No.) is always displayed. It does not move when you use the scroll bar.
This window remains open when you grip edit the alignment or enter another command. The window closes when you either delete the currently selected alignment, click the X button, or click 
on the Alignment Layout Toolbar.
- No.
-
Specifies the entity number in the order of selection. This variable changes as entities are selected and deselected.
A
warning symbol is displayed in this cell if the sub-entity violates the specified design criteria. - Number
- Type
- Tangency Constraint
- Parameter Constraint Lock
-
Specifies whether the parameters associated with the Parameter Constraint property may be edited.
(Locked): Only the parameters permitted by the Parameter Constraint property are enabled for editing.
(Unlocked): All parameters (with some exceptions) are enabled for editing.
If the Lock All Parameter Constraints option on the Constraint Editing Tab (Alignment Properties Dialog Box) is selected, then all entities will be set to locked.
- Parameter Constraint
-
Specifies the number of points in the constraint of the tangent.
If the entity was created by best fit, [...] appears to the right of the Best Fit entry. If the entity has been edited since it was created from best fit regression data,
appears. Click [...] to open the Regression Data vista and review the regression points and synchronize the entity to the regression data. - Length

A
warning symbol is displayed in this cell if the sub-entity length value is not greater than or equal to the value in the Minimum Length cell. - Attainment Method
-
Specifies the superelevation attainment method for each sub-entity. The Attainment Method is defined in the design criteria file .
