Edit a Vertical Alignment
Edit a vertical alignment (VAL) by adding, removing, inserting, and modifying curves at Points of Vertical Intersection (PVIs). You can create one or more VALs for each horizontal alignment (HAL) in your project.
Note: You can only edit one alignment at a time. If you have multiple alignments selected, only the active alignment (indicated in bold in the Project Explorer) appears in the Alignment Editor.
Prerequisites:
- License; See the Subscription Plans page. For a license matrix by command, see the License page in the TBC Community. Also see View and manage licensed features.
- Alignment
To access these options:
- If you have just created an alignment, skip to one of the operations below. Otherwise, select an alignment and do one of the following:
- Select Create Alignment in Corridors > Alignment.
- Pick an alignment in a graphic view, right-click and select Edit from the context menu.
- Select an alignment in the Project Explorer, right-click and select Edit from the context menu.
The Alignment Editor displays.
- Click the Vertical tab.
To add a vertical curve at a PVI:
- Select a curve type in the PI Type list. The type you select determines which values you can enter in the other cells of the row. For descriptions of the options, see Vertical Alignment Options.
- Press or to advance to the next cell.
- Enter values in each of the available cells (based on the type of curve you chose) as specified in the engineering design.
Note: When entering values, you can always right-click in the Profile View for COGO and snap options.
Note: If your engineering design shows values in a format different that the Alignment Editor is using, click the Project Settings icon to access the Project Settings dialog where you can change the display formats and entry methods. - Repeat the previous steps until you have created PVIs for the entire VAL.
Note: Visually check the vertical alignment in the Profile View as you enter values.
To edit an existing curve at a PVI:
- To change a PVI type, click a cell in the PI Type column and select a new type from the list.
- To change a value, click in a cell and specify a new value. The alignment updates in the Profile View as you make changes.
- To Undo, Cut, Copy, Paste, and Delete values, click in the cell, then right-click and select an option from the context menu.
- To access Insert Row, Delete Row, Copy, Alignment Project Settings, and Float View commands, click at the beginning of a row, then right-click and select an option from the context menu.
