Generate No Impact

You can avoid making impacts on vertical alignment geometries.

  1. From the Road and Railway sections of the action bar, click Horizontal Alignment .
  2. Edit the horizontal alignment geometries.
  3. From the Alignment assistant, click Preferences .
    The Impact mode in vertical alignment pane appears.
  4. Click No impact.
  5. To switch to the vertical alignment, click Vertical Alignment from the Alignment assistant.
    The vertical alignment appears.

The modification of horizontal alignment geometries has no impact on vertical alignment geometries.

Delete All Impact

You can delete all impacted geometries and modify the position of non-impacted geometries in vertical alignment.

  1. From the Road and Railway sections of the action bar, click Horizontal Alignment .
  2. Edit the horizontal alignment geometries.
  3. From the Alignment assistant, click Preferences .
    The Impact mode in vertical alignment pane appears.
  4. Click Delete all.
  5. To switch to the vertical alignment, click Vertical Alignment from the Alignment assistant.
    The vertical alignment appears. The impacted geometries are deleted.
  6. Edit the position of non-impacted geometries.

Fix Impact Manually

You can convert all the impacted geometries into construction elements to manually edit them and modify the position of non-impacted geometries in vertical alignment.

  1. From the Road and Railway sections of the action bar, click Horizontal Alignment .
  2. Edit the horizontal alignment geometries.
  3. From the Alignment assistant, click Preferences .
    The Impact mode in vertical alignment pane appears.
  4. Click Manual fix.
  5. To switch to the vertical alignment, click Vertical Alignment from the Alignment assistant.
    The vertical alignment appears. The impacted geometries appear as dashed red construction geometries.
  6. Select the impacted geometries you want to fix.
    A context toolbar appears.
  7. To fix the impacted geometries manually, click one of the following:
    OptionDescription
    to keep the selected impacted geometry
    to delete the selected impacted geometry
    to keep all impacted geometries
    to delete all impacted geometries

    The Delete All/Keep All commands apply only to areas. When two areas are impacted in the vertical alignment, and you run one of the two commands, only the selected area is impacted by the changes, and not all the geometries in the vertical alignment.

  8. Edit the position of non-impacted geometries.
