Offset Parameters Tab (Profile Properties Dialog Box)

This tab is available for dynamic offset profiles that are created during the process of creating alignment offsets or junctions.

Note: To switch an offset profile between dynamic and static states, use the Profile Data tab. If an offset profile is static, then the Offset Parameters tab is not displayed for that profile. However, any crossfall regions you may have created when the offset profile was dynamic are preserved.

Crossfall Regions

Specifies the chainages along the parent alignment to which to apply specified crossfalls to the offset profile.

The crossfall value that was assigned when the offset profile was created is shown in the first row. This row cannot be deleted, but you can edit the value by clicking in the Value field.

When you click this button the dialog box is temporarily dismissed and you are prompted to select a chainage along the parent alignment baseline.

You can continue to select new chainages and define crossfalls, or press Enter to complete the selection and redisplay the Profile Properties dialog box.

Deletes the selected crossfall regions. The first region, which starts at the beginning chainage of the profile, cannot be deleted.
