Elevation Control
On the Elevation Control tab of the Sidewall to Solid form, you can override the settings on the Profile tab to control the roof and floor position of the generated solid.
Select Use Elevation Control and then nominate the files that contain the roof and floor points. At any location along the tunnel or drive there should only be one roof (or floor) point. These points are used to calculate the height of the tunnel or drive. They are not used to define the shape of the profile.
Note that choosing this option will disable the Height (H) parameter on the Profile Shape tab.
Floor points (override sidewall Z field)

If required, define a filter to selectively control the records to be processed.
