To Edit Corridor Region Assembly Offsets

If a region has an assembly offset specified, you can edit the horizontal and vertical baselines and chainage start and end for the offset.

1. In the drawing, click the corridor, then right-click and click Corridor Properties.
2. In the Corridor Properties dialog box, click the Parameters tab.
3. To change the horizontal baseline for the offset, click the Horizontal Baseline field. Select the horizontal baseline in the Select a Horizontal Baseline dialog box.
4. To change the vertical baseline for the offset, click the Vertical Baseline field. Select the vertical baseline in the dialog box that is displayed. Depending on what you select for the horizontal baseline, this may be either the Select a Profile dialog box or the Select a Vertical Baseline dialog box.
   Note: For offset baselines, the vertical baseline can be comprised of a different alignment/profile or feature line than what is specified for the horizontal baseline.
5. To change either the start or end chainage for the region, select either the Start Chainage or End Chainage field. Enter the chainage number or click and select the chainage in the drawing.
6. Click Apply.
