Hide or show corridor regions or entire baselines.
It is recommended that you hide unneeded regions while performing corridor edits.
For example, when editing a corridor that contains multiple regions, hide the regions that you are not editing. This typically results in faster system response time while editing a corridor.
This command restores the visibility of any regions whose visibility is currently turned off. The command is not available if all regions are visible.
To hide corridor regions or baselines using the ribbon
- In the drawing, click the corridor.
- Click Corridor tab
Modify Region panel

Hide Regions
. - Select the regions to hide.
- When you are finished selecting regions, press Enter.
You can also hide regions or baselines using the Parameters tab of the Corridor Properties dialog box by clearing the check box next to the region or baseline name. The check boxes you use to hide a region have a tri-state display. If a baseline has multiple regions and only one of the regions is selected, the check box is dimmed and not available.
