Delete an alignment from either the drawing window or the Toolspace Prospector tab.
When you delete an alignment entity, the Tangency Constraint of adjacent entities automatically changes as necessary.
For example, if you have a free curve between two fixed lines, and you delete the second line, then the curve will be changed to Constrained By Previous (Floating). This happens because a free entity can exist only between two fixed entities.
To delete an alignment from the drawing window
When you delete an alignment from the drawing window, the dependent objects will also be deleted. If you select the alignment in the drawing window and press Delete, the corridor and profile are cleared from the drawing window. The profile is also deleted from Prospector because it is a child of the alignment object. The corridor object is still present in Prospector because the alignment was only one of the objects from which it was created. You can add another alignment to the corridor as a baseline, and then rebuild the corridor.
- Select an alignment in the drawing.
- Press Delete.
