Corridor items feature definition set

Description

This is a custom interactive tool for setting feature definition to an alignment.
The user is prompted to select a horizontal alignment and feature definition name . The selected feature definition is then applied to an alignment.
The CorridorItemsCorridorCreator class extends DgnElementSetTool which handles different events to interact with UI, the CorridorItemsCorridorCreator class overrides the events here in this tool .

Remarks

This sample code is a part of ManagedSDKExample which you get with SDK installation under "examples" section in SDK installation directory.
If you encounter any error while using DgnElementSetTool class, make sure to add a reference to Bentley.DgnDisplayNet.dll by selecting Project > Add Reference or change the projects .csproj file to add reference to this dll .
The default dll location will be "C:\Program Files\Bentley\OpenRoads Designer CE 10.11\OpenRoadsDesigner\Bentley.DgnDisplayNet.dll".
The method OnDataButton() handles the horizontal alignment selection from User interface.
