Road Target Issue

Hi,

Issue with a U Shaped road and targeting.

Assembly and corridor created and then corridor surface but as you can see, the corridor takes in all the lands between the road? Obviously a targetting issue, well I assume so anyway.

What am I missing.

Thanks in advance.

Try adding the Corridor Boundary:

See the help article at To Add Corridor Surface Boundaries

Hi @rdavisMX6RG

As @ChrisRS said, you have to create boundary to your corridor.

In the properties window of your corridor, go to Boundaries tab, right click on your surface and try first "corridor extents as outer boundary". If it will not work, for sure one or both of other two (interactively and polygon) will work.

You can share your file to take a look.

Regards

If you have a shrinkwrap corridor surface boundary set and it isn't working, the issue could be some bowties somewhere in the corridor. Fixing those usually gets my shrinkwraps to work.

Hi @rdavisMX6RG, is your problem related to a ConditionalHorizontalTarget? If so, reduce the MaxumumDistance to the lowest value possible that can still be read by the subassembly

Another option is to split the targeted element (say polyline, feature line...) in the middle and assign the two resulting elements as independent targets. When assigning more than one target on the same side, activate the box, target to nearest.

Or, Split your corridor in the middle and assign targets independently.

Best regards!
