C3D 2016 Corridor Snap Issue

[Cadguru42]

I think I found a bug. I've got a corridor drawing where the shrink wrap boundary doesn't work correctly, so I am manually drawing a polyline that'll be my corridor surface boundary. To do this, I'm snapping to the last link on the outside of my corridor. This works fine and I've been doing it for years (when the automatic boundary doesn't work), except where an offset assembly was used. Any subassemblies that are attached to an offset alignment I can't snap to in the plan view.

At first I thought it might be due to a single subassembly, but I tried in other parts of the corridor with an offset assembly that has an OOTB subassembly and the same thing happens. It's always the far outside subassembly that's attached to an offset assembly that this happens with. 

Here's a screencast that shows how snapping won't work on a subassembly that's the last one on an offset assembly.

Hi!

A curiosity: If you do a  "Force rebuild corridor" , does work?

No. No matter how much the corridor is rebuilt or what subassemblies, baselines, or assemblies are used the far out-side subassembly that's attached to an offset assembly will not let me snap to it.

Maybe this is just for Autocad but try:

Under Options -> Drafting (TAB) -> AutoSnap Settings:  The top three boxes were unchecked Marker, Magnet and Display AutoSnap Tooltip

From autodesk:

You are not able to snap to an xreferenced corridor objects in Civil3D 2016. This is a known issue reported to the development from version 2010 onwards.
 

Solution:The workaround is to perform the followings:

1. Create a surface from the corridor
2. Xref the corridor along with the surface

This is not an XREF. I am trying to snap to the corridor itself in the drawing that the corridor is created in. 

As for Auto Snap, if you look at the screencast you can see that the running snaps are working for one side, but not the other. Even when I type END to force it to snap to the end it refuses to snap to the subassemblies on the outside of an offset assembly, but does snap to the opposite side (same subassembly, too).

Then I have no suggestions. Think you have a bug like you are suggesting. Good luck solving the issue!

Be sure to send Autodesk a message about this.
