Corridor, Offset Assembly, & Featurelines

[Jeff_M]

I could've sworn this worked correctly at one time, but I sure canot get it to do so now. I have a small roadway widening which includes a parking bay and a sidewalk that varies in location, elevation, & width. Here are the 3 subassemblies used to create the corridor. The top is the normal half section (we are widening just the left side of the road), the center one is for the elevated sidewalk, and the lower one is for the parking bay region so it includes an Offset Assembly.

Everything works as desired, with the lone exception of the lack of featurelines being created for the Offset Assembly objects. All the curb & sidewalk f/l's are fine for the other regions using the 2 other assemblies, but I get none with the Offset Assy. Is this normal and my memory has failed me once again? Or should this be working and I've somehow mucked it up?

Please don't get offended but is there a chance that it is there but is turned off somewhere?

Thanks for looking, no offense taken. I'm looking for any suggestions that might help. I don't think they are off, as they are defined to use the same style as those that are showing and the curb/sidewalk subassemblies are identical (code-wise).

Looked at you picture again and saw you red feature lines on the plan view then looked at your subassemblies, I noticed on the first two there is a red dot in the upper left corner of each sidewalk? but then on you third assembly that red dot is gone on the same corner. Does that red dot mean anything on the other two subassemblies? I looked for another red dot on the corner of the inner shoulder/pavement and noticed one on the first subassembly but not on the second but not sure what exactly which subassembly is being projected on the plan view. I will look harder at your picture and let you know if I see something else.

Can you attach the file?

I have found the same behavior with offset assemblies in versions up to 2011.  (Have not tried this yet in 2012).   This becomes a problem when building corridor surfaces from feature lines.  You have to build the surface from links.

Because of this, I rarely use offset assemblies.  I will model the offset with a generic offset and elevation link, with the omit property set to 'yes'.  It will create all links radial to the the baseline alignment, so you wont get the curb and sidewalk perpendicular to the edge of pavement or flowline.

Sure thing, Matt. This is reduced down as far as I think I can go and still leave the required details showing the problem.

C3D2012 by the way.

That's messed up. I created a new dwg, made a new alignment, profile, corridor, offset etc.  It worked perfectly.  I XML'd your stuff into mine and it did not work.

Ah ha! So it IS supposed to work! Thanks for checking and letting me know at least my memory is still intact. Now to figure out why it isn't....
