Offset assembly feature lines

[areese9779]

Hello all,

I have reason stumbled across the offset assembly functionality of corridors, and for the most part, I have been quite impressed.  One thing that has come up that is odd to me that when I create a surface from the corridor using feature lines, the feature lines that are created by the offset assembly are not added to the corridor surface, even though they are visible and can be selected.  When I create the corridor using links, everything is fine and the surface looks great.  Has anyone else come across this or know of a possible solution?  I can work using the links, but the more curious part of my nature is a bit tortured not knowing why this is happening.

On a related note, does anyone have strong preferences/reasons for using links vs. feature lines, or vice versa?

I look forward to hearing what you all have to say!

Thanks,

Andy Reese

Does the resulting surface reflect the elevations of these feature lines or are they being ignored altogether?

[areese9779]

The feature lines are ignored altogether.  I have attached two screen captures of the surface contours that are generated along with the corridor and feature lines.  Corridor.png displays the surface built using feature lines (including all of the curb assembly feature lines) and corridor_top.png shows the surface that is created using the "Top" data link.

Any insights?

Hi Seth,

Did you by chance have a chance to look at this issue?  Were you able to reproduce the issue? 

Thanks,

Andy

I'm running into the exact same problem. Any workarounds or solutions yet?

Erik,

I haven't run into this - would it work if you added the link instead of the feature line? Also - check to see that your corridor baseline and your offset baseline are using similar station ranges. If you can't get it working, log it with me and I'll take a look at it.

Hey Jason,

They are using the same baseline stations. I can add the links and it generates surface data for the offset area, but my corridors are set up to work with feature lines. I've found it saves a lot of time to coordinate automated machine guidance work with C3D utilizing feature lines instead of link codes.

I'll submit a ticket on it,

Eric

Thanks Eric (sorry for the misspelling - you'd think I'd know how to spell your name by now!) I'll keep an eye out for the case and take a look at it when I get it. I'll go ahead and try to reproduce while I'm waiting.

[Jason.Hickey]

Just to update - I have tested this with my own data and can reproduce the issue easily. I will be logging this with our development team for review - in the meantime, the only workaround (not the best, I know) is to use links to build the surface rather than feature lines when using an offset assembly.

Hi Jason, Thank you for the follow up. I did want to pass on an additional solution for this issue that works well, which is to create feature lines that are dynamically linked to the corridor and then adding them to the corridor surface manually. It isn't ideal, but it works. Hopefully that can help folks while your folks look into the issue. Thanks again! Andy Reese

Was this issue addressed and fixed for 2013? I'm having the same problem with my offset assembly corridor. All feature lines past the first corridor region have a zero elevation when extracted or used for a surface, while the links produce a correct surface with the cross sections looking fine as well. Thanks.
