corruption of the surface when I delete a featureline

[dan]

I am doing a grading design using feature lines.  After many hours of successfully working on this design, all of a sudden when I delete a feature line, my dtm (surface) is corrupted.  It seems as though the some of the points along other feature lines have been randomly changed.  If I go through and change the elevations of these other (corrupted) feature lines - they wil stay as corrected until I again delete a featureline.

Does anyone have an idea of what is wrong.

Sounds like you do not have your feature lines organized on sites.  If your feature lines are all on the same site, then they will all interact with each other.

Also, are you using 2016 SP2?  If you are, I just logged a case with Autodesk this morning on feature line instability with SP2.

I am not sure about SP2, I have a quarterly subscription and it
automatically updates periodically. I just noticed this last week. It
seems to be that the "inferred points" on a feature line are only the ones
corrupted. It is a huge problem for me.

That sounds about right.  I logged the case with Autodesk on this about an hour ago.  It seems to be exclusive to SP2.  I would uninstall SP2 for now.

Todd,

How do you uninstall a Service Pack?

Dave

[ToddRogers-WPM]

Go to your Control Panel.   Add/Remove Programs or Uninstall a Program.  On the left hand side click on View Installed Updates.  They can be uninstalled from there...

Thanks Todd! Every day I learn something new here.

[ToddRogers-WPM]

Indeed.  So do I !!

[dan]

I just checked and it seems that I do not have SP2 (Civil 3D 2016) installed.  I only have SP1.  However, I am definitely still having the corruption problem.  What do you suggest?

[ToddRogers-WPM]

I logged a case with Autodesk.  Haven't heard anything back from them yet.

[ToddRogers-WPM]

Attention colleagues.  I just heard back from Autodesk.  See below...

Dear Todd,

Thank you for patience. My name is . This case was just escalated to me for my review and I will be assisting you with your case. I was able to confirm your findings and also confirm that it does not happen in Civil 3D 2016 without Service Pack. So I will go ahead and log this with development.
The ticket number is DE27807 and is linked to this case. Per process I will be closing this case out, but please know this is on the front side of support.  Behind the scenes this will remain active and further investigated by our development team here for future consideration in updates and product releases.  To further help compel the need for this functionality fix, please navigate to the link below to submit this feedback.  This will go to the project manager of the product and he in turn will bring this to the product review /discussion with the development team for further consideration on top of these efforts above.  This is a great tool and can help build further momentum in pushing this request through.

What kind of surface corruption? Never seen a surface corrupt.

[ToddRogers-WPM]

It's actually a feature line corruption. If you add elevation points to a feature line, run an audit, it grays them out and in some instances they are deleted.

Thanks for the info!

I am again having this problem.  It is a different project than before, but it is the same problem.  I never heard back from Autodesk...any ideas.  This is getting to be a real pain.

Have you tried installing the Feature Line Hotfix?

[dan]

I did as you suggested. However, after I attempted to use the Grading>Edit
Feature Line Geometry>Break ... the DEM was corrupted just as before. What
it does is set all of the intermediary points (the points of elevation on
the feature line that the user does not create) equal to "0". In some
cases, you cannot set them to a proper elevation even when selecting points
on both sides of them to a realistic elevation.

Please provide another solution.
