Superimpose Profile Problem

[klugb]

Has anyone seen, or know of a fix, for this problem? I have a superimposed profile (cyan line) that stretches back near the beginning of the profile view.

A defect was logged with Autodesk on a very similar superimposed profile
issue with the 09 version.

And, IIRC, it has to do with the alignment starting outside the border of
the surface. Somehow move your geometry around to get the alignment inside
the surface and that goes away. (I.e. add a surface point or two to get the
border to warp around the alignment.)

Of course, my memory ain't what it once was.....

I'm leaning toward defect. It is a profile that was created from 3D linework, so it's not referencing a surface.

Thanks for the help

Bruce,

Is it possible that the alignment loops around and/or crosses over
itself? Seems like a data-dependent issue. If you can email me a
minimal drawing that demonstrates this problem I'll take a look.

I just sent you the project drawing to your Autodesk e-mail address. It's a 4MB Zip file, if you don't get it let me know.

Thanks

For those watching this thread.

Thank you, Himanshu

He helped steer us in the right direction. We were projecting an alignments profile to another that creates a unique mathematical problem. The PI's & cooresponding VPI's fall into an area that is not perpendicular to the alignment. The alignment had a hard angle point at 123+27.96 which creates a void space on the source alignment.

See Image, just ignore the PC/PT I was playing with a small curve to fix it.

I have the same problem as this, can anyone explain the workaround / Fix for me

Cheers

I have been fighting with this same problem. Here are a couple things that I did to fix it.

First, I made sure that my alignment was completely inside the surface boundary.  Originally the begining and ending of my alignments to be superimposed were outside the surface boundary.  I fixed this and one of my problem profiles was fixed, but the other one wasn't.

Second, I reversed the direction of my alignment to be superimposed so that it ran in the same direction of the parent alignement.  It shouldn't matter which way the alignment runs, but apparently it does, because once this was done the superimposed profile was fixed.

Hope this helps.

I had been having this issue as well bu tI think I found a workaround, at least it works in 2011.

Create a feature line from your aligment/profile you want to project. Then project this feature line instead of the profile. Seems to work.

None of the fixes mentioned worked for me. The alignment is well within the surface boundary, the alignment was already running in the same direction as the parent alignment (I even tried to reverse it to see if it would work), and creating a feature line and then superimposing that line on the profile did not work.

Any other suggestions? I have wasted more time on this that I should be, but now it's really starting to get to me!

Just wanted to follow up and see if this issue has been resolved I've been looking everywhere for a solution to this as well.

Thanks for the solution, Jeff.
