Sample Line Sections Not Updating from Corridor Xref

[Anonymous]

Hi all,

I'm running into an issue that I've spent way too much time trying to figure out while creating my section views. First off, I'm running Civil 3D 2014.

What I am doing: I am creating section views from a corridor I have xref'd. I xref my corridor (I've tried both overlay and attach), set my sample lines and sample sources, create my section views and everything looks great. Where things get weird is when I rebuild my corridor.

What's wrong: I need to change something in my corridor, so I go to my corridor file, make my change, and rebuild. Save. Go back to my XS file, synchronize references and reload my xref. I look at my section views and nothing has changed. So I go to my Sample Group Properties and look at the sections tab and no sources are shown! Now I look at each individual sample line properties and it shows all my original sources. Just for kicks, I completely detach my xref'd corridor and resynchronize all. My section views still show my surfaces and links as well does the individual sample line properties. I can reattach my corridor and re-sample sources in my sample group, but now my section views show both the old and the updated links and surfaces! Somehow, my individual sample lines won't forget any data pulled from the original xref'd corridor.

Any ideas what could be causing my issues?

I've seen sampled sources disappear if these steps weren't all taken.

1. Change the Corridor update mode to "Automatic".

2. Set Xref attachment type to "Attach" for the Alignment, Base & Corridor source dwg files in the Cross Section source drawing.

3. Create Data References into the XS.dwg for the following surfaces (And only use these for sampled sources!).
EG
FG
Datum

Note: There is a distinct difference in the icons for the surfaces between Dref & Xref.
The icon without the little black arrow present is the Dref & one to be sampled.

Often times users will accidentally sample surfaces read via the xref (which is possible) but doesn't produce the same desired results as the dref'd surfaces.

Also, do you have a companion corridor frequency line @ each sample line?

Jay,

Thanks for your response. I apologize for the delay in mine, for I was out in the field during the last week.

To address your first two suggestions, I do automatically update the corridors and my xref is set to attach. I think it's the xref that's causing me the trouble. I am actually trying to sample my surfaces directly from my xref, rather than dref'ing my surfaces. The only reason I am trying to do this is because the DOT tells us to do it this way. I'm not sure if that's just a suggestion by them or if they actually need us to sample from xref. But you're saying that commonly causes issues?

My frequency lines do not match the stations of my sample lines. Should they?

Thanks again (and sorry for the delay),

RJ

RJ,

Yes that's what I'm saying, when I have users here describe what you've described as far as sampling a surface via an xref (which, AFAIK, is supposed to work) and I have them instead sample ONLY Data Referenced surfaces, the problem always goes away.

When xref'd surfaces are sampled instead the problem always returns here.

You always want to be sure to have a companion Corridor Frequency Line for each & every Sample Line.

A work around for your original situation. 

I ran in to the same issure where the corridor would update but not reflect the update in the XS. To get around this you have to kind of "Force" the update through. I click a sample line, hit sample more sources in the ribbon tab. In the dialog box that pops up I dont change anything and just hit apply and then ok. This forces the lines to look at everything again and the corridor update gets pushed through to the XS. Im sorry this is way later than your original post but I didnt see this workaround suggested so i thought id through my 2 cents in.

Jatchison, that is exactly what I ended up doing! What Jay mentioned above was correct, but it did not completely fix the glitch. I spoke with our CAD consultant and he said that it was a known issue and for now the only work-around was what you just described. I really should have posted that here in the discussion after he told me this. Thank you for your post!

Corridor assemblies do not update in section view when corridor is XREF

This same thing happened to me in 2015 & 2016. I was told by Autodesk support that my corridor drawing became corrupted, even though the corridor drawing worked fine, audit reported no issues, and recover reported no issues. I had to create a new, empty drawing using my corridor template (same one the corridor was originally created from) and insert the "corrupted" drawing into it as an exploded block. I saved that drawing over the original one. That fixed whatever was causing the XREF to not work correctly. When I asked how my corridor drawing became corrupted, but only as an XREF, I was ignored and the case was closed. They said my corridor template did not show any issues, so it wasn't the template. This was from a very small, simple corridor. 

There is a serious, internal flaw with corridors that Autodesk hasn't been able to fix for at least three versions that can cause corridors to become corrupted for no reason.

I have a very similar situation only my section views are not showing one C&G subassembly.

Everything else is displaying correctly.

Tried the knowledge base link above and it didnt' fix the issue.

I am using an "attached" corridor xref to get the corridor into my section views.

Unfortunatelyl mine is a fairly complex corridor drawing. No way I'm rebuilding it from scratch.

If I can't figure it out, I guess I'll draw in the C&G manually.

Grrrr!

Save a copy of your corridor drawing. Then try inserting the corridor as an expoded block into a new drawing and naming it the same as your original corridor drawing. Then check your section view drawing and see if the subassembly shows up correctly.

I figured out my issue, and it may help solve yours too.

Create a frequency section in your corridor exactly at the same station as the sample line.

I had forgotten about this tip that I found previously.
