AutoCAD Civil 3D :: Corridor Volumes Into Sections?

Jun 7, 2012

I have sevreal corridors with various spurs.  The contractor wants the cut/fill volume in sections along the corridors, not one big cut/fill calc.  Is there a way to do this in C3D?  I have got the volume table with the chainages on, but he does not want a cumulitive figure for the whole corridor.

AutoCAD Civil 3D :: Widen Roadway Through Some Mountains - Corridor Volumes

Jun 26, 2013

I'm working on a project to widen a roadway through some mountains. The problem i am having is getting the corridor to apply to a future surface so that i can determine the volume difference. my profiles show there should be some cut and fill, but i cannot get the model to reflect this. when i try to preform a bounded volume i recieve a "the surfaces do not overlap".

AutoCAD Civil 3D :: Label Corridor FG In Sections

Nov 22, 2011

We have created sections from our corridor. We see FG and EG, we can use bands for EG from surface. How do we get the FG band to show the elevations for FG? The only option we have is the EG surface. We have tried to create a surface form the corridor in the corridor properties but that surface still doesn't show up in the surface list in the bands. I would have thought this info would be dynamic and come directly from the corridor would it not?

AutoCAD Civil 3D :: Corridor Not Displaying On Cross Sections

Feb 28, 2013

I have a corridor with 2 intersections. It is more or less like a main road with an off-ramp and an on-ramp, both on the same side, with a big triangle shape island in between them. It involves an existing road widening and a connection with another existing road. Since it is a real scenario, the intersections aren't perfect 90 degrees nor the offsets are constant.

Create Western intersection and change offset and curb return targets to design aligments.Create Eastern intersection and change offset and curb return targets to design alignments.Model the corridor as per design requirements.Due to design constraints, I ended up removing both intersections. I didn't delete all the offset and curb return alignments although they're not targeted on any region. Deleting this alignments seems to make C3D crash. the actual intersection definition hasn't been removed, as I read on other threads. I kept on getting a couple of error messages on Panorama Event Viewer every time I rebuild the corridor.

So, the problem comes when I try to output the cross sections from this nice looking corridor. They all look fine until they reach the intersection area. From the intersection onwards, the corridor is not displayed on any cross section. Even way passed the western intersection.

Why the corridor doesn't display on the cross sections passed the deleted intersections?I have a bad feeling that removing the intersection wasn't a good idea in the first place but it's too late now.

AutoCAD Civil 3D :: Corridor Not Fully Showing In Cross Sections?

Jul 30, 2012

I have a corridor with two baselines, one on the south side of the road, and one on the north side.  The south baseline appears correctly in the section view.  It is an asphalt bike trail with a ditch to the left side.  The north baseline was not appearing at all.  The assembly was just a ditch with nothing else.  I changed the north baseline to use the same assembly as the south to troubleshoot.  The pavement comes in, but the ditch still does not appear.

I can see the ditch feature lines on my corridor (see attached), but they are not appearing in the section view.

AutoCAD Civil 3D :: Corridor Assembly Appears Flat In Sections

Jul 24, 2012

I have created a proposed centerline along my existing roadway, which represents along my profile. I have created an assembly for my proposed raod with a crown, and a 2% cross-fall in each direction.

But when I generate my sections, all my proposed assemblies show up in the proper location on my section views, except there is no cross-fall showing on any of them? They are all being shown in my sections as dead flat! 0%? I've been looking for a setting to change this.? I have also deleted, and recreated my corridors and regenerate my sections, only to get the same results!

AutoCAD Civil 3D :: Corridor In Cross Sections Not Updating Automatically (2014)

Jul 11, 2013

When opening a drawing that has  corridor model xrefed in, the corridor section is not updating automatically.

If I reload the xref, it updates.

If I manually synchronize the alignment, it updates.

But just opening the drawing, it does not update.

I have even tried using the OTB tutorial drawings. Same problem.

Not having cross sections update automatically?

AutoCAD Civil 3D :: Elements Of Corridor Not Displaying On Cross Sections 2012

Jun 20, 2012

Running version 2012 of Civil 3d

We have an urban divided highway resurface and widen project.  We have an eastboiund and westbound corridor we would like to get to display on our single set of cross sections

We originally set up our corridor to do the widening and ditches portion and then went on to do the work to set up the model to do the resurfacing.  When we did the sections for the ditches only they displayed fine.  Now that we have the resurfacing incorporated into it the ditches no longer display.

we have reviewed the targets of our assemblies, we have reconstructed the cross sections, to no avai. The software is not doing us any good right now.  Need to get smarter

AutoCAD Civil 3D :: Corridor Section Editor Data Overrides Not Displaying In Cross Sections?

Jan 9, 2014

I have added intermediate sample lines in my corridor.  These sections appear in the section editor and I can make changes to the data.  The changes show correctly in the section editor and section view, however, when I plot the cross sections some of these added stations do not show the overrides.  They are showing the original assembly group parameters.  How do I get all the cross sections to reflect the edited data from the section editor?

AutoCAD Civil 3D :: Copy Corridor Or Corridor Station Values Only?

Dec 13, 2012

Copy a corridor successfully? I'd like to try this just a little worried about the explosion of evil this may cause to my Civil 3D session.

Even all the properties of the corridor setup from one to another would be useful. I'm building one corridor and an 2nd one that matches everything except I need to replace my Assembly with one meant for stripping.

AutoCAD Civil 3D :: Corridor Surface Is Not Matching Corridor Top Links

Mar 21, 2013

My corridor surface is not matching my corridor top links.  see attachments.  this is affecting my volumes!

The section-plan(surface red).png is showing the section editor and the plan view.  the red highlighted line in section is the corridor surface and as you can see in plan view the surface is incorrect and wiggly.

The pdf is all my sections with the red linework being the corridor surface.

AutoCAD Civil 3D :: Composite Volumes

Jun 29, 2012

I have a question concernig a wrong result of computed volume.

EG surface with all EG points H=100.00m

FG surfase, created by FL-Square 100x100m H=101.00m, added to FG surface as breakline.

The Result-Fill=9149.59???

Why not 100x100x1=10 000???

P.S. EG points at above example were around 80, randomly spread at area say 150x150m

When I deleted 76 and moved remainig 4 at the corners of the square, the result is OK 10 000cu.m

AutoCAD Civil 3D :: Volumes Along An Alignment

Mar 13, 2013

I am trying to find an easy way of calculating the volumes I have been asked to do. I have a road, with an alignment created along the centreline. I have created a finished surface which incorporates the cutout for the boxing, and I have been supplied with a surface of the natural (original state) ground.

What I have been asked to do is calculate volumes at either 10m or 20m chainages (station).

Obviously, I can create a boundary, and then shift the boundary to where I want the volumes to be, but this road is 3km long, resulting in calculating 150-300 different volumes. The road is not a straight line either and includes a number of bends.

Is there a quick way of calculating this? Or do I need to use the boundary option?

The way they would normally calc it is to add all the details from the cross-sections into an excel sheet, and makesome complex formulas to figure it out. Even doing the boundary method is quicker than that.

AutoCAD Civil 3D :: Calculating Volumes Between 2 Elevations

Nov 20, 2013

We have a good size channel and the section for the channel varies quite a bit.  We want to find the volume excavated in the channel between 2 elevations (it is the area of sand per the goetech report)?  A template was not used to create the channel surface, breaklines and gradings were used.

AutoCAD Civil 3D :: Inaccurate Grading Volumes

Aug 29, 2012

I have noticed that the value I get when I use the surface volume comparison tool or look at a graded item in the grading group properties box is different than if I calculate it by hand and the discrepancy isn't even consistant.  After spotting this problem in a job I am working on graded two simple ponds to check this.  The first one is 100' x 100' and 5' deep w/ 2:1 side slopes.  Calculating the volume by hand I get 1500 cu. yds but the grading group properties come up to 1506.17 cu. yds.  The accuracy is off by less than 0.5%  The second pond is 100' x 100' and 2' deep with 3:1 side slopes.  The hand calc gets me 654.52 cu. yds. and the grading group properties reads 655 cu. yds.  This discrepancy is closer to 7%. I really need to know if I can trust the volume tools in the program.

AutoCAD Civil 3D :: Cutting Volumes Along A Set Line

May 1, 2013

I am attempting to take two surfaces and cut straight down through a set polyline and get the difference between two surfaces.  Do i want to use the bounded volumes to do this? Or can i simply create two surfaces and and use the analyze/volumes tool and just select the two.  I would then add the boundary to each surface to limit the data.

My concern is since the two surfaces do not meet along the edges which will cause the math to be off.

AutoCAD Civil 3D :: Volumes / Grading And Surfaces

May 30, 2012

I have an existing topo surface created as well as grading for a proposed elevated pad of earth done in civil 3d 2013. I simply want to calculate the cut and fill quantities. I created the grading with automatic surface creation checked on. When I use volume tools to see what the quantities are, it says 0.0 for both cut and fill.

I created another surface (TIN) and pasted the existing topo surface and the proposed grading surface into it and I couldn't get any quantities.

I created another surface (TIN volume) and set the base surface as the existing surface and the comparison surface as the surface created from the grading but again could get no quantities.

AutoCAD Civil 3D :: Comparing Multiple Surface Volumes

I have a big hole in the ground in my model.  Its easy to get the volume of cut with C3D.  But I have a topsoil layer, weathered rock layer and then solid rock, I basically need to break them down into different volumes.  The way I would normally do it is calculate the topsoil, then work out the weathered rock and minus the topsoil, then for solid rock cut I minus the topsoil+weathered rock.  I have attached the 3 volumes I need for info.

AutoCAD Civil 3D :: How To Figure Multiple Volumes From Two Surfaces

Sep 26, 2013

using CIvil3D to figure volumes.  I have a very large aerial topo from a couple years ago to compare against a topographical survey I completed this year.  No problem creating surfaces. 

Question:  In the topo's, I need to get a volume from two different area being a fill area, the other being the borrow area.  Don't want any volume data throughout the rest of the site.

Do I just create one large surface for each topo and designate boundaries somehow?  Or do I need to create multiple surfaces for each topo?  If this is the case, will I need to make sure any breaklines, etc. don't cross from one area to the other?

AutoCAD Civil 3D :: Volumes From Surface Legend Table

I have created a volume surface and associated surface legend table using the cut/fill parameter.

The volumes and areas don't seem to add up, take Cut 2 as an example only if the area of the previous (cut 1) was added could this be possible. There is lots of speculation in our office like does the fill work in reverse?
