AutoCAD Civil 3D :: Road Network Surface

Nov 19, 2012

I have make a road network. Then i make a corridor surface using corridor extends as outside boundary. I also create a boundary in the interior side of the roads with interactively tool, and i use it as a hide boundary. The corridor surface look fine but when i am trying to make a finish Ground Surface pasting the corridor surface after Existing Ground surface then the hide boundary of corridor surface make holes in finish Ground surface.

AutoCAD Civil 3D :: Pipe Network - Crescent Road - Profile View

Jul 30, 2011

If I have a Crescent Road (P - shape) where the Alignment returns to itself, when i draw pipe network parts in profile, the pipe network gets drawn wrong, ie. the tie-in structure at the intersection is drawn at the wrong station.

My understanding is that the structures will get drawn at the station closest perpendicularly to the alignment, so the structure is going to the end station as opposed to the beginning simply because the end segment of the alignment is closer.

Is there any way to make a structure use a different perpendicular station (without shortening the alignment)?I don't want to move alignment or structure.

AutoCAD Civil 3D :: Road Surface Becoming Flat?

Jan 30, 2013

running an assembly in to the road corridor and creating a surface. i have designed a network of Roads in CIVIL 3d in which whole network is surrounded by a Loop road. The loop road cross fall is unidirectional (2%) and 4.5 wide. I have used LaneOutsideSuperWithWidening subassembly to create  the assembly of the road. This doesnt contain any kerb or footpath but only road channel lines, The corridor run soomthly but after creating the of the loop road corridor the surface is becoming flat meaning there isn't any cross fall acoss the road but in the assembly crossfall is there. If i run the same assembly in another road alignment the suface is coming absolutely correct.

I also tried different road assemblies to run along the loop road but the result is same no cross fall across the road.

AutoCAD Civil 3D :: Pressure Network - Don't Follow Surface Anymore

Jan 31, 2013

So, I really like the ability to have a pressure network pipe follow a surface but, what if I no longer want the pipe to follow the surface? Is there any way I can get rid of all the extra grips that are added to the pipe in the profile? The only way thing I've come up with is to delete the pipe and recreate it.

AutoCAD Civil 3D :: Create A Profile Or Section Using Network Surface?

Mar 27, 2013

I have in front of me a survey of a small section of road (it's only 10m x10m or something). I want to be able to create a profile along the road section to demonstrate the surface level changes. I have created a network surface but Civ3D doesn't seem to able to use this type of surface to create a profile. Is there anything I can do, perhaps a way of transforming the network surface into another type of surface? Or am I going to have to manually create this profile in ACAD!

AutoCAD Civil 3D :: Can't Change Reference Surface For Pipe Network

Sep 4, 2013

Civil 3D data shortcuts. 

So I first created a drawing which included a surface called "CONTOURS" and an existing sewer pipe network. I then created a data shortcut of the existing sewer network and started a new drawing with a proposed sewer pipe network.

When I received better contour data, I created a new "10FT EXIST CONTOURS" surface in the existing sewer drawing and switched the reference surface for the existing sewer structures and pipes to the new "10FT EXIST CONTOURS" surface. And of course I deleted the old "CONTOURS" surface because I no longer needed it. 

Now, the part that makes me want to pull all my hair out! When I open the proposed sewer drawing I get all the error messages that "Reference surface 'CONTOURS' not found in reference drawing" for all 22 of the existing sewer structures.

I've tried deleted the existing sewer network in the proposed sewer drawing and recreating the data shortcut but nothing makes the errors go away. Is there any other way the existing sewer structures could be referencing the deleted surface that I have not thought about? How to get the error messages to clear?

AutoCAD Civil 3D :: Change Pipe Network Reference Alignment Or Surface

Dec 14, 2009

I want to change the reference surface for a pipe network with existing pipes and structures. however the changes will only affect new objects, I have to manually change the others one by one. Even with the vista open I can select multiple structures, but when I click in the reference surface column of one of the selected structures, all the others are deselected.

AutoCAD Civil 3D :: Pipe Network Move Multiple Manholes To New Surface?

Apr 19, 2013

Just as the topic says. I have about 40 manholes referenced to a surface that has no changed and I need to update them. I can go thru one by one and pick "structure properties" and change the surface. I did change the surface under the network options, but they all still reference the old surface.

AutoCad 3D :: Creating Surface For Road At Section

Oct 9, 2013

I am having difficulty in creating a surface for my road in 3d at this section, the points given are along the center lines and so far have been fairly straight forward for the fall of the road as there have been no junction up until now.

I am not using 3dpoly at this point, just plain old lines.

Road 1 displays where i am having issues and Road 2 display how it looks in 2d format (only at an angle)

AutoCad 3D :: Moving 3D Objects In Relation To Road Surface

Oct 7, 2013

I use geophysical software which exports 3D objects to AutoCad in relation to the flat surface - "zero" level. Most often clients want to get results in local height datum (in relation to the road surface which has usually slope and is never perfectly flat).

Is there any method to move all objects automatically and show them in relation to the road surface? Ideally I would like to define road surface with three lines (two side lines and center line). Is there any plugin to AutoCad that can do it? If this operation goes beyond the possibilities of AutoCad, can you recommend me a software (eg. AutoCAD Civil), which automates the process?

AutoCAD Civil 3D :: Default Pipe Network Layer (Not The Structures Or Pipes The Network)

Dec 7, 2012

I am using Civil 3D 2013. I work in an office where we have a few different flavors of Autocad (LT, MEP, regular vanilla AutoCAD etc...) and versions (2010 LT, 2011, 2012, 2013).

For the most part there isn't much inter-office drawing coordinate that has to happen, but there is the occasional project where multiple disciplines (Structural, Mechanical and Civil Site) have to share drawings.

The specific problem I am having is when I share my 2013 Civil 3D drawing with a user using 2011 MEP. He gets the typical rectangle for the proxy objects (in my case, my pipe networks for sanitary and storm drain). We've tried downloading and installing various object enablers, but there doesn't seem to be one for a 2013 to 2011 scenario. So I setup my parts to be on layers that he can just turn off. HOWEVER... the actual pipe network (not the structures, parts, labels etc... the network itself) ends up on layer 0. For this specific project, I do the old (ssget "x" '((8 . "0")) search to select all objects on layer 0, add those objects to a selection set (pselect), then in my modify objects dialog I filter for pipe networks, then change the layer to something other then 0.

While this is a workaround that works for me, what I really want to know is if there is a way that I can change the default layer that the network (again, not pipes, structures or text, the actual network) so I don't have to use the workaround. Any thoughts?

P.S. It's killing me that I had to create a new Autodesk login and now all my AutoCAD "street cred" is lost

AutoCAD Civil 3D :: Customizing Road Profile Output

Feb 27, 2013

I am new to Civil 3D and need to customise the look of road profiles so they look like they were produced from any of our other civil design software packages that we use (to maintain standards between offices etc).

The attached picture is what I need them to look like. I want to show both the natural ground (the dotted line) and the design road line (solid). Then I want to write on the profile the station, natural level and the design level.

I've got the Mastering Civil 3D book (and a few others) sitting on my desk.I worked out how to turn off the grid on the default profile althoguh that was about it.

AutoCAD Civil 3D :: Road Modeling - Grading / Corridors

Dec 2, 2013

I am preparing to model a road surface for a waterline project.  I would like to be able to generate sections at desired stations showing the sewer, storm drains and joint utility trench along with the proposed water line. My plan is to model the road surface using a surface created from gradings and then create the pipe networks and joint trench.

My question is whether gradings or corridors would be the way to proceed.  I have preliminary design data on the road surface which is sure to change.

AutoCAD Civil 3D :: Trimble Export Road Files Corrupted?

Trimble Access, Civil 3d  2012 export road problem

when I export a road file to my TS2 it becomes corrupted (file size 50% of what it should be.

4 months ago there was no problem. The weird thing a is that the other worstation in the office has this issue to.

Here's what I have done to troubleshoot: swapped out both data collectorsexported this rxl file to a virtual instrument on my desktoptalked to cansel and autodesk but the said they haven't seen this problem. I can rule out the following.
 
trimble/autodesk software, hardware ( to much a coincidence that both work stations have this problem)Data Collectors swapped out -  file size of the corrupted rxl were the same on the virtual deskto instrumentcorrupted dwg  - exported a road six months ago, now re-exported and the new file is corrupted.

AutoCAD Civil 3D :: Smooth Road Profiles Created From Lidar

Aug 14, 2012

We have lucky enough to obtain LIDAR for most of our small City as well as ground only points.  My problem is that profiles produced using it are rough and jagged (see attached).  I've tried contour smoothing to no avail as well as point removal.  Perhaps I haven't just tried enough options.

Should mention also I have breaklines along the CL alignment as well as Edge of Pavement.

AutoCAD Civil 3D :: Label Style - Design Road CL Profile

Apr 9, 2010

how to create a label style for design center of road (simple tangent) in profile that will work between multiple profile views. I've used the 'Create Multiple Views' profile view wizard. I use a horizontal dimension style label for CL road (looks just like an autocad linear dimension). I'd like the label work across separate views i.e. stop at view end, pick back up at view start.

The label I currently use is simply a line component from tangent start dimension to tangent end dimension and the text component is anchored to the line midpoint. Label looks as intended for normal use. For some reason the line drops as if looking for the actual pvi at the right side when i use multiple views.

AutoCAD Civil 3D :: Adjusting Intersections Secondary Road Profile

Jul 9, 2013

I went forward designing intersection profiles with limited survey and simply made an educated guess for the secondary roads pgl tie in point. I have received updated survey and when I move the profile end point to meet existing grade it adds another pvi effectively holding the profile grade I set preliminarily. I'm keeping the lock point. Is there something with the return/ offset profiles preventing this edit? What is the proper work flow?

AutoCAD Civil 3D :: Storm Crossing On Road Profile View?

Apr 16, 2012

I have a storm crossing shown on a road profile, and the ellipse that represents the storm pipe is only showing part of the inner wall (I've attached an image). This pipe is skewed slightly, but the entire pipe crosses the road alignment, and this should not make any difference.

Also, is there any way, yet, (I'm using C3D 2011) to have the label show not only the pipe name, but also the invert where the pipe crosses the road alignment, and remain dynamic,? In other words, without having to edit the label text, and lose the dynamic capability. Land Desktop would do this, but it was not dynamic, of course.
