AutoCAD Civil 3D :: Data Referenced Surfaces And Alignments
Oct 29, 2013
We have a HUGE number of data referenced surfaces and alignments that need to be moved to a different group of folders. Is there a simple way to do this without breaking the references (each surface/alignment) is referenced into multiple drawings.
The project was divided up into a bunch of little mini projects so now we have 500150_A, 500150_B etc (around 90 of them). Each one has a dwg file with a surface and at least one alignment and that drawing is data referenced to all the other sheets within that mini project. Each project has _Shortcuts, drawings etc.
The powers-that-be have decided to 1) change the project number (from 500150 to 500152) and 2) to bring all these mini projects together into ONE project.
We've confirmed that each surface/alignment has a unique name which means that there shouldn't be a conflict in that regard.
I've just used Data Shortcuts for the first time but I've found that I can only reference in Surfaces and Alignments. Is this correct? The file I am creating my model in, has Corridors/Feature Lines/Gradings as well but I can't create Data Shortcuts for these? or am I missing something?
I have created a data shortcut to a surface using Civil3D 2011. When I create a reference to it in another drawing, it shows up in the Prospector but nothing shows up on the screen. I have played with the surface style and made sure all the layers were on and tried closing and reopening the drawing.
I have also tried to reference it into a brand new blank drawing and I even tried to reference a surface in a different file that I have referenced several times before (in 2010). Every time I get the same results. It seems like the surface is there, but I just can't see it.
I cant get this one. I have created an alignment in a drawing and created a shortcut. When I data shortcut that alignment into drawing "A", its all good. Alignment starts at station 10+00. When I do the same data shortcut into drawing "B" the alignment is starting at station 0+83.33. Why?
Not sure if this is something that has been going on a while, if it is a design flaw, or if it just a workflow thing that we should be more mindful of, but here goes:
1. I data reference an alignment into a drawing.
2. I later data reference in a profile that was created from and associated with that alignment.
In this scenario, Civil 3D creates a duplicate alignment for the profile i.e., the orginal alignment is in prospetor as 'Alignment A' and the profile being data referenced in creates a 'Alignemnt A (1)' duplicate and associates itself with it.
This also happens if I bring in a different profile created from the same alignment IF the alignment was already present as a data reference in the drawing.
This seems wrong. It doesn't do any of this if I data reference the profile in first...
I need to figure out a way to sample multiple surfaces for multiple alignments.
Example 1: I am creating cross sections for a river dredge showing the pre-dredge bathymetry, design dredge elevation, and post-dredge bathymetry results. I have 100's of alignments that I need to sample 3 surfaces and display in profile view. Due to the clients requirements for display, using the cross section tools don't work for me, so I have resorted to using a seperate alignment for each cross section.
Example 2: Working in a subdivision with many utility alignments it would save quite a bit of time to be able to choose a group of alignments and sample multiple surfaces in just a few clicks.
Is there any way to determine the source drawing of a dref'ed object? I'm not seeing anything in COM or the .NET API's, hopefully I'm just not looking in the right place.
I created DRefs to an Alignment plus the Existing and Proposed Profiles. I ended up with 3 alignments with one profile attached to each of the second and third alignment. The second and third alignments are name as <Alignmentname> (2) and <Alignmentname> (3). I deleted them an just brought in the profiles but they each created a new alignment.
I searched the board and Google. What I found was that it's recommended to keep the profiles in the drawing in which the alignment was created. I usually do that. But I've been working at a 1:1000 scale and now the Engineer wants the profiles plotted at 1:500. I don't like changing the scale in the drawing so I thought I'd created a new drawing with that scale. It doesn't look like I can do that now.
is it possible to get the alignment name which the corridor surface is built from when the surface is being data referenced. in other word no corridor as the middleman.
the way i see it is when corridor suface is referenced, it becomes a regular surface and loses some properties such as parent alignment.
i am still using COM. maybe .net can do it? either way works.

I have a design file that has and alignment with 3 profiles (one surface profilke and two layout profiles)
All these are data referenced to the project. Then they are data referenced into a new file. I bring in one of the profiles that brings in the alignment. Lets call it "Main Street". Then I create another reference to another one fo the profiles and it brings in a copy of an alignment and calls it "Main Street (1)"
This is a pain because I cant get a profile view to show all the profiles because the profiles are associated with three different alignments "Main Street", "Main Street(1)", "Main Street(1)(1)"
This is only happening with one of the of the alignments. The other alignment has all its profiles listed under one alignment.
When creating my plan set, I need to data reference pipe networks into other drawings than that in which they were designed to show crossings in profile views or to separate out profiles into managable drawings. When I do this, if I have swapped a type-13 inlet for a 10' type R inlet or something during design, the data referenced pipe network will replace the 10' type R with a default inlet. Also if I have swapped a proposed 30" pipe for an existing 30" that have different styles, the data referenced pipe network will revert back to the proposed 30" pipe. how to make a data referenced pipe network reflect what is currently in the design drawing?
My question is "Can I create surfaces, profiles, & alignments using AutoCad2012?"
I know if I had Civil3D2012 I could do it, but can it be done with the Regular version I should say.
At my previous job I was using Civil3D2010 (darn economy Government job did lay offs) and now I'm using CAD2012 with new employer and I'm realizing that there are a lot of functions/commands that I don't have.
I have 2 different surfaces (Existing Ground & Proposed Pipe Invert) that I want to have the elevations shown for in a profile data band, but I want them to show at the design profile's PVIs (Proposed Road). Is it possible to set up a data band style that samples at one profile's geometry points but displays the elevations from these points from a different profile? My workaround is to set the data bands to all sample from the design profile first and label over the design profile's data band but I'm hoping for a cleaner solution. Attached is an image showing the profile view in question.
How do I project the Proposed Road Level information from Road_1 at the intersection of Road_2 (Alignment_GA.jpg) onto the Start of the Profile for Road_2 (Alignment_Profile.jpg) to give me my tie in start point?
How do I obtain the exact change of the intersection Point? How can i extend Road_2 onto the horizontal curve of Road_1 so i know they exactly intersect?
I have a more than 10 number of alignments of road network in MX Road. I imported these alignments into Civil 3D. The problem is I am not able to edit these alignments.
I have two alignments that are not parallel that make up one corridor. Each alignment has a separate profile running along it. At stations where I have a template drop in my section editor, it is not representing what is really happening because it just is perpendicular to one alignment. Is there a way to develop a secondary alignment that will have my section editor show what will be parallel to both alignments.
How to join 2 alignments which are continuing a same road? Is it even possible ?
I have tried to explode them into polylines > join the polylines and then reconstruct the alignment again but it crashes on everything longer than 15 miles
I am going through our Civil 3D template and purging all layers we do not use. However, there are four assembly layers AutoCAD won't let me delete, but I cannot find any style or object referencing them. If it matters, the layers are C-ROAD-ASSM, C-ROAD-ASSM-BLIN, C-ROAD-ASSM-OFFS, and C-ROAD-SCTN-DIAG.
I am working in Civil 3D 2010 and I created a surface a while back which 4 pipe networks have been referenced to and the surface has been data shortcut'd. I am now facing the issue that the surface needed to be renamed.
I looked in the Data Shortcuts folder and the name didn't change on the shortcut. All the pipe networks have errors now cause it is looking for a surface that technically no longer exists.
I tried deleting the Data Shortcut and creating a new one with the new name and resetting all the networks to the new surface but I am still gettting errors.
Is there a step that I am missing to get all this to link together properly with the new name?
I've lined up an image myself in Civil 3D over a topographical survey but now I want to export the image as a geo-referenced image so it can be brought into Mapinfo and Tuflow in the right place, coordinate-wise.
My question is - is it possible, and how do you do it!
I am using Civil 3d 2012. What I have is a surface along railroad tracks. Each set of tracks has a different alignment because they aren't parallel. I have a baseline alignment with my stationing set on that. What I want to do is have one profile view showing the multiple track alignments based on the baseline alignment. I can't use the offset alignment because they aren't parallel.
I'm trying to create two offset alignments (one on each side of my centerline alignment). For some reason I can only create an offset alignment on the left side of my CL alignment, but not the right side.
I created an alignment from the arcs at my intersections. When I go to the geometry editor under grid view it only shows the first curve.Does c3d support discontinuous alignments? When building edge of pavements at intersections is the workflow to make a new alignment for each intersection?
I need to put a reverse curve on an alignment. I have tried using two free curve fillets,(between two entities, radius). the first curve was fine, but it would not allow the second curve. I also tried using a floating curve ( from entity radius through point) first, but it did not work.
Loving Pressure Pipes so far, taking us a bit to get them setup to work the way we want.
Using Pressure Pipes to design two water mains, the first main is a straight run, and the second one starts off of a Tee that I added to the first. This part seems to be working fine, now when I go back and use the Create Alignment from Pressure Network to create the alignment for the first main everything seems fine, but the second one is where I am running into my problem. When creating it, if I don’t select the Tee that I used as the starting point the two alignments don’t intersect, however if I do select it something crazy happens, my start point for my second alignment snaps to 0,0 instead of the Tee. I have tried a couple of different times with both Tees and Crosses. I get a little bit of a different result with Crosses, if the cross is the start Point of the alignment it behaves the same as a Tee, snapping to 0,0, however if the alignment goes through the Cross it is created correctly.
