AutoCAD Civil 3D :: Stream Restoration Design
Jun 24, 2013
How to do a stream restoration design with corridor modeling. for the low flow channel pool, i will have alternate riffle and pool sections. my understanding is riffle for X feet, then pool for Y feet, then repeat, per the riffle to pool spacing requirements.
my question is regarding the left pool and right pool sections. please see attached images. for left pool, width A > width B and vice versa. A+B is the same for both left and right pools. left pool assembly has to be applied when the centerline alignment is curving outward to the left side, right pool when curving outward to the right side.
is there a way to specify in corridor modeling when an assembly is to be applied based on the direction of the centerline alignment curves?

I am currently working on a Stream Restoration project and am really struggling to find a flexible solution for modelling natural river corridors.
My Landscape Architect has provided me with a set of 2d-Polylines representing the proposed river alignment as well as some embankment lines. (Spline.jpg)
My first attempt was to create a corridor with a cross-section consisting of some generic links targeting my polylines. see attachment (Corridor.jpg). Obviously it results in a total mess. So I tried splitting the corridor in multiple sub-corridors targeting different lines as suggested by Dana Probert in her class on Stream Restoration. (Corridor1.jpg) However, given the curvature of these lines, the corridor simply never works as expected.
Question #1: is there any way to create a ‘smart subassembly’ which would prevent those bowties? Ideally I’d like it to be able to connect to subsequent vertices of the targeted line. Maybe the subassembly composer is capable of doing such magic tricks?
Since the corridor approach didn’t work I tried adding the Polylines as breaklines to a surface without any other definition. To assign some elevation data I converted them to Feature Lines. The original 2d-Polylines have been set to Fit -> Quadratic though and Civil 3d just refuses to accept them as they are. So I’d go splineedit -> convert to spline and then Flatten to convert them to Polylines back again.
This way I can convert my Polylines to Feature Lines, assign elevations in the elevation editor and add them to an empty surface. After playing around with the mid-ordinate distance and interpolation values I end up with something usable but difficult to manage (Surface feature line.jpg). The Flatten command converts my beautiful splines to a set of interconnected lines and arcs, which aren’t that easy to control. And for all this effort the resulting surface isn’t as smooth as expected (Object viewer.jpg).
Question #2: is there a way to convert splines to feature lines, or better yet – add splines as breaklines to a surface and derive their elevation from a profile?
My current solution to this problem is converting the 2d-Polylines to splines, and then back to Polylines via Splineedit. This way I get a Polyline with tons of straight but short segments. I convert them to feature lines, assign elevations and add as breaklines to the surface definition. The resulting surface is super smooth. It just isn’t easy to modify because of the amount of vertices that have to be moved to do any adjustments.
Question #3: Do you know of any better ways to approach this subject? All of the methods I’ve tried would have worked perfectly with a simple corridor. It’s the curvature that renders them useless.

I'm a beginner user of SSA (Storm and Sanitary Analysis) and I really need to import a GIS data with the elevations of a stream in order to run a simulation. But, when I import the data all the elevations are zero! What should I do?

I am looking into switching to AutoCad Civil 3D from MxRoads. Up to now I have been using Mx and have a large back catalogue of roads work all in MX formats, Input files, Genios etc.
Given that Mx is string based and Civil 3D appears to be section based, I'm wondering if when you import a genio created in Mx, is there a way to "link" a carriageway string to the master string, without having to recreate the alignment from scratch. If I needed to do a quick change to a vertical alignment or a road widening I want to be able to do without reinventing the wheel! I need to ensure that the program can recognize the relevant way string that matches the Master string.

I'm not getting the design levels of assembly, just major offset and elevation, how can i get all design levels from where my assembly is changing and where it is matching to the existing surface, is there any band problem or anything else, im sending the view that how i'm getting my cross section and also i want to know that how can i control text size because it is too big for sections.

The following video show a dam in China using Infraworks and Civil 3D URL....
During the first 25 secs or so, there is a sequence showing a disposal area created in Civil 3D but with a texture that isn't the draped aerial image (and there are further examples of this elsewhere).
How does one get surfaces etc that aren't derived from a corridor to show in this way in Infraworks. There doesn't seem to be any workflow in the available information to address non linear projects.
Additionally the 3ds Max workflows seem to be geared up for linear projects e.g. roads only - any tips for non linear projects e.g. earthworks platforms?

Conceptual design process for a new subdivision with say 100+ lots, and 5-6 roads within it.
What I'd like is to learn a workflow that lets me adjust the alignments/profile with a minimum amount of effort to re-layout 100+ lots, and which lets us explore design options more interactively. Once we pin down a few alignment options, I would create a simple corridor with multiple baselines to develop the grading concept.
One thing that irks me so far is that the Create ROW command is nice, but it's not dynamic to the alignments.How do you handle cul-de-sacs on this process?

I am pretty new to subassemblies and corridors and I think I have the jist of it but I have a few questions.
How do I lower stations of my corridor? I am making a grassed waterway and my corridor seems just ride on the surface. I get to the parameter editor but the elevation design value is grayed out, so I can't change it.

We're moving to Trimble Access on the survey data collectors which means that we have to export design data using Trimble Link and then use Trimble Business Center to examine the data and do any editing before sending it to the field.
So far I've found that alignments, profiles and surfaces seem to transfer OK. Corridors however have been an almost total failure.

Working in Civil 3D 2014 SP1 I have a Design Profile that I have created by setting the Existing Profile to 'Static' and Creating a Copy of the Existing Profile... This leaves me with a Design Profile that follows the Existing Surface. The problem begins when I delete a section of PVI's and introduce new 'Design PVI's'... I have found that at apparently random times my Design PVI's have been lost and replaced with the original copied PVI's that follow the Existing Surface. This has occurred more than once and I can't find any reason as to why this may be occurring...?
Currently using Civil 3D 2013 & 2014 SP1

i have a site which has a mound in the middle, and quite a few drainage swales running downhill from it, radiating in all directions. i want to calculate a rough estimate of how much fill is required to fill in all those swales (roughly). picture that the existing ridgeline "noses" will be left as is, and the valleys in between are the ones that I want to fill in. the project boundary (toe of slope) is the elevation that I want to hold.
i tried grading tools, and corridors as well, but could not come up with a good way to do this. what I ended up doing is i laid out some feature lines that follow the existing ridgelines down the hill (the banks of the swales), then created a feature line of the project boundary (draped on EG), and a feature line at the top of the mound as the highest elevation, created a TIN from those feature lines so that it triangulates across the swales, and then ran a volume comparison. not the best way i know, but could not think of a better way at that moment.

A trick to make automatic a dimension line for the distance between the existing alignment of a road and the design alignment.

I am currently experiencing this error when basically putting an Inventor 2012 file (part or assembly) on a flash drive and then loading the file(s) onto a different computer with Inventor 2011 installed. Once in Inventor 2011 and trying to open the necessary file(s) I receive this error. Is there some difference between the 2011 and 2012 files that is causing this to happen? Or the face that I am using the student version of both?

I have drawn a 3d polyline across a stream channel and want to rotate it about the x-axis so i can trace the elevation profile of the crossing. 3d rotate in civil 3d 2012 is not allowing me to pick the axis i want to rotate about? This worked great in previous versions? This is very simple and i dont have a need for a surface or sections or profiles...i just want to trace the 3d polyline profile.

My computer went down two weeks ago, bad enough that I had to get a new hard drive and start over. When I went to install Inventor, I kept getting Errors 1335, 1334, then error 1406 during installation. I seemed to have gotten beyond those, but when I went to open certain assemblies I started getting "Error in reading RSe Stream (4 not equal 2)" and "Error in reading meta types in RSe Segment AmDcSegment in..." and them it shows a certain file it doesn't like, sometimes repeating for multiple files. I clicked on the communication icon in the lower right of my Inventor screen and it said a maintenance update was available. I installed SP1 and tried again. Same problem. I clicked on the icon again, and it told me SP2 was available. I installed it and tried again. Same problem. I clicked on the icon again, and it told me SP3 was available. I installed it and tried again. Same problem. I clicked on the icon again, and it told me SP4 was available. I installed it and tried again. Now I can't open Inventor at all. Inventor crashes just on trying to open up. I've been running Inventor 11 since it came out with no issues whatesoever. Now I'm two weeks behind with no end in sight.

I've got a highway project for which I'm modeling the corridor but the design profiles given to me are for the right lane top edge (ETW) and not the centerline (crown). This is an undivided planer roadway with a typical 2% cross-slope. How can I use that profile for the right edge to run my corridor? I can't seem to get the corridor to use the super table that is attached to the centerline when I use an offset assembly. Is an offset assembly the right way to go with this design?
What I've done just to get going is to take that right edge design profile and draw it in my centerline profile view, then lower it 0.24' (which is my 2% normal cross-slope for a 12' lane) and then use that as a centerline profile and let my normal super assembly and table data control the corridor through the supers. So far that is working--but is there a better way to do this?

i can't drag a block from the design center into any drawing. i have to go into the design center right click on the block, click copy, then go back to my drawing and paste the block. this has just started happen, before i was able to drag and drop with no problem. there is no error message the only thing that happens when i try to drag a block from the design center is when i'm back in the drawing the cross hair has a circle.

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.

It seems like I used to be able to do this in 2012.
I created a design profile and used the copy profile command. I close the layout toolbar of the original design profile.
When i select the copied design profile to grip edit a pvi, the existing ground profile and copied profile disappears and i cannot grip edit.
I have also tested this with an OOTB template.
Question: How to be able to grip edit a copied design profile in 2012.
