AutoCAD Civil 3D :: Shoulder Subassembly - Target Width Alignment At Grade Break
Nov 5, 2012
I am trying to model a DOT project in a fashion that allows a corridor surface creation for not only the finished surface, but also the datum surface. This is a machine control project currently under construction. One of the DOT's typical sections includes a shoulder subassembly with a grade break in it. This particular assembly varies in width at the grade break. I would like to have the option for a target width alignment at the grade break.
Am struggling to pull off some corridor but the standard daylight subassembly is letting me down. It mulfunctions when I connect it to the Generic Linktoslope subassembly. In some Areas it works fine but in others it doesn't. My plan is to apply a ditch at the point where the LinktoSlope meets the ground level and to have this ditch again daylight back to the target surface.
This is my first corridor and I've been slowly working my way through it, but just seem to be running into problems left and right. My latest problem is the following;
I have my Corridor's Subassembly Daylighting set to target my Left side 33' R/W offset alignment. For 90% of my alignment everything is working fine or at least appears to, but I have 3 different areas where the Corridor refuses to daylight from the bottom of the 1' ditch out to said left alignment target even though the ditch is well below existing grade. I've attached 2 screen grabs.

I have a variable sidewalk width and would like my corridor to follow sidewalk as defined by Target Alignment for Sidewalk width (polyline). My sidewalk is merging at ends with roadway however my corridor feature lines presenting sidewalk is not following/merging with target. In all other locations, it follows the target width however where sidewalk merges with road, feature line goes straight.
Attached PDF should hopefully explain what I want to say. Could not attached dwg due to size issue.
I am using Basic Curb and Urban sidewalk assembly wherein my Blvd targets are set to 0 (none).
How can I make my corridor follow sidewalk width target exactly.
I have a profile set up with a surface an alignment and a Water Main. I would like to place grade breaks (Using Profile labels) every 100' along the surface however the increment field isn't available for grade breaks. Weeding doesn't work because it needs to be exactly every 100' I was thinking of creating an expression for it however I still haven't reached that level of expertise.
i need a shoulder subassembly that varies slope in relation to the lane superelevation slope. i know that i can get a subassembly for the shoulder that will follow the alignment superelevation xml data but in my case i can't use it because we are just adding a shoulder to an existing road. we're not changing the superelevation of the existing road, just milling and overlaying and widening. right now i've created a profile of the outside edge of the shoulder that gives me the correct shoulder slope but whenever i change my centerline profile i have to redo the shoulder profiles which is a real time suck.
I was laying out a vertical curve in the roadway profile. I have a vertical curve of 100' in length, however immediately after that it shows a grade break. I do not want this grade break in my profile, I simply want a vertical curve with two grades on the left and right sides. How can I get 2009 C3D to remove the grade breaks? It would be very uncomfortable for someone to have to drive over these in the real world.
I've got a drawing in which the existing ground is so jaggedy that I've got way too many grade breaks (see the attached image). I know I can use the weeding and eliminate the labels every 50 feet, or so, along the profile. But I need to have the ability to only show a specific grade break range. For instance, I'd like for my profile only to display grade breaks between 0% and 2% and not to display anything above 2%. I've tried making an expression, but have been hitting brick walls. I also know I can manually (use the CTRL + click) select the specific labels that I don't want and erase them, but I've got lots of these labels. Any LISP routine or an expression that can accomplish this? [URL]
I'm building up my assembly and I want to add a daylight sub-assembly in order to grade my proposed surface to the existing surface. Typically I would have a 1:3 slope up or down. I have choosen the DaylightGeneral for this and although there is quite a few parameters to play with, I'm only interested in the up/down slope but when I put anything sleeper than 1:4 it doesn't work, I get this red line and circle.
I created a custom assembly that has an offset target. Is it possible to program my subassembly to target only on the side of my subassembly (and not criss-cross onto itself it the target is on the other side)?
I can import my SA fine, but the problem is that the top of it needs to be cut off 1 m above the existing ground (which is already a surface in civil 3d). How do I setup the target surface so that when I import the SA into my drawing, I can link it to that surface and have it cut off 1 m above the surface?
I made a bunch of cross sections of an EG surface and want to define an elevation label at each significant grade break. I see an option to weed by distance but no option that would allow me to place a label at where the slope changes by more than a certain percent.
I found this old thread from three years ago and the best solution to come out of it was deleting individual labels.
I've to make a tunnel on my project. I get some subassembly on web but all the tunnel subassemblies have the target point on Width or Offset Target and Slop or Elevation Target. I don't know whats happens but only my region that owns the tunnel subassembly isn't recognizing on corridor, and isn't drawing on my sections too.
Let's say I have an assembly called Original, as shown below with a 6m wide lane. Now I want to target it to 8m wide for some road widening. Now, will it stretch along the slope of the subassembly (Case 1) until 8m width, or will it just shift laterally to 8m (Case 2)?
I know that we can set the default slope of it, but I'm not sure if it gets overriden due to the Target-width process.
Why I can use fractional number as 0.5, 0.6, 0.7 on the Top Width of the SimpleNoiseBarrier Subassembly?
I am try to modify that value, but the sistem only allow me to use integers number as the 1, 2 , 3., I am designing a road and I am using the SimpleNoiseBarrier Subassembly and I need to use 0.5M as the Top Width value.
I can make a small subassembly that can vary it's deltaX and deltaY based on a 3d polyline (or alignment / profile) in the drawing. However the subassembly does not get put in with default perameters outside of the areas where the targets exist.
I have been trying to come up with a decision tree to tell the subasembly to use default values where there are no targets to use, but I have not been able to find the correct syntax that works for those true/false decisions. My VB language knowledge is clearly lacking.....
Looking for small .pkt file to show how it is done?
I am building an assembly for a shoulder widening. the sholder is 5' paved plus 5' stabalized tying to existing grade at a 4:1 slope. The two shoulder sections are showing up in the cross section but the tie-down is not. I have checked the target and it is set properly to the existing ground.
When I use ImportSubassembly API to import my subassembly created by Autodesk Subassembly Composer into my civil project, it reports error-"eFilerError".
I'm attempting to use the Superelevation tool on an interchange. I have 4, 1-lane ramps that I need to apply superelevation to. The three issues I have (so far) are:
In the Calculate Superelvation Wizard...
1. In Roadway Type, I don't know what to choose, I'm leading toward Undivided Crowned (center Baseline ) because my assembly (as of right now) is set up as an undivided crowned roadway (with the crown on the west travel lane edge). Which Roadway Type I should choose (for a 1-lane Ramp with different shoulder widths?)
2. Moving on to the the Lanes category doesn't matters. I uncheck symmetric Roadway, hoping I can choose "0" for the number of lanes on the Left, or at least put the lane width down to "0" but can't do either. I uncheck the Symmetric Roadway and it still makes everything symmetric (it acts as though it is still checked?) I only want to show a single 15' lane. (I even tried to use undivided planar, and put both lanes at 7.5'each, but then I still have shoulder issues...)
3. Move to the Shoulder Control. Why doesn't it give me the option to do different shoulder widths? On ramps it is very common (at least in Wisconsin) to have an 8ft shoulder on the right and a 4ft shoulder on the left. How can I type in 2 different shoulder widths.
I need to create an assembly that will give me the volume of a new shoulder along an existing road, as show in this picture.
I can easily make an alignment along my edge of pavement, and match the existing elevations, but I need to hold the cross slope constant AND the shoulder slope constant, and have the bottom of the shoulder slope to a target 2 feet off of my ROW.
I using a data reference/shortcut to properly label an alignment in paperspace. However when I reference the alignment in and apply the labels the aren't the same as the original alignment that I am referencing. Is there a setting where I am supposed to apply a new beginning station.
Also it seems as though the stationing(distance) isn't even matching up 1:1 with the original drawing. For example in the original base drawing my alignment starts at 10+00 with the next PI at 14+76.98, but the stationing on the reference alignment starts at 0+83.33 with the very same PI being labeled as 1+23.08. So the very same distance is 476.98' in the real design and the drawing it's being referenced in, but the stationing of the referenced alignment shows it as 39.75 Units.
I've attached a screen of the beginning of the alignment.

Using Civil 3d2012, Is it possible to change the alignment label style set after the alignment has been created? For example, for an alignment that was created with alignment label set X - change the label set to alignment label set Y? It seems like this should be pretty easy, I must be missing something obvious.
I have a question on Alignment PI's. (Point of Inflection/Intersection)I have an alignment where some PI's have curves, others are merely hard bends.
Is there a way to automatically label the PI's even if they have an associated curve? (I'd like PI, PC and PT)Alternatively, can I only show markers at PI's without curves?
I’m wondering if there is a way to launch alignment grid view/alignment entities (attached) without the need to first launching “alignment”? This dialogue box is quite essential in editing the values of radius, degree of curvature and deflection angle for the selected curve.
Can I inherit the station from one alignment as the begin station for another alignment?
For example. Alignment 1 is 1000 ft long and starts at sta 0+00.
At sta 8+01, Alignment 2 begins and goes off in another direction.
I manually enter 8+01 for begin station Alignment 2. Life is good. Still in the design stage, and customer needs to modify Alignment 1 to avoid something. Now Alignment 2 intersects Alignment 1 at sta 8+15, but same N/E coordinates.
I manually enter 8+15 for begin station Alignment 2.
It would be better if Alignment 2 could inherit the begin station based on the new stationing from Alignment 1.
I'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line. 2. Created new feature line by offsetting outside that feature line by 3.16 ft. 3. From new feature line, grade down 10 feet at 3:1 4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.
I noticed a post a few years ago mentioning this function wasn't available then. Is it still not available? Is there a routine? A lisp? An expression that I can make to put a slope arrow inside every tin in my surface with a % grade?
