AutoCAD Civil 3D :: Earthworks For Assembly Sub-Base
Aug 7, 2013
C3D 2012 SP3 on Win 7 Pro.
I want to generate a report by sample line station that gives me the cut/fill quantities between my assembly(s) sub-base links and the existing ground. I have section sheets cut with sample lines and the EG surface DREF'd. Am I correct in assuming that you need to create the sub-base surface, (for every corridor, I have 18), to be able to get the cut/fill volumes? The corridor is Xref'd into the section cut sheets, so no hope of generating a surface in the cut sheets from the corridor. Can you have the EG surface defined in the Edit Material List and the sub-base as a corridor shape and get the cut/fill volumes? I have tried and I get zeros in the earthworks report.

In Civil 3D 2010, how does one output the volume of earthworks in terms of elevation bands of for example 1.5m?
Using the TIN volume surface, I've already established the total volume of earthworks (cut). However, as I have pointed out earlier, the data is required in terms of elevation bands of 1.5m.

Is it possible to add a base depth to the transition lane assembly? I need to do volumes for my road, (pavement, base) but there is a section with a transition (which only has one depth), so that section is off.

I was trying to create a design template in the Multibody Part environment (MBP) for design cases we use almost every day.We´re relying heavily on semi-finished products (plant construction), so 80% to 90% of our parts are plates, beams, pipes and similar. In most cases we create a welding assembly which has only the semifinished parts which are welded together.
What I expected from the MBP was to be able to preconfigure properties like materials and width, length and height before I create parts which then are placed into the assembly.
Now this doesn't work. So I have created some iLogic code that finds the base dimensions of plates (thickness, length, width) and adds this information to the custom properties so it shows up in the BOM.
This works with a template which I have added to this thread. Now what you do is choose this template for the solid bodies which are plates when you derive your parts after you have finished setting up your MBP.
In the template I have embedded an excel sheet, that searches for a numeric thickness value (discrete) in the "thickness" column.After finding the according entry in the excel sheet it will read out the item number from that column and writes it back into the custom properties.
We're using a PDM system the files get uploaded to and if the PDM system finds a known item number it will automatically connect the documents to the correct item master.
Right now this works only with one material for every template. Additionally I want to be able to get a prompt before the part get's saved, that asks me to define a material based on the data of my style library. How to do that with iLogic code pieces?I will work on this further and will update the thread with new functionality.

I've just started working on a frame generator assembly I was modelling earlier this year; I can't seem to modify the base 3D sketch. The feature which looks like the original 3D sketch is now called the "Reference Skeleton" and I am unable to modify it at all.
I am working on a copy of the original part as I "save as" the whole master assembly when I was last working on the model. I don't know if this would have effected anything.

I thought I created a rail sub assembly.
So I created the rail sub assembly everything looks great in sub assembly composer.
Start a new dwg data reference in the rail alignment, Note the rail alignment type is set to rail.
Create an assembly and under the Construction tab for the assembly the Assembly Type is set to Railway. Attach my custom sub assembly to this assembly.
Created a corridor and I get this error: Something wrong with current subassembly: Operation is not valid due to the current state of the object.
So I delete my sub assembly attach the Civil 3D Rail Single sub assembly. Re run corridor and everything works fine.
So I promote the alignment change type to centerline. Delete the Rail Single sub assembly put my rail sub assembly back. Rerun the corridor and everything works.
So then I undo everything up to the point of promoting the alignment.
Opened the base file changed the alignment type to centerline.
When I tried to synchronize the references I ended up a broken reference with the following error. Invalid reference. Synchronization failed
Not good we already have plan sheets cut.
where in sub assembly composer were do I define the sub assembly to be for Rail?

I need to have a subassembly for a superelevation where the lane and base slope to the left and the bottom of the sub-base will slope to the right. I was using the LanSuperelevationAOR subassembly, which worked fine with my superelevation when the lane, base and sub-base were all sloping the the left, now I need to edit the slope of the sub-base only to slope back to the right at a -2%.

I have a finished corridor, but now I need to add marked points to label a few key grade breaks in my cross sections. When I attempt to add the marked points on some of my sub-assemblies it gives me the error that the sub-assembly is not part of the assembly. I can right click the sub-assemly and choose "Add to Assembly" but when I rebuild the corridor it strips all the sub-assembly data from my assembly and leaves me with essentially a null assembly for the range.

In C3D 2009 you can generate material tables through "Sections" that tell you cumulative volumes for pavement, subbase and base material in separate tables. Separate, meaning you have to generate each table individually. Is there a way to create a materials table that gives me cumulative volumes for these three materials in one generation of a table.
Note: I am currently generating four separate tables (total volume and 3 material tables, 5 min per table) for each of my corridor driveways - I have 82 driveways total = 328 tables

What are some workflows people are using for creating P&P sheets?
I have a project that is 8 miles long so I created all the profile views (18) in one base map drawing using the plan production tool and then they are xrefed into my individual sheets.
I'm finding that doing a save or regen take approx. 30 seconds each time. That seems unusually slow to me.
I asked my reseller about it, and their comment was "We wouldn't recommend that many profile views in one drawing".
I assumed (maybe falsely) that if the plan production tool allowed it, then it should work.

I am trying to xref a base drawing. But everytime I insert the drawing, the scale factor always comes up to be 12. I tried changing it, but it won't let me. I have attached an image of the problem I am getting.

I just tried to create a subgrade surface using the base link. The surface turned out to be wrong because some of the points in the Lane Outside Super Layer Varying Width subassembly are uncoded. Everything I've looked at seems to be programming related (over my head). Do I need to download a composer for 2014? I didn't see one on the list for 2014.

I am just beginning to use the Survey features in Civil3D 2012 to generate a base map. When we use the offsets, we are having issues when we have a negative number: BC ST H-.5. The line will not offset, it just comes in directly on top of the original line. When we use a positive number, it offsets correctly: BC ST H1.4 V.1. Is there a setting somewhere that needs to be changed for it to read the negative numbers?

Succesfully producing a slope analysis exhibit using LIDAR topographic base information with this version of Civil 3D? I have followed the instructions as best I can and have had no luck. I am using a trial version and this is a big factor in whether or not I will ultimately make the purchase.

I am trying to work out a way to set up my Structure Table so that I can show either the Inner Pipe Width OR Headwall Base Width to avoid having Question Marks showing in my Table? Is there a Function in the expressions that equates to a Non-Existent or Null Parameter. Ie.
IF({Inner Structure Width}=???,{Headwall Base Width})
Also, Is there a way to hide Structures from a Table, in particulat, Null Structures?
Currently using Civil 3D 2013 & 2014 SP1

I have a base drawing with all my pipe networks data referenced in. When I xref this drawing into out drawings some of the pipe styles and structure styles are displaying differently than in the base file. Both drawings have same parts lists and styles.

I'm working with a structure profile label style and it seems like the only way to anchor the position of the label is based on offsets from the structure itself... Any way to position the label based on the top of the profile view, so that I could make all of my labels horizontally aligned above the profile view?

There are been a few posts about transitions this week, so here is a simple little sub assembly (provided "As Is") that might work. It was build with Sub Assembly Composer 2014. The way it works it to calculate a number at a station based on a start and end value, a transition type and the station (chainage) value in relationship to the start and end points of the region. It has X transition types: Linear, Parabolic Out (rate of change increases) Parabolic In (rate of change decreases), Reverse parabolic (back to back), Bay Taper (from Caltrans this is a three part transition made of 2 parabolas and a linear section), Cubic Out and Cubic In.
The way it works is you insert the subassembly before a subassembly that you need to transition. You set up the start and end values and the type of transition to make. Then in the following subassembly you reference the value that is returned. For slopes, you'll have to input the values in decimal (4:1 = 0.25)
I've attached a drawing as well that shows a bay taper of a road from 12 to 24 over 120 and a daylight that goes from 1:1 to 4:1 and back around a curve (3 regions)

I need to use LaneInsideSuper for my assembly, but I could not find it in the palettes of Civil 3D 2013.
It does show in the palettes of Civil 3D 2011. I was wondering if there is a way to copy that subassembly from 2011 to 2013?

I'm in the process of building a subassembly in SAC. My goal is to have it transition from one cross section to another over a set length (by using station values). I can set it up so that at a certain station it switches cross sections, but I need to have a gradual change.
I've looked at other posts on here, but they all relate to road cross sections and changing slope (at least from what I saw). Any insight as to the proper way to do this (maybe with Auxiliary points and links)

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.

custom sub-assembly codes,I have gone through the list of codes that is given in the code list.
1. How do I add new code, should I just add with the new index at the end
2. What all things I need to update so correct feature line is picked, etc
3. Any c# example of building a sub-assembly using .net.

A way to edit the stock Sub Assemblies provided by Autodesk?? I noticed they are compiled into a dll, therefore there is not a way to open them as a pkt that I am aware of. My intention is not to get rid of what Autodesk has provided but to add on to them.
Many times I have been asked "This sub assembly is great but can it do this?" of course it is the one thing that particular sub assembly can't do. For instance, the Varying Width sub assembly can't extend the top layer while having the sub base layers go in a negative direction.
