AutoCAD Civil 3D :: COM API Section Links Give Erroneous Data?
Sep 27, 2013
Testing in C3D2012, using tutorial drawing "Sections-Grade-Label", selecting 2 sections depicting the existing ground and datum. Note that the datum in the drawing stops correctly where it intersects the ground:
However, when I gather the start/end points for the section links I get points that fall outside the limits of the datum section:
The second item appears to be the daylight point, but the first item is at the edge of the section view with an elevation that makes no sense. At the other side, item 17 is the daylight point and items 18-21 do not appear to be related to anything else in the sectionview, other than #21 which is again at the edge of the sectionview. What could these extra points/links be for? Intersetingly, the same section in C3D2014 returns 1 less point and all points through item 17 are identical, but those following all differ.

I am using Rel 2013 C3D
How do I remove excel data links from my Reference Manager (see attached image). What I have been doing is AutoCad erasing the graphics from my drawing but the link still remains in the xref manager window.

I have an EG and FG data band for sections that works correctly. When i plot sections and it asks me specify surfaces 1 and 2, I choose my EG and FG surfaces appropriately. Then when the section displays the Section 1 and Section 2 are both set to the EG section of that specific sample line. If i change the section view properties manually it works but I'll have to do it individually for each section.
Also, is it necessary to create a FG surface from the corridor or can i get the data band to read from the corridor section itself?

I am creating a data band for Finished Ground. I have created a Top surface from my corridor and have sampled that as well as my original ground. I am trying to add data bands to an existing cross section view. When adding data bands for the cross section, I first go to the Section View Properties, add the data band, in this case, "FG Elevations", In the "Section1" column, I pick the Corridor surface that was sampled.
The data band does not display data. I know the data band works, because I picked the original ground as the "Section1" and it gave me the elevation.
I have noticed that under the "Sections" tab of the Section View Properties, and in the "Type" column, the original ground surface has a different symbol than the corridor surface. I have also noticed that if I have only the "Draw" boxes for the sampled corridor surfaces in the section view checked, nothing is drawn the section view. The corridor surfaces seem like they are not really there. Am I not able to retrieve data band data from a corridor surface?? If this is the case how do I go about making the corridor top surface something I can get data from?

I created some about 20 cross sections for a creek we topo'd and then went to work making the topo itself look presentable. After I was all done with that I noticed my cross sections had lost the surface data and were now just an empty grid.
When I go to edit a cross section's properties in the elevation tab the "Automatic" choice has a minimum and maximum elevation of 0. When I use one of those existing sample lines to create a single cross section the same thing happens, it's not picking up data from the surface. However, when I made a new sample line along the existing alignment it picked up the elevations and created a cross section just fine.
Is there anything I can do besides recreating all the sample lines and cross sections? I'm looking for any other way because I have already labled and put in some extra work on the cross sections and I'm hoping to be able to just recreate what I already did and drop them so it will match the linework I already did.

I have many section views of a road where I want to calculate ground volumes. I have a curb in a section view and I want that Civil showed me just an elevation at the top of the curb and at the top of the road cover. Is it possible to do that? And also distances: I want that Civil just show me a distance from the center of a road to a curb and from a curb to the edge of the road.

I have added intermediate sample lines in my corridor. These sections appear in the section editor and I can make changes to the data. The changes show correctly in the section editor and section view, however, when I plot the cross sections some of these added stations do not show the overrides. They are showing the original assembly group parameters. How do I get all the cross sections to reflect the edited data from the section editor?

My company produces drawing sets that show the same information in multiple places. I.e. an attribute in drawing A is also shown in a different block in drawing B and a different block in drawing C and in a table. This creates problems in that as soon as one piece of information changes, you have to change it in 14 places... and it creates typos. A LOT of typos. So I'm trying to come up with a good solution as to how to link these pieces of information.
I know how to use data links in a table... but is there a way to link block attributes? Also, am I just barking up the wrong tree? Because in my head, you'd have to manually link all of these things for every new drawing, and they can be easily broken.

How to manipulate data links? I want excel tables to come over and use their native excel formatting. I have a heck of a time getting them to look right (text size, font, justification, cell size, etc) and then when I update the link after making changes to the XLS, they get all cattywompus again.
I've never been real strong on text management in CAD; I'm always scaling text and doing poor drafting things like that. So I looked into Tablestyles and things a bit and thought I had it, but not so much.

How does the datalinks handle the links to the excel spreadsheet. I am drawing parcels from legal descriptions and would like to link each parcel to a spreadsheet with all the parcels data via a ID number. Then be able to click on that parcel and see the owner (the link). But my question is: do I have to give each link a new name to correspond with the parcel in order to see each parcel ownership?
And how many datalinks can a drawing handle.

I have lots of section views with some surfaces and pipes. Unfortunately, in a number of section views pipes are not shown in full height because the section view level range is too little. What I am wondering is - is it possible to automatically adjust section level ranges so that they fully include pipe sections? Please see also the image in the attachment.

When i am creating section sheets from multiple section views ,section sheet view port scale changes.I did set it correctly in my template.
For example it changs from 1:150 to 1:150_1
Then in section sheets scetions views are not displaying correctly.
When i change view port scale manually it shows correctly.But it should do to all sheets.
What should I do?
In model spacr multiple section views are showing correctly.

In my section editor my labels show up correctly and in all the locations I want. But then, in my cross section file, I look in my section views and they are completely different. When I try to label more points under the Code Set Styles, they won't even show up on my section views.

I think I just haven't done this in a while and can't find the right setting.
I have existing sections.
I have section views.
I created a corridor.
How do I add the corridor section to my existing cross-section in the section views?
I can view them in the corridor section editor. But I should also be able to add the corridor section to my section views, right?
To plot them, do I NEED to do this through Sheets Sets? I don't have experience with sheet sets yet.
I don't use Civil 3D often enough anymore. Still learning much about the new interface and pulling a design together.

I've got a corridor where the section editor does not show a section that the corridor has created. My frequency is set to 25' with high/low points along curves. At station 22+75, in the model space the corridor shows a section being created (image #2). However, I cannot edit or even see that section in the section editor (image #1). The first screen shot shows the list of stations for the corridor in the editor while the second screenshot shows the model space at the problem station. This is in the middle of a region, so there shouldn't be any issues with other assemblies or regions.
In the section editor, Sta 22+74.91 is listed, skips 22+75, then lists 23+00. I am needing to manually adjust the cross slopes of my lanes. If I view the surface there is a weird dip because at station 22+75 the default slope of my lane is -2%. I cannot edit station 22+75, so I cannot adjust the cross slope of the lanes.
What is causing the section editor to not even recognize a section? How can I edit the cross slope at station 22+75 if the editor doesn't even display that section?

I am having an issue when producing a section view with my corridor. I have a corridor and corridor surface, as well as an existing ground surface. I create a sample line group and sample EG, Corridor Surface, and Material. When I produce a section view I get 4 sections in the view: EG, Corridor Surface(with the corridor surface naming convention), and an additional section simply called "Corridor Surface".
This last section is strange in that it seems to be using the correct assembly, but not targeting the correct features. Also it has grips at all of the vertices which I havent seen before.
And the strangest part, when I click on properties for this section and go to section data, the columns for Description and Data Source are blank.
If there is no data source, then where is this section coming from, and why is it showing up when I did not specify that it be created. This is a real mind boggler to me and makes no sense. Screenshot attached.

My future ground somehow disappeared out of one section view in my group. Under the section tabs I still have my existing ground and pipenetwork but the future ground isn't there. It remains in the other section views. How do I add it back?

I run CS4 on Windows 7. Whenever I boot up, I get an error/prompt that says I have to restart the computer for updating to continue.
I know this has been discussed in many different places here, and I have tried everything everything I can find in them. Sometimes I get a fix, and then the next time updater runs, it's back.
Why can't this well-discussed problem be fixed in an update sometime? Or, perhaps this is my penance for still using CS4.

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.

why am i not allowed to have multiple direct links for a node (junction/outfall)? i have a situation where i want to add the flows to two junctions, one for each side of the property, then add the two junctions to an outfall (overall site). i do not want to model the pipes, just want to add hydro graphs.
my each junction has two direct links coming from two other upstream junctions, and then this junction flows out by a direct link to the overall site outfall (the set of junctions from the other site does the same). i cannot run the model because of the error:
ERROR 134 : Node TOTAL-EAST has more than one DIRECT outlet link or DESIGN pump.
ERROR 134 : Node TOTAL-WEST has more than one DIRECT outlet link or DESIGN pump.

How are people modeling curb inlet bypass flow? When I first got into using SSA, I looked on-line through some AU handouts and blogs etc. I learned to model on-grade inlets using direct bypass links. I would create one that linked upstream and downstream inlets. It appears that hydrodynamic routing is the preferred option for modeling pipe networks with storage nodes, and the direct links don't work due to error 134. It would seem that the logical fix for this is to model all gutter bypass as user defined open channel and create a channel section that matches the road and gutter section. Is that correct? Also, how does the software view a direct link versus open channel?
