AutoCAD Civil 3D :: Replacing Lines Representing Ditches Into Actual Ditches
Oct 22, 2012
I am trying to model the hydrology of a construction site using AutoCAD drawings. All of the lines have elevation data which I can use to create a DEM of the site and model the waterflow. All of the lines except for the lines representing ditches. The ditches are labeled as having elevations of zero feet and are not really ditches at all... just lines.
Naturally this screws up the model quite a bit. I am hoping to replace the lines with ditches that have defined elevations, cross-sections and slopes, but I don't know how to go about doing that.
I can design a network of open ditches and pipes in Storm and Sanitary Analyzes to handle the flows required but when I export them back into Civil 3D the open ditches disappears. How do I add open ditches to the pipe network?
I have to represent a road section with limits of houses or any interference on field. All of thees interferences are poly lines, 3dpoly, lines, etc. Is it possible to have a little mark or something like this in a road section, it will work for me a lot for represent the houses in my sections.
I am start work in civil 3d 2009, I have a project started in LDD2009 and am trying to migrate to civil 3d 2009. I have imported the points, tin, and contours but cannot figure how to create an actual EG surface. Can some on etell me how to create and actual EG surface using tthe tin and points.
When i am laying out a storm sewer pipe network with structure sizes that vary i notice no matter what the structure size it always appears the same size in plan view. How to fix this or is this one of those things that its always shown the same size for all and only different in profile view.
Problem with command from Home tab - Draw panel - Curves drop-down - Create Curves Between Two Lines OR Create Curve on Two Lines.
If you select the Degree option, it draws a zero length curve when you type in a valid number for degree of curve. I have tried entering it in decimal format and as ##d##'. NOTHING WORKS!
I accidentally created 2 levels representing the third floor. This is confusing and no doubt will lead to unexpected behavior when the model gets more complex. How can I delete a level?
What I want to do is create a material that has both a brick surface pattern and an underlying solid grey surface pattern. Is this possible? The reason for this is, to represent different colors of brick in the same plane.
It's easy enough to move the map marker for a single image. But I can't find a way to move the marker when multiple images are represented by the marker (thereby changing the location information for all the images). What should I be doing?
I have a bunch of feature lines defining some building footprints and what not. They are on different layers for each possible design I am considering. Whenever I freeze any of the feature lines, they all turn off, eventhough they are on different layers? What is the problem?

I'm trying to create sample lines at sta. 0+58, 1+08, 1+58, 2+08......................
My alignment begins at 0+00.
In the Create Sample Lines - By Station Range I set the From Alignment Start?end both to false and set the start and end stations as 0+58 and 20+58 respectively. The 0+58 sample line plots at 0+58 but the rest of the sample lines plot at even 50' stations (1+00, 1+50...).
what i did wrong, but suddenly lines with different colors are all displayed as gray. I could attach the file, but the problem is really simple. I have three lines and under properties i can clearly see that one should be red, the other should be color 250 and the third 253, but visually all the lines look gray (i believe they look 253 to be exact).
If i draw new lines, the colors act normally, but the old lines are all gray.
I have built a alingment, corridor, and surface of a driveway but I have a few holes in my surface. I tried to add lines to my TIN surface and some filled in properly but others would not and I had TIN lines that crossed (actually they are 4 different lines that meet at on point). Why does this happen and how can I fix it?
I created a profile showing original ground and included superimposed profiles and an offset of the og line. Now when I open the drawing, the profile lines are gone. The grid is there, all of the profiles are listed under the alignment but they are not showing up. All of the styles are on and I've turned all layers on. I've tried to regain all and recover the drawing but the profile lines are not showing in the grid.
So here's an odd one (at least I think it's odd ): I have a drawing that it utilizing feature lines which are projected to the cross sections to display R.O.W., easements, etc. However, every now and then (there doesn't appear to be any similar operation that causes this) the feature lines will change their location, in this case they typically seem to move north and east about 200'. I can't deuplicate the problem...it just seems to happen on its own.
I have created a feature line from a survey which will be the inside shld of my new road design. I have created the feature line using my design elevations but need to add a PI and Elevation at a specific Northing. When I try to edit I can only seem to find the chainage and elevation but I also need to know the northings and eastings so I know where to insert my PI. I would like to just edit the table since I can't seem to figure out how to insert the PI. (I am new to C3D and still learning...) My final product will be a road with 2% crossfall and I intend to use offeset and grading features to accomplish my final design. How I make this edit...
Putting in a simple berm crest, and the triangles skip right over a certain section. Swap edge does nothing and adding points seems to make things worse. I have been able to fix this problem before, but only by deleting my surface and then putting all the pieces back in at once. Then it's perfect.
I think part of the problem may be that the "Contour help" I put in at the blue major contours is screwing things up.I have had the same issue when putting in down-slope channels as well.
I have a client that just started using C3D 2010. When I sent him a topographic survey with contour lines (I am also using C3D 2010) he called me and asked if there was a way to select an individual contour line and have it display the elevation in the 'properties' dialog box. I have not been able to find an answer for him.
I'm currently using the Autocad Civil 3D 2014 on daily basis for urban infrastructure design. When using Autocad Civil 3D 2013, I always would create feature lines from corridors and then export this file to a ACAD 2007 version, which would read the feature lines as 3D polys. The company's topographer could then use this file to make his markings on the field very easily.
Now, when I do the same process using Autocad Civil 3D 2014, the ACAD 2007 file won't present the feature lines as 3D polys, but as 2D polys. This presents a major inconvenient, because I now have to export the file to ACAD 2007, open it in Autocad Civil 3D 2013, rebuild the surface from the design contours and create a feature line from the design surface; export the surface AGAIN to ACAD 2007 and FINALLY I'll get the 3D poly my topographer can read.
I need to make a map of a subdivision with all lot dimensions. I see how we can label all the lines of a lot by picking the parcel label, but it only allows one at a time.
I have a curb return that was drawn as a fillet and I added two points at the PC and PT. Is there a way to create a feature line out of this with the two points associated so that it will interperlate between those 2 points?
Over the past 6 months we have had the feature lines just up and disappear from the drawing for no reason. They were not erased. They just went away for some reason but the surface created from them was still there.
