AutoCAD Civil 3D :: Subassembly Feature At Daylight Line
Feb 20, 2013
I have been asked to put a feature (a diversion berm) at the daylight line of a roadway where cut conditions exist off the proposed shoulder. Because of the length of the project, it would be useful if this could be done automatically as part of the corridor, rather than creating a feature line from the daylight line and grading it separately.
Is there a way to continue an assembly past the initial daylight line and make it conditional to cut situations?

Why I can't mirror the Daylight Inside ROW Subassembly? For some reason I can only place it on the right side of my assembly and in the subassembly properties there is no option to flip it to the left. In the Modify Subassembly section when it's selected the mirror option is greyed out.
What I am trying to accomplish seems simple enough:
I have a utility easement in a drainage ditch that is 30' wide with a sewer line designed down the center, we need a very simple 10' access road on the uphill side of sewer line with 4:1 Cut/Fill slopes on either side when possible, however when the 4:1 won't catch within the easement I need it to daylight within.
At first glance the Daylight Inside ROW seems to be the appropriate subassembly for this instance but I can't get it on the left side of my road.Is there a way to set up this parameter with a different subassembly because I can get other subassemblies on the either side just fine, for example, the Cut Slope Layout Mode subaasembly works but when I build my corridor with it the slopes tie outside of the easement in several locations.

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.

My corridor Feature Lines for Daylight Jump across in different areas (see attached PDF)
when I look at it in 3d it looks ok but the plan view the jumped lines show up.

So simple little retaining wall subassembly created in the SAC. When i extract multiple feature lines from a corridor using this subassembly, all the feature lines assume the elevation of the first link i selected. So if i first click on 'RW_Hinge" all successive feature lines will show up with the same elevations as "RW_Hinge". if i erase all the feature lines the select a different link say "RW_Top" then they all go to "RW_Top".

I have a list of offset distance from centerline on both sildes (left and right). I want to use this to create a polyline that represents the daylight. these offsets are taken from an old hardcopy drawings of cross-sections. is there any way to draw this polyline that follows the alignment?
file can be .txt or .csv

I have problem with corridor surface boundary , in curve boundary line is jumping on daylight fill , but i have created surface on wearing layer ,also when i am adding boundary there is only 3 types of adding , corridor extends , polygon and interactively , photo attached.
I am using Civil 3D 2014

I needed to remove a feature line that I used as a break line when creating a surface. When I removed the feature line from the definition of the surface, the grading did not change. It appears the points created by the feature line remain which is why grading didn't change. The only work around was to delete these points.
I noticed the same thing happens when I removed the surface boundary and inserted a new boundary. why these points remain and how to remove when I delete boundary and feature line from surface?

When I use ImportSubassembly API to import my subassembly created by Autodesk Subassembly Composer into my civil project, it reports error-"eFilerError".
the code like this:
atcFile = @"D:9f92eaa4ef514ac982518852e1169932.atc";
itemId = "ab660722-c69d-4ade-b373-0e9f99c94e55";
SubassemblyCollection subassemblyCollection = cDoc.SubassemblyCollection;
ObjectId subassemblyId = subassemblyCollection.ImportSubassembly("TestSubassembly", atcFile, itemId, this.doc.Editor.GetPoint("Select import subAssembly location").Value);
However, it is OK if to import subassembly provided by Cilvil 3D.

Is there any way to project feature lines into a profile when the plan view is xref'd? I have my plan view "existing topo" with all existing features/Figures and a existing surface.
My profile is a separate dwg with plan view xref'd and surface a data shortcut. Of course there are feature lines and Survey Figures in the existing top I want to project into the profile, but can't because it is an xref. Besides copying .

C3D 2012. I am trying to get the distance from the start of a featrue line to a selected point. My object is "FLobj" and my Point is PT1. I am using the method Get2dDistanceAtPoint. This is the line of code.
(vlax-invoke-method FLObj 'Get2DDistanceAtPoint pt1 'pDistance)
I keep getting "too many actual parameters".

I am wanting to add the name of my feature line to a label style. I am trying to create a label style that will show Lot Number and Area. I know i can create parcels, but i dont want to! I have also created a map table that can do exactly what i want on polylines, but will not work on an xref. Labelling featurelines does work in xrefs.
how to add the name into a label style?

I am building a surface and have back of curb, curb face, and curb flowline going around a curve. I cannot create the lines with the usual pline as they will cross due to poor field collect. I created the curbs with multiple arcs. I was then going to change them into Feature Lines and am wondering if I can then use them as breaklines in a surface.

We have cooridors with features such as terrace drains and flowlines, but we cant seem to get the linetypes to show up correctly. For example a flow line should have arrows but it shows up without the linetype and looks continuous.

I am building a corridor with the right side of the pavement fitting to the existing surface.The subassembly used to link the edge of pavement to the existing ground is LinkSlopeToSurface.
On the corridor created, the feature line (code P2) of the corridor surface (top) starts from the station 0+025, instead of 0+000.
I was wondering why there is no feature line P2 for station range 0+000 to 0+025? Does that mean the linkage to the existing ground surface not exist for the slope defined in the subassembly?

We are running Civil3d 2012. When converting a line or 3d poly to feature line, or just creating one it adds elevation points where it crosses surface breaklines even if you do not assign elevations. We want the feature to just have 2 elevations. The beginning and end. Is this a bug? Or is there another setting somewhere?

I created a label for retaining wall that takes the z value from the start and end of a feature line. Works great except that it isn't dynamic. I have created the feature line in a grading sheet where the surface is data shortcut into it and I'm just using grips to make sure the ends are on the bottom and top of the retaining wall. Is there any way to dynamically pin/tie the feature line to a surface that has been data shortcut?

AutoCAD C3D 2012 has been crashing nonstop over the past 3 days on me whenever I try to "Create a Feature Line from Object". I know that it is a localized problem as a co-worker has been in the same drawing and done grading work without any problems. The error has occurred in multiple drawings.

is there a way to draw a line in the profile view and create that line into a feature line? and if there is can i project that line into the plan? i know that you can make a feature line in the plan and project that feature line into a profile view, just wondering if you could basicly do the reverse. i don't want to make a coridor.

I Created a Feature Line from Objects (a polyline). I added it to Site 1, gave it a name, layer. Do I Assign elevations during creation (conversion options)?
I set the Elevation to 8.5 (NOT From surface)
Then I go to
Modify Feature Line -
Elevation Editor.
Why are the elevations locked? I want to set them.

I often use feature lines for parking lots and ponds. They're great when they work, but they drive me NUTS when they don't - which is a lot of the time. For parking lots and ponds, my feature lines usually close back on themselves. That's when I have trouble breaking the feature line. When I use BREAKFEATURE, I choose two points and this should, in theory, leave a gap in the feature line between those two points. That's not what happens. I end up with a huge gap between the first point I picked and a vertex point 5 or 6 vertices away. It doesn't matter where I pick the breaking points.
I've also tried TRIMFEATURES. I draw lines across the feature line where I would have chosen the breaking points. But the portion that I want to remove is the portion that always remains. It doesn't matter where I select the feature line to be trimmed (inside or outside of the cutting edges).
I think there may something wrong with the feature line itself. Sometimes, if I erase the original and draw a new one, it will trim just fine. But that's such a headache, and it doesn't always work. If I knew what was causing the feature lines to go squirrely, I would aviod it. Unfortunately, it seems like breathing the wrong way can screw up a feature line.

I was wondering if there is a way that I can take an existing grade surface and apply a designed pond surface.
Right now I have the pond as a set of 3d Polylines in the proper geometry.
I want to place the pond into this surface and cut/fill at a 3:1 from that pond to the existing surface.

I have a problem about creating feature line. When I want to create feature line between two red points, another point come into being by itself (blue point). If you look at the file I have attached, you will understand well what I want to express. I cant make any changes on this point. I cant delete, modify etc.

I have a complex grading situation with a sewer near a drainage channel. Long story short.... I need to somehow look at my alignment section by section and try to establish a feature line that will represent my proposed top of slope. There are a ton of different constraints that I will not go into. My ultimate need is the ability to establish a feature line or 3d pline from the section view. I know that this is somehow possible via corridors. Im working with just an aligment and cross sections at every 25 feet. Is this possible?

We are working on a road widening scheme where one edge of the road is retained as far as possible while other edge being widened. I like to design a retained channel line by extending the cross fall between the existing center line and the exiting channel line on to the design one.
It is possible in civil 3d to extend the gradient between two feature lines at some offset from reference feature line?

I've been researching the options to deal with tessellation of my corridor. I see the option to extract feature lines from the corridor and to maintain a dynamic link.
I've now found a link in the docs for converting tessellated lines to arcs. Can I use this command with a dynamically linked FL? And will it maintain the dynamic link? [URL] ....
