AutoCAD Civil 3D :: Daylight Lines Intersect At Turn Segments
Jun 20, 2012
I've created a corridor with a Cul-de-sac. The problem is that the daylight lines targeted to the existing ground intersect at turn segments:
which results in defects of corridor surface:
I wonder if there's a way to overcome this.

Our survey crew would like to upload a dxf file into their data collector in order to stake out linework such as curb & gutter with elevation. They have given up on using stakeout points as a standard procedure long before I arrived (being the cad guy I just figured everyone used points for stakeout) and up to now they would just use the 2-d linework and manually calc elev on their own. From what I understand our RLS didn't "trust" the data collector to use elevation for staking. Now that we finally talked our RLS into "trusting" the data collector as far as using elevation for staking we are running into problems with our feature lines when exporting to a dxf file. As you may or may not know when exporting to a dxf file it explodes our feature lines into lines, p-line, and arcs. Feature lines that have different elev & no curves turn into regular line segments and they still have the correct elev on each end vertex. Great. Feature lines that had the same elev for all vertex turn into a polyline with no elev or a whacked out elev. Featurelines that had a radius turn into polylines and/or arcs (I don't know what it's using to determine this) but either way the elev is zero or whacked out once again. No good!
So, using a dxf file in their data collector to stakeout linework with elevation? If, so what is your procedure?
Furthermore I find it absolutely ridiculous that... oh never mind, it does no good to complain about the complete lack of transparency between C3D, surveyors, and surveying equipment.I have tested the dxf file with both C3D 2011 & 2012. I have not tried it with 2013, maybe that has changed? Our survey crew is using a Tsc2 data collector.

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.

Create Parcel Segments using the Slide Angle Create command
Create a Feature Line in the same Site that bisects any/all of the Slide Angle Create Segments
Save, close and reopen the drawing
Parcel Segments now terminate at the intersection of the FL
Not sure if this is as designed, and I don't recall this behavior in 2007. We have used FLs to assign elevations to Parcel Segments in 2007, looks like this is no longer possible.

I'm having a random issue with the daylight ties lopes not tieing to the EG surface at all stations in the Corridor Section Editor. Some stations daylight fine. In plan view the daylight lines vary left & right as expected but don't display at all in Section Editor.
Some background info:2012 Civil 3D SP1 / 64 bit / WIN7Simple corridor used1 alignmentSame fg profileSame drefd EG surface (set all targets for daylight LT/RT)Only one assembly applied to entire corridor Attached are 2 captions of the issue I'm having which each have a cut & fill occurrence as well as a caption of the entire align. & corridor. I did try deleting corridor & recreating and even recreated a simpler assembly and still have the daylight issue in same areas of corridor.

With all of you fine teachers, I have the know-how to get the start and end values of a line.
Do you think there is a way to get a point returned that represents the true intersection of the two lines, without having to involke a user defined "getpoint" function using "intersect" osnap?

I have a problem while executing intersectwith between polylines and lines
the polyline execute intersectwith method referencing a line object with expandboth parameter value but sometimes , the intersection is not found
when using expandthis or expandargument values, I have no problems
I'am using VS2012 express and Autocad 2014
the attached project containt :
an image (result;png) showing my result
a dwg file (dessin3.dwg) , it is my test file
the source code for testing , (test" command)
it find all polylines and all lines in the drawing , compute the intersections between each couple and draw a dbpoint on each

I must have hit some type of command on my keyboard but now my anchor points and intersect guides have disappeared that would normally appear when I roll my mouse over the anchor point or the intersecting paths. I have hit Ctrl + H as well as went to the menu manually and my edges are showing. How do I turn back on this ability to see my anchor points and intersecting lines guide in Illustrator?
I run on Adobe Illustrator CS5

I know I should know this, but can't seem to get it to work.
I have two ~parallel feature lines about 250' apart. I grade the Easterly Ft Line going west at a +1.5%, and I grade the Westerly Ft Line going east at a -2.00:1 slope.
I know C3D doesnt have a tool to intersect them, I must use the intermediate surface approach.
What I did was grade one, create 'Paste Surface 1' then grade the other, create 'Paste Surface 2' and then I created Surface 3 and pasted 'Paste Surface 1' and 'Paste Surface 2' into Surface 3.
Throughout I used 'Grade to Distance'
Surface 3 doesn't come out correctly.

I'm a bit perpplexed about a very simple grading scenario: intersect the daylighting of two gradings as shown in the screen capture. I would like a solution that is dynamic to changes in either of the 2 gradings.
The intended result is in the 3D PDF.

I was trying for an option with wipeout mask.
Is there any option with wipeout to turn the continuous lines into dotted lines instead of hiding the object? I have been working on one staircase block, i want to show half block as a dotted lines.. is there any way to do that without going in to the block edit and change? thats why am looking for wipeout mask option.

I'm using the Intersect With method with two pipes. The Intersect With method doesn't appear to work with curved pipes if the pipes do not cross. If they don't cross the method works, but if they don't then it doesn't find the intersect points properly. This appears to be an issue with Civil 3D 2010 to 2012 API.
[URL]........
In the screen cast image the pipe on the right finds the intersection point with the straight pipe on the left, but not the curved pipe that is in the middle. I've had poor results trying to put in support requests for API related issues.
For Civil 3D 2010 here's the code that isn't working:
oPoints = new Point3dCollection();
Pipe oLateral = (Pipe)lateralObjId.GetObject(OpenMode.ForRead);
Pipe oMain = (Pipe)mainObjId.GetObject(OpenMode.ForRead);
oLateral.IntersectWith(oMain, Intersect.ExtendThis, oPoints, 0, 0);

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 wonder is it possible to have a daylight (or other function) that can give a different slope for datum and for the top. This would be useful for if you have different rules (e.g. because of geotech) with regard to temporary and permanent batter slopes.

Is it possible to make a bench right before the daylight line meets the top surface (Original Ground)?
The Road prism is a tylical shape that has a u-shaped ditch on one side. The daylight line from the outside edge of the ditch follows a series of comlicated benches at set elevations and then terminates at OG with no trouble but I'm trying to get an additional bench to be generated before OG (see attached + yellow lines).
how to add this extera bench?

I'm modeling a simple corridor (12' lane 2%, 6' shoulder 6%, 4:1 to match EG). I used the "LinkSlopeToSurface" subassembly for the 4:1 to match the EG. Unfortunately our EG isn't always wide enough for the 4:1 slope to match it somewhere.
Is there an assembly that would use 4:1 as a standard daylight slope, but where necessary adjust the slope, max. 3.5:1, to match EG surface?

I am working on a project where some of the corridors require different daylight slopes. I need to transition between a region with 2:1 slope to a 10:1 slope. My local civ3d support said something about using grading tools to achive that.
What I understood was that my assemblies should not have any daylight sub-assembly and that i should grade the corridor and than add a transition zone between the different gradings. Did I understand correctly?

is there a way to extract a 3D poly line where two surfaces intersect each other.
i have ground surface and i have dam surface. they would like to show the filler material in the cross section graph.. so i copied then raised the surface the required depth.
so now the surface and side slope of the dam intersect. and i would like to trim the filler material surface to be in line with the dam.
