AutoCAD Civil 3D :: Project Crossing Pipe Onto Road Center Line
Apr 24, 2012
I need to project a crossing pipe onto a road centerline. I have water running down one side of the road 7' off the centerline of the road and sewer running down the other 8' off the centerline. There is storm drain running perpendicular across the road.
The sewer and the water are projected onto the centerline of road profile. When I draw the crossing pipes in that profile view and change the override, because it does not cross the centerline, it disappears from the profile view. How can I accurately show the crossing at the proper invert of the respective crossing without drawing the ellipses manually?

I have problem with medians ( Both MedianRaisedWithCrown and MedianRaisedConstantSlope) when crossing center line ( i.e whole median has to cross the center line).
I have median that goes along the centerline and it has to move to left completely ( whole median is on left side of the centerline) to cater for left turn. I tried with MedianRaisedWithCrown and MedianRaisedConstantSlope but it did not workout for me.
I used alignment ( for cl ) and offset alignments for median edge and etw. I have problem when the median edge ( offset alignment ) cross the center line and continues. I can see etw and median feature line shifts.

I have a storm crossing shown on a road profile, and the ellipse that represents the storm pipe is only showing part of the inner wall (I've attached an image). This pipe is skewed slightly, but the entire pipe crosses the road alignment, and this should not make any difference.
Also, is there any way, yet, (I'm using C3D 2011) to have the label show not only the pipe name, but also the invert where the pipe crosses the road alignment, and remain dynamic,? In other words, without having to edit the label text, and lose the dynamic capability. Land Desktop would do this, but it was not dynamic, of course.

i've got proposed stormwater pipes crossing existing utility pipes. my proposed stormwater pipes run parallel to but offset from my road centerline alignment. i want to show the existing utility pipe as an oval where it crosses my stormwater pipe. i can get the utility to show up in the profile at the centerline alignment of my road but not at the actual point where the pipes cross. is there a way to show this?

I have this intersection and I want to make a roundabout there. The first step is to make two center lines of the roads. How can I make these centre lines perfectly aligned? The lines that you see in the attachment are freehand made.

I created this label for my pipe crossing. I want to be able to start the vertical line at the invert, and be able to move the text up and down and have the line adjust.
Currently my dragged state has the arrow head size as 0 and visibility as false, since it starts the leader at the centerline of the pipe. But without using the leader, I cannot adjust the vertical line dynamically.

Problems with masked crossing pipe in the profile view? So basically I want to show a manhole with three pipes attached in the profile view and I use style override for pipes in a profile view to show crossing pipe, but crossing pipe gets masked with "Enable part masking" option in the Structure style. So I either can show crossing pipe and projected pipes drafted to center of the structure, or I can see only projected pipes drafted to the structure outer walls, but cannot see crossing pipe.
I would like to see projected (incoming) pipes drafted to the structure outer wall, and crossing pipes. Is that possible? See figure attached.

Is it possible to label a pipe crossing offset in section view dynamically? I see there are options to label start offset and end offset, but not at the actual crossing.

I have a typical storm sewer pipe network in a drawing by itself with an alignment. I data referenced both of these into another drawing. I draw the pipe network in the profile view I created and the pipes that run with the road show up fine. Every once in awhile there is a lateral storm sewer pipe that runs across the road. When I draw these in the profile view they show up, but, only the pipes that are skewed to the alignment show up. If the pipe is perfectly perpendicular to the alignment it does not show up. I have two styles setup. One main one that shows the inner and outer pipe walls and another one for overrides for the crossing pipes and that stlye has crossing pipe walls turned on.
Why is it though only the skewed pipes show up as ellipses in my profile view but the perpendicular pipes do not?

I have a drawing with a couple of profiles and some pipe networks. One alignment is collinear with the pipe network and another crosses the networks. I want to show the pipe crossing as well as the longitudinal on it companion alignment. If I set the profile setting for the pipe display to show the pipes crossing I don't get the longitudinal and if I try to assign the different style to the crossing pipes the plan view disappears. So, how should I set my styles to get a crossing pipe and a longitudinal in the same file?

Noticed this in R2013? Not bothering to check with 2014 yet as I don't really use it.I have three vports. TL is Profile view, TR is SV and other is 3d.
There seems to be slight difference between the pipes in the profile/sections compared with the Structure pipe crossing.
All styles are set for External walls, when swapped to internal this is still incorrect. All pipes are same size & part and are Horizontal. Sections / alignment is taken along centre of pipework.

If I have a Crescent Road (P - shape) where the Alignment returns to itself, when i draw pipe network parts in profile, the pipe network gets drawn wrong, ie. the tie-in structure at the intersection is drawn at the wrong station.
My understanding is that the structures will get drawn at the station closest perpendicularly to the alignment, so the structure is going to the end station as opposed to the beginning simply because the end segment of the alignment is closer.
Is there any way to make a structure use a different perpendicular station (without shortening the alignment)?I don't want to move alignment or structure.

I made an alignment of road, inserted with sample line, then i made a profile. But on the sample line on profile, there is not a data of height and lenght of profile. How to get those data in road profile. I can manually draw that, but i think there is an easier way?

I am looking to draw my pipe with a thicker appearance than the typical line of width "0". Our storm pipes are usually drawn with this so as to stand out from other utilities. If the pipe is represented by a polyline, I have usually adjusted the "Width" or "Global Width" value to my liking. With pipe objects, it seems more complicated. I have searched the settings, and the closest thing that I could find was the Lineweight property, but that appears to have no effect on the line thickness in the CAD drawing.
Do I need to tweak a plot setting? Make a new linetype altogether?

I am using VB.net to do a selectionset for any object crossing a line. I can pass 2 points fo the line(start and end )
In vb6I use.
Select acSelectionSetCrossing, vStartWithin, vEndWithin, varDataType, varDataFilter
What I should use in .Net?
I tried using objEd.SelectCrossingWindow(StartPoint, EndPoint, objFilter)
it returns wrong result.

I have a Storm pipe network for a subdivision. All of the pipe are on the same layer, using the pipe style. For some reason, only 1 of 68 pipes will display through my viewports. All of the layers within the pipe style are thawed in my viewports, as well as the layer the pipes themselves are on.
Further, when I go back to an archived file from a few days ago, all the pipes are also on the same layers and styles, and all pipes display as they should through all viewports. There seems to be no rhyme or reason for this. I am not sure what could have changed as I didn't knowing adjust anything with the pipe networks since archiving a few days ago

We have a big piping job coming up and as Civil3d still lacks some of the labelling abilities we want in the profile view bands. I am updating some old vba that adds a profile line of the invert of a pipe network to a profile view effectively tracing along the bottom of the network like I know a lot of people do by hand.
My original code works on assuming that the start and end structure are at the start and end of the alignment in the revised code I want to allow for situations where this is not the case.
Leading to my question is there and easy way to find the distance a profile view part is drawn along the parent alignment or do I have look at writing my own function possibly extracting a polyline from the alignment and finding the distance using intersectionwith and distancefrom functions with the structure.

I created a 2d drawing of a river I am building and constructed a centerline. I already have a surface of the existing ground created from which i created an alignment of the centerline and created a profile showing the existing grade along the centerline. Then I created another alignment on the same profile which shows the bottom of my river that I want. I now want to calculate the cut and fill of my project but don't know how. Is there a way I can create a surface of my river from my profile? Or what process do I follow to apply my centerline profile to my 2d river.

Is there a way to project just one feature line (or anything appropiate...polyline, 3d poly etc) into the sections group or profiles ?
The thing is that Projection tool, labels everything that's a Block, Point, 3d poly ...etc to the sections group.
And it puts all labels in the same layer.
My project theme requires to project forest limit on every section. This is appearing on the survey as a polyline along the road. Civil Engineer / Infrastructure of metropolitan transports [URL]

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 have two pipe networks and two profile views, one for storm and another for sanitary. I would like to show the crossing pipes on each of the profile views. When I select the profile view, add a pipe and change the style to crossing the style is change to crossing on the other profile view (ex. on sanitary profile view I set storm pipe 3 to crossing style, on the storm profile pipe 3 changes to crossing style and does not display). Isn't there a way to display the styles for pipes different in each profile view?

It can be done using the LaneFromTaperedMedian subassembly, and that there is a webcast explaining it. I have checked with Autodesk, and the webcast is no longer available. Any detailed instructions as to how to accomplish this. I'll attach an image of my median.

I have a drawing with 3D polylines that will be used to build a surface but many of them cross each other.
I would like to extract the vertices of these polylines and use this information to build the surface but can't figure out an easy way to do this.
I have tried the Points at Vertices Automatic which is ok but as there are 300 or so 3D polylines this will get very tedious very quickly - is there a better/quicker way to do this?

We are starting a new job, and looking how to setup our drawings. We have a long corridor that we are upgrading, and along this corridor, we have various water course passing through. We are replacing the existing culverts. They are large circular culverts. How do we show the culverts on our model? Do I create a short pipe network for each culvert crossing? And also, how do I daylight to the outside of the culvert as the corridor crosses over it?

Dealing with an old topo. Building a surface from a point group of points in the drawing, and 2D polyline being used as proximity breaklines.
Here is my list of events after I rebuild the surface:
So I went to use the 'Resolve Crossing breaklines' tool, and here's what that looked like:
So are there or aren't there?
When I use the 'Zoom to' feature, it takes me to the midpoint of a TIN line on a breakline, with no other objects around. Crossing window selection: only the surface and one polyline. I found one crossing breakline just by accident, not from either of these tools. After I fixed it it didn't change anything. I even deleted all the breaklines from the surface and added them again, closed drawing and reopened, no change.

I have recently started working with civil3d 2012 & 2013 so go easy one me...
How can i check the elevations of 2 alignments that cross (junction)?
The localization team in Israel has added a utility that marks the junction on the profile view with a red flag and 2 marker lines, one for the existing ground and one for the elevation of the crossing alignments. The flag is not a civil3d entity, it's not dynamic and needs to be reset after each change.
Any better way of checking the elevations? (including adding a block or anything to the profile to show the other alignment name and elevation).

Is there a way to show a corridor assembly in a crossing profile in c3d 2012? I have a underground duct bank that I have modeled using a simple corridor. Now I want to have the duct bank assembly show up in another profile that crosses the ductbank corridror. I can't really create a surface fom the corridor since the duct bank a closed polygon. BTW, The subassembly for the duct bank was created from a polygon, if that is any useful info.
