AutoCAD Civil 3D :: Creating Feature Line Between Two Red Points
Mar 26, 2012
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 am drawing a few feature lines within my surface and it is creating split points.....not even sure how they are created and how do I get rid of them....is there a way? I read a little about them and what I have read so far indicates that it is a point where two feature lines cross? I don't have another feature line created anywhere near this one.
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?
Given a feature line/polyline(FL/PL) and a series of points directly on the FL/PL, how can you assign the elevations of the points to the vertices of the FL/PL?
In order to create a swale, I created a feature line representing the bottom of the swale and graded up to an existing surface around its outer perimeter. The slope pattern looks ok when it initially generates the grading. I need to grip and drag certain points along the feature line in order to bring the top of slope lines of the swale close to the bottom of slope lines of an adjacent berm. As soon as I grip and drag the feature line, the slope pattern lines go awry. Instead of a short line then a long line, then short line, etc., the lines are all the same length. It actually appears as if short and long lines are overlapping each other.
I would like to get more advanced and creative with my creations. basically when i think AutoCAD i think lines so a nice short program to get started with is to create a line between two point (or simular). The tutorials online are wofel in learning the basics such as this is, need few starters on how to achieve this
Is there a way to link feature lines to points? If I have a series of points and I've joined them with a feature line; I want the feature line to update automatically if I adjust a point elevation.
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.
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.
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?
I'm having troubles using the create points on grid command. When I run the command, I keep getting asked to type in the point description for each point. I have about 5000 points to create.
Is there a way to set a description for all the points, so I don't have to do this manually?
I have a grid survey of points and I've entered these points into Civil 3D. Now what I want to do is use these points to create a surface so that I can create a slope analysis of the surveyed area. My problem is that I can't get the points into a point group.
I have a generic grid (15 x 15) of points set up and I've only used a portion of them (defined by the dimensions of the site). So I want to create a surface that includes all of the points that aren't set at an elevation of 0.
I created a Description Key called "EP" and it will land in a "S-PTS-EP" layer automatically.
I then created a Description Key called "NEW EP* " and created it to land in a new layer called "S-PTS-EP-NEW". But, when I manually create a point called "NEW EP" or "NEW EP BC", it does not land in the "S-PTS-EP-NEW" layer.
Is there some switch I need to turn on or is my description not complying with some naming convention?
I encountered a problem while creating contours from the points. what actually is the problem with the points or tell the steps once again that would be great. I'm attaching the points file.
I have a number of 3D polylines that where exported from SDF previously created. They have numerous vertices, each one with a given elevation.
How can I create/highlight the higher and/or lower point in each 3D polyline??
A different solution would be automatically breaking these polylines in slope changing points (i.e. high or low points).
I understand that i can create points according to slope or elevation, but it has to be done manually, each poly at a time, and by tipping numeric values that i am sure that a powerfull software (as Civil 3D is) is able to calculate using the drawing information.
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 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?
