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 had thought this would work with no problem. I know the elevation I need to start an arc at and an elevation at a point along the arc. I drew that portion of the arc and then extended the arc to a line where I need the arc to end. I had expected the arc to extend along it's current grade the way a straight Feature line would. But the end dropped to 0.
I undid the extension, listed the FL arc to get the grade, extended it again and used the Elevation Editor to set the previous grade. But why didn't the extension work? I checked for other FL in the site that might cause this but there were none.
I want to set and Elevation Point (not a PI Point) along a feature line by entering the grade from the previous point. Currently the "Set Elevation Point" command only allows entering an elevations or getting an elevation from the surface. I know I can set an elevation point and then use the "quick elevation editor" to adjust the grade, but I don't want to go through the extra step.
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?
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?
This is the message I get when trying to elevate a featureline to a surface in C3D 2012, SP3. The featurlines (4 of them) lie entirely within subject surface but I am unable to get this command (AeccFeatureElevsFromSurf) to complete correctly with any of them.
The 4 featurelines are at the red arrows, a corridor from the centerline at the green arrow has been created, from which the subject surface was derived and is depicted by the yellow & green contour lines.
I have an existing surface with a steep slope and a feature line for the edge of a proposed walkway. I need a buffer of 25m on either side of the walkway but offsetting doesn't take the grade of the slope into account. How do I grade down the hill from the feature line at 25m to match to the existing surface?
When adding break lines to a surface, a dialog box like appears that asks for weeding factors and supplementing factors. What I would like to know is, how can I change the defaults to reflect the settings needed on my project.
I'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line. 2. Created new feature line by offsetting outside that feature line by 3.16 ft. 3. From new feature line, grade down 10 feet at 3:1 4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.
When we created our fist C3D template in 2007 it was possible to make a grading criteria that targeted a surface at a fixed distance. In other words, the slope was variable. Looking at it again in 2013 it appears it's not possible to creat a criteria like that. Am I missing something? Or was that option removed? .....perhaps because it was too unstable?
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.
I'm trying to create a proposed grade surface using the grading tools. I drew the outline boundaryof the proposed surface as a closed polyline then created a feature line from it and assigned different elevations to it. When I try to select the feature line in order to create the grading, I get "THIS FEATURE OVERLAPS ITSELF AND CANNOT BE GRADED". What could be a possible reason for this?
i have a corridor. the corridor feature line that is supposed to hit the proposed centerline is following my existing grade instead of where the profile is. in other words, the corridor line i need at the centerline when i do "feature lines from corridor" is following my existing grade instead of the top of my road. did i accid. change something? i need it to follow the top centerline of my road. the red arrow is the line i need at the top centerline.
I have a regular AutoCAD line in a profile view and wondered if there is a way of labeling the grade of the line. I'd think I could use and expression to calculate it. But I don't know how to automatically adjust for the vertical exaggeration without having to have a separate expression for all possible situations.
I am wondering why the maximum hydraulic gradline in my profile plot is not matching the maximum hydraulic grade levels reported in the report or excel spread sheets.
When I add features to a surface, they don't keep the feature name. It gets a generic numerical name ie dike:1, dike:2. Is there a way to get the names to hold? How does one keep track of the features/breaklines?
I am working on a 6 mile highway project whose surface file is 85MB big. So, I created a Data Shortcut of this surface and used this for creating profiles. However, at some locations the corridors go below the surface(as per their original profile) which was not intended. So, I need to restrict the surface to follow the corridors but not go beyond it.
I have created feature lines from corridors and tried to add them as breaklines to the surface. But " error adding breakline" error pops up.
Is it because I am trying to add the breaklines to the mirror surface which I created from Data Shortcut ??
Will it be useful if I copy feature lines to original surface file and add these feature lines as breaklines in that file??

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?
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.
