AutoCAD Civil 3D :: Dimension Along Polyline
Jun 21, 2012
I want to dimension along a curvy polyline. I don't want to station it like a centerline. It is for pavement marking dimensions in a curvy road and I want to show the total length of turn lane lines while they go through an s-surve. I could draw the dimensions manually and have in the past. For the contractor, I would simply station and offset it, but it makes it easier for the reviewer to see total turn lane, taper and lane shift lengths, rather than having to calculate them from station and offset callouts.

I have written a function to draw polyline (with dimensions), by getting input points from user.
[URL]
Now, I have to give a provision for user to edit the dimension of each side.
I have also written a function in which if the user double click on the dimension, a dialog box will appear and prompts for new distance.
My problem is now writing the program to change the polyline segment based on the new distance value.

Any way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.

Recently my company has changed the standards to label existing utilities with text right above the utilitie lines without leaders. I would like to do automate this process somehow using attributes or something similar to that. I have attached a screen shot of how I would like it to look. The objective is to speed up the labeling process.

I have a point cloud that i want to snap a boundry around its outer limit. Is there some way to do this automaticly? I tried creating a surface and using the maximum triangle length to get a good boundry. For some reason i loose a lot of pionts at the edges with this boundry. I have removed points that represents water so i have a part in the midddle that i want a boundry around.

In the good old days I would create 3d polylines by elevation to create curb lines and driveway cuts. The command was in the terrain pull down. Has this feature been completely down away with?

i have just spent 8 hours today trying to find a link that will vary target a poly line that i have set. i cant seem to find the link that will do what i need as per the attachemnt. the section between the edge of the foot path and the start of the fill/cut slope needs to be variable
i know how to set all the targets but this link seems to be a fixed length.

I want to draw a 3D-polyline and wrap it to a surface so that the elevations in the surface aplies to the polyline. With every elevation difference i want a vertrice to be added to the polyline so that it follows the surface perfectly along the polyline length.

I am able to export to SDF but I get nothing when trying to go the two shp formats available. was a "parcel", but i exploded to polyline.
Do i need a patch to make this work? I am a C3D newbie and am struggling wit h user interface, but know that map export command line looks like it is supposed to work.

I am working on laying out data for some survey crews along the centerline of the road. I have a BC and EC elevation, but the vertices along the CL are at different elevations, which were the original elevation of the poly line before being transformed into a 3D polyline. Is there an easy way to make the full line follow the slope from BC to EC other than manually shifting the vertices?

What length is shown in properties for a 3D polyline?
A 3D polyline having two nodes at 0,0,0 and 10,0,0 has length of 10.
If I move the second nodes to 10,0,1000 the length is still 10.
Is that the projection in xy-plan?

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 a problem iterating heights when making a polyline between two different points that have Z-values. I've used Autocad Civil 3D for working with geodetic data with height measurements before and I remember using geodetically measured height values, transforming them into a surface and then when I create a 3Dpolyline within this area the polyline automatically gets z-values that change along the line.
In other words, I could use this 3Dpolyline to obtain a profile that gives me z-values even where there is no exact point with a value has been physically measured. It was a while ago I worked with Autocad and now when I started again I have a similar problem but can't manage to create a surface and get iterated values.
My exact problem this time is:
I have a sewage pipe that runs for several kilometers that is drawn as a 3Dpolyline, with correct x- and y-values. It doesn't have any z-values yet and these are what I want to obtain. I want the polyline to have continuous z-values that changes along the polyline (not only in vertexes) so that a smooth profile can be drawn if wanted. I have data of measured actual z-values for approximately every 500 meters or so along the sewage pipe and these are currently drawn as 3Dpolylines of around 20 meters going perpendicular to the pipe (as in the picture). In other words there are bars with z-values crossing the pipe all along the stretch. Now, what I want to do is to somehow make the polyline that represent the pipe to get the heights from these perpendicular bars with the measured z-values. If I try to draw a new 3Dpolyline between two of the measured bars where the actual pipe is supposed to be, the end vertexes of the 3Dpolyline gets the z-values of the bars. However, the value in between the bars gets the Z-value 0. So, if I start a 3Dpoly on bar 1 then continue the pipe with another vertex, and then finish off at the second bar I will have 2 vertexes with the correct z-value but the middle vertex will be incorrect (0). How do I get the pipe to get the correct z values automatically iterated from the values on the crossing bars? Is this even possible to do? Should I create a surface from the bars first, and in that case how do I do that? If possible I don't only want the vertexes between bars to have iterated z-values, I also want the entire line to have a correct value.
I've attached a crappy image made in paint (since I don't have Autocad on my home PC, only at the office). And just to make things even clearer I'll give an example. Let's say the pipe distance from 1 to 2 is 10 meters, the distance between 1 to 3 is 30 meters and the z-values of bar A and bar B is 10 and 25 respectively. So, when I draw a 3Dpolyline from 1 to 4, I want the vertex 2 to automatically get z-value 15 (since it's 1/3 on the way to B). In the same way, I would like for example the point on the pipe that is right in between 2 and 3 to have the z-value 20. I won't mind redoing the bars to for example singular points instead, if that makes it all easier.

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.

Feature lines are easy to make and great for grading. However, when I try to save the drawing into *.dxf, all the feature lines disappeared. Does this mean DXF files do not take feature lines?
I need the DXF files to up load into GPS. Do I have to redraw everything in 3D polyline?Or is there an easier way to convert feature lines into 3D polylines?

About 6 years ago some people in the Land Desktop group were complaining about not being able to move the text in a linetype so as not to obscure other entities.
how I went about it and a drawing showing an example. Drawing is 2012.
I don't say this is going to replace linetype. I'm also going to see if there's a better way of doing this with Civil Objects. But I've wanted to figure this out for a while and had some down time today. So this is for you to play with if you want. I was looking at my Undocumented Commands file and that reminded me of it since this done with un(or little)documented commands.
If you open the drawing. Select one of the magenta circles (nodes) in the center of the text to activate grips. Select a triangular grip and use it to slide the text along the polyline.

I need to have a table that updates when I change the length of a polyline, These lines are split up into segments for different types of materials. We usually add this up manually but would like to find a solution that is a little more automated.
I have mostly a background in GIS and have excellent knowledge of Autocad Map. I came up with a solution by creating a shapefile and making a multi-part feature for the segments. I added a table and connected to the .dbf file of the shapefile. I then calculate out the lengths of the line and update the attribution of the shapefile. Easy and took a few minutes to do.
I just want to know if there is a better way of doing this. I have did some searching and have found some information about alignment tables.

I want to create a 3d ployline from a 2d polyline with curves. When I use the convert 2d polyline to 3d polyline command it places a bunch of vertices along the curve so when I go to place elevations on the vertices it takes too long. I want to be able to give an elevation at the pc and pt and have it place elevations along the curve from this info like it does on the stright lines.
