I've been trying to lay a mesh on top of some contour lines. I've also tried the loft command, but with little success.
I've tried several terrain plugins, but they all seem to malfunction because I have overlapping contours. Here is the dwg, what I'm trying to make.
I just upgraded to Civil3D 2014 and Windows 8. When I create a TIN surface using a DEM file no contour lines are displayed. Points are processed and triangles are created and can be displayed but no contour lines. Contour line layers are set to display in the style file.
View 9 Replies View RelatedI'd like to be able to create a surface or mesh from contour lines to give a better 3D representation of terrain than just contour lines. "Drape" seems to be the tool ACA, but I'm wondering if AutoCAD can do something similar. LOFT sorta works, but even then, I have to do it in sections, and I'm not really looking for a solid.

Not sure if what i'm doing is right or wrong, I've never used civil 3d. But i'm getting break-line errors whenever i'm trying to create the surface from the contour lines.

I have this contour lines from dwg file (see attached) and I am trying to make a surface out of it. Initially i thought it is already a surface for C3D but i cant seem to follow tutorials. While browsing for solutions from the Internet, it seems it is not even a contour file that can be added in C3D. what is this file and how i can convert it into a surface in C3D?
View 5 Replies View RelatedI would like to create surface from contours and extract points (with value) from on it. I had contours in my drawing; each major and minor contours are single polyline with elevation (Z value).
If I create surface form CONTOUR, some polylines (major or minor) are not included in to surface. After the creation of surface, I tried to erase the existing contour lines (Polyline) from drawing but the surface will be disappearing.
If I create the surface from ''DRAWING OBJECTS'', I'm not able to select the polylines (attachment 01) .
I created surfaces in Civil 3d 2011 for existing and proposed and I did a surface volume between them. Is it possible to create a specific contour in the volume surface that represents the fill volume elevation (daylight line I think)? My proposed surface is a flood water elevation and I need to define the boundary at that elevation.
View 3 Replies View RelatedSo I have finally been able to create a surface that I like and slice some 3D solids using this surface. But now I would like to draw some contour lines of that surface. I have seen some videos about creating contour lines (such as this one: URL.... ). But in this video they import the surface using the 'connect to data' button in the toolspace area. Is it possible to insert a surface from your drawing into the toolspace area and then draw the contour lines? I managed to insert the layer containing the surface using Data --> Add drawing data --> Drawing layer... but I cannot change style or create contour lines.
View 7 Replies View RelatedI have csv file of co ordinates (x,y,z) I surveyed, I have to produce progress drawings showing stockpiles, boundary etc. , which I can do easily enough by uploading the co ordinates. I would like to include contour lines in the drawing but how to go about it. I have spent a while searching online & I'm even more confused, most discussions refer to TINs and triangulation but not sure how to go about it. I have a survey of the site survey csv file prior to any works carried out & that is what i would like to base my contour lines on. The site is relatively flat, about 4 acres in size, relatively even rectangle shape with fall of 200mm from north to south & fall of 2.5m from east to west.

As you can see, the nature of my model forbids me from making a 3D solid using LOFT.
The top surface is consisted of 3D polyline and arc, which if "joined" will be become a spline.
The bottom surface can easily be joined into polyline.
If I loft the top and bottom, it'll only give me a LOFTED Surface, which is not I want (wanted a 3D solid).
Is there a way to create hatching for the slopes surface style instead of using solid colors?
View 2 Replies View RelatedSo I received a whole bunch of contours from an architect. They are lines and arc. big sweeping arcs. Whats the best and fastest way to create a good surface. I can change them globally to a polyline but I need to add vertices like every 5 or 10 feet to get a good surface. Can I select multiple feature lines (after converted) to add vertices?
View 3 Replies View RelatedI need to create points with surface elevations along sample lines. The points need to represent the verticies one would see in the section editor.

View 1 Replies View RelatedI just received an almost-new Wacom CTL-470 tablet from my father yesterday, so naturally I began fooling around with Photoshop line drawings and simple art.
The initial problem I discovered was that, oddly enough, the basic brush tools, when dragged, would not create a solid line. It would only create a dotted line, the spaces between dots varying with speed of the pen against the tablet.
If I dragged the pen slowly enough (very... very slowly), it would create a kind of shaky line, which was just dots very close together.
Naturally I thought it was the tablet's fault, but upon trying to use the mouse to do the same function, the problem persisted.
I use Photoshop CS and I didn't change any settings at all today.
I would also like to know how I can use my tablet to create a tapering effect with my pen pressure. The "pen pressure" setting in the Brushes menu seemed to have no effect.
Here's an example of the issue, both in large brushes and a smaller one in the background.
I have finally created the shell of the complex surface that you see. This is only a section of the part because I cannot show the whole thing for proprietary reasons. I formed solid surfaces using the network command. The propblem is that it will not convert to a solid because the surface seams are not "water tight." When the network command created the solid surfaces, the surface seams do not exactly match the lines so there are gaps in all the seams. I have tried blending, patching, etc. and nothing works. how to convert this to a solid without losing the outlines and the shape?

View 9 Replies View RelatedI have a drawing set to UTM83 Zone 14 Meters and my drawing units is set to meters also. I created my surface from my point cloud. When i do the contour extract feature (surface object extract), the contours elevation is in the wrong datum or elevation? The surface contour is 620 but the same extracted contour says 188.97? Curious why this happens. It seems to me that it is back calculate elevation or datum to a different coodinate system.

View 1 Replies View RelatedI am using Civil 3D 2011 and wondering how to create just one contour on an existing surface at a specific elevation. I need to show where floodwaters would get to at a specific elevation so that contour would be the easiest way if I can contour the surface with just 1 elevation. I don't want to have to create 0.1' contours all over the site and then remove all the extras.
View 8 Replies View RelatedSo I have an existing grade surface and I am laying out a number of different site designs. I've got all my surfaces from those site designs on different layers each displayed in a different layout. I need to label existing contours on each layout in different places. I've setup additional contour label styles (two for each design, major, and minor) and layers (two for each design, major, and minor). However, when I add labels to my existing surface, they come in on the right layer, but whenever I freeze any of the many layers my contour labels are on, they all turn off. The only workaround I can figure is to make copies of my existing surface for each design option and label each independantly. However, this is inacceptable as far as data management goes, since my one file will be hundreds of megs with all those surfaces.

I have 400 files each represent a tile of contour at 0.5m interval, if I xref all into one dwg it is extremely slow. These files have some 3d blocks which represent xyz and I made a .net program to open each file with "readdwgfile" method. However turned out that the points are not dense enough to generate the same accuracy contours as the 0.5m contours.
I am going home now to use my home computer and see if it can handle all these files xrefed and then bind and explode.
Worst case in make another program to extract only the contours and insert into a blank database. Always difficult when not given raw lidar point files.
Total size for these contour files combined is 327mb.
We have microstation capabilities not sure if it can put in the file in an easier way. I can work with the xrefed bogged down file. But is there a way to only export what's shown ? I have frozen the layers for all other objects from all the references.
I estimated total points from contours will be 20 million. Since each generate about 50000 points. Which is still workable. The computer i use in the office just make this more difficult. Slow cpu. Difficult day. Spent 7 hours programming and got it figured out but didn't solve the problem. I should have known better 20 points are not enough to generate that look in the 0.5m contours.

I'm working on a topo survey and the contours are crossing each others (See attached pic) and what I did was edit the surface by adding points. I know that these points are fake, but how does this affect the terrain surface for design point of view? I did try swapping edge and deleting lines but makes it worse. Also as you can see in the pic, I don't see the added points like it did back C3D 2008.

View 6 Replies View RelatedWhich is better to do: contour smoothing or surface smoothing? I did a little test with a surface with no smoothing, a surface with contour smoothing set to medium, and a surface with surface smoothing. The results puzzled me. The contours in the surface with no smoothing matched the contours of the surface with surface smoothing. The profiile of the surface with no smoothing matched the profile of the surface with contour smoothing. Are these results typical? I was surprised that the contours of the surface with surface smoothing didn't look smoother. I was also surprised that the surface with no smoothing and the surface with contour smoothing generated the same profile.
View 3 Replies View RelatedIs it possible to weed contour lines displayed in a surface based on the slope? I am having an issue plotting construction plans due to steep cut slopes and flat adjacent areas. I have several cuts ranging from 33%-50% adjacent to flat areas around 1%. Due to the drawing scale required by the client and the .2FT and 1FT contours required to detail the flat areas, my steep cuts appear as dark hatches due to the tight contour lines.
View 1 Replies View RelatedHow to use the Surface Contour Label Group class in the .NET API.
My first guess was that I had to create an instance object of the class and name it, and then use a "Create" method (e.g., CreateMultipleAtInterval) from there, like this:
Dim labelgroup As SurfaceContourLabelGroup
labelgroup.CreateMultipleAtInterval(arguments)
However, this doesn't work, as Visual Studio told me "Warning: Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."
I tried just saying:
SurfaceContourLabelGroup.CreateMultipleAtInterval(arguments)
But that didn't seem to work either. How this class works and get it to add some contour labels to a drawing?
