Has instances where you set your tolerance for the maximum triangle lenth to say 50m to reduce the amount of triangles along the edge that run at long distances. When I do this I end up with multiple surface holes and I'm not sure why as there are points in the area.
I thought well maybe it's because i should've reduced my max triangles first then added breaklines. Would this matter? I also thought I could add a line to the surface to fix the holes vs. deleting surface lines along the entire edge of a surface for many many miles.
I have an alignment with horizontal PVI points that are coincidental with COGO points. I want to display in a profile view, a surface elevation at the alignment PVI points in a band style. Is it possible to do this? If so, how?
i am trying to add as a breakline. i have not been able to get this particular line to work as a breakline and the surface keeps drawing triangles through the line like its not even there. The figure properties show that it is a breakline. The figure prefix database brings the line style in as a breakline from the start.
Today I opened a file that has previously worked perfectly well, only to find that when I open my surface in Object Viewer and begin to rotate it manually, the triangles making up the surface do not appear. I have the contour lines and border (what is enabled in the Edit Surface Style/Display/Model tab) although the triangles (which should be displayed as well) do not appear. Other surfaces show like they should.
Is there another option other than the Edit Surface Style/Display/Model tab and the VISUALSTYLES command?
I have a drawing where points that I create will not display.
I have created points in this drawing before.Previously created points display fine.Points created in another drawing and imported into this drawing display fine.All layers have been turned on and thawed, to make sure it's not a layer issue."All points" point group is the top point group.When I create a point manually everything seems to work fine, info is echoed to the command line, etc., but then nothing happens. Obviously it's a setting somewhere, but it is driving me up the wall trying to figure out what setting. I'm sure I will slap my forehead when told what it is.
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 have an "existing" surface built. But there has been some construction since my company surveyed the site. So, my surveyor went out and got the new points in the area of the new construction. I am trying to remodel the "existing" surface without rebuilding the entire surface. I have removed the old (demoed) points from the point group used to define the surface. But, the points are not being removed from the surface.
I built my surface by importing points directly, ie, not through the ribbon, so i have no points listed in prospector. i have been editing the points (mostly deleting errant survey points) and would like to export the final data set. The only step i found, was to show points in surface style, and then Extract Objects (of which i selected Points).
This seems to have no placed all the points into my DWG, but HOW do I export this files into a single text file??
I have alignement of wall or embankment. I have existing ground including this corridor river. I have also CSV file with points (x,y,z). On my sketch there is drawn. Points present FDL (flow defence level) maximum level of river in case of huge rain or other things. These are almost aligned. I need to transform it (project) into alignment. I have to create profile of EG, FDL (based on this point) and then create new profile of height of wall or bank. What is the best solution for projecting this points. I tried with grading (distance and grade0%) I tried then with offsetting this feature line based on points and used it as breaklines. Created surface had holes.Even real is worst because alignment is perpendicular in same places to river.
I have created a surface with a point group. I have a few points on the edge of my surface that need to be added to the surface. I can add them to the point group, but when I updated my surface nothing happens. The triangles don't extend to my newly added points and my profile of the area doesn't show a surface where these new points should be. the new points I want to add have the same properties as the other points in the point group, they are cogo points.
I have a layout in my drawing (Civil 3d 2011) with multiple viewports and my point symbols (trees, manholes, etc.) won't display. I have other layouts in the same drawing that display them fine, but I need to use this specific layout for what I'm doing. This must be a setting of some sort but I can't seem to figure it out.
Is there a way for me to display different points in each viewport? I have figured out how to freeze layers and realize I can put the points and labels on different layers but am curious if this is the only alternative?
I am building a surface and started looking at the triangles and found that some are going to non-existant points. I have unfrozen, checked, etc. all of my points to make sure they are not in the drawing.
What I have is a tin volume surface. I am asked to label the points with the thickness of the volume surface.So where there was survey data on the top layer I need to have the width of the surface at those same points.
2013 version. Long story short, I am having problems with pressure networks in my drawing so to simplify things I want to just show the top of the current watermain in my profiles because we are not doing anything with the water main, though it needs to be shown in the profile. To do this I created some points where the watermain is and made their elevation 1.8m lover than the existing surface at those points (due to the 1.8m of cover the watermain has).
I then created a surface using those points and an outer boundary surrounding the points. For some reason the surface stops at one point and doesn't continue to the rest (about 5 more points). So when I create my profile the surface stops short. The points are included in the point group the surface uses, and the outer boundary doesn't cut them out either. Not sure why the surface isn't referencing those points.
I have been given a survey on AutoCAD which was orginally 2D with the levels written in text next to it. I changed each point (690) to include the level in the Z-direction. I am trying to calculate volumes of topsoil removal and then cut anf fill volumes.
So I opened up Civil3D in metric template and imported my drawing as I have not been given a ddata file with the co-ordinates. Unfortunately I am having trouble creating a surface between the existing points.
I am working on drawings where we create dtm's from surfaces, use the dtm for layout, shoot the asbuilt of the final surface, and then compare hundreds of shots to the surface to develop an as-build report.
I want to be able to select a mass of points, compare the perpindicular difference in elevation to the surface, and have an excel spread sheet generated from the results.
My coworkers are able to do this in Terramodel but I am on a mission to eliminate Terramodel from my day to day work.

Is it possible to add points to a surface without adding them to a point group? I've got a bunch of ponds I'm doing and it will save me some time if I could just select the points, and not have to put them in a point group then add the point group.
I am having some trouble creating a TIN from a point layer in Civil 3D 2011. Would the best course of action be to extract the points from the drawing and creating a surface from there, or is there a way to create the TIN around the existing points in Model space?
I'm much better versed in AutoCAD, but excited about furthering my understanding with Civil3D.
I have a couple of questions regarding surface volumes/analysis in Civil 3D 2014. First, there used to be a way to determine the volume between two surfaces without creating a volume surface. The command is _AeccReportSurfaceVolume, but I can't find it on the ribbons in 2014 to save my life. Do I need to create a new button myself?
Second, and more important, dealing with the elevation analysis in 2014, and noticed that the colors reset anytime that the volume surface is rebuilt? It has always been annoying not to save a color scheme, but at least once you had set it up, the colors stayed as the surface changed. Is there a new setting that I am missing, or is this just a glitch with 2014?
I have been trying to follow "Autodesk 3d Civil Help>Surfaces>Adding and Editing Surface Data" in order to construct a surface from a point cloud I have, in x,y,z format. I have been trying to creat a grid surface since my data is regular DTM data.
My first issue is that a lot of the options are greyed out when creating the surface (for example I cannot change "Render Material Style". I can still create a surface though. The second, more important issue, is that I am then told to expand the surface definiton section on the Prospector tab and click on the points icon there. This icon is simply not there for me - I have a choice of Boundaries, DEM Files or Edits.
I should point out that I am working in Autodesk Civil 3d 2006.
Is it some issue with the liscence/installation? Or am I missing something erally obvious that greys out some options and makes others dissapear completely!
I have a surface profile which has 2 surfaces in it. The surfaces overlap, and where there is overlap I just want to show one surface. Right now it looks like I'm going to have to smack a new boundary on the one surface to clip it, but I thought there might be a way to limit the display range of one surface in the profile.
Right now, I've only figured out how to do this so both surfaces are limited to the same range, but I can't figure out how to do it if you want to just control the range displayed of one surface and show all of the other surface.
I have a project I designed and grading plan is almost done. My proposed surface lables read as 1256.50. How can I get them to read just 56.50? I have a FG surface I created and am labeling using surface elevations. I am running out of room and need to free up some space. I don't want do drop my surface 1200'.
