I have got a csv file and want to add to the surface but it says error in adding point file.....don't know what to do. Size of the csv is 13MB and contains about 0.2million points.
View 2 RepliesI am trying to visualize a road project. The problems is, whenever the corridor surface goes below the EG surface (when the road is in cut) the EG surface is the only visible surface.
I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.
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.

My surface is not recognizing the grade change when I make the polyline into a wall breakline.
I am using AC3D 2014. I have created a surface from downloaded DEM points, but, as expected, the contours are not as accurate as I would like. They vary from known elevations anywhere from a few inches to several feet.
I also have survey data from approximately 500 points which include Northings, Eastings and Elevations. Is there a way to add these points to my existing contour surface and incorporate these know NEZ points such that he contour surface is more accurate?
I have already converted my "known point" file to a .txt format with comma delimited information.
I'm looking to add a column to my point table that will subtract a fixed number from all my surface elevations. I'm working in 2011 Civil 3D. I've been researching this for the past couple of days and haven't been able to come up with anything solid yet...
View 5 Replies View RelatedI am having a lot of trouble adding retaining walls to my surface. I also have to add the curbs of parking lot.
I already have the surface. However I need to tell Civil3D to stop the contours at the retaing walls and not to try to tie them in to anything else. The closest I got was using wall breaklines and I got the top of the retaining wall to have the desired elevation. However, all the contours going to the retainig wall try to go around it and tie in to something else. This ends up creating weird contours and crazy slopes.
Now for curbs, how do I tell Civil3D to jump 6" when it reaches the curb line?
When working with multiple building pads and configurations change rapidly. Is there a method to add a Block or Xref into a Civil3D Surface under Drawing Objects? If so, how could you do it.
I want to have a building block type 1 that I can update the block or xref then updates the surface rather than doing each one individually. The Block would have a FFE of 0.00 and then the stoops, etc would either be a 0.1 drop or so.
I am placing a lot of suface slope labels in my drawing (as in hundreds). The default settings force you to choose a surface, and then to place it by selecting 1-point /or/ 2 points. The CAD default is the 1-point. Is there a way to change this default to the 2-point so I dont have to change it everytime?
View 9 Replies View RelatedWhen adding data to a surface, there is the option to add it as a "Non-destructive" breakline. [URL] .....
What is this good for? I created a surface, copied it, and created a volume surface between the two of them. As expected, the resultant volume was 0.
I then draw a 3d polyline and snapped to elevations on the surface. I then took that 3d polyline and moved it up 5'. I then added that breakline to the surface as a "Non-destructive" breakline and the resultant volume between the original surface and the one modified with the new breakline was still 0. Absolutely no change was made to the actual surface, it just added additional triangles.
I'm trying to find a reason it's even option and I'm coming up blank. There has to be SOME reason it's there.
Am I correct in assuming that if Surface Labels by One Point is chosen, the slope as shown is the maximum slope of the surface triangle where the point was chosen??

View 9 Replies View RelatedI'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 5 Replies View RelatedIs 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.

If I use this code it will give me the insertion point for a block

(setq oEnt (vlax-Ename->Vla-Object ent))

I dont see anything that will get the insertion point.
I have created a new assembly that uses a HMA dike rather than your typical curb but my surface always begins at the top of the HMA pavement rather than the top of the curb subassembly. See Picture. Where's the setting to fix this (is it a daylight setting) or it is a bigger problem in that I didn't create the subassembly or assembly correct to begin with?

I think this should be an easy thing to do, but I am having problems figuring it out. I need to repath the location of a point file being used in a surface. My surface will not rebuild because it can't find the point file originally used. Drawing was used on a different computer system, so the point file directory is now pointed to the wrong path.
View 7 Replies View RelatedI'm currently working on a site layout and came across a problem. The drawing that I have has the site layout with all the points and contour lines included. However, the drawing is exploded. Now, I want to get the point properties and surface properties from this file, but it seems like it isn't the original file and it has been edited. This file also does not come with a point file or surface file. Is there a method to get the point, surface or elevation properties from this drawing?
Also, I have heard that you can create a new drawing and create a surface to read the surface properties of the drawing. Is that possible?
I am having a problem using 2014 civil 3D. When I import las files and create a point cloud, and go on to make a surface from those points, it is limiting the "number of points added" to 340134. I am using the lidar las files which each tile or file has an average of 12 million points, and I have tried to create a surface using one file, and up to 28 tiles (where there should be 340 million points). Regardless, one of the files contains 12 million points and I do have the "point density" set to 100, and the "real time density" set to 100. Why will it only use 340,134 points? I have tried all options from "point cloud extents" to "window" and same result. All the points from the cloud are there and displaying fine, it just seems civil 3d is limiting the number of points used for surface.

Surface does exist as we can see the triangles/contours or whatever we choose to display. When we run the Water drop command, we are getting a message saying that the point is outside of the surface. We have selected a valid surface by both picking it visually and selecting it from the dialogue. All layers are on and thawed and we are picking well inside of the surface.
Why it would be telling us that the point is outside the surface?
I have a surface based on a point cloud. I decided to add a few more tiles of data to the point cloud and was expecting that the surface would update (after rebuilding) to include the new extents - but there was no change. The surface doesn't have any boundaries or breaklines but does have edits.
Do I need to add points to surface again? Will this duplicate the orignal point data or would it just add the new data. I didn't want to lose my edits if possible.

I know that there is a limitation on the numbers of points added to a surface from a point cloud. But I'm curious how Civil 3D determines which points to exclude from the surface. Is there a special alorithm/criteria the software uses?
View 1 Replies View RelatedI 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??

I have a bunch (hundreds, so manual input not an option) of X,Y points without elevation data that I would like to import into a DWG and assign an elevation that is based on an existing surface object. Is there a way to do this for a point file? The command for inserting individual points would be the "Create points - Surface > Random" but I don't see a way to do this in a batch type method where i have my PNE formatted input file to just move the points to sit on the existing surface.
View 2 Replies View RelatedI often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.
The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.
How to correct/manipulate the surface to show a proper flat surface?
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 am trying to add points into a surface. I have done this before without any problems, but now I am having issues.
When I ID points which makes up the surface it gives me the correct Z level e.g. 24.5m, however when I hover over the surface it shows me the surface name and a different z level e.g. 0.65m. What is the reason for this difference in z levels? I think this may be causing the issue I am having when I add new points.
I select the surface and use the 'edit surface command' in the ribbon, choosing add point.
When I add a point at the level I require(23.89m), it puts it in a lot higher than the surrounding area, so I tried to put the point in to the lower z levels (0.4m) it puts it in a lot lower!
My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.
Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.
What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?
how do I shrink labels? Where is it in the settings ; the Align folder had been check.
I am issues with DEM files that I am downloading from the USGS website.I download 24k, elevation for the area I need. I then choose staged 1 second, add a surface to a blank drawing, then upload the DEM files to the surface.
The surface imports correcty, but when I try to import points taken by a surveyor on the same drawing, they plot incorrectly.The DEM surface and the points from the surveyor do not correspond. Also, the DEM surface is in meters, not feet. I have tried changing drawing settings, datum types, coordinate types, etc.
