Question 1.In C3D 2013 is there a ceiling to the number of points allowable in a C3D surface? Is it 1.5 million?
Question 2. In C3D 2013, when creating a surface from Point Cloud data is there a maximum point count based on the answer to question 1 - or is a different point count limit applied?
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.
Are there any official document describe the limits in a DWG file? For example, the maximum number of blocks that can be added, the maximum number of layers, the maximum length of an object name, etc.?

Only mention i found in this forum was for civil2011 (i have 2013) and it is no longer available.
From the subject is there any way to apply Link slope to surface with maximum width
View 1 Replies View RelatedI have a large surface (over 1.5 million points and 20 000hectares)
I need to get a point file .csv from the TIN to be able to use it in another program.
-so i've extracted the points from my surface, but they are Autocad points.
-next step is to convert them to civil 3d points.
-I can not select them all when converting them or my computer crashes.
-so i select about 25 000 at a time, the converting takes roughly 10 minutes.
and i have over 1.5 million points to do.
how can i speed this up.

I am trying to set several hundred points along polyline verticies with the point number starting at 5000. There are no other points in my drawing, yet everytime I start the process, it begins at 1. I have set 5000 at my Next Point Number under Point Identity in the Create Points toolbar. I have also verified that the 'Save Command Settings" is set to yes under the 'Commands-Create Points'. We cannot get this to behave as desired.
This is a 2D polyline with no elevations.
I have a point cloud with 161 million points in it. This is basically fine and works well but I need to create equally high resolution surfaces from certain regions of the point cloud. No matter what size I choose my export shape, it will only create a surface from a ridiculously small 750,000 odd points, a 'feature' which has been documented on these forums before. I have POINTCLOUDDENSITY set to 100.
My question is, how can I build a surface from this high resolution point cloud data that has more than 750,000 odd points?
I'm thinking about mosaic'ing - ie. making several smaller surfaces over the required area and pasting them together.

How to change the number of decimal places of the elevation of points?
as the points are labeled with their elevations, I couldn’t find how the number of the decimal places of the elevation be chosen. In this case, I wanted to let the number of the decimal places to be zero.
How to set the number of the decimal places to be zero or 1, for example? how to sepcify it height (size)?

I have a point cloud dwg. Is there a way to increase the number of points displayed? The properties of the cloud say there is 14,000,000, but it only displays 34,000. Is there a way to increase the 34,000 number? See Image.
View 2 Replies View RelatedI have a project where I am removing existing asphalt pavement and overlaying new pavement. I am changing the existing profile and cross-slope to tie-in to the existing profile and cross-slope. know of a mill and overlay subassembly that will allow you to tie the edge to a profile or feature line?
View 9 Replies View RelatedI am trying to overlay a large area,I have a design profile grade that I must use. I need the new edge of the overlay pavement to be 2" above the existing as long as the pavement cross slope is between 1% to 1.5% . If the slope goes above or below the min or max I need it to take the min or max. If I use the overlaymillandlevel2 I am unable to get it to use the overlay thickness since i am using a profile.

View 9 Replies View RelatedI 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.
View 9 Replies View RelatedI 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.
View 4 Replies View RelatedI 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.
View 4 Replies View RelatedWhen I import points from a survey database there is a very large new number being assigned to points that have overlap/numbering conflicts.
I had some survey from one source that was in the 1000 pt # range & additional survey that was in same numbering sequence.
When importing the points I chose "Resolve all" it is renumbering the Point number value to the 5xxxxxxxx range?
Is there some setting where I can change this to a lower # or how/why this is happening?

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.
View 4 Replies View RelatedWhat 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.
Any commands that can make this possible?
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.
View 5 Replies View RelatedI 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.
How can you limit the number of open drawings in a session of AutoCAD. Now I can open up 35 drawings in 1 session which will take up a huge amount of memory.
Is there a variable or something like this that I can limit this to 4 for example?
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!

Is there a way to create a surface by manually selecting the points instead of creating a point group? I survey stockpiles for a local construction company and calculate volumes for them.
There may be 50 piles on one site and it would be a lot easier to create a surface by selecting the points manually instead of creating so many point groups.
