AutoCAD Civil 3D :: Creating Points Displaying Cut / Fill Depth Between Two Surfaces?

Oct 18, 2013

I created a volume surface between the as-built and design surfaces, now I would like to show the points that display the cut/fill depths between these two surfaces.  I tried modifying the surface property of that volume surface but doesn't seem to offer what I want.

AutoCAD Civil 3D :: Minimum Fill Depth For Sub Assemblies

Jul 11, 2013

I have a road that I am engineering and have set up my subassemblies using the daylight standard. But i would like to force a cut section until the fill gets to 2'. so that when i have 2" of fill it will still cut my ditches.

AutoCAD Civil 3D :: Subassembly Composer - Ditch Depth In Fill Condition

Feb 2, 2013

I am trying to create a custom subassembly using SAC 2012 that will place a 1' deep ditch at the bottom of the slope in a fill condition.  The trouble I am having is how to hold a consant 1' depth on the backslope and vary the foreslope since the daylight offset and elevation is variable depending on the slope of the existing ground.  I need the attachment point to be the edge of the shoulder so it seems like a loop that varies the foreslope length would be required but loops are not allowed.  I will also have the option to target a profile but I also need the ability to hold a constant ditch depth.

How to model this condition.

AutoCAD Civil 3D :: Control Points Coordinates Of Nurbs Surfaces

Sep 6, 2013

Any way of viewing the coordinates of the Control Vertices (Control Points) of 3d or 2d  NURBS Surfaces. I tried to use the "properties" of the 3d NURBS surface that i designed but i could not find them anywhere..

i would also like to ask if it is even possible to export these coordinates to txt or even more to Excel.

AutoCAD Civil 3D :: Displaying Points In Drawing As Manually Create Them?

Feb 20, 2013

I was wondering if there is a setting somewhere that can be turned on to display the manual points I am creating as I create them instead of having to go back and update the point group before they display in the drawing?

AutoCAD Civil 3D :: COGO Points Not Displaying Elevation Properly

Jul 1, 2013

I have a rather odd situation.  I have input a small table of survey points (we don't have access to a data collector, so it had to be manual).

I have a properly located and back-sited setup, with all of the points located in 3 dimensions.

The Northing/Easting/Elevation data is calculated and displayed for all of the points in the "observations" table accurately.

Every point has the same display/labeling properties/settings, but only 2 points properly display the elevation as calculated.

The problem seems to be that the points aren't accurately retrieving the Elevation from the table.

For some reason, in the “Properties” dialogue for the points that display properly, the “Point Elevation” field actually contains a number; whereas the points that don’t, the same field reads “*PROPERTY NOT SET*”.

This makes no sense, because in the table that defines the points, the elevation is accurate for all of the points, and I can’t find a difference in the table- or in the point properties- between the correctly displayed points, and the ones that are missing the elevation label.

AutoCAD Civil 3D :: Creating Two Surfaces Do Not Interact

Jun 14, 2013

I'm trying to create a surface under my 'existing ground' surface. There is shallow rock where one of our projects is located and using geotechnical data I want to create a 'rock surface' at the known rock elevations. I just want this surface for visual reasons and do not want it to interact with the existing ground or pipe network.

I have 4 places along the roadway where I know the rock elevations. I created new points around each known point with the same elevation so there would be more than just four points on the surface and so I could make it the width of the road allowance. But when I look back to my profile of the road, it shows the existing profile drop to the rock surface at each place that I created points for the rock elevation. Not sure how to make it so the existing ground surface doesn't pick up the new points I added for the rock elevations.

AutoCAD Civil 3D :: Creating Inside Masks On Surfaces

Sep 19, 2013

I'm modeling a couple different alternatives, and I want to make an inside mask on EG where my FG surface will be.

Is my workflow the problem, or are surface masks just buggy? 

I've created three EG surfaces, EG-1, EG-2, and EG-3.  I pasted the dref'd EG into each one, so now I have three copies of EG, one for each design option.  Each surface is on its own layer.

I have three FG surfaces, one for each design, FG-1, FG-2, FG-3.  I want to use the outer border of each FG in turn to make an inside mask for its respective EG surface. I can make one, masking FG-1 out of EG-1.  When I move on and try to make the mask for FG-2 to mask EG-2, no mask is created. Is it not working because I pasted the same original EG into each of the three EG option surfaces? Do I need to promote the original dref'd EG and copy it two more times, so each mask is applied to a completely unique surface?

AutoCAD Civil 3D :: Creating Thickness Contours (difference Between 2 Surfaces)

Mar 1, 2012

I have created 2 surfaces of a matierial that is buried, using drill hole data.  I have a surface for the top, and then a surface for the bottom of this material.  I then created a 3rd suface comparing these 2, creating an isopac contour showning the thickness of the material.  My question is there a way to make the zero (0) contour show up?  I have a .5 contour interval, but 0 doesn't generate.  Could i be missiing something in the settings?

AutoCAD Civil 3D :: Automatically Creating Breakline From Existing Surfaces?

Nov 15, 2012

Our company, was contracted to create a DTM of a residential neighborhood using our Lieca HDS C10 Laser Scanner.  Utilizing the Leica software I was provided LandXML file that contained a 2ft by 2ft Mesh surface along with breaklines for the edge of roadway, driveways and sidewalks, which was imported into Civil 3D 2012.   

Our client now wishes for us to provide them with a breakline for the crown of the roadway.  My first thoughts on calculating such breakline was to set the Contours at an interval of 0.05' to identify the crown of the road, then drawn the break line along the crown based on contours. 

Is there a way to automatically create a Breakline from Exisitng Surfaces?

AutoCAD Civil 3D :: Creating Surfaces From Existing Contour Map For Volume Calculations

Aug 30, 2012

I am working on a project, I was given a file with the contour already mapped out. I am tasked with finding volume of a fill I had to create. I made a 3-D polyline at the elevation I want my fill to start from and going down to my final grade. How can I make surfaces with my map. I do not have any files to make the surface off of. What is the easiest way I can make a layer, TIN has already been done but no surfaces are in the file.

AutoCAD Civil 3D :: Creating Points On A Grid

Apr 18, 2012

I'm having troubles using the create points on grid command. When I run the command, I keep getting asked to type in the point description for each point. I have about 5000 points to create. 

Is there a way to set a description for all the points, so I don't have to do this manually?

AutoCAD Civil 3D :: Creating A Surface From Points?

Jul 30, 2013

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.

AutoCAD Civil 3D :: Creating Points With Certain Descriptions

Nov 29, 2012

I created a Description Key called "EP" and it will land in a "S-PTS-EP" layer automatically.

I then created a Description Key called "NEW EP* " and created it to land in a new layer called "S-PTS-EP-NEW". But, when I manually create a point called "NEW EP" or "NEW EP BC", it does not land in the "S-PTS-EP-NEW" layer.  

Is there some switch I need to turn on or is my description not complying with some naming convention?

AutoCAD Civil 3D :: Creating Points According To Elevation

Jan 3, 2013

I have a number of 3D polylines that where exported from SDF previously created. They have numerous vertices, each one with a given elevation.

How can I create/highlight the higher and/or lower point in each 3D polyline??

A different solution would be automatically breaking these polylines in slope changing points (i.e. high or low points).

I understand that i can create points according to slope or elevation, but it has to be done manually, each poly at a time, and by tipping numeric values that i am sure that a powerfull software (as Civil 3D is) is able to calculate using the drawing information.

AutoCAD Civil 3D :: Creating Surface From Existing Points?

Jun 11, 2013

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.

AutoCAD Civil 3D :: Creating Blocks From Cogo Points?

Feb 11, 2013

We are in the middle of upgrading from LDD2008 to Civil3D2013. This is a 2 part question. Since there are NO point labels similar to Poiint labels in LDD2008. It is making cleaning the elevations up very teadious. With point labels that are just Mtext. I would rotate 1 label and then match properties to rotate the rest and then jiust more the elevations to make them readable.

How do you all deal with cleaning up the elevations?  Is there a way to match proprties as far as the rotatiion of the points? or do you Create blocks from Cogo points?

So, I starting playing with the Creating Blocks from Cogo Points. This creates a block with attributes similar to the way Softdesk treated points back in the day. I ran into a couple of issues. 1 being, it rounds the elevation to 3 decimals places.

When it creates blocks from the Cogo Points some of the blocks are giving me 0.000 elevations for points that had actual elevations.

AutoCAD Civil 3D :: Creating Points At A Specific Number?

Apr 19, 2012

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.

AutoCAD Civil 3D :: Creating Additional Points And Data Shortcuts

Apr 12, 2012

I have a Drawing "A" that is the source drawing containing the existing ground surface, topographic linework and features, and points in the Survey Database which are under the Survey tab.

I have a Drawing "B" that is the source drawing containing the Design alignment and profile with references to the data in Drawing "A" such as the surface.  

If I create additional points for survey stakeout purposes within Drawing "B", will it automatically be included in the survey database in Drawing "A" along with all the other points or is there some procedure in order for me to continue adding additional points into the database from Drawing "B" or any other drawing that references Drawing "A"?

AutoCAD Civil 3D :: Creating A Surface By Manually Selecting Points

May 21, 2012

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.

AutoCAD Civil 3D :: Creating Points Manually From Cross Sections

Apr 12, 2013

Is it possible to create manual points from a cross section.  

For example, I want to create a surface from a sketched (hand drafted) proposed cross section by clicking on the different points on my cross section and having a point created in my plan view.

I am working with an ancient engineer who swears by hand drawing data into the cross sections, and then wants me to produce proposed contours based on this data.  I am trying to get out of writing down the Station, offset, and elevation, and then manually creating points and having to type in the offset and elevation again.

The lines are not parcel lines; they are only line segments.

AutoCAD Civil 3D :: Creating Point Table With Screen Picked Points

Mar 15, 2012

I'm working with both Carlson 2012 and Civil 3d 2012 so this could apply to either one.

I have a set of caissons that were shot on separate days, and they started in the middle when they shot them in. I wanted to create a coordinate table, with the points listed from the northernmost point to the southernmost point. I had thought there might be a way to create a table with dynamic input, where I could pick the points as I go along and have the information entered as I pick.

Is there any way to renumber the points via drawing a polyline connecting them, starting with the one I want as #1 and ending with the last one?
