AutoCAD Civil 3D :: Possible To Modify Only Specific Portions Of A Surface?

Feb 13, 2013

I am curious if it is possible to modify only specific portions of a surface? For example, I have recieved an xml surface representing FG for a project, and want to do an earthwork calculation, could I raise and lower only portions of the project say by using specific boundaries for the asphalt paving, concrete etc. and then implement the raise & lower surface feature for these portions of the FG surface.

At this time I have been creating multiple surfaces for each particular feature of the site, then paste the FG surface, add a boudary and lower appropriately. Finally, I have to go through and paste each particular feature and its small surface into one "subgrade surface" to get an accurate representation. This method results in countless small surfaces and alot of leg work for something that seems like it should be simple.

I know that the surface defentions (FL's or corridors), should they be provided, would make this easy, but there have been several occasions where these are not being made availble by the project sponsor.

AutoCAD Civil 3D :: Hide Portions Of Corridor Surface From Displaying Contours

May 3, 2013

I have tried multiple types of hide boundaries,etc. for this, and cant find a solution.  I'm sure it is very simple, but..

I need a corridor that transitions from 2% sideslope to 0% sideslope.  This transition occurs in a horizontal AND vertical curve.  I understand I could use EOP alignments, profiles, etc to achieve this.  I dont have the time or civil3D knowledge to figure this out on a friday afternoon...

So... my plan is to not apply the transition, and just hide the contours in the transition area and sketch them in by hand.  I want to corridor surface to remain so that when other profiles are created from this surface it is still somewhat accurate (instead of removing this portion of corridor surface, and adding simple contours to the surface).  I just want the surface hidden for +/- 50'. 

Everything I have tried hides the surface everywhere, including new profiles from the surface.

AutoCAD Civil 3D :: Creating Specific Contour On Surface?

Mar 4, 2012

I 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.

AutoCAD Civil 3D :: Surface Volumes In Specific Areas

Apr 16, 2013

I have a 100 acre park that I am doing earthworks.  I have 1 proposed and 1 existing surface.  The park is now broke into 5 different areas and I need to get cut and fill for each area.  Is there a way to do a volume report for a particular area?  I could define the area with a polyline.  Or do I need to copy the proposed surface and start chopping up into 5 areas?

AutoCAD Civil 3D :: Possible To Create A Specific Contour In Volume Surface

Mar 2, 2012

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.

AutoCAD Civil 3D :: Cut / Fill Surface Labels - Color Specific

Apr 29, 2013

I followed the steps I found online to create color-specific surface labels (I assigned red to the cut elev and green for the fill elev.), but when I display them using the spot elevation on grid, I am getting both red and green elevations on same point (they are both fill elev or cut elev.), and why are there two elevations (cut-red and fill green) displaying?

AutoCAD Architecture :: Modify Roofline Causes Surface Hatch To Cover Windows

May 27, 2013

I am having a problem in an elevation view where the surface hatch covers the windows after I apply a Modify Roofline command in the construct.

When I look at the elevation in an isometric view you can see the surface hatch go through the windows. When I refresh the elevations after the construct xref is reloaded after Modify Roofline command the windows are no longer visible.

If I reset the modify roofline command in the construct, reload the xref in the elevation the elevation returns to normal.

I'd like to figure out why after the modify roofline command the windows are covered in the elevation but not in the construct view.

AutoCAD Visual LISP / AutoLISP :: Change A Specific Attribute From Specific Block To Specific Value

Dec 7, 2011

I've had a simple lisp I've been using for years that suddenly disappeared.  It required that you identify a block name, tag name, and the value that you want the tag to be.  All of this is performed via command line, so it is scriptable.  Since I lost it, I've been experimenting with -attedit.  This command comes frustratingly close to what I'm looking for, except it only appends an existing tag, or replaces a specific string within the tag; I can't get it to replace the entire tag, regardless of its value.

1> Any lisp routine that does what I describe?
or
2> How to make -attedit replace a tag value without regard to what the value currently is (like a * wildcard)?

AutoCAD Civil 3D :: How To Correct / Manipulate Surface To Show Proper Flat Surface

Dec 2, 2011

I 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?

AutoCAD Civil 3D :: Reduced Maximum Length For Surface Triangles Causes Surface Holes

Oct 22, 2012

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.

AutoCAD Civil 3D :: Editing Existing Surface Using Edit Surface Command

Nov 14, 2012

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!

AutoCAD Civil 3D :: Volume Bounded By Existing Surface And Design Surface

Dec 10, 2012

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.

AutoCAD Civil 3D :: Add A Surface To Blank Drawing / Then Upload DEM Files To Surface

Oct 2, 2012

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.

AutoCAD Civil 3D :: Import Surface Into Revit To Merge Surface And Buildings Together?

Jul 29, 2013

I have a project involving 3 programs. I am creating a planned development in 3d to be 3d printed when finished. The project is a 5 acre tract containing 8 buildings. I have built the surface in C3D and each building in Revit. The buildings are not in the same Revit file. For my solid work, I will bring the files over into 3ds Max Design to section into smaller quadrants to build in the 3d printer.

The questions:

Would it be better to import the surface into Revit to merge surface and buildings together?

Would it be better to import the buildings into C3D to merge entities?

Would it be better to bring those entities into 3ds Max and then merge them into one? Will 3ds Max Design allow me to insert entities accurately in the environment?

AutoCAD Civil 3D :: Creating Subset Surface From Main Surface

Sep 15, 2013

I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.

i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline.  This seemed to work, but  when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.

AutoCAD Civil 3D :: Create Cut Fill Surface From Existing Surface

Mar 1, 2013

Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.

The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.

I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.

1. Novapoint is quite unstable and crashes alot

2. You cant create profiles out of 3d faces

3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface

4. A large surface made out of 3d-faces demands alot of computer power 

So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.

I 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.

AutoCAD Civil 3D :: Trim Surface To Another Surface

May 3, 2013

I was wondering if there is an easy way to trim one surface to another.  Right now, I have two slopes (3:1) that are perpendicular to each other. They meet at a corner and I have extended them past each other so that I could see the intersecting edge.  Now I would like to trim them to each other like you would a polyline etc... but I am not sure how to do this.

If I select surf trim, it tells me they are the wrong object type, but they are tin surfaces?

AutoCAD Civil 3D :: Possible To Modify Water Drop Trace?

Feb 12, 2013

We work on landfills that need stormwater control terraces and letdowns.  It occurred to me to ask if there is some way to modify the water drop trace function (which examines a surface and determines the 90 degree to contours path) so that you could specify an angle to the contours of your choice.  This would basically automate finding the flow path of a diversion berm. Any method of laying out, for instance a 2% flowline along a 3to1 slope or tougher yet, a face with variable slopes.
