AutoCAD Civil 3D :: Find Insertion Point For A Surface Label
Aug 1, 2012If I use this code it will give me the insertion point for a block
(setq ent (car (entsel "
Select Main Object: ")))
(setq InsPt (assoc 10 (entget Ent)))
Now if I try to use this for a surface label and try to get the insertion point
(setq ent (car (entsel "
Select Main Object: ")))
(setq oEnt (vlax-Ename->Vla-Object ent))
(vlax-dump-object oEnt)
I dont see anything that will get the insertion point.
AutoCAD Civil 3D :: Find Path Of Determined Slope Along A Surface?
Oct 25, 2013I am trying to draw an alignment for a road. I want the alignment to represent the outside of the curve as the road climbs up and around a mound. Is there not way to do this in Civil 3D?
[URL]
and now I am thinking I will have to do this manually, extract contours, and trim/extend my way to victory...I really would like to have this in a dynamic situation so I can make adjustments. Also, it would be adventageous to have the line actually follow the grade so I dont have to add curves in etc later...
AutoCad 3D :: Extruding Modeling Operation Error - Lateral Curve Does Not Intersect To Surface
Jan 26, 2012I keep getting this message. I know others have posted about it- but back int 2006 [URL]. The referenced link showing the solution is no longer available.
I read on an archived blog somewhere that is was a glitch in autocad2005. I am running 2010- so I don't get it. I really need to extrude these plines
AutoDesk Smoke :: Intersect 3D Surface
Nov 26, 2012How can i make something like in the screenshot , i want to create an intersecton of 2 surfaces. In smoke, the z-order rule : the surface have to be completely behind or in front of other object (not partial). is it possible ? I tried couple of sorting combination but never got good result.

Apr 11, 2012I know I should know this, but can't seem to get it to work.
I have two ~parallel feature lines about 250' apart. I grade the Easterly Ft Line going west at a +1.5%, and I grade the Westerly Ft Line going east at a -2.00:1 slope.
I know C3D doesnt have a tool to intersect them, I must use the intermediate surface approach.
What I did was grade one, create 'Paste Surface 1' then grade the other, create 'Paste Surface 2' and then I created Surface 3 and pasted 'Paste Surface 1' and 'Paste Surface 2' into Surface 3.
Throughout I used 'Grade to Distance'
Surface 3 doesn't come out correctly.

AutoCAD Civil 3D :: Intersect Two Gradings
Mar 25, 2012I'm a bit perpplexed about a very simple grading scenario: intersect the daylighting of two gradings as shown in the screen capture. I would like a solution that is dynamic to changes in either of the 2 gradings.
The intended result is in the 3D PDF.

AutoCAD Civil 3D :: Intersect With And Curved Pipe
Nov 18, 2011I'm using the Intersect With method with two pipes. The Intersect With method doesn't appear to work with curved pipes if the pipes do not cross. If they don't cross the method works, but if they don't then it doesn't find the intersect points properly. This appears to be an issue with Civil 3D 2010 to 2012 API.
[URL]........
In the screen cast image the pipe on the right finds the intersection point with the straight pipe on the left, but not the curved pipe that is in the middle. I've had poor results trying to put in support requests for API related issues.
For Civil 3D 2010 here's the code that isn't working:
oPoints = new Point3dCollection();
Pipe oLateral = (Pipe)lateralObjId.GetObject(OpenMode.ForRead);
Pipe oMain = (Pipe)mainObjId.GetObject(OpenMode.ForRead);
oLateral.IntersectWith(oMain, Intersect.ExtendThis, oPoints, 0, 0);
AutoCAD Civil 3D :: Extract Polyline Where Two Surfaces Intersect Each Other?
Jul 8, 2008is there a way to extract a 3D poly line where two surfaces intersect each other.
i have ground surface and i have dam surface. they would like to show the filler material in the cross section graph.. so i copied then raised the surface the required depth.
so now the surface and side slope of the dam intersect. and i would like to trim the filler material surface to be in line with the dam.

Dec 2, 2011I 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, 2012Has 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, 2012I 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, 2012My 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.

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, 2012I 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, 2013I 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, 2013I 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, 2013Im 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.

AutoCAD Civil 3D :: Trim Surface To Another Surface
May 3, 2013I 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?
