I would like to extend a surface to a outer boundary. When I use kriging to do this my surface becomes too inaccurate, the attached picture shows what kriging does to the surface. In the picture notice the elevations of the surface, you can tell where the survey points are because they are lower than the surface around it. All I need to do is extend the outer points to a boundary and leave the rest of the surface alone.
View 6 RepliesI have survey data of the inside floor of a pond ( the pond has a flat floor ). The surface made from the survey data needs to extend to the outline of the pond instead of the outline of the survey points.
I tried the smooth surface method of kriging with a grid base and I sellected the outline of the pond for the output region and that worked somewhat but there are still gaps between the boarder and the surface.
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 a profile with a couple of pipe networks in it. One of the pipes shown extends beyond the edge of the profile at some crazy angle. look at the picture for a better explanation.

We've had a little nagging problem that we've just been living with, but getting a little tired of it: when building a pipe network the plotted line will stop plotting at the outter wall of the structure, thus leaviung a gap between the pipe and the structure. On a 48" manhole it's hardly noticable, but when the manhole gets larger, so does the problem. Check out the attached pdf and you'll see what I'm talking about.
I've been through all the style setting I can think of, but I thought there might be a variable to take care of it...like the FACETDEV variable for crossing pipe.
How to choose “no color” for the line extending between the contours labels?
I labeled the contour lines but sounds that it draws a line between them. Is there a way to hide this line to give it “no color” to have a better presentation for the entire map?

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?
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.
Is there any way to change the referenced surface on a Surface Elevation Label. I can see the surface in the properties but cannot change it.

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?
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.
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.
all of a sudden whenever I run audit on my corridor file the surface definition becomes a snapshot. To add to the drama, the corridor surface will not paste into an empty surface. Why?

I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.

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?
I used a 2d polyline to create a surface boundary for a surface created. The polyline is a closed loop. For the boundary type it is outer, unchecked Non-destructive breakline, and mid-ordinate distance = 1.
My problem is that when I do this I only get a small portion of the surface to show up within my surface boundary. If I don't have a surface boundary the entire drawing surface shows up no problem.
The purple polyline is my boundary and the light blue is the surface created within the boundary.
Is it possible to export created surface from civil to revit architecture? If yes , How? And if its not possible - maybe i can somehow import cogo points to revit?
View 6 Replies View RelatedThere is a coworker of mine that seems to have an issue pop up in random files here. He is drawing his siteplan on a file received from a consultant, the issue he's having is that if a line has any sort of elevation to it, he can't extend another line to it. He can flatten the line and then extend to it, but if the same issue is tried on any other machine, the rest of us can extend the line without issue regardless of it having elevation or not. The frustrating part is that he couldn't tell the line had any elevation to it until he took the precision value out to 8 digits. The line he couldn't extend to had an elevation of 0.00000004. But as I said, his machine is the only one that has this issue. We are all running AutoCAD 2013 on Windows 7 64 Bit. Is there a setting or variable somewhere controlling this behavior?

Here is the problem: I start by directing your attention to the attached file "LEADER PROB1". As you can see, i have two MLEADER notations. one ("TOP LINE") is above the other ("MIDDLE LINE"). The left side of the text in both mleader notations align and the leader jets out from the left side as well. However, each leader has a different angle at the corner of the leader landing. If I wanted to make the "MIDDLE LINE" leader angel to match the "TOP LINE" Leader angle, i used to move nod where the landing bends and continues on to the leader (circled in red in my attached image).
However, when i move this node, I end up with the angles matching, BUT now the text is not aligned, see attached image "LEADER PROB2".
How can i fix this? Quick Leaders ("QLEADER") works just fine (in regards to landing extensions) but not MLEADERS. I would like to extend the mleader landing but keep the text where it is, I don't want the text portion to move.
what is the setting to tell a line to extend to the face of a pline when that line doesn't actually intersect with the pline? see image below...line 1 will extend to pline faces A and B, but how do i get line 2 to extend to those faces? i know this worked when i used autocad 2008 but i'm now using 2012 LT so hopefully it still works, i just don't remember the command name to control it.

I'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line.
2. Created new feature line by offsetting outside that feature line by 3.16 ft.
3. From new feature line, grade down 10 feet at 3:1
4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.
If I change a point or link code in one of my subassemblies, is there a way I can build my top surface using those?
