what is the trick for holding triangulation within a surface boundary? I recall a setting somewhere but can't seem to find it... attached graphic, would like to hold the surface triangulation within the arcs which are in the surface definition as boundary

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.
I have one cross section, which gets narrow over the particular length.
(C/S : Elliptical roof surface)
In the region where cross section changes, triangulation becoming weired. If we edit surface with swape edge command then it will be ok.
I have attached both the images before and after swapping for ref.
Can we do this by dynamically ? as I have number of areas like this.

I can delete the label once and modify the surface triangulation
View 3 Replies View RelatedI 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.
I have alignments that go in and out of a surface boundary (this is because I have a surface that represents the bottom of pavement.) I want to show the surface profile with the gaps in the profile view (where there is no surface. However in the profile view the gaps are sometimes connected with a straight line instead of being blank.
How can I have a surface profile represent the bottom of pavement properly? (An alignment that is not fully withing the surface boundary.) I know I could add the profile multiple time with different start/end stations But, I don't want that, I want it to be dynamic, as the alignment will change.
The odd shapes are outside the daylight line. They follow a straight-line around the daylight limits (see third attached file), apparently triangulating unwanted areas. I've used a corridor shrink wrap for the surface boundary.
What is the best bet? I'd rather not draw a polygon along the daylight line and use it as a surface boundary, since it could change. Setting a max triangle length in the surface does not seem to provide a desired result.
I have problems applying an Outer boundary to eliminate a small area within a big surface (and a few Hide boundaries within that Outer boundary): Civil 3D somehow creates extra triangles within my surface (that don't really make sense to me). I am applying the boundaries as non-destructive boundaries as I need the surface to extend all the way to my applied boundaries. The surface needs to be untouched (except applying a few Outer and Hide boundaries) as it is design data.

I tried to create a shrinkwrap polyline to use as a boundary but when I picked the corridor in the shrinkwrap command
it locked up my computer. These are just simple corridors with no intersections. Why the automatic boundary only works intermitently? Is there a better/easier way to create the surface boundary?
I need to adjust a surface boundary. I need to remove a corrupted area in my surface. I do not need it. Is there any way to drag a boundary so I can exclude some of my contour area? Is there a command under settings on tool space that I may have overlooked? This surface was furnished by a client so I do not want to rebuild or alter except to exclude some contours.

I use Civil 3D 2011. I have created a surface from a point group. Now i want to extend the surface to an outer boundary. To do so, i do the following steps:
- Select the surface and Extract the border object.
- Create feature line from the extracted border polyline
- offset this feature line (featureoffset) to outside specifying a offset distance and specifying the elevation difference as 0.
- Add this offseted new featureline as the boundary in the definition of the surface
- Rebuild the surface
Now when i am selecting the surface, I see that the featureline is not a part of the surface and I do not find the contours and the TIN extending to this new boundary. Also I still find the old border in the surface.

View 3 Replies View RelatedI'm creating a corridor to widen a road on the left and right sides. I am using OverlayWidenMatchSlope, with various other subassemblies. In places it daylights, in places there's a cut wall modeled from generic links. I am trying to create a good boundary for the corridor surfaces but I'm puzzled by one thing. The OWMS subassembly has a P2 code, but the corridor will not generate a featureline connecting the P2 codes..
I will try adding another baseline, and a new subassembly that will just use a generic link to target the sawcut line (the insert point for OWMS). That should give me a featureline I can use for a surface boundary. Is there a way to generate that featureline from the inside edge (the insert point) of the OWMS subassembly?

I have created a surface from a corridor. I set the boundary of the surface to the daylight of the corridor. In some areas of the corridor the surface does not triangulate see attached.

1. either only import the point cloud in a polyline area i specify
2. add all the points within a boundary not limited to the pointclouddensity = 100, freaking default is 15 almost cost my job today. extremely stressed out right now.
i am talking about extreme lidar surveys. 1km 1km LAS/0.5m contours/xyz files times 355 of them. covers a 2km wide corridor. but i only need 100m wide after i define the road alignment. no need to have all the extra points.
right now i densify the heck out of it and end up like 5-12m points. decent but not good enough because the geotech is bitching about that accuracy is not good for some feasibility study. or is there any software i can do this besides civil 3d.
what i want can also do is automate the 'add points to surface" under point cloud and have the software do multiple boundaries without having me baby it over the night. right now every click is 5 minutes and adds like 400k to 1 million points. Civil 3D 2012

View 9 Replies View RelatedSo I've been creating a building and I can't seem to get rid of (or hide) the lines that make up the edges of my surfaces (or solid) in the animation view. Is this typical?
For instance, I have one side of the building that is using 4 different textures all on the same plane and they butt up to one another (example: brick meets siding). Where these two surfaces meet the lines that makes up the edges of the surface won't go away. Thus always showing white line showing the boundaries o the individual surfaces.
Can I turn these off, hide them, or am I being a total 3D Modeling noob and missing something basic?
in 2012 I saved a layerstate and it shows in the dialog but if I change the stet to another and go back none of the settings are held.

I noticed when you put in vertical parabolic curves onto the profile tangents it will ask you if you want length or k.
however depend on which one you specify. it will hold on to that value when it comes to changing the tangent locations. for what i am doing now i want k by default. but accidentally i put in length because i just went through all the pi's quickly to put in the curves. but i see no control which allows you to control which type to hold. this is a property inside the vertical curve but it's not exposed to user. once you create by length that's it. until you delete the curve and re enter using k then it will hold k.
What setting controls the rotation of leader tails? Specifically in point labels. My dragged point labels maintain their orientation, as I want, with Plan Readability set to False and Dragged State Components - Display set to As composed. But the leader tails are horizontal to the view rotation.

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.
