we are missing tool in SAC for stripping a surface exactly the same way how Stripping Pavement or Striping TopSoil works. There is no tool to copy and vertical offset part of the surface. I found out some workaround with Point Delta X on Surface and then vertical Offset, but this is very complicated and I am not able to follow each peak of the surface. Surface link is not suitable for Topsoil stripping.
View 9 RepliesI am trying to create a pressure pipe network (right now I have 2 pipes) and have it follow a surface. When I click to follow surface it lowers the vertices but does not add any additional vertices to make the entire pipe network 5' below surface. My pipe lengths are set to 18' and the surface I want to use is set in my network properties.
View 4 Replies View RelatedSo, I really like the ability to have a pressure network pipe follow a surface but, what if I no longer want the pipe to follow the surface? Is there any way I can get rid of all the extra grips that are added to the pipe in the profile? The only way thing I've come up with is to delete the pipe and recreate it.
View 1 Replies View RelatedI am modeling an existing storm system that is under capacity. After running the model, some of the flows seem to be incorrect. I have one section that has a known flow of 1.31 cfs. The results for this pipe section shows 28.82 cfs (peak flow during analysis) and 6.06 cfs (design flow capacity). The pipe section is a 15" with constructed slope of 0.0088 ft/ft. The max velocity attained is 23.48 ft/sec. I know that the downstream is undersized. Could this flow rate be caused by the downstream backflows? The model is setup as hydrodynamic and rational method. My inertial terms are set at ignore, time step = 0, junction surface area = 0 and variable time step with safety factor 75%. I have gutter bypass flows and my sag structures have ponded area set at 100.
View 8 Replies View RelatedI am wanting to get the peak flow back into Civil3d to add to our long sections, I assume the Peak Flow in SSA is the Flow rate property for the pipe in Civil3d, the HGL stuff seems to come in ok. I am just doing a basic rational analysis in SSA is there a trick to getting the data?

Attached is my 1st project using SSA for detention pond design.
Where is the best place to view the results for the detention pond peak outflow and maximum HGL?
Also, the program seems to separate the results per year storm...anyway to view the results for all year storms in the same report?
how do you attach the .spf file?

I am having difficulties modeling culverts within my model for the 100 year flow. I have seen the sample file within SAS, and all of my culverts have a storage node at the upstream end with a weir representing the road. However, when the weir is utilized, peak flows are artificially high. For example, despite a basin only producing 11.7 cfs, the weir has 8.94 cfs and the pipe has 10.35 cfs. I am using hydrodynamic routing with a 5 second routing time step.

When trying to draw or stretch a line or grip along an object in 2013 it does not follow the osnap like it does in 2012. For instance if I draw a line and then want to draw another line from the beginning of that line along that line using the nearest osnap and inputting a distance, the line follows the cursor rather than the snap.

I am trying to get a street assembly to follow a top of curb profile. The profile is at the face of curb. The centerline of the street is my assembly target profile and alignment. I do not want to create an alignment for the curb. The curb profile is based on the centerline alignment. I can't figure out how to get a link that will track the curb profile at the face of curb.

View 9 Replies View RelatedAm trying to create a corridor datum surface that goes around Protruding lanes but it seems I am Short on knowledge here. the outer lane, LaneOutSideSuper has a greater thickness than the inner lane (same sub assembly) and I would like my datum surface (actually, not only the datum surface but other layer surfaces) to attach its self around the bottom links of both surfaces but it shoots from the Crown_sub to the outer lane Datum.
I have used the bottom links overhang and adding feature lines to the surfaces but it doesn't seem to cut it. Attached is an illustration of the section view. The top figure is what I hope to get and below is what i seem to get.
I did a user defined super for my road. This worked well. However when I deleted the super data. To try something else. The corridor shows 0% camber or crossfall. How do I get the corridor to follow the default crossfall in the assembly again?
View 1 Replies View RelatedI 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.
C3D 2011
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?

View 2 Replies View RelatedI 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.
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 RelatedI'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?
