I am working on a project that requires me to calculate how much gravel I have to take out of a steep hillside when I am designing a route for a pipeline and a road. I is it possible to do this in Civil 3d and how can I do it?
View 5 RepliesMy problem now is that i have piles of gravel & sand, i got the volume on each pile for and now want to make a cross section drawing showing the elevations on them. I went to section views and create mutiple views but it asks me for a aligment, but i just want to base the drawing off the contours of the piles (elevations)
View 5 Replies View RelatedA lot of my work is on steep slopes, and I need to incorporate sloping driveways, parking areas, site retaining walls (boulder walls as well as inter-locking block walls), benches between the top of one wall and the bottom of the next, re-grading, and landscape plans into the design model.
It seems Revit lacks any real site tools to accomplish these tasks, and there are some work-arounds. I've been playing w/ floors for a sloping driveway, but it's tedious and the results are mediocre at best. Haven't yet played with ramps for driveways. I haven't yet figured out a good way to deal with site retaining walls, where the bottom is sloped to match the driveway, and the top is at a different slope to match the existing/re-graded terrain above.
Any work-arounds to address issues with modeling driveways & retaining walls on a steep site?

The formula I am using is S = I*L/A
S = Average Slope
I = Contour Invertval
L = Length of Contours (ft)
A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
Trying to calculate a catchment area to allow me to size some culverts using Civil 3D 2012 Sp#1.
" The specified location results in a Catchment with no area."
After sitting for 15 miutes I keep getting the above message. The surface is huge and there is an obvious catchment area (or I think it is obvious). The surface was generated from contours and cover an area of approx. 8Km x6.5Km but the catchment ares should be around 15-20% of that area.
I tried another one upstream about a Km and it worked fine. So the one I am doing now should encompass the upstream area as well as from that point downstream to the Discharge Point.

With reference to the picture attached, I am trying to find the overlapping area between two different cross-sections. I.e.the area of green minus the area of white.
The hard way to do it would be to sketch a closed polyline over the area I want but I have about 100 of these to do and more to come.

All we have is an alignment and a surface. In one region we need to calculate the stripping that is 6m wide x 1m deep.
I used LinkOffsetOnSurface to get the surface elevation on the left and right side.
I then tried using the stripping subassemblies but no luck.
because we have a number of regions and assemblies we would rather use corridors than creating a stripping surface.

View 6 Replies View RelatedI’m using 2011, due to printing issues in 2013. My question relates to determining how runoff gets diverted, or spreads out, after leaving a well defined channel.
I have a street intersection scenario. It’s a “Y” situation in which the main trunk of the “Y” is curbed and contains all the water for the three storms I’m studying. Runoff flows towards the two streets that branch off. I need to know what percentage of runoff water splits during the 2-, 10-, and 100-year storms from the main (curbed) roadway to the other two streets - one curbed, one uncurbed.
I assume that velocity, runoff volume, storm intensity, street cross sections, slopes, and other variables play a big role in how the water diverts, but I’m not sure how to set up this scenario in SSA. Do I somehow use a weir? Do I use an open channel, or user-defined channel? I have a subbasin area defined with my concentration point at the end of my main curbed street before the water splits off. I’m not sure where to go from here when it comes to inserting links, weirs, channels, etc.
how I can set this up? I’m not even sure it’s possible to have the software provide this type of calculation.
I have a few questions regarding spread/street capacity:
When calculating the spread at the catch basin locations, how does it determine the curb height?? Does it always assume 6"?? what if it is a roll curb??? is it olnly determined by the "throat height" of the inlet?? How can I calculate my spread on random spots throughout the street??

I have an acad document connected to some .shp files, which contain polygonal shapes with some meta-tags.
I want to achieve the following: draw a polygonal shape and select all the tangent areas (I already know how to do so)take a property of those areas and calculate an area-proportional [or: area weighted] average value (proportional to the partial area defined by the drawn polygonal shape). I tried to achieve this by splitting the objects and merging them again with defined splitting (area proportional) and merging (average) options. The problem is: splitting & merging doesn't work until I disconnect the data files (checking the objects out doesn't work) and even then I can't split the areas. And, more important: This doesn't create a weighted average and I don't even want to manipulate the objects! I just want to get one value out of all these steps.
I appended a screenshot of my file. E.g. I want to take the value 923.2 and multiply it with the corresponding area percentage it represents in the drawn shape. So the calculation would look something like 0.02*923.2 + 0.2*926 + 0.12*945,9 [...] until all the 100% are covered and I get one single representative value.

From what I've read of similar posts a few people have had the same question but have been instructed how to do it with volumes as opposed to area. Also how to insert a table of cut and fill area analogous to the one you can inset from the volumes dashboard.

To calculate the volume ,I need to include this uneven rock surface wall.
For doing so,The sharp edge will displays in the cross section.
Because the uneven surface, I cannot create the surface with normal step.The TIn line will joins horizontally,not in vertical direction as is intended.

I have a hatch (ANSI31) enclosed by a closed polyline. Whenever I change the hatch from ANSI31 to GRAVEL some of the hatch shows up outside the boundary. The Polyline consists of both arcs and line segments, and the hatching errors are occurring within the radius of the arc segments. Changing it from Associative to Non Associative makes no change.

i created new polygon´s SDF (ACAD Civil,Map2011). And created new feature from geometry (from 2 closed plines - island). See on attached picture. If polygons are more complex =erroneous result from calculation ("Round ( Area2D ( Geometrie ), 0 ) "). It means ACAD calculate sum 2 areas together, but It should dedust island from main polygon.
