I am trying to create in my sub assembly a daylight with a variable slope to a graded ditch then it back slopes to natural ground. (image attached). How can I do this in Civil 3d 2012?
View 9 RepliesI just want to start by saying I have been extremely impressed with the speed and effectiveness of finding Civil 3D solutions through this forum. However I do not think there is a way to solve the problem below without making a custom sub assembly.
There is a common problem that I run into when modelling earthworks on airfields. All Taxiways and Runways will have sepirate areas that determine the slope of earthworks in that area. As an example I will explain my problem for a Runway.
Any ruwnay will have a Strip area (150m offset from its centreline) and a Clear and Graded area (105m offset from its centreline). Therefore any earthwork slopes between the runway pavement edge and 105m offset from the centreline will be determined by the requirements within the Clear and Graded Area. Likewise any earthwork slopes between 105m and 150m offsets from the centreline will be determined by the requirements of the Strip area.
My problem is that when overlaying a runway, the new earthworks required may extend beyond the clear and graded area (and into the strip) at some points but not in others.
Therefore I would like a sub assembly that does earthworks at a set slope unless it passes the clear and graded line where it would then continue the earthworks using a different slope. It should be pointed out that the clear and graded line will be present along the entire length of the runway and the earthworks may or may not extend beyond it.
Just for the sake of clarity, when I say earthworks, I mean the subassembly within autocad that will "Cut or Fill" at a set slope until it reaches a chosen surface level. Similarly the "clear and graded line" and "strip line" are 2D and mearly delineate the areas in plan.
save time and make my model more dynamic. As it stands I have been getting around this problem by modelling the earthworks at the initial slope (clear and graded area) and then manually amending the corridor to use a different assembly where the earthworks extend beyond the clear and graded line.
I wonder is it possible to have a daylight (or other function) that can give a different slope for datum and for the top. This would be useful for if you have different rules (e.g. because of geotech) with regard to temporary and permanent batter slopes.

When I click my line label style and turn on the text it labels the existing ground and the design ground. I cannot find the setting in my two profile styles to turn the slopes off in the existing ground.
Oh, how can I get a tick on the V.C. dimension line?
I tried to work with grading but it didn't work,
1 - The square helicopter pad is flat and grading with 2:1 fill, 1:1 cut.
2- The second FL is 2% slope down and grading with 2:1 fill, 1:1 cut.
3- The third FL is slope down to meet the existing road, both sides will same cut and fill.
I am using Civil 3D 2012. I am drawing a water line in a profile with a vertical scale of 1" = 10'. I am trying to draw lines at 45 deg angles to account for standard fittings.
Now, I tried to block a 45 deg angle and exaggerate the y scale, but for some reason this does not work well mathematically. Is there a way to draw lies at a certain slope, or at a certain angle from another line, while taking into consideration the scale exaggeration?
I was wondering if it's possible to add surface slopes on grid (similar to how there is a tool for adding spot elevations on grid). I can do them individually at a grid spacing but that's tedious, and considering you can add spot elevations on a grid, I'm not sure why this wouldn't be possible.
If there isn't a built-in tool for this, would it be possible to make a block of a bunch of one-point spot slopes and you simply choose which surface & the insertion point when you insert the block?
I have a ditch and a road that need to follow separate profiles but be integrated with each other as a single corridor and the ditch's 3:1 slope needs to meet up with the road's 2% slope. Is it possible to have the two subassemblies target each other without having to create a dummy surface or a feature line for targeting to?
View 6 Replies View RelatedI have a surface and i have the outer border of a pond i want to create (see attachments). What makes it difficult for me is that different areas of the pond have different slopes. The area marked as "A" has a slope of 1:5, the are has a slope of 1:2 and the rest of the pond has a slope of 1:1.
My problem: I do not know how to grade the borderline so i end up having a surface with different slopes as my pond.
I have a large ex surface that I have divided into basins and such. I know need to evaluate the slopes in these areas. To do the whole surface at once seems to not be possible. Is there a way in c3d to view analysis information for a section of surface for instance in a polyline or fence?

ROUND(({Pipe Slope}/0.5))*0.5
but it only returns 0.00.
I am looking for either a corridor style or surface style to display slopes while in plan view while working on a corridor. I know you can turn on slope arrows as a surface style, but I am actually looking for the grade to be displayed next to a slope arrow. Hopefully I am explaining it properly.
I just am looking for a better way to spot errors before putting surfaces into machine control without checking station by station in the section editor.
I am new to Civil3D And I am using it for one purpose, Im working at producing planning drawings for solar farms, and the client has asked to me produce topographical surveys highlighting where the gradient or the slope is greater than 15 degrees. Is there someway i can use Civil 3d to do this?
Ideally im looking at producing a 3D Model which has shaded areas for the areas which are above 15 degrees. And Hopefully another shaded for areas between 15 and 10 degrees, 10 and 5 and 5 and 0
The topographical surveys i am downloading at the moment are from a site called promap and are DSM Type?
Our provincial standard requires subgrade and subbase surfaces to have a normal cross slope of -3%. The base and asphalt surfaces have a normal cross slope for the driving lane of -2% and -5% for the shoulder.
I have been trying to figure out how to do this in C3D. I have thought of different ways of handling this for a straight tangent, but have not tested them. What is causing me the most grief at the moment is how to handle this in a curve with super elevation.
The transition will be different for -2%, -3% and -5% Runout distances.
Can C3D handle this? What about using Subassembly Composer?
(I should mention that I have tried with Subassembly Composer, but I am not sure how to deal with superelevation. -

How to make this label where I can show the design slope in plan.
I am trying to create a label for slopes in cross sections for a surface created from breaklines using gade breaks as you can not weed segment labels
I am weeding the labels out based on the change in grade of the section profile and making the label text high very small of the labels I do not want to see. But the first label returns ??? because there is no grade coming in so I get ??? instead of something usefull like null. Any way to convert?? to something you can evaluate and use.

View 9 Replies View RelatedWhy I can't mirror the Daylight Inside ROW Subassembly? For some reason I can only place it on the right side of my assembly and in the subassembly properties there is no option to flip it to the left. In the Modify Subassembly section when it's selected the mirror option is greyed out.
What I am trying to accomplish seems simple enough:
I have a utility easement in a drainage ditch that is 30' wide with a sewer line designed down the center, we need a very simple 10' access road on the uphill side of sewer line with 4:1 Cut/Fill slopes on either side when possible, however when the 4:1 won't catch within the easement I need it to daylight within.
At first glance the Daylight Inside ROW seems to be the appropriate subassembly for this instance but I can't get it on the left side of my road.Is there a way to set up this parameter with a different subassembly because I can get other subassemblies on the either side just fine, for example, the Cut Slope Layout Mode subaasembly works but when I build my corridor with it the slopes tie outside of the easement in several locations.

Is it possible to make a bench right before the daylight line meets the top surface (Original Ground)?
The Road prism is a tylical shape that has a u-shaped ditch on one side. The daylight line from the outside edge of the ditch follows a series of comlicated benches at set elevations and then terminates at OG with no trouble but I'm trying to get an additional bench to be generated before OG (see attached + yellow lines).
how to add this extera bench?
I'm modeling a simple corridor (12' lane 2%, 6' shoulder 6%, 4:1 to match EG). I used the "LinkSlopeToSurface" subassembly for the 4:1 to match the EG. Unfortunately our EG isn't always wide enough for the 4:1 slope to match it somewhere.
Is there an assembly that would use 4:1 as a standard daylight slope, but where necessary adjust the slope, max. 3.5:1, to match EG surface?
I am working on a project where some of the corridors require different daylight slopes. I need to transition between a region with 2:1 slope to a 10:1 slope. My local civ3d support said something about using grading tools to achive that.
What I understood was that my assemblies should not have any daylight sub-assembly and that i should grade the corridor and than add a transition zone between the different gradings. Did I understand correctly?
I have a list of offset distance from centerline on both sildes (left and right). I want to use this to create a polyline that represents the daylight. these offsets are taken from an old hardcopy drawings of cross-sections. is there any way to draw this polyline that follows the alignment?
file can be .txt or .csv
I need to daylight to an offset, to create a clear zone/fall zone, but it must have a maximum slope of 6:1. If no daylight is found at the offset and maximum slope, then grade at the maximum slope to the offset then daylight to the target suface at a steeper slope.
