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 am having some issues with surface profiles on a dreffed alignment no updating dynamically.
Currently it requires me to set them to static, then back to dynamic and they update.
I am well aware of the issue of dreffed surface profiles staying static. I am using the work around of dreffing in the surface and sampling in the drawing using the dreffed alignment.
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 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?
I 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 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?
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?
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. -
I 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.
What approaches are available in civil 3D to takeoff the surface area of daylight slopes?Which do you recommend for given scenarios?
I tried compute materials but the volume report for cut and fill area is zero - so either I missed something or the compute materials for surface area does not work yet. Then, I tried the QTO manager and linked the corridor codes slope_link and daylight_fill to payitems. Slope_link has a QTO of 1,458,099M2 and daylight_fill has 913.39M2; I have more confidence in the daylight_fill takeoff.
I have an existing ground profile, and a design profile. All I want to do is label the slopes of the design. 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 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.
If there was any way to get deflection angles of an alignment into a table? I finally figured out how to get C3D to label them using the add note label. If this is not possible, is there a way to make a table of the notes? I am using C3D 2013 version if it makes any difference.
I have tried a thousand different scenarios with the new pressure pipes. When I create a new parts list and try to draw a water line, the compass only gives me 3 angles. This is using the "out of the box" templates.
I have an alignment for a proposed steel gas pipeline that is several thousand feet long. The alignment is stationed and set to display PI symbols (triangle) at each change of direction. However, steel pipe is relatively flexible so small changes in direction (a few degrees) are irrelevant and I do not want the PI symbols to display in those areas. Is there a setting (a tolerance so-to-speak) in Civil 3D to edit when PI symbols are displayed for an alignment. For example, I want to set it such that PI symbols are not displayed unless the alignment changes direction by more than 10 degrees at a given PI.
I've got a closed traverse that has all the elements, but when I try and analyze it, I get the dreaded error: Insufficient angles, distances or points to calculate this loop. Creating a Traverse for Adjustment: [URL]l and my screen capture looks very similar to his, but I'm not getting any results.
I have 2 alignemnts and 2 profiles, is there a way to to combine both alignment profiles to one profile? What I am doing is moving the centerline of a road over 10 feet, so that is why I have 2 alignments (existing CL and new CL). So what I want to show on one profile is existing centerline, existing centerline of new centerline, and proposed centerline of new centerline.
I have a question about profile table.As I indicated in this picture, I wanna to have 2 different number for each profiles but this table repeats only EG number.
I have found recently that surfaces that are sampled in profile views are not synchronized when the drawing is opened. This is incredibly frustrating when I'm just opening a file to plot a new copy. If I forget to resynchronize the drawing, the sampled profiles will not plot.
