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.
View 9 RepliesI 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.
View 7 Replies View RelatedI'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 have a fairly simple corridor, however, I had to modify the alignment, rebuild the corridor and resample cross-sections. Now my right daylight slope won't show up. It shows up in the section viewer, but not the cross-section. I had this problem once before and fixed it, but now I can't remember how I did...I have all targets, sections sampled match corridor sampling etc.

This seems like something that should be really easy but for the life of me I can't figure it out. I even started looking at using the Subassembly composer to create a custom SA but that seems like a ton of work so something that would seem to be a common problem.
I need to provide a v-ditch with 2:1 side slopes at the toe of a 2:1 fill slope. The flow line of the ditch should be 2 ft below the daylight point of the roadway pavement section.
My problem is that the conditional subassembly seems to evaluate the height of fill directly beneath the attachment point of the conditional SA (pavement section daylight point in my case – “Daylight_Sub” Point code). Instead I need it to evaluate the difference in elevation between the catch point of a 2:1 daylight fill slope and the conditional SA attachment point (Daylight_sub). If that difference is less than 2 feet, I need to provide the ditch, otherwise I can just use the daylight slope for the ditch foreslope and the existing surface for the backslope.
how to do this? Maybeits as easy as using a predefined daylight subassembly that I'm overlooking?
Here’s my current assembly attempt:
And the resulting behavior. It is solving the 2nd fill condition when I would like it to solve the 1st fill condition:

View 1 Replies View RelatedI am using a feature line to create a grading for a residential house pad. The county grading ordinance calls for a 6' drainage terrace (bench) when slopes exceed 40' in vertical height. I know that for corridor grading you can specify a slope bench with a subassembly but that is not what I am doing here.
I'd like a solution where the grading remains dynamic because I know that benching will cause slopes to cross property lines. I also want to keep the dynamic nature to be able to make adjustments to balance the earthwork.
I am trying to grade up to the base of a retaining wall that is at a variable distance from my known breakline at a certain slope (i.e. 3:1). I know I can set a feature at the base of the wall and "manually" use a reference point and set the slope to 3:1, but I was looking for a more efficient way of doing this?
I am in C3D '09 right now, but we are in the process of upgrading to '14. Maybe (fingers crossed) this is in the updated version.
Can you not perform a slope-slope intercept to place a PVI? Essentially holding the sta and elev of the PVI's directly before and after the PVI of interest and changing the grade in and out so that the sta and elev of the PVI of interest are changed.

i need a shoulder subassembly that varies slope in relation to the lane superelevation slope. i know that i can get a subassembly for the shoulder that will follow the alignment superelevation xml data but in my case i can't use it because we are just adding a shoulder to an existing road. we're not changing the superelevation of the existing road, just milling and overlaying and widening. right now i've created a profile of the outside edge of the shoulder that gives me the correct shoulder slope but whenever i change my centerline profile i have to redo the shoulder profiles which is a real time suck.
View 9 Replies View RelatedI am in the process of transitioning from land desktop to Civil 3D. I design roads in steep terrain and sometimes need to have my catch (daylight) slopes change. So my question is, how do I change a daylight slope at a specified depth? For example, from the shoulder of the road I want a 3:1 fill slope to a depth of 10 feet than change to a 2:1 slope until it catches the existing surface. Can this be built into a subassembly such that if the fill is less than 10 feet it will daylight correctly at a 3:1 and if the depth is greater than 10 feet then it carries the 3:1 for 10 vertical feet and then changes to the 2:1 until it daylights?

View 3 Replies View RelatedI am trying to create a station-offset label style that will drop the trailing zeros in the offset section - e.g. 15' instead of 15.00', but if the offset is not at a whole number, e.g. 15.01, etc. it will display the entire offset.
I created two expressions: IF(OFFSET-TRUNC(OFFSET)=0,.1/12,.00000001/12)
and this one: IF(OFFSET-TRUNC(OFFSET)!=0,.1/12,.00000001/12)
I then created two offset components, one called truncated, and one called full, and assigned the heights to match the expressions.

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 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?

View 3 Replies View RelatedI have been asked to put a feature (a diversion berm) at the daylight line of a roadway where cut conditions exist off the proposed shoulder. Because of the length of the project, it would be useful if this could be done automatically as part of the corridor, rather than creating a feature line from the daylight line and grading it separately.
Is there a way to continue an assembly past the initial daylight line and make it conditional to cut situations?

Original intent was for daylight to have 4:1 slope and keep within the R/W. This causes some areas to hold water as shown circled in the image. I know I should be able to give it parameters or targets to avoid this.
