AutoCAD Civil 3D :: Transitioning Between Assemblies Of Varying Cross Slope
Apr 5, 2011
how to create the transition portion of a corridor design where my road cross slope has to uniformly go from 3% to the right to 3% to the left. I have the two regions set up, but I cannot get that "middle" or "connecting" region where the cross slope is "rotating" around my road profile center line to create this "+3% to -3%" transition.
I have been searching the internet and this forum, but cannot find a good explanation. There is info out there about setting vertical offsets, but not sure how to do this so the cross slope is uniform all the way through this region (i.e., making sure that if the slope is 1.234% on the right side, I will get 1.234% on the left side, etc.)

I need a sub assembly for a lane that you can specify varying cross fall. i.e it starts at -2.5% and ends at +2.5%.

I am adding on to an existing roadway. I want to match my exist.cross slope of the road way which will vary.
When I select to use the parameter reference LinkoffsetandSlope I get a slope, but it is in the wrong direction.The linkoffsetandslope is getting the grade from the existing CL of roadway and the existing edge of pavement.

In attached file the normal cross slope of secondary road(AB) is 2% Right to left (Right higher). and for primary road cross slope is 2% Left to Right (Left higher). I produced this junction using intersection wizard and cross slope of secondary road only starts changing from start of curb return to match the long slope of primary road. Is this possible to increase this transition lentgh on secondary road to create smooth contours.

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.

how to have exisitng cross slopes display on a bank of corridor cross sections...I see lots of posts on this but I am having trouble finding the answer. The link below from Add a section view grade label only adds "A" slope label.....I want all of them in all of my sections.

I have created a road for a pit mine (which is unlike roads I have designed in the past). The road switched back towards itself and I need to daylight the cut slopes to show the limits of the mine/road cut. However, my cut/fill lines are not showing up in my cross-sections, but the plan view is showing the limits of excavation.
I assume this is because my limits are intersecting, from each of the roads, the upper and the lower. How can I get around this, or why are my cross-section lines not showing?

With the default cross slope 2% in place and no profile targets, section views with subject sub assembly come up at 0%
there's some polyline width targets but no verticals...

The intersection wizard makes dynamic EOP profiles based off of the cross slope from the centerline. Well the intersection tool doesn't always work with funky intersection layouts. Is it possible to manually create a dynamic EOP profile based on the cross slope from the centerline profile?

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.

Can't figure out how to match gutter slope to outside lane super subassembly slope. Have super eop targeting a feature line with elevations, but when i check section editor gutter slope doesn't match pavement slope.

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.

I 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?

I'm trying to use assemblies when creating a corridor. The Tool Pallette is emply but I can drag the assembiles in from the Catalog. I've also created an assembly using the ASC. Neither work when I try to use them. The error message is attached.
I'm using a network installation and I do not have the option of changing it to a DVD installation.

Would be interested in a strategy for a varying depth overlay, i.e. where the overlay assembly follows a centerline design profile rather than a pavement depth up from existing grade. Then the trick would be for the software to calculate the asphalt volume between the new top surface and the existing roadway surface.

I have a case with the Subassembly Composer where I have 3 varying depths. InsideLane, OutsideLane, and Shoulder. My Base shape below these 3 shapes will not setup properly. I understand why, it's because the varying depths will create a potential step up or down situation depending on the depth of the top 3 shapes. This prevents the definition of the Base Shape.
For the sake of quantities I'd like to create a Base Shape. I could create Base1 Base2 Base3 (one below Inside Lane, Outside Lane, and Shoulder). I would prefer not to for clarity purposes.
How could one approach this? I'm thinking that I need some conditional components to clean this up. I'm not a pro writing expressions. I basically need to define the links that define the varying depths between the top 3 depths. I need to create another point and link if the depths vary, and that link needs to be included within the shape definition for Base.

So I need an sub assembly similar to the SuperLayerVaryingWidth, but combined with BasicLane Transition sub. If the SuperLayerVaryingWidth sub would follow an ETW profile to set slope, then I would be set. Any tips on how to create this? I'm pretty rusty at building custom subs.

We have just started using Civil 3D. I need to be able to create an assembly that will place a sidewalk at varying offsets (it is too random to make seperate assemblies). I have tried making an alignment of the back of the walk and attempted to use targets in the corridor to achieve this .
I will attempt to attach the DWG that I am working on. The Main alignment is PR-1 as is the corridor and the alignment that i need the back of the walk to follow is PR-1 BWR.

I'm trying to transition away from iPhoto to Lightroom. Honestly I've always liked iPhoto. I've found it very easy to use, and the way it organizes photos into "events" is very useful. However, I'll be doing most of my photo work on a PC, so I'm moving over to Lightroom instead.
I have already exported all of my iPhoto library. Each event has its own folder (named after the event), and all the photos have their meta data. Everything is copacetic.
My question is a matter of organization of the photos within Lightroom. In iPhoto, all the events were listed chronologically, and this made it easy to locate what I was looking for. In Lightroom, however, it seems that the way you navigate photos is through the folder list under "Library," which is listed alphabetically instead of chronologically.
I currently have 136 separate folders. So I turn to you for a bit of advice since I am brand new to this program. Any way to organize and browse photos in Lightroom that I don't know about?

The undefined areas of a slope map now have a hatch to them and are plotting black. This map was created a month ago in 2012 without issues, upgraded to 2014 and now the undefined range has hatch!

I have a simple driveway corridor along a steep hillside. For cut, I would like to have a negative slope away from the shoulder edge. I have tried numerous approaches and all 'cut' reverts to positive. I searched and found no clear answer. It's such a short driveway, I can 'fake' it in, but I would like to calculate quantities.

I am working in an Inventor Assembly .iam, I have about 250 fasteners (screws) that are constrained to a flat washer and lock washer. I would like to put them in as a single unit (sub assembly if you will) and then promote or explode them in the top level so that my bom has 250 screws, 250 washers, and 250 lock washers all at the same level, not associated to one another except thru the constraints that were entered in the original assembly. I have tried Promote but that doesn't work because it removes the washers from the original file and I end up with only 1 instance of the assembly. Am I approaching this incorrectly? Is there a better way? I run across this scenario with different components quite often.

If you have created a sub assembly and inserted it into an upper level assemby, is there a way to bust up the sub assembly at that level?
The issue arising is the individual components need to be called out on the upper level, but in the drawing are all showing up as the same balloon.

I've got a surface that displays contours correctly. When I go to Surface Properties-Analysis tab, I can set an arbitrary number of ranges for contours, directions, elevations, slope arrows, etc, and they display correctly.
I can set an arbitrary number of ranges in the slope range box too, but when I click the Analyze button, Civil 3D 2014 hotfix 1 only displays two slope ranges: 0% to 2979736.0077% and 2979736.0077% to 99999900.0001%. (!)

I'm trying to match an existing slope design that has a soft rounded off top of slope. The toe (green) is a feature line and I'm using a 1-1/2:1 slope to natural surface grading rule. You can see the rounded contours in blue that I am trying to match.

I need to project a surface/grading (or something of that nature) across my berm and have it intersect with the inside bank. This is better explained if you see the attached image. In the plan view you see 4 featurelines. Outside TOE, outside TOB, inside TOB then inside TOE. I need to project the outside TOE across the berm (shown in the section view) then create a new featureline where the line and inside slope of the berm intersect. Note that all the elevation shots vary as does the widths across the berm. What's the best way to do this?
