AutoCAD Civil 3D :: Subassembly Composer - Variable Ditch Bottom With Slope And Delta Y

Oct 22, 2012

I'm trying to build the ditch portion of my Subassembly backwards from an offset target "DitchOffset". The elevation of this point should be derived from a point that is using Slope and Delta Y from point "P12" (see attached). Must be at least 1m from the bottom of SubBase with a 5:1 slope. 

The Ditch Bottom will be variable width. I'd like to be able to select my offset alignment for my ditch bottom. Have a link from this point extend at a slope to the Target Surface to complete the foreslope.

I can't quite picture how to complete the links from the DitchOffset point. This may be complicated but the diagram identify what I'm trying to do.

AutoCAD 2010 :: Draw Slope Lines For A V-Ditch?

Nov 10, 2012

I want to show slope direction in my drawing for a small V-Ditch.

I tried one way by utilizing Measure Command however didnt work out for both face of Concrete V-Ditch because Measure Command aligns the Block on one side of the Line you want to meaure with block.

AutoCAD Civil 3D :: Surface Slope Label One Point

Apr 3, 2012

Am I correct in assuming that if Surface Labels by One Point is chosen, the slope as shown is the maximum slope of the surface triangle where the point was chosen??

AutoCAD Civil 3D :: Slope Percent (%) Label Text Is Not Changing Height

Jul 19, 2013

I have slope % angles labeled on a plan, but they are too large.  They are 1/8" tall, and I need them to be 3/32" tall. I have checked the style (ROMANS) to be sure the text height is set to 0", and it is.  I've also ensured that these labels are on this label style.

Check the screenshot.  I added 2 screenshots with a huge difference in font size just to be sure my point gets across. And, I have hit APPLY and closed the window just to be sure.  You will see up top, I have it set to 3/32".  Actually the text isn't showing right, it is still stuck on 1/8".  But, regardless, you can see in the lower screenshot where I have changed it to 3", but the text has not changed.

As a side note, the text on the slope labels should match the height of the contour labels you can see in the screenshots.

AutoCAD Civil 3D :: Suppress Trailing Zeros In Surface Slope Label

Sep 24, 2013

I'm trying to suppress trailing zeros in a surface slope label in run:rise format. Basically, if it's a 2 to 1 slope, I want it to read 2:1 or if it's a 2.5 to 1 to read as 2.5:1.

I found this blog showing how to do it for line slopes, but I think it's not able to work using the run:rise format.

AutoCAD Civil 3D :: Profile Geometry Editor - Slope-Slope Intercept To Place PVI

Aug 20, 2012

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.

AutoCAD Civil 3D :: Shoulder Subassembly That Varies Slope In Relation To Lane Superelevation Slope

Jan 22, 2013

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.

AutoCAD Civil 3D :: Slope To Depth Of 10 Feet Than Change To 2:1 Slope

Aug 13, 2012

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?

AutoCAD Civil 3D :: Correcting Ditch Location

Jul 24, 2013

I had created a corridor using the attached assembly with conditional cut/fill and SlopeToSurface SA, the cut condition provides a ditch SA at cut only.  Then had the Ditch Bottom Profile to follow a ditch profile that I created, and flows toward the increasing chainage.  The horizontal offset and elevation of the ditch runs perfectly fine as desired, except between Sta. 0+465 (cut section) and Sta. 0+470 (fill section), where the ditch ties back to the edge of shoulder instead of going toward the outside (as shown in the blue lines).

My question is, do I need to make a transition between the cut and fill sections?  If so how much effect and details is needed as I have a few other locations with the same issue.

AutoCAD Civil 3D :: Sump / Baffle Box In Drainage Ditch

Sep 6, 2013

I'm trying to add a sump/baffle box to a drainage ditch. I'm taking this project over from someone else.  They had created a surface. However, I'm confused about how the surface they made was created, but I have used it to give me a reference to were the sump is located on the profile view. (circled in blue).  Currently that surface has wall that are 1.5' high with a bottom at -1.5'.  I have drawn in the sump on the profile view (highlighted in yellow).

I have tried to start over by using breaklines.  I have already created a standard breakline on the N and W side at 0.  However, on the east side, how to create a breakline and keep the drainage basin grading to the exisitng drainage basin grade.

I have attached screen shots of the plan and profile view.

AutoCAD Civil 3D :: Creating Profile Along Lowest Point In Existing Ditch

Aug 21, 2012

In highway construction, I usually check for lowest ditch elevation and see how the existing drainage flows. Typically one would create or specify in CL profile creation with a 15m offset right and left which would then generate existing CL and 15m offset profiles in profile view. However, the 15m offset profile might not represent the lowest point in the ditch as the lowest elevation offset distance varies along the highway.

My question: Is there a way in civil 3D profile creation where it can automatically trace the lowest elevation in the ditch and plot it in profile view?

AutoCAD Civil 3D :: Subassembly Composer - Ditch Depth In Fill Condition

Feb 2, 2013

I am trying to create a custom subassembly using SAC 2012 that will place a 1' deep ditch at the bottom of the slope in a fill condition.  The trouble I am having is how to hold a consant 1' depth on the backslope and vary the foreslope since the daylight offset and elevation is variable depending on the slope of the existing ground.  I need the attachment point to be the edge of the shoulder so it seems like a loop that varies the foreslope length would be required but loops are not allowed.  I will also have the option to target a profile but I also need the ability to hold a constant ditch depth.

How to model this condition.

AutoCAD Civil 3D :: Create Side Ditch As Part Of Assembly But With Different Profile

Apr 10, 2012

I am trying to create an assembly with a U channel (side ditch) that's top will follow the sidewalk it is next to but I need the profile of the U channel to be different than that of the roadway. Is there a way to create a custom subassembly part that will do this? Can I create a different allignment/profile for the bottom of the U channel that can then link to the other assembly?

The only other think I can think of is to use a dynamic block to add the U channel to my cross sections, but that will take a lot of time to do.

AutoCAD Civil 3D :: Ditch Subassembly In Corridor - Using Realistic Mode To View

Oct 18, 2013

I'm using the Ditch subassembly in my corridor and am running into a problem when using realistic mode to view.

I've applied a render material to L3, L2 and L4 which is fine but when I assign a material to L1-L5 (i.e Top) it overdraws (or otherwise fails to display) the previously assigned materials for L2, L3 and L4.

If I set the Links L1-L5 (i.e. Top) to no display then L2, L3 and L4 display as expected but when IMX'd to Infraworks the existing terrain shows through at Links L1 and L5.

Is it possible to stop this from happening and have a seperate material for L1 and L5 whilst retaining L2,L3 & L5 materials?

AutoCAD Civil 3D :: Changing Profile Line Label Style Causes Label String To Revert To Default

Sep 6, 2012

C3D 2013. We have profile line labels, some of which get manually edited (for example, change the "<[Tangent grade(FP|P2|RN|AP|GC|UN|SD|OF)]>" to a static number such as 0.29%).

However, if you CTRL+Click and select one of these labels and change the style of that one label, then the manual edits are lost and the label reverts back to the default string.

Is there any way to turn this behavior off?

AutoCAD Civil 3D :: Using Negative Cut Slope

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.

AutoCAD Civil 3D :: Can't Display More Than Two Slope Ranges

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%. (!)
