I'm looking for a way to determine (and preferably edit) the values of P1 and P2, the offsets of the initial tangents into the PC/PT of the shifted curve. It's not in the (admiteddly basic) book I have either.
[Edit: OK, after double-checking,I just found Widening offset clothoid, but I'm still none the wiser.]
I created a profile for an alignment (which has 2 offsets) and also an assembly with two assembly offsets. I wanted to create a corridor where my assembly offsets will have the same profile but will be on different alignments (alignment offsets).
In the corridor properties / parameters, I got an error : duplicate profile found. Should I copy the profile (for each offset) in different profile views (for each offset) ? Or there is a better way to do that ?
How do most people move points imported into a survey database that was shot with GPS and have offsets for trees, poles, signs, etc.
View 1 Replies View RelatedI need to make interchange shoulder widening for my sub assembly.
there is picture where I have the shoulder which I want to add target offset in corridor to make offset of the edge of shoulder. but I don't know how to write expression that when top link will offset slope will move with it and the bottom link will connect in crossing of this two points.
What I have is a highway that is being twinned, however the divided lanes are not consistantly the same distance away (or the same width of roadtop). I would like to keep the number of alignments to a minimum. Both lanes would be based off the same vertical profile. So I would like to have a single assembly that could adjust the median width in the center, and the lane width. Targetting the horizontal layout you can see in the attached screenshot. (this is not all of the job of course)
Is this a feasible task for the targetting assemblys? Would be a fairly standard 4:1 side slopes, adjustable ditch bottom width, 2% crowned road otherwise.
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.
Is there a way to create a table of stations and offsets along a specific alignment at chosen locations?
Dynamic would be preferred.

I draw an alignment for road. I turned off design criteria and i used data from manual for my country Slovenia. I need spiral in, curve and spiral out on alignment. Finally i got that alignment. Then i insert sample lines along the alignment. Then i saved autocad civil 3d file and shut down the program. When i reopen file, i see that sample lines after the spiral in being erased. Sample lines stayed along first tangent, after that they were erased.

I have a page of plans, it shows the center line going from a back tangent, into a spiral, through a curve, and spiral to tangent. How do I create an alignment from this data?

I am a surveyor and I'm having a hard time understanding the alignment creation tools, in my data collector it is much simpler, you enter the back tangent and the end radius and the length of spiral and whale, but I'm trying to build a corridor, so I can stake the dtm.
I know I can use "<[Geometry Point Entity Before Data(CP)]>" (or after...) .
But this text is tooooooooo long.
Is there any way to get only the :
- radius - length of segment. or - Spiral A ???
Maybe using expressions? In this case any hidden elements?
I know I can use segments or multiple segments but I want to do the work in only 1 labeling step ...
why a line drawn perpendicular to a spiral curve in C3D is not radial? If so, what is it perpendicular to? It can result in several feet of difference.
Also, labeling an alignment along a spiral using the automatic routines appears to run perpendicular (whatever that is - not radial).
Perhaps I'm not looking at the math right (its been awhile since spiral curves in college) but it seems to me that a curve of diminishing radius should be labeled radially. Is that not how C3D sees it?
The only other thing I can think is that C3D is running perpendicular to the small tangents or arcs that it puts in to approximate a spiral curve.

I have got a drawing with an alignment containing spiral-curve-spiral entities. I need to find what type of spirals are used in these entities - clothoids, cubic parabolas or other. Is there any way, to find it? In panorama and sub-entity editor there is only spiral description without exact type.
View 2 Replies View RelatedI'd like to view the parameters of my aligments elements near the geometry points. That is, the station and the radius value or spiral parameter (or what I want). I have explored the text & reference text but there is not R or A elements...
How is it possible ? C3D can detect the type of geometry poinr, so it would must to know R, Lenght,. A, etc....
In addition I 'd like to do it using the aligment label set.... sci-fi , isn't it ?
When you have to create plans, the aligments need to show a lot of information. Doing it manually is so boring..... (and in XXI century ...... )

I've attached a screenshot of some "webbing" I have going on between regions in my corridor. As you can see on the left, there's the start of a left turn pocket lane, which is why I have two different assemblies. This is just one instance, but this is happening along my entire corridor. I've given up on trying to resolve and have made gaps in my corridor. But me being an engineer, gaps bother me and would rather figure out a solution. I'm wondering if it has anything to do with point codes?

I have a large fill area directly dropping to to a large cut area. All of the above work is in rock, There is a retaining wall along a section of the "cliff face" but not at the ends where the cut and fill meet.

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?
With Civil 2010 I used superelevataion to transition a street's cross fall from left to right. It was very straight forward with 2010.
Now with 2011 it appears that I cannot add superelevation to an alignment with any curve and change the crossfall of a street from left to right over 20m.
I want to add a single transition curve between two reverse curve in Civil3D.
I am using Civil3d2012.
How to create a transition crossfall over a distance in assembly. For example, I would like to get hard shoulder crossfall along the edge of travel lane from proposed 2.5% to tie in the existing (e.g. 1%) over 10m.
View 2 Replies View RelatedIs it possible in civil 3d to input a cross section of superelevation as parabolic rather than straight section in civil 3d. We are looking at a parabolic bend of 40 degrees.
View 6 Replies View RelatedI have a grading that, going left to right has a a region of relative elevation, a transition followed by another region of relation elevation.
I need to change criterior of the transition region to another relative elevation with the appropriate transition on either side.
I deleted the original transition grading (with the menu commands) and tried adding the 3rd relative elevation but keep getting prompted for a transition length instead of the relative elevation (I am choosing relative elevation criterior). It seems the feature line doesn't want to let go of the original definition. I should be able to replace that original transition with a new criterior, No?

Along my corridor I have different assemblies I used. My sidewalk is curb side in some locations and in different locations there is a boulevard between the curb and sidewalk. I want to transition between these different assemblies and I want that transition to show up in the cross sections I cut. Isn't there a way to tell Civil 3D to transition from one assembly to the next one as you could in Eagle Point?

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.
