Im using Civil 3d 2012 and I couldn't find the function that I could offset the smooth curve alignment as shown on the attached pdf. I've looked through the offset alignments but those linear, curve-cube-reverse curve, curve-line curve doesn't work much.

I'm working on a project to widen a roadway through some mountains. The problem i am having is getting the corridor to apply to a future surface so that i can determine the volume difference. my profiles show there should be some cut and fill, but i cannot get the model to reflect this. when i try to preform a bounded volume i recieve a "the surfaces do not overlap".

View 9 Replies View RelatedI have alignment with 2 curves at the beginning and end that I want to keep. It has a few PIs in between ke that are not supposed to have curves, but Civil 3D added them in (very short 200 ft radius curves), but I need to take all but the first and last curves out.
I tried setting Constraint Editing - toggled OFF lock all parameter constraints. Then I went into the data and tried to change the parameter. Can't get the curve out. Is there a way to convert a PI from one with a curve to one without a curve?
I can't afford to redraw this alignment - it's being referenced via Data Shortcuts to multiple drawings being used by me and my designer / already has my design profiles and existing profiles attached to it.
How to do this? - Delete the curves and make them PIs only? (without curves).

When I create a line label, one of the components available is “Direction Arrow”. This component is not available for “Curve” labels. I would really like to use C3D labels to indicate direction (I realize curves don't have a 'direction', but I don’t mind manually flipping and reversing the arrow). Is there any other label option in C3D that will draw a direction arrow for curves?
I'm working on a runway in Civil 3D 2011. I want to transition cross slopes along the runway. i.e. 1.5% for sta 1+00 to 10+00 and then transition into 1.0%. I thought super elevation would be the best way to do this (I dont want any actual super elevation, just transitions in cross slope). When I select the alignment and "Calculate/Edit Superelevation" i get the following message in the commanding line:
"_AeccCalcEditSuperelevation No superelevation data has been calculated for the selected reference alignment." It does not bring up the wizard.
My runway alignment doesn't have any curves and I'm thinking that's the problem. Is is possible to create super elevation without curves?
I am used to drafting surveys using Eagle Point Coordinate Geometry & Boundary Survey & I am now moving over to C3D, & I am trying to reproduce a boundary survey in C3D 2010, when it comes to Tangent & Non Tangent curves there does not appear to be any routine that allows you to create them in logical sequence or otherwise from the geometrical info provided on paper maps i.e. Radius, Delta Angle & Length, are there any survey techs on here that have been able to resolve this issue?

I have noticed since using c3d 2013 circle "markers" appearing at the curves on my alignments. I can't find the control to change / turn off?
View 1 Replies View RelatedI noticed when you put in vertical parabolic curves onto the profile tangents it will ask you if you want length or k.
however depend on which one you specify. it will hold on to that value when it comes to changing the tangent locations. for what i am doing now i want k by default. but accidentally i put in length because i just went through all the pi's quickly to put in the curves. but i see no control which allows you to control which type to hold. this is a property inside the vertical curve but it's not exposed to user. once you create by length that's it. until you delete the curve and re enter using k then it will hold k.
I haven't used Autodesk directly since Land Development 2i. I remeber being able to draw lines by distances and bearings with the numeric keypad. The bearing quadrant / DMS input was a fast way to draw parcels from an existing map. When I got to a curve, I remember being able to input radius and Delta angle. I've been trying to find those functions for months now. I found the Line by Bearing command and that works well as long as I don't run into a curve.
How do you draw a curve that's tangent to the previous line with the radius and delta angle? I've been going back to AutoCAD version 12 methods. That is, offset the previous line. draw a circle from the end of the offset. draw a line between the center of the curve and the end of the previous line. Rotate that line with the 12d34'56" format. trim the curve and erase the extra lines.
I've gone through all the curve drawing options in the home menu.I found the CoGo editor in the survey menu but it doesn't draw curves. It just draws a line from the beginning of the curve to the center and continues the traverse from the radius point of the curve. That's obviously either a serious misunderstanding of input or a program bug.
I need to reproduce an alignment shown on some plans. I have not had any luck finding a tutorial about how to re-create an existing alignment.
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 created a horizontal alignment from objects and upon importing it c3d seems to have taken liberty to arrange the lines in order it sees fit. Is there a way to rearrange the alignment tangent and curves and change their direction?

I want to create a 3d ployline from a 2d polyline with curves. When I use the convert 2d polyline to 3d polyline command it places a bunch of vertices along the curve so when I go to place elevations on the vertices it takes too long. I want to be able to give an elevation at the pc and pt and have it place elevations along the curve from this info like it does on the stright lines.

View 2 Replies View RelatedOk I am attempting to add a floating curve from the end of a simple straight alignment. No matter what I do the curve is created from the left end of the alignment. I first created an alignment from objects. I tried reversing the alignment and it still comes from the same point. I tried creating an alignment and drawing the objects using a fixed line. Still from the same point. How do you get it to create the floating curve from the opposite end?
View 1 Replies View RelatedI have a copy of an old plan showing curved boundaries which I wish to recreate in C3D. There's lots of connecting arcs, all of which are annotated like:
RAD 15
CHORD 21.213
121°22'15"
ARC 23.56
T.L. 15
I can see that the first line is the radius, the 2nd and 3rd lines are the length and orientation of the arc chord, the 4th line is the arc length. I've been able to get a correct result by firstly drawing the chords, then adding arcs with the appropriate radii between the two ends of each chord. However, I'm sure there's a quicker and easier way. Sometimes the arcs are separated by short sections of straight line which have length and bearing details as well.
Attached is a screen shot of a short length.
I have an alignment file that is xref into multiple dwg files. For the one file, however, the curve plots as "continuous", while the tangents plot as "center". In all the other sheets it plots fine. The alignment styles are good. Looking at it on my screen it looks fine. The xref is on its own layer (not zero or some random layer). All the psltscale, msltscale and celtscales are set to 1. The ltscale is set to .5 (set to 1 doesn't change anything). What am I missing??

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.

Any way to evenly space contours around a curve in a surface.
Many times I have a steep area in a surface that needs to be displayed using 1 foot contour intervals, and in certain areas the contours are crossing each other around curved areas, like a curve in a ditch. In the past i have had to "fudge" the surface a little to get the contours to look correct.
Can we automatically add sample lines at vertical curve points (e.g. BC, EC, Bottom of curve) ?I need to show the sections at these vertical curve key points.
I am using C3D 2011 but could not find that option when creating sample lines in a station range.
