AutoCAD Civil 3D :: Entering Bearings - Distances And Curves
Jul 19, 2013
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 am trying to draw a parcel map using AutoCAD MAP 3D, using distances and bearings that were added by to the original hand-made drawing by the surveyor. The parcels don't quite close perfectly... what the acceptable tolerances are for parcels of say 1 acre and under, 1-5 acres, and 5-20 acre sites?
I'm working with site plans and have a lot of distances and bearings in my drawing.
Sometimes i need to reverse them. Is there a command in AutoCAD 2012 where you can reverse a hole heap of distances and bearings all at once? Mirror make them up side down. I want them to swop sides of the line they refer to.
Any way to add a (R) to the Bearing dislpay, to indicate a radial bearing, in a Line Table?? This would only apply to certain lines, not all of them. I can specify which line. That function does not need to be automatic.
I draw property plats for a surveyor and looking for a way to add the bearings (for example: N 56 15' 32" E) along the property lines. Right now, I use the Distance command to find out the bearing, write it down, and then add it to the aligned linear dimension text. I'm guessing there's a faster way to get a bearing along with the distance without typing it in.
Is there anyway to prevent a corridor from jumping across large distances as in the attached screen shot? There are no targets in any of these regions.
I am using AutoCad C3D. I have drawn a building and now I am trying to position the building on a plot with uneven property lines using only “tie distances” from the spots on the property to specific spots of the building.
I do not know which C3D program functions (with just distances known) to get the building placed properly on the plot.
I've got a closed traverse that has all the elements, but when I try and analyze it, I get the dreaded error: Insufficient angles, distances or points to calculate this loop. Creating a Traverse for Adjustment: [URL]l and my screen capture looks very similar to his, but I'm not getting any results.
When you use the Spacing command to set the work canvas grid spaciing, it requires that you pick a point in the drawing and then enter the value? Shouldn't it just prompt you for a value? Seems like a bug maybe. Am I missing a settings or something?
I have tried unsuccessfully to draw lines using bearings as a surveyor draws them. I have seen a number of posts here and on the web, but they relate to northern and easting’s, but as you can see on the attached PDF from a surveyor they have used only bearings. I’m not a surveyor, my background is mechanical so this is all new to me. what units and settings I may need to change in order to draw using these bearings. I’m using Autocad 2012, and the attached PDF relates to some blocks of land in Australia (just in case that makes a difference in the settings)
First off I'm using AutoCAD 2008 and I'm trying to input survey points to establish a subdivision.
My units are set as follow: length type: decimal with precision set at: 0.00. Angle type: Surveyor's Units with precision set at: N 0d00'00" E. Units to scale inserted content: feet.
I have a specific point at which i want to start from and that is 1421334.93,78320.62 which is my benchmark. I want to start my next point at 113.66 feet away from this benchmark at a bearing of N 5d27'23" W. So far I have tried using the command @113.66<N5d27'23"W but nothing happens.
I am doing a few simple plot plans and I would like to find simpler way to place the bearings of the property lines just by clicking on them or the ends of each line like I do for their length. I just use a Aligned dimension with everything turned off except the text so that is parallel with the lot line.
There is probably a simple solution I'm just not finding one, I cut and past the text out of the quick calculation now and rotate it, and I know there's a better way.
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 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 an alingment and profile, but I cannot use the layout tool to create a curve (vertical)...what I am doing wrong. I select the profile in profile view and right click to select "edit profile geometry" and get the layout tool bar but cannot select to draw a curve...
I have a file saved in autocad 2013 (dwg file extension) that contains level curves and points similar that an autocad civil 3d file and also have the layers. I want to convert this file to a civil 3d file for doing section of the curves whit the program. I don't know if it exist a method or not directly or indirectly.
When i try to Add a Alignment Table for curves , and everry time i select the aligment or it's lable , it tells me that no Item Found,now what exactly i'm supposed to select ?

I 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 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.
Althout I have created the widening on my aliment and used a designer critery on my corridor, I can't achieve that the corridor use the widenig on the curves.
I need that the corridor generate the widening on the curves, I can't stake the corridor without widening.
I have a profile that has a 25' VC (please see attached jpeg) and want to put my PVI Station and Elevation but it doesnt fit in 40 scale (I need it to be in 40 scale). Is there a way I can only change the style for small vertical curves without changing my other styles?
