AutoCAD Civil 3D :: Recreate Long Series Of Curves From Arc Specs
May 8, 2013
I 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:
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.
I am currently working on a project that involves some basic collision simulation of an LNG ship in Solidworks. However, before I can do that I need to turn the ship (which at the moment exists as a series of curves, see attachment!) into a solid object, which I can then export as an IGES file.
So far I have tried the PRESSPULL command and it hasn't worked at all, only produced a "not responding message".
I recently had to re-format my hard drive and lost the print driver that communicates with the Kip Plotter that I have and Autocad civil 3d 2011. I am needing the Kip10.hif print driver but cannot find it anywhere on the web that I have looked, where I can download this driver, I have the disk for the Plotter but if only includes the drivers for civil 3d 2009.
I'm trying to extrude a series of 3D faces, a very large series, over 200,000 3D faces. I´ve done this before only it was not on so many faces as I can select only like 3,000 faces aprox at any one time or the computer crashes.
I think this problem could be solved, or at least I could save some time, if the extruding preview could be turned off. By extruding preview I mean that when I enter the extrude command and select the objects to extrude, then immediatly there's a preview of what the objects would look like once they're extruded and that's what's causing the delay and the crashes.
I was tried to convert a point from UTM-39N to Lat/Long using geodetic calculator; but when I checked the converted coordinates by another applications (like GeoLab); they were a little different (about two seconds) & I'm sure GeoLab is right.
I am working on a drawing for the COE. They require that the horizontal scale is 1"=20 feet for cross sections. Unfortunately the sections that I need to cut are so long that they don't fit on the page. Currently I am creating multiple viewports in paper space and creating split section views in that way but it is starting to get out of hand.
Any better way to handle sections that won't fit on a page? I can't change the scale.
I am trying to produce some longsections from a DWG Format Drawing i downloaded from a mapping website (promap) at the moment im going through the process of using a 3d polyline, snapping it to every contour i need, then viewing it from the side and drawing a longsection table around it (Pretty amatuer im sure) How is it possible to produce a longsection automatically using Civil 3D/AutoCAD (The contour map is made up of 3D Poly lines).
I have created an alignment and long section and over layed my assembly to produce the corridor through my alignment. However it is standard practice in the UK to show the channel levels on a long section.
In Civil 3D 2013 > Settings tab > General > Label Sytles > Note . . .create a new label style that will label the latitude and longitute of a location in your drawing. Assign your drawing a coordinate system. Now label a point in your drawing with the newly created Lat-Long label. Tell me if it works. I've not had any luck with it. I can do it fine in Civil 3D 2012, but no matter what I do (old drawing, new drawing, any template) it just doesn't seem to work in Civil 3D 2013.
I am wanting to get the peak flow back into Civil3d to add to our long sections, I assume the Peak Flow in SSA is the Flow rate property for the pipe in Civil3d, the HGL stuff seems to come in ok. I am just doing a basic rational analysis in SSA is there a trick to getting the data?

I used it back in college a few years ago so I have some little experience. Not a lot since all we did there was just very basic 2D stuff in R14.
I was wondering if it's possible to have the complete design of a machine in Autocad? What I mean is: design every part to the correct scale, and then generate "views" for each part as needed (with measurements, projections, sections), in different sheets. Maybe even mount the machine fully and explode it.
I've seen the Sheet Sets, Flatshot and Sectionplane commands but I'm not sure how to use them.
For some reason I am unable to get my lat and long's to display using note labeling in C3D 2013.
I can setup a labeling style to add and display NE coordinates where ever I place them on my surface but my Lat and Long label style remains blank.
I've checked layer being on, text size, drawing unit/zone settings, even tried replacing my NE label style call outs in the NE label style text component editor properties to Lat and long and still remains blank in my composer preview....
We are trying to label the intersection points on an alignment with the following info:
Sta: Delta Angle LAT LONG
We can make it work with a Northing and Easting, but there is no option for a LAT LONG under the tangent intersection labels. I tried to make an expression that would format a Northing as a LAT but it just gave me jibberish.
I was able to do it but adding a point at each PI and making a point reference text, but you then have to select a different point for each label.... which works but it is still a multi step process.
Is there any way to change the format of Lat/Long in a C3D point list display from degrees, minutes, seconds to decimal degrees? I have looked pretty hard, but can't find anything. The geodetic calculator only does one item at a time, I think. Any plug-ins out there? I suppose this could be on a wish list as well.
I am using R2012.and have ended up manipulating point values in Excel-not a quick way of going about it.
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'm having some problems using some existing MX highway design data I've brought into Civil3D using the genio import extension. Basically I can bring in all the alignments that I want to be able to use but am unsure where to go next in terms of creating a proposed profile line. My goal is to be able to pull out long sections and cross sections based on this data. Ideally I'd like to avoid doubling up on work in MX and Civil3D as much as possible.
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.
