AutoCAD Civil 3D :: Create Vertical Offset Layout Profiles Dynamically
Sep 14, 2012
I am creating construction plans sets that require 3 road profiles for the left edge, center and right edge. I would like to dynamically link the center line profile with the edge profiles.
I have created alignment offsets to obtain the existing surface at the offset location. I would like the edge profiles to have a vertical offset from the center profile. Also if I modify the center profile I want it to dynamically adjust the edge profiles.
I've heard it said that it's possible to make two separate layout profiles dynamically dependent. For example, making a driveway centerline profile dependent on the roadway centerline profile it's connected to. The idea is that if you revise the roadway centerline profile, up or down, that the driveway profile will automatically go up or down with it.
Is this true? I didn't readily see anything in the profiles area of the docs or the tutorials.
I have a design profile and now I want to create one that's linked to it but have it 0.5m lower than the profile I just laid out. Is there a way to do this? I'd like to keep them dynamically linked so when i manipulate the 1st profile it will drop the 0.5m lower profile. In theory this would be a great feature to have in CIvil 3D.
At this point I will likely need to copy the profile and drop it 0.5m in elevation with edit geometry. Not ideal considering when I adjust the main profile I'll need to redo that process to show the profile 0.5m lower than my main design profile. (used as a side slope target).
I am trying to create a station-offset label style that will drop the trailing zeros in the offset section - e.g. 15' instead of 15.00', but if the offset is not at a whole number, e.g. 15.01, etc. it will display the entire offset.
I created two expressions: IF(OFFSET-TRUNC(OFFSET)=0,.1/12,.00000001/12)
and this one: IF(OFFSET-TRUNC(OFFSET)!=0,.1/12,.00000001/12)
I then created two offset components, one called truncated, and one called full, and assigned the heights to match the expressions.
I have attached the file, the style is ACHD-Sta Off-Rt [copy]
I have centreline alginement and have used the offset alginemnt command to get other alignments for other surfaces (need these as they have all different crossfalls). Now as o go along I reference the veritical profile of the new alignement (created via offset) to my previous surface. Each time i do this the vertical profile does not seem to match my original profile of the centreline alignment. Now as i have about 6 offsets and as i move along these error seems to grow even bigger. how this is avoidable or if this is output is unavoidable
Our firm has finally decided to leave LDC 2009 behind and moving to C3D 2012.I would like to ask a few questions about the way plan and profiles are created with C3D.
In LDC, we would create a full profile that included everything in it, that is proposed and existing centerline elevations and left and right top of curb elevations. Then on the sheet layouts, we would make many viewports that showed the proposed and existing sets, that is centers, lefts and rights. (medians in the example attached)
I've been watching many online videos on how to sample center, left and right and how to create a proposed center line but I can't figure out how to make a proposed left and right profile so that I can control drainage into existing inlets.
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...
For some reason I cant seem to target an offset alignment layout profile with my corridor lane assembly. I can target the existing the existing groundprofile with the same offset alignment, but the layout profile when targetted does not change the lane in my cross sections. I can do this with civil 3d 2010, but not 2012. I have tried other lane sub-assemblies and it doesn't make a difference.
I'm trying to create two offset alignments (one on each side of my centerline alignment). For some reason I can only create an offset alignment on the left side of my CL alignment, but not the right side.
I'm creating a containment dike around and island. I want the berm to tie down to the existing surface, then offset from that tie point 21' to the surface again. I can do an offset from Baseline, or a tie to an elevation in a profile. What I can't do is make the offset 21' from the tie location over an additional 21' to another tie point on a surface.
This is with Civil 3D 2013. I am able to create a pline by offsetting an alignment using any drawing on any other workstation in our office, but on my machine I get an error: "1 object(s) were filtered out." when I try to select the alignment.
This leads me to searching for some system variable or something that is different on my machine.
I'm totally new in Civil 3D. I'm using 3D laser scanner to measure and lately draw 3D "as build" models of tunnels, bridges etc. So now I have 3D model of bridge, which is simply created with layers, 3d faces, boxes etc. - primitive ACAD 3D modelling.
Now I want to create sections on multiple stacions. How to start? Is there any step by step tut with this feature?
Is there a particular reason that the intersection wizard will not create the profiles if you select the horizontal alignments rather than let it create them by offset?? My EOP is not always parallel to the centerline. Why bother giving the option to pick out a name if it isn't going to work.
I need an offset lisp routine to offset a selected line a set distance on each side of the selected line and change the layer of the offset lines to the current layer, and then keep prompting me to select the next line for offsetting until I'm finished.
I'm setting up some plan and profiles (I DON'T HAVE CIVIL3D) with MAP3D. I have a couple of autolisp routines to work with the profile grid, but one thing that confuses me, the grid should be in paper space and the vertical scale set based on paper space, right? I'm assuming that the actual contours/polylines (once I have them georeferenced) will go in model space.
My question is "Can I create surfaces, profiles, & alignments using AutoCad2012?"
I know if I had Civil3D2012 I could do it, but can it be done with the Regular version I should say.
At my previous job I was using Civil3D2010 (darn economy Government job did lay offs) and now I'm using CAD2012 with new employer and I'm realizing that there are a lot of functions/commands that I don't have.
I've been using autocad for quiet a few years, I can do most of what i want but I might be missing some basic knowledge. I've been creating some template for drawing which include different layout A4, A3, landscape and portrait.
If I use plot/print using cutepdf or adobepdf as a printer the results are good (print the same than the preview).But when I use publish using dwg to pdf then my layout are shifted to the right outside of the printing boundary.
I want to create a profile layout by feature line. Is it possible?I have a pipe about 3 miles long, an alignment along the pipe, and a provie view showing the exisitng surface and pipe network. The pipe network was created from a feature line. I projected the feature line to the profile.
This is why I want to do this: I need to label the horizontal and vertical angle points of the pipe in plan view. I crated a style that shows the station and elevation. I want the elevation to reference the profile. But it only gives me the elevation of the surface and I need the top of pipe elevation.
I tried crate profile by layout and traced over the top of the pipe in profile but its 3 miles and it will take a long time. How to get what I want done faster?
why my text is vertically oriented when I'm doing a preview of my layout? Plus, I'd like to know why when I set greyscales on my CTB only hatches and not my lines are displaying in black & white? (on my second layout)
I've created a surface from blocks but I need to move many of the blocks to new locations/elevations but if one of the blocks that formed part of the surface build is moved or elevation adjusted the surface doesn't update. I have to reselect and add the blocks to the definition, remove the original blocks and shunt the newly added block up the definitions list.
If Civil points are moved they automatically update the surface (as expected) so is there a list anywhere or which entities/objects will cause the surface to update automatically and which ones won't??
I don't generally get data in this way hence the question so I'm thinking the best way forward would be to convert to Civil Points and make point groups??

I've got a very long narrow site where more of it would be better shown and printed on a vertical page. However all the default and custom viewports are designed specifically for horizontal pages. How can a page be rotated to be plotted vertically?
I want to know the correct way to find the offset origin of a layout in an AutoCAD drawing. Let say I have a drawing that has many items on it. And I create a layout showing just the items in the lower right corner of the drawing. I want to know the offset origin of this layout relative to the Model space.
I came across some LISP commands that are supposed to do just that:
