AutoCAD Civil 3D :: How To Create Two Offset Alignments
Aug 10, 2012
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 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
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]
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'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 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 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.
How do I project the Proposed Road Level information from Road_1 at the intersection of Road_2 (Alignment_GA.jpg) onto the Start of the Profile for Road_2 (Alignment_Profile.jpg) to give me my tie in start point?
How do I obtain the exact change of the intersection Point? How can i extend Road_2 onto the horizontal curve of Road_1 so i know they exactly intersect?
I have two alignments that are not parallel that make up one corridor. Each alignment has a separate profile running along it. At stations where I have a template drop in my section editor, it is not representing what is really happening because it just is perpendicular to one alignment. Is there a way to develop a secondary alignment that will have my section editor show what will be parallel to both alignments.
I am using Civil 3d 2012. What I have is a surface along railroad tracks. Each set of tracks has a different alignment because they aren't parallel. I have a baseline alignment with my stationing set on that. What I want to do is have one profile view showing the multiple track alignments based on the baseline alignment. I can't use the offset alignment because they aren't parallel.
I created an alignment from the arcs at my intersections. When I go to the geometry editor under grid view it only shows the first curve.Does c3d support discontinuous alignments? When building edge of pavements at intersections is the workflow to make a new alignment for each intersection?
I cant get this one. I have created an alignment in a drawing and created a shortcut. When I data shortcut that alignment into drawing "A", its all good. Alignment starts at station 10+00. When I do the same data shortcut into drawing "B" the alignment is starting at station 0+83.33. Why?
I need to put a reverse curve on an alignment. I have tried using two free curve fillets,(between two entities, radius). the first curve was fine, but it would not allow the second curve. I also tried using a floating curve ( from entity radius through point) first, but it did not work.
Loving Pressure Pipes so far, taking us a bit to get them setup to work the way we want.
Using Pressure Pipes to design two water mains, the first main is a straight run, and the second one starts off of a Tee that I added to the first. This part seems to be working fine, now when I go back and use the Create Alignment from Pressure Network to create the alignment for the first main everything seems fine, but the second one is where I am running into my problem. When creating it, if I don’t select the Tee that I used as the starting point the two alignments don’t intersect, however if I do select it something crazy happens, my start point for my second alignment snaps to 0,0 instead of the Tee. I have tried a couple of different times with both Tees and Crosses. I get a little bit of a different result with Crosses, if the cross is the start Point of the alignment it behaves the same as a Tee, snapping to 0,0, however if the alignment goes through the Cross it is created correctly.
We have a main line (1 Alignment) and some junctions on that main line (other Alignments), and out GOAL is to create GL (General Layout) sheets, showing Shading, Setting out and Dimensions..ETC.So every VFG (View Frame Group) i can generate cut sheets from it, the Question is
1- How can i "connect" all the VFGs you see in the image attached into one VFG so that i would create them together ?
2- OR should i make separate VFGs like you see i did already , and then create cut sheets for each VFG ?
Any way to label the slope stationing rather than horizontal stationing? This is common when doing long pipeline projects (40 miles) or more in very steep terrain. I am doing one now that is only 1 mile and the 2D verses 3D length is a difference of 100'. 40 miles that would mean it would be off 4000'. The client uses this stationing as a guide to know how much pipe they need. If you would do that horizontally that would be way off the mark.
I am using Civil 3D 2010? Maybe its included in 2012 or could that possibly be an option for future releases since it is a 3D software.
When I have a street centerline alignment, I am failing to see any benefit. If I have a change, I want the change, not any old stuff. If I have a need to different alignments for differing purposes, I'd rather give each my own unique name. If I make a change, and I want that change easily reflected into a profile or corridor, wouldn't it be more efficient to let the name remain constant?
I am currently trying to xref a Civil 3d files into auto cad 2d. So far on the model space it works fine however when i try to put it into paper space the labels on the profiles just seems to go crazy. See the attached picture. (First picture where the label are not displaying correctly in paper space and second drawing in model space of the same drawing which shows the labels correctly).
I believe its the annotation that civil 3d uses to generate these text labels but i am unaware of how this can be solved.
At our office We use alignments to designate the pipeline. At our pi.'s or points of intersection We have the autocrat _wipeout circle. It works fine in c3d 2011, but for some reason when We take them into c3d 2012 the wipeout circle goes under the red line instead of above. We have checked through the properties and can not find a display order. Otherwise We are currently inserting a wipeout circle and having to place on At every intersection.
We have a HUGE number of data referenced surfaces and alignments that need to be moved to a different group of folders. Is there a simple way to do this without breaking the references (each surface/alignment) is referenced into multiple drawings.
The project was divided up into a bunch of little mini projects so now we have 500150_A, 500150_B etc (around 90 of them). Each one has a dwg file with a surface and at least one alignment and that drawing is data referenced to all the other sheets within that mini project. Each project has _Shortcuts, drawings etc.
The powers-that-be have decided to 1) change the project number (from 500150 to 500152) and 2) to bring all these mini projects together into ONE project.
We've confirmed that each surface/alignment has a unique name which means that there shouldn't be a conflict in that regard.
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.
