AutoCad 2D :: Creating Road Centerline To Make Into Alignment
Jul 20, 2012
So today I was creating a road centerline to make into an alignment. The road has many curves. So I was making circles and connecting them with lines while snapping from tangent to tangent. So far, so good.
Went I go to trim the circles using the lines I drew tangent to tangent, it says that there are no intersecting edges. WTF? When I zoom way in, the line is not touching the circle. Now, I know that visually that is NBD. When I run a distance check, snapping from endpoint to perpendicular, there is a measurement of zero. UGH!
So to get work done I've been having to break the circle and the 2 points, then erase the rest. This is such a PITA and I've never had anything like this happen.
P.S. I'm running Civil 3D 2013.
The top line is the circle, the bottom is the line tangent to it.

I have a road with storm drain and sanitary sewer. There are three alignments, one for the road centerline, one for the sanitary sewer and one for the storm drain. I would like to label the structures with the stationing from the alignment it's on but I would also like the label to include the road centerline station perpendicular to the structure.
Something like this:
SS-MH #4
Sta. 10+00
=Road Sta. xx+xx

I've created a copy of my centerline alignment using the "Create Alignment from Existing Alignment" and was going to edit the new alignment to explore different options. But the new alignment can't be editted. It's lost something in the translation. There is no grip edit for the PI, that the original alignment has.

I am working on Street Improvement Plan using Civil 3D 2012. I have my centerline stationing set for major (100') and minor (50'). My street plan is kind of busy with a several call-out/label, leader etc. I want to set my my station for both major and minor with with decimal to read as 1+00 or 1+ 50 as opposed to 1+00.00... How to get rid of the decimal points.

I cannot get a 'centerline' (symbols panel/centerline) to create. I can use all the others (centerline bisector, centermark and centered pattern) without fail. This first one (with the single line) does not EVER give me the option to 'create' when I am done clicking my points, its always greyed out and I dont know why.
how to make a centerline...select that option, click here, click there, when done right click and 'create'. Doesnt work.

I am creating P&P sheets for my road. I created view frames, and when I got to create sheets, I pick "all layouts in new drawing". I go to open the new drawing up, but all that shows up/tranfers is the profile and alignment, nothing else comes over ( proposed linework, existing linework, etc.)??????

I am having difficulty in creating a surface for my road in 3d at this section, the points given are along the center lines and so far have been fairly straight forward for the fall of the road as there have been no junction up until now.
I am not using 3dpoly at this point, just plain old lines.
Road 1 displays where i am having issues and Road 2 display how it looks in 2d format (only at an angle)

i have a road layout consisting of 3D ploylines. i want to create a surface over this layout.... i have tried but it will only seem to work on straight sections of road and not the intersections.. And i know it would be simple in civil 3d but i dont have access to that.

I have this intersection and I want to make a roundabout there. The first step is to make two center lines of the roads. How can I make these centre lines perfectly aligned? The lines that you see in the attachment are freehand made.

I have the centerline of a berm constructed using a 3D polyline. I want to use this centerline as the Alignment that I need from which to create a Corridor. When I try to create an Alignment from objects, I can only use a 2D polyline, not 3D. The berm has a slope to it and I need to have the assembly follow that slope as I create the Corridor. Do I need to create the Alignment in 2D and then edit the points for elevation?

Creating points at the stations of an alignment,
I wanted to get the (x,y,z) of the stations of an alignment, but sounds not to work.
In the screenshots below, I got the message “The specified station is not valid for this object” and couldn’t proceed!

I've been asked to create a 3D poly from a given alignment and profile.
The only way I know to do it, is to create a feature line using the "createfeaturelinefromalign" command and exploding it.
My problem is that the resulting 3D poly loses a lot of the "precision" the feature line had (how closely it followed the alignment).
another way to create a 3D poly or of some method of maintaining the feature precision when exploding it?

I am trying to create a closed loop alignment for a track. Previously i have included a small gap between two alignments to get around the problem when a housing plot is created (see the attached dicument) when a closed alignment is created, Is there any way of getting rid of this?

Having a rough time with Pipe Networks! I am working an example from the Mastering C3D book (P. 371) as in the following steps:
1.Clicked SS structure(16)
2.Selected Create Alignment from Network on ribbon
3.Selected last structure(18), hit Enter
4.Changed options as needed in Create Align from Network - Create Profile and Profile View check box: Selected
5.Changed options and clicked Create Profile View
At this point the program pauses, then a dialog box trys to partially fill the screen but is all white then fades away as fast as it appeared and I'm stuck with a paperweight that beeps at me everytime I click the mouse, no panning or zooming response at this time. The command line is prompting me for the profile origin. I can switch to other apps and bring up TM and when I attempt to end C3D then it tells me that it can't because waiting for response. I can then cancel the prompt to save the drawing and C3D exits the active command and control is returned.

It can be done using the LaneFromTaperedMedian subassembly, and that there is a webcast explaining it. I have checked with Autodesk, and the webcast is no longer available. Any detailed instructions as to how to accomplish this. I'll attach an image of my median.

I'm drawing individual guest rooms for a hotel that I would like to xref into the main floor plans. The walls between the rooms are 8" wide. I would like to only show half the width of those walls (4") so when xrefed againt another guest room in the main floor plan, the total width would be 8". But I would like for the one side of the 4" wall to appear as a centerline on the individual plans, but at the same time, be able to shut the centerlines off on the main floor plans. I'm new to ACA 2012 and perhaps I'm going about this in the wrong way.........?????

I have a ratchet plate idw that I've drawn and dimensioned, but I would like to insert two bolt circles to the two diameter dimensions that appear to be pointing at nothing. The circular pattern is not made up of circles so I haven't been able to use the Centered Pattern command in the centerline section. I'm using Inventor 2013.

I am doing a small drawing with bolts and nuts. I wish to show the centerline visible, but with CENTER2, and selecting the line for Property, I changed the Linetype scale to .25. However, the actual line on the drawing doesn't show a centerline but a continuous line. See, figures below. I wonder if the gaps between the small dash and the long lines can be increased.

When a corridor has lots of variations along the outside edges of the travelway it can make corridor modeling from the centerline a cumbersome task. This is because we have to create a template and region for every scenario where the edge treatment varies from right to left.
To simplify the process I have considered creating alignments for the edges of the roadway and adding them as baselines to the corridor. This way we can create just a few assemblies for the various edge treatments and apply them independently to the left and right baselines. These assemblies would then target the centerline profile to model the crown of the roadway, just as we do for curb returns.
In my experiments it seems to work nicely, but I encountered problems when viewing cross sections and calculating quantities, since the software is designed to work from the centerline baseline. Would it make the sections work if I add an assembly to the center baseline with short segments of pavement and stretch them to the edge baselines?
Another challenge is generating the profiles for the edge of the roadway to use for the baselines. These profiles would need to follow the centerline at a given vertical offset to provide the desired crown slope. Any edits to the centerline profile would need to be reflected in the edge profiles. This could be done by creating a surface from a grading object that is built on a featureline generated from the centerline and using that surface profile for the edge of roadway baselines. Another would be to stretch the center assembly to the edge and generate a profile that way.
So my question is: can this workflow be made to work somehow?

I have problem with placing origin of ordinate dimensions on point where two centerlines are intersecting.
In my particular case I have rectangle and centerlines are in the middle of pararel edges. So they are crossing eatch other in the center of rectangle.
I need to place origin for ordinate dimensions in this point. But till now I had not find any way to do that except make a skkech and draw a line that's one end is exactly in the point I want. But it seems to me like rather ridicules aolution.

i've made a serpantine curve that starts from one line of alignment and end on the other line.
i wanted to know how can c change alignment direction when these two feature line and alignment meet each other in order to change the alignment path?

I using a data reference/shortcut to properly label an alignment in paperspace. However when I reference the alignment in and apply the labels the aren't the same as the original alignment that I am referencing. Is there a setting where I am supposed to apply a new beginning station.
Also it seems as though the stationing(distance) isn't even matching up 1:1 with the original drawing. For example in the original base drawing my alignment starts at 10+00 with the next PI at 14+76.98, but the stationing on the reference alignment starts at 0+83.33 with the very same PI being labeled as 1+23.08. So the very same distance is 476.98' in the real design and the drawing it's being referenced in, but the stationing of the referenced alignment shows it as 39.75 Units.
I've attached a screen of the beginning of the alignment.
