AutoCAD 2013 :: Make Center Line Of Road
Oct 27, 2013
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 need to project a crossing pipe onto a road centerline. I have water running down one side of the road 7' off the centerline of the road and sewer running down the other 8' off the centerline. There is storm drain running perpendicular across the road.
The sewer and the water are projected onto the centerline of road profile. When I draw the crossing pipes in that profile view and change the override, because it does not cross the centerline, it disappears from the profile view. How can I accurately show the crossing at the proper invert of the respective crossing without drawing the ellipses manually?

When I click on line command and then draw a line on my screen it will not identify the center of the line. That is it will not show green triangle on line.

Is there a way to make an outline that is either only on the inside or the outside of the center line of the outline? I know that the default in Corel is to center the outline on the center line of the outline.

I'm new to Illustrator and perhaps it's not the best software of CS6 Master for doing this, but:
I have a few (13) circles, they are connected with lines (one line from the centre of a circle to the centre of the next one, so 13 connecting lines). I need to move the circles around in order to create the appearance that suits me best, but I want the connecting ending to move together (see picture below). I need to do this often and get an immediate visual feedback. How do I do it? Am I using the wrong software altogether?

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 made an alignment of road, inserted with sample line, then i made a profile. But on the sample line on profile, there is not a data of height and lenght of profile. How to get those data in road profile. I can manually draw that, but i think there is an easier way?

In the attachment you can find a drawing of a roundabout.
why the give way road markings are much more and much smaller in my viewport? Also I can't see the letters A, B, and C in my viewport. Why is that and how can I fix this two things?

I have an FDO layer which I am styling like so:
Concat ( FDO_LAYER1, Concat ( '
', FDO_LAYER2 ) )
This layer is styled so that all text is centered. In this case, FDO_LAYER2 is having it's text left aligned. I'm pretty sure this is due to the method I am using for a new line. Is there something else I can use to break the line and maintain the center styling?
Using a second point for FDO_LAYER2 is not an option.

I'm trying to plot routes on a road map. A monochrome map is on the background layer and the routes are to go on a transparent routes layer.
I draw the routes with the pencil tool, holding down shift to go from node to node. The pencil opacity is set to 60% so that the road names on the background layer remain visible through the route colour.
All works except that the nodes are higher in saturation than the links between. What seems to be happening is that the adjacent segments overlap at the nodes and the saturations add together.
How to colour in the routes with a consistent saturation?

I have got a 2D profile set up for new drawings. When l start a new 2D drawing l just save as and then start the drawing. This time l found all my Solid Lines and my Hidden Lines are all coming out has Center Lines. All are loaded right. What have l done and not realize.

I am taking my first semester and my instructor is not very good. I have a circle that I have arrayed 3 smaller circles on. On 4 of the circles I need to rotate the centerlines about 45 degrees. Is there a way to rotate these?

I have been practicing using a older book(copyright 1990) and it has some decent exercises in it. I was able to do this one but it seems I can"t find the proper way to do this..First drawing a line a certain distance..ortho on,click the first point anywhere,move curser to the left and click again. that gives me a line at 180 degrees at what ever length..Line command again starting at the second point of the first line..after clicking that point,I type in @2.38<150 that gives me a line2.38 long at 150 degrees..now how do i make a third line relative to the second line so that the angle is 75 degrees and a certain length..the picture shows what I am trying to draw..using the polar cordinates you get an angle based off the UCS( which is set at world) when you try to draw the third line ..that makes the angle between line 2 an 3 not the angle that I want..To make the drawing,I rotated the ucs -30 degrees..But there has to be a better way than that..

I draw a curved line and would like it to remain as a curved line even after saving the file. However everytime after saving, and opening the file again, the curve breaks into many line segments, which is not what I want! I want the curved line that I draw to remain as a curved line even after saving and opening. How do I do that? I am using autocad2010.
I use the ARC command to draw a couple of lines, they look okay here. But after I saved it, and re-open it again, what previously appeared as curved lines changed in their appearance to polyline segments.

I need a creative way to do something I know can be done in SW and Pro-E but as far as I know can not be done in Inventor to date
I am using the origin center line and semitry to control a box and its associated geometry and want to control the position or offset of a second box relitive to the first using a center line associated to the second box with a dimension. Problem is that the dim will only control its off set position relitive to the initial side from which the dim was placed. I.E. if the dim is placed when the CL of the second box is to the right it can not be moved to the left (what would in essence be a -dim condition) understandably Inventor does not like that but SW and Pro-E can use there little wheel and roll it down to 0 and then back up to a + dim in the opposit or in this case Left direction.
I know that I could place a dim off the interior wall of my first box geometry and associate it to the CL of the second box but the math to that may or may not be appropreatly effective in other words in condition A it may need to be 1/3 of d1 and in condition B it may need to be 2/3's of d1 or some other dimension.
I would love to be able to do this via iLogic or perhaps something to do with the placement relitive to a construction geometry utilizing a circle but so far I have not found a viable solution.

how to put a center line on an open ended slot. Say in the front view you can see the radius of the slot with horizontal tangents running to the end of the object; this isn't the problem. When creating the top view, you only see one hidden line indicating the arch, but the other side is just open to the end. You have no means of finding bisectors.
I've added a jpg file, looking for the center line in the top view.

I have problem with medians ( Both MedianRaisedWithCrown and MedianRaisedConstantSlope) when crossing center line ( i.e whole median has to cross the center line).
I have median that goes along the centerline and it has to move to left completely ( whole median is on left side of the centerline) to cater for left turn. I tried with MedianRaisedWithCrown and MedianRaisedConstantSlope but it did not workout for me.
I used alignment ( for cl ) and offset alignments for median edge and etw. I have problem when the median edge ( offset alignment ) cross the center line and continues. I can see etw and median feature line shifts.

I created a 2d drawing of a river I am building and constructed a centerline. I already have a surface of the existing ground created from which i created an alignment of the centerline and created a profile showing the existing grade along the centerline. Then I created another alignment on the same profile which shows the bottom of my river that I want. I now want to calculate the cut and fill of my project but don't know how. Is there a way I can create a surface of my river from my profile? Or what process do I follow to apply my centerline profile to my 2d river.

For example, I'm making revisions to a plan and drag a block or xref of the floor plan changes where walls/doors/windows have moved. I want to be able to simply pick the underlying linework as opposed to tracing over each line of said xref/block.

I'm wondering if there is a way to annotate from the origin without having a long diminsion line to the center. (see image) I want it like the 'linear diameter' but not with double my size. I always have to annotate the projection from center and this would be easy much more easy to do.

If I have a series of lines on a layer, is it possible for a macro to place a label for the lengths of the lines at the center of each line in AutoCAD LT 2012? Adding a DIMLINEAR to each line is for the birds....my drawings have as many as 250-300 lines that need to be labeled with thier lengths.......
