AutoCAD Civil 3D :: To Create Tangents (VIPs) On Desired Chainages And Elevation
Dec 7, 2013
I'm new in Civil 3d, just learning by myslef by following tutorials, I've a provlem, after creating existing profile, when I'm going to create design profile I want to draw tangents(VIPs) on my desired chainages and elevation by given command, specify start point and I write 0,376.00 0 means chainage 0+000 and 376.00 is elevation but civil 3d shows a message "point is ouside profile view try again.
I am trying to create an elevation label that will give me the spot elevation followed by the letters "TC" and then on the line below subtract 4 inches from the elevation followed by the letters "BC". It's easy enogh to add the letters but the simple equation of elevation - 4 inches eludes me.
I have a number of Sites in my drawing. I want to be able to set a Site current (in LISP) so that when you create or draw a feature line, the site is set to the desired value. I haven't seen a variable or setting for this.
Is there a way to delete multiple VIP's in a profile? By windowing maybe? I have a profile with several hundred VIP's and I need to delete the VIP's between certain chainage but I'm not clear if this is possible. It will take hours to delete them one by one, although as far as I can ascertain this is the only way.
I created a new alignment based on a survey topo. The first half of the alignment shows the sections/chainages but the second half does not. My alignment should be line, curve, line, line, curve, line, line, curve, line but when I check the design editor, it only shows the 5 elements. When I check the sub entity it appears some are not assigned numbers which have generated a warning symbol.
When we are producing cross sections through our surfaces, the chainages are every 10m, and the level at these chainages. This is fine in some cases, but when you have batter slopes, you want a level at the top of slope, and bottom of slope. How do you get the chainages at these areas. I have attached a sample image, showing a dashed line where I want a chainage and level in the bands. Is there a way to do this?
EDIT: The attached section is produced from an alignment through the surfaces,
I have gone thtough alot of articles here on how to create an alignment from 3D polyline. Most of them talk about creating a profile by creating a surface. But in my case I have a 400km 3d polyline that represents the pipeline centerline. I need to create an alignment showing slack (3D) chainages. Which means I need to create alignment from the 3D polyline. Is there any way to do that?
I created a new surface, pasted my OG surface into it, set the build to exclude elevations less than and greater than but my surface still is showing every contour range. I want to only show contours at elevations of 371.5 and 370.5
how to get 2013 C3D to create a large watershed with a big elevation drop? Arcview can do it, but I bought the new version of AutoCad, which meant a new computer, instead of the Arcview extension and I don't see it happening.
I'm having trouble designing an alignment from an pre existing road. I drew the polyline and I need it to get curved between tangents (since there isn't a label that informs the angles between these tangents). But when I do it, not all the tangents get curved, just a part of it. The weird thing is that the whole polyline gets converted to an alignment and labeled correctly, but only the tangents near the initial stations get curved.
Other issue is that even if I draw another alignment in the same X, Y, i can't project it to my existing profile view. I can't offset my EG so i can weed it and design my alignment for my pressure pipe.
I'm more experienced working with pound and slopes in architecture design and this part of C3D seems more complicated
I am working on a large park project. I have a proposed and existing surface. I have created a volume surface to show elevation banding with cut and fill ranges. I need to create a drawing for someone who doesn't have civil 3d showing all the "cut" areas. They really want a boundary of hatch. What is the best way to do this after I change my analysis to -30 feet cut to 0 feet cut.
I use adobe photoshop lightroom 3.6, earlier i was able to export photos to my desired folders in desired format but i am not at all able to export any photos at all!
I always draw a polyline to define my alignments. When selecting the polyline for the alignment, in the Create Alignment from Objects box, at the bottom, the default is to "Add curves between tangents". Where do I turn that off so default in NO.
I am trying to work a routine that will draw tangents with or without curve in a profile by calling the command in the Toolbar icon to "Draw Tangents" button that is on the Profile Layout Tools toolbar. I can't seem to locate the command that I could execute at the comand line or in LISP. Where can I find a complete list of C3D commands to reference?
When I snap a point to an object, the point takes on the elevation of the object. I would rather the point's elevation stay as is.

A few weeks ago I did not have this problem but once my computer was switched to the company's global server and c3d was reinstalled the problem appeared. Furthermore (post switchover), when a colleage of mine prepared a simple test drawing with just a line and a point, he was able to snap to that line without the point changing elevation. When he sent that drawing to me and I tried snapping the point to the object, the same problem occured with the point taking the elevation of the line object. I suspect it is a system variable issue
i have some existing drainage pipe and structures in a base plan that i need to change the invert (which is the easy part) and the top elevation to the existing top elevation that does not meet the minimum presect in civil 3d 2012 is there a way to change these min. to match my exisitng elevation for example i have a catch basin invert is 15.45 top is 17.56 with a 18" rcp the cover will be less than 12" and i need to change this.
I am in case to model a stormwater network contain ditches with irregular sections, open channels and closed pipes in SSA. I do not have access to IDF curves for the Project area. We got a weather station in site which is giving us continuous data from last 3 months till now. At this stage we just decided to use certain Rainfall intensity (mm/hr).
We got some check points to check the turbidity. What I need to know after analyse is i.e what is the flow at these points at 6:00 pm if we experience the rainfall from 3:00 pm to 4:00 pm with 20 mm/hr rainfall intensity.
So my concerns are with these available basic data, which method is suitable? and as long as we approach more valued data from in site weather station then which method will be the best. If i want to input time of concentration manually for each subbasin then how can i input TC of pipes or channels in SSA? URL....
where MATT said: "SSA does not calculate the Standard-Step method. The Rational Methods (including modified, and DeKalb) all compute the runoff to the inlet or junction. As soon as runoff enters the system, continuity and momentum calculations take over. SInce you are using Steady State Qin = Qout, so no routing occurs on pipes."
how do i understand the flow in certain points i.e 2 hrs after the rainfall is finished if I can not define TC for pipes or channels?
I am trying to create a property definition that will display the elevation of a space object. I looked through the automatic properties and did not find anything that looked like the elevation.
I have tried the following but was unable to achieve any success.
RESULT="--" On Error Resume Next Set AcadApp = GetObject(, "AutoCAD.Application") Set Obj = AcadApp.Activedocument.Objectidtoobject("[ObjectID]") RESULT = Obj.elevation
That formula does work if i swap elevation with say height, width,length or any of the properties found in the automatic property list that are a single word. I know the elevation is there I just don't know how to access it.
This might be simple, but what is the best way to hatch a part of a surface at say RL4.00 only so that any part of the surface below RL4.00 is hatched and the rest of the surface is not.
I used the Volume dashboard to cal volume so when I view the surface in object viewer or 3D I see my TIN volumes surface at zero elevation is this right? I think the reason is because they want us to see both surface so they are not on top of one to another.
Any way to label the elevation of an object where it is picked? For example, I'd like to be able to pick on the node of a feature line or 3D polyline (or any object really) and have a label placed that displays the elevation of the object at the point where it was picked. This could appear similar to the surface spot elevation label, but instead of getting it's elevation from a surface, it would come from the object where picked.
Alternatively, any way to create a label style, perhaps using the Note label, to display something like this? I don't even care if it is dynamic or not, static would be fine. However, I do need it to scale innovatively . Tool Pac has a feature that does this, but the label is just a polyline and text that is not annotative.
In the good old days I would create 3d polylines by elevation to create curb lines and driveway cuts. The command was in the terrain pull down. Has this feature been completely down away with?
Superelevation curve criteria specifies axis of rotation but the assembly does not contain pivots.
okay i got this Before , just when i wanted to change in the Super Elevation Wizard , to outside lane rotation , i recently used AOR type , but yet no luck. also in my profile the super elevation the Cross slop Band : i always no matter what a rotation about center line.
