AutoCad 3D :: Creating Surface For Road At Section

Oct 9, 2013

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)

AutoCAD Civil 3D :: Surface Creation Or Section Views Creating Random Lines

Jun 15, 2012

I'm uploading the .dwg and .txt files.  I'm trying to get volume calcs cut and fill between two surfaces and when I compare the data between AGTEK's Highway 3D there is different results.  I looked into it to find these random line appearing in Autocad making what seems to be the problem.  Where are these coming from and how do I fix? Also, if you could anwser how can I insert a sectional following the 12'-23' offsets and dropping 1.16' down and adding it to my design surface. I want to make a big box there added to design surface.

AutoCAD Civil 3D :: Road Surface Becoming Flat?

Jan 30, 2013

running an assembly in to the road corridor and creating a surface. i have designed a network of Roads in CIVIL 3d in which whole network is surrounded by a Loop road. The loop road cross fall is unidirectional (2%) and 4.5 wide. I have used LaneOutsideSuperWithWidening subassembly to create  the assembly of the road. This doesnt contain any kerb or footpath but only road channel lines, The corridor run soomthly but after creating the of the loop road corridor the surface is becoming flat meaning there isn't any cross fall acoss the road but in the assembly crossfall is there. If i run the same assembly in another road alignment the suface is coming absolutely correct.

I also tried different road assemblies to run along the loop road but the result is same no cross fall across the road.

AutoCad 3D :: Moving 3D Objects In Relation To Road Surface

Oct 7, 2013

I use geophysical software which exports 3D objects to AutoCad in relation to the flat surface - "zero" level. Most often clients want to get results in local height datum (in relation to the road surface which has usually slope and is never perfectly flat).

Is there any method to move all objects automatically and show them in relation to the road surface? Ideally I would like to define road surface with three lines (two side lines and center line). Is there any plugin to AutoCad that can do it? If this operation goes beyond the possibilities of AutoCad, can you recommend me a software (eg. AutoCAD Civil), which automates the process?

AutoCAD Civil 3D :: Creating P&P Sheets For Road

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.

AutoCAD Civil 3D :: Creating Section Sheets From Multiple Section Views

May 21, 2012

When i am creating section sheets from multiple section views ,section sheet  view port scale  changes.I did set it correctly in my template.

For example it changs from 1:150 to 1:150_1 

Then in section sheets scetions views are not displaying correctly.

When i change view port scale manually it shows correctly.But it should do to all sheets.

What should I do?

In model spacr multiple section views are showing correctly.

AutoCad 3D :: Creating Section Plane To Get Cross Section

May 13, 2013

I am using AutoCAD 2013

My solid model is imported from IGES file format. I'd like to make a plane at specified location (perpendicular from the surface), and I'd like to have a cross sectional geometry cut by that plane. (attached pic.)

1. How can I make a plane following perpendicular line from the surface?
2. How can I export the cross sectional geometry?

AutoCAD Civil 3D :: Creating Subset Surface From Main Surface

Sep 15, 2013

I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.

i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline.  This seemed to work, but  when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.

AutoCAD Civil 3D :: Labeling Surface Section

Oct 8, 2013

I want to label the surface sections (eg, fg) in a single location something like what is shown in the attached image.

Currently I am using a major offset label which refers to the surface description* where the surface name is stored. I set the increment to a suitable number which results in multiple labels along the section. I then drag one into position and delete the rest using ctrl-select. While it would be far easier to use multileaders to acheive the correct look, they don't update location with the section views.

We use the description to store the 'friendly' name as our object naming standard wouldn't necessarily make sense to the viewer of the plans.

AutoCAD Civil 3D :: Surface Data On Section Views Disappeared

Apr 8, 2013

I created some about 20 cross sections for a creek we topo'd and then went to work making the topo itself look presentable. After I was all done with that I noticed my cross sections had lost the surface data and were now just an empty grid.

When I go to edit a cross section's properties in the elevation tab the "Automatic" choice has a minimum and maximum elevation of 0. When I use one of those existing sample lines to create a single cross section the same thing happens, it's not picking up data from the surface. However, when I made a new sample line along the existing alignment it picked up the elevations and created a cross section just fine.

Is there anything I can do besides recreating all the sample lines and cross sections? I'm looking for any other way because I have already labled and put in some extra work on the cross sections and I'm hoping to be able to just recreate what I already did and drop them so it will match the linework I already did.

AutoCAD Civil 3D :: Section Labels From Surface Features Lines

Jun 27, 2012

Often we  build a design surface from feature lines and possibly a grading or two. Then we cut sections.

Now, for set out, and especially for smaller contractors who don't have fancy survey gear, it would be really nice to be able to show design surface levels in section bands BUT ONLY AT THE SURFACE-DEFINING FEATURE LINE LOCATIONS.

I am aware that we can use grade breaks...but this gives us band data at each triangle intercept which is too much data. We can weed this data, but that is indiscriminate and I really need only the data at the surface-defining geometry points (feature line locations.)

We can also use station/elevation labels on the section views but this is time-consuming and non-dynamic. Band labels are dynamic and more or less automatic...if only we could get the discrete locations we need labelled.

AutoCAD Civil 3D :: Create A Profile Or Section Using Network Surface?

Mar 27, 2013

I have in front of me a survey of a small section of road (it's only 10m x10m or something). I want to be able to create a profile along the road section to demonstrate the surface level changes. I have created a network surface but Civ3D doesn't seem to able to use this type of surface to create a profile. Is there anything I can do, perhaps a way of transforming the network surface into another type of surface? Or am I going to have to manually create this profile in ACAD!

AutoCAD Civil 3D :: Creating Cross Section Sheets

Dec 8, 2012

After I create cross section sheets (Output---> generate cross section), the generated sections do not fit in the sheet exactly. In fact, the generated layouts do not cover the sections correctly, and some sections fall outside the created sheet.

It should be noted that I use the "ISO A1 Section 1 to 500" layout which is installed on the default pass of C3D (template folder), and the scale of "view section style" is  set to 1/500. I tried the scale of the drawing (toolspace window---> setting tab---> rigth click on the name of drawing and click edit drawing setting) with 1/500, however the problem was not solved.

Another important issue is that the section views in the "Model space" are shown correctly, but my problem is in the layout space after generating cross sections.
