AutoCAD Civil 3D :: View - Visualization Of Corridors With Multiple Baselines Or Intersections
Aug 28, 2012
I created a simple roundabout in Civil3D with the intent on visualizing the corridor in 3DS Max Design using the Civil View plugin. The corridor rendered complete in Civil 3D, but there are large corridor gaps in Civil View. They all appear to be at the location of corridor baseline boundaries. Obviously this is a non-starter, as 3DS Max is supposed to improve the visual quality, not reduce.
Attached are some sample images of the roundabout in Civil3D and in 3DS Max Design.
I am using Civil 3D 2012 and 3DS Max Design 2012.

What is the advantage of creating a seperate corridor for an intersection? Doing so requires leaving gaps in the road corridors at the intersections which creates a mess in the surface triangulation through the gap. I know we can clean it up by creating a composite surface and pasting all the pieces together but how tediious that is!
I was wanting to keep the intersections as seperate corridors because if we add them to the road corridor we end up with numerous duplicate baselines which makes editing and data management a nightmare.This whole process is a huge time consumer. I can't understand how Autodesk expects DOT's to adopt this software with this workflow.

I've created a T intersection and have created the surface for the T corridor and the entering side road. The surfaces appear correct. When I create a surface for the main road, which has been split into two regions, the surface goes thru the T corridor. How do I create a surface that simply goes up to the T intersection and picks up again after the T intersection?

Heres the issue;
I created my main corridor which is a 4 lane arterial with ditching on both sides targeted to my prelim surface. On my main corridor i have several intersections and approaches which i created intersections for and set the targets so they are correct, i also created secondary roads for all intersections. Now that it is visually correct there is a few things i would like to do.
1) Combine all intersections to my main corridor and create surface for adjusted volumes.
2) Raise combined corridor and intersections to adjust cuts / fills so that all attached intersection and adjacent corridors adjust with the main corridor.
Do i have to go to my main corridor profile and move each curve and tangent separately, then check all other profiles and intersection to insure everything has been adjusted?

I am doing bulk earthworks with C3D 2013 and quite often I am modeling large dam walls with multiple raises, core sections, filter layers, etc so I end up with up to 50 surface models in one drawing. The process I follow involves modeling each raise of the wall by targeting an elevation 10 metres or so below NSL. I then use a volume surface to give me the intersecting boundary between the topography surface and the wall raise surface. I repeat this process for each raise/core/filter section - create volume surface to find intersection, extract boundary of intersecting volume surface, add boundary to wall raise surface, put both on a unique layer calculate volume - repeat for next wall raise - ad nauseum.
To speed things up a previous draftsperson created a shortcut button on the ribbon that does the volume surface trick with one click so all i need to do is hit the button, select topo, select wall raise and it gives me the volume surface between the two, all i need to do is extract the border and add it as an outer boundary to the wall raise. I would like to take this to the next level if possible and this is where I an stuck.
If my drawing consisted of a topography surface and "X" number of wall raise surfaces all named in a uniform fashion ascending numerically or alphabetically would it be possible to write a routine/shortcut button that did the following;
1.) Create a volume surface between topo & wall surface 1 - extract border as polyline - add polyline as outer boundary to wall surface 1 - move both wall surface 1 and newly created boundary polyline to unique layer.
2.) Repeat process for topo and wall surface 2
3.) Repeat process for topo and wall surface 3
.....and so on until all wall surfaces have had volume surfaces created between them and the topo?

I am trying to set up a corridor with multiple materials with multiple pavement sections. For example, I have concrete and asphalt surface pavement, about 4 different kinds of base material and 2 different sub base materials to use. It doesn't seem like you can get quantities divided up like that. It seems like you can only get the 'base' material counted up with the quantities and you can only assign one material to it. Is the answer to create multiple corridors for each pavement type that has their own Code Set to assign to each corridor?

I have created several different corridors (with different assemblies in them), but when I to to view sections the same assembly keeps showing up. How do the sections get updated with the new assemblies?

I am doing some car park designs with Corridors at the moment.
The method I am using is to create a dummy surface and apply surface profiles to all Baselines and Targets (mostly Offset Alignments). This way if I have to change my levels, I simply amend my dummy surface and everything updates straight away.
This works great, but I recently got a (typically random) Fatal Error. I recovered the Recover drawing which was saved and for some reason all profiles changed to Static and I can't change them back to Dynamic.
I know that if an alignment cant find the surface it will change to Static and I assume that during the fatal error or recover process, something must have triggered for this to happen?
Is there any way (other than resampling all profiles and updating each corridor target individually) of making the profiles dynamic again?

I need to know if there is a simpler way of adding points to a string 3D polylines which are intersected with multiple 3D faces.

I am trying to create a linetype with a 3d shape included to represent road markings, i.e. central lines and edges etc.
For this I need a .shx file and I don't know how to create this as I am not allowed to select 3d objects when using the MKSHAPE command.
How can I best create a linetype with 3d objects?

My knowledge is that there are two ways of rendering and visualizing corridor. One by Code Set Style; the other by Corridor Surfaces and Corridor Surface boundaries. So, what are the advantages of one over the other? Which method is more preferable?

We are making road , it has intersections with simple roads wich leads to forest or a fields or to a private territory. We have 60 of those intersections (crossroads) , if we would start making them all with intersection wizzard it would take a lot of time... , maybe there is simpler way to make such an easy crossings ? ( all of those crossroads are same type same geometry, the only difference is location)

I went forward designing intersection profiles with limited survey and simply made an educated guess for the secondary roads pgl tie in point. I have received updated survey and when I move the profile end point to meet existing grade it adds another pvi effectively holding the profile grade I set preliminarily. I'm keeping the lock point. Is there something with the return/ offset profiles preventing this edit? What is the proper work flow?

Using the Best Practices, different components in their own DWG files, all brought together in a production sheet where I can place the labeling for that sheet. I can add labels for Surfaces, Alignments, Pipe networks, through the Xref(s). Evidently this was not extended to Intersection Objects.
What I'm doing now is creating a new Intersection at each street intersection just so I can get a label which shows the station of each alignment at the intersection. Is there a better way to do this?

I am working on a water line replacement job in a residential neighborhood. Some of the streets are getting the water line replaced and some are not. I have created an alignment for the water line on the streets that are being replaced.
When I create my view frame group along each alignment, there are some overlapping view frames from different alignments. I need to create a matchline for these instances. How to create matchlines for view frames on different alignments? Or create one view frame group from different alignments?

I have a proposed road with a varying curb line. There is a minimum 5 foot tree lawn between the back of curb and sidewalk. I have used a lane transition and attached it to an alignment to get the curb to follow. Also used the urban sidewalk with buffer widths.
How do I connect the back of curb to the sidewalk and keep the sidewalk in the same offset from the baseline. In the attachment, I have used a zero inside boulevard width and slide the sidewalk over from the curb line in my assembly. Will this work?

what is the benefit of using corridors rather than simply using all of the things that go into a corridor--alignments, surfaces, profiles, sections, assemblies (which I don't understand yet either)--independently?
Is it just for design visualization? Does it have any benefit for developing construction plans?

I'm designing a single 2% cross flow blke path. I wanted to reverse the cross flow so I created two corridors, one flowing to the left and one flowing to the right along the same tangent centerline. I want to add a 50 foot warp transition in between them. I'n not sure how to do that. I thought of the intersection design but that won't work.

Changing the curb return radius after the intersection has been created. I am able to go back to the curb return parameters dialog and enter a different value, but once I hit Enter or OK the value reverts back to the one I orginally used.
So it looks like I have to delete the intersection object and re-start the wizard from scratch. Not that it's a big deal, just thought there might be a way to make the change once the intersection is built.

I would like to find out if it is possible to produce a drawing with more than one view frame plotted on a single sheet/layout. I was thinking of minimizing on the number of sheets used for Linear features.

I have a decent understanding of how corridors work, and I am able to generate material volume tables for earthworks, I can edit my corridor and everything is all synced up as far as I can tell. Where I am having trouble is removing topsoil (with a volume generated) and then using that new 'section' to calculate cut and fill.
The project is a new road for a subdivision. Topsoil is to be stripped only within the limits of the back of curb, and anywhere the fill is greater than 300mm (a foot).
What I was trying was to use the stripping topsoil subassembly, with a foreslope of 0:1 and a width based on my corridor. I would have this subassembly on the let and right, and the attachment point would be the crown of the road. Then I would create a surface using the stripping feature lines and the stripping link to calculate the topsoil removed. Then I would use this surface as the Base to compare for my Earthworks.
The problem I was having is the Topsoil surface wouldn't follow the actual topsoil feature line in the sections, and would get some pretty wonky stuff happening with regards to the TIN lines of this surface. Flipping the TIN lines seems very difficult to do properly and efficiently.

I was happy to get my Data Shortcuts set up (1) for myself: to create corridors of different design scenarios in separate drawings, and (2) to share data with my project team members.
Referencing and viewing them seems to be ok.
But I haven't been able to model a Corridor along an alignment, profile, tying to surface referenced from data shortcuts. I think I did once, then had problems after removing and re-creating, maybe re-naming some Data Shortcuts. Is that a "No, no" ? I didn't mess with any of the XML files, created everything from Civil 3D. I might have to delete everything and start with a fresh Data Shortcuts folder.
When I re-select Alignment and Profile for Corridor, then OK - it locks up. I created new sample lines along the new alignment. Maybe need to start with fresh corridor. How much am I going to have to re-create? Possible hang up locations?

Trying to add slope markings on my corridors, and the only way I can find is to do it in the Corridor properties > Slope markings, then click add slope pattern, which asks you to select featurelines top and bottom of slope. Surely there is a way to simply switch on or off slope markings where in cut or fill?

How do you merge a ramp on to the main highway using corridors? Also how would you make that surface with two different alignments? I have my main road alignment and a ramp that comes on to it so the problem I'm having is making my 3d model with the road and surface combine.
