Anyone tried it out yet?
http://labs.autodesk.com/utilities/civil3d_terrain/
C3D2012-x64 only at this time.
am not sure but i clicked save workspace icon after loading TS cui.
please explain the procedure
Yes I did that it didint work.
thanks trogersnow it works.
Hi Justin,
Thanks for giving it a try. We would like to learn about your workflows and incorporate them into the product. We would like to get the details of the crash you encountered so that we can fix it. Please send your feedback to the email distribution list: labs.civil3d.terrain@autodesk.com.
Thanks,
Smita
I've used the pond tool a bit now. I like what it does so far. I think the video said not to do it... but I have grip edited my pond feature line to change the shape and it seems to update fine and in fact in grid view it's FAR faster than normal Civil 3D.
A couple of suggestions I would have are (some of these might stem from my lack of knowledge of the features):
Thanks for your feedback. Most of the points you mentioned are only limitations of the labs preview and will be addressed in a feature release. Let me explain each point one by one:
1. We are not trying to sound a death knell of Tin at all. We view this as a complementary approach to modeling and editing. In future, you will be able to extract Tin from a grading grid to get the finished ground.
2. We have not done any work on performance, hence the solids are slow. The model being demonstated in the pond video was fairly large (at least 50,000 triangles within site boundary). We hope to address this limitation in future.
3. The grid view is meant only for conceptual design stage, so the volumes are rough. Solid representations are very accurate and so are the solid volumes. (Currently, we are not displaying solid volumes but we would do so in future.)
4. In future, we would improve the interface with a graph that contains operation nodes (primitive elements and combination rules) to reveal the hidden steps behind model creation. Currently, the best way to understand the hidden steps would be through the User Guide. For example, refer to page 5 of the User Guide to see "Behind the Scene Operations" for pond creation.
Please feel free to send any further questions/feedback to the email distribution list: labs.civil3d.terrain@autodesk.com.
Thanks,
Smita
Thanks for the response - I'm hoping to use the terrain modeller over the next few weeks on my own dataset....

Thanks for your suggestions. Let me make sure I have understood them fully:
1. Do you want the rim width to transition along the boundary according to some rule? I don't think we can do this now even with the working elements because currently, we are not supporting transitioned offsets, but this is just a limitation of the labs preview. I imagine that you want to specify offsets at some points along the boundary and have the width transition in the intermediate regions, right?
2. Cut and fill grids are unbounded and always extend up to the site boundary extents by design. (Contrast this to bounded cut and fill grids that extend up to the distance you specify.) However, when such grids are combined with the finished ground, the portion beyond the existing ground is trimmed away. Let me explain this with an example. Let's say you want to grade from a feature line in fill. This involves two steps:
Alternatively, you can use Add Fill (in Add Fill panel) to perform the two steps using one command. When you sub-select the fill grid (using Ctrl+Select), you will be able to see this grid in its full extents. To summarize, the finished ground will always contain cut and fill grids that have been trimmed so that they don't extend beyond where they intersect with the finished ground. The advantage of this approach is that it offers a flexible design and many working elements can be combined with each other to create versatile shapes before using custom fill/cut commands to combine them with the finished ground.
3. Interesting point. I have taken a note of this. I imagine this to be an option on the History dialog where some operations can be turned off (similar to tin operations) so that they don't appear in the finished ground.
4. This is again a limitation of the labs preview. Hide finished should be used only when you have working elements. If you accidentally hide the finished grid without creating working elements, then undoing is the only way now to turn it back on.
Thanks again for your valuable feedback and we look forward to more suggestions from you. Please keep us posted.

Smita,
1. Yes, that's it exactly. Often we will need to have a wider rim on the outlet side of the pond than on the inlet.
2. I've seen the behavior I mentioned on terrain shapes, which are finished ground I think? Here is a screenshot showing a pond shape which has the cut projected like I mentioned before.
Thanks for attaching the image. I understand the problem now. The cut grid (in red) is emerging in two other places. This is a side-effect of unbounded gradings. We have included some tools to fix this. I will show you two ways of getting around this problem:
1. Holes: Draw a closed 2D poly line (I prefer a rectangle) around the problematic region. Run Create Hole located in Modify Element panel. Choose the cut grid and the poly line. A hole will be created in the grid and so the region inside the hole won't show up in the final surface. You will have to create two holes to get rid of both regions.
2. Bounds: Draw a closed 2D poly line around the pond to indicate a rough boundary of the pond. Run Bound Element located in Modify Element panel and choose the cut grid and the poly line. The cut grid will now be clipped by this boundary and any piece of cut grid that was appearing above the ground outside this boundary will disappear.
Question for you: Would you like to specify an approximate boundary of the pond when you run the pond command? This will ensure that the cut and fill grids do not project beyond this boundary. You can change the boundary later. Let us know.
Thanks,
Smita
I've started digging into it and have been blogging as I go.
Nice article – you’ve gone further into the functionality than many other bloggers!
A suggestion regarding the warning message about associated objects - this one should not be ignored. It may cause problems with object updates if you modify something. You are getting this message because there is a circular dependency:
1. The flat bounded plane derives its extents from the feature line. (Bounded plane operation)
2. The feature line derives its elevations from the flat bounded plane. (Fill Grid with infill operation)
To avoid this, you should create an unbounded flat plane in the first step. That way, when you create a fill grid with plane as infill, it will use the plane to define the interior only and the results will be the same, except that you would not have created a circular dependency.
We will be posting some more videos on the labs site to demonstrate commands on the right end of the ribbon tab. So stay tuned.
Smita
Smita, thank you for clearing this up. I tried what you said and it worked beautifully. I even added a new blog post about it.
