Terrain Model

Hello, 

1) Do you have "True" select for the node property "Update ground elevation from terrain model?"

2) If "yes" to #1, does it help if you move the node location very slightly? (which should trigger it to update the ground elevation)

3) What product and version are you using? (check under File > Help > About, or Help > About for older versions)

4) What type of terrain model are you using? (Bentley DTM? LandXML? Etc.)

Yes, when I slightly moved node it changed the elevation after Design and analysis run.I am using LandXML. But the ground profile showing abruptly changed at rim as in the previous figure.

To update the ground elevation do I need to draw the inlets and pipes over scaled background layers otherwise how it will update the ground elevations at the particular place.I used schematic network. 

Hello Hari,

What workflow are you following for this?

After importing the terrain if you are laying out the network on it, the ground elevations should automatically update if the "Update ground elevation from terrain mode'" is set to "True".

For the elevations abruptly setting at the rim, we would need the model files (.STSW, .SQLITE) along with the terrain (LandXML) for testing

Can you share your model along with the terrain for testing?

After importing from inroad I add few networks in stormCAD, now my ground elevations are little bit different due to some cut and fills, so I would like to update ground elevations for those inverts after cut fills, which I previously drew in existing ground.

And I also add two Landxml file one in stormCAD one with existing ground and other with proposed ground.Can  I able to see both ground elevations for the same point in my profile.

To update elevations of existing elements, you can use Trex (Terrain Extractor). 

The Terrain Model feature can be used when adding new elements to a model. In our upcoming CONNECT Edition Update 2 release (due at the end of this month or early November), we plan to introduce a feature where you can choose to re-apply a terrain model to existing elements, to update the ground elevations. 

You are using an old version, and I recommend upgrading to the CONNECT Edition. The problems you're experiencing may have been fixed, plus you would be able to access other new features such as Catchment Delineation. If your organization has a SELECT subscription, the upgrade can be done at no additional cost.

You can only have one active terrain model at a time. You could reopen the profile after changing your active Terrain model.
