All,
I followed the steps in this video (http://www.youtube.com/watch?v=8UON7jngtRU) to create a terrain model from a corridor. However, the terrain model that was generated does not follow the surface of the corridor (see screenshot below - the light blue line is the terrain). Does anyone have any ideas about where I may have went wrong?
Also, more generally speaking, if anyone has any best practices or recommendations on the best way to create an overall surface terrain from a model several corridors, civil cells, and other elements, please share! So far, I've been creating several smaller terrains for each object and merging them together into a complex terrain. That seems to work okay, but it can get pretty complex and convoluted. Is there a better way?
Thanks for your help!
Matt
Hi Matt,
My only thoughts are you may have ticked the exclude from triangulation button for the road crown and LHS lip of kerb string in the template creator. I wouldn't think it was a feature issue as the RHS kerb lip has been included.
With regards to terrain models I use the design stages to filter what feature types I want to include in the terrain model. I would then reference all the individual DGN files into one master file where I can capture in a single terrain model.
Hope that helps!

Your corridor seems to model "breaklines" with different z-values and same xy form top view, that's not possible for terrain models based on delaunay algorithm.

Matt,
There was a mistake in the video that was posted and I have removed it from website. I will be recording a new one as soon as possible. Instead of importing the corridor as a terrain model element, you need to import the corridor mesh. I will post the link for the updated video as soon as it is available.
Thanks Jaquelyn, that clears things up. I'm looking forward to seeing the new video. If you could provide some tips in the video regarding combining surfaces (e.g. a composite surface from a roadway median civil cell on top of a corridor or a corridor adjacent to a to an entrance civil cell) that would be a huge help as well.
Dan,
I appreciate the advice. I need to become more familiar with design stages and how to take advantage of them.
