Trying to use the "Create Terrain Model from Design Meshes" tool.
Works great. But it creates a terrain from all the components in and referenced in the dgn. There seems to be no way to turn off a component from being included in the terrain. Level displays (view display, global display and global freeze) don't work , clipping a reference or turning off a reference don't work. I just want to exclude one or two components. For example a wall or barrier component with a vertical face. Or a temporary component I made for targeting or quanitites.
Please advise. The tools seems like a easy way to create a terrain, just need some type of controls so it doesn't select every component mesh referenced into the dgn.
Corridor
Terrain created with this tool. North corridor is referenced to dgn, but the display is off.
Shawn,
I see what you are getting at and that would work. I was looking for something dynamic. I know drainage folks use terrains for design and I would like to keep them updated without spending a few hours or so getting an updated terrain. I am using multiple models in multiple files, with surface templates, linear templates and corridors created by multiple people. A lot of times breaklines (geometry) may be draped on top of other features and so sorting out linear features is possible but time consuming. I have used the graphical filters, but this tool has the same problems as the described tool above, in the fact you can't turn off levels, fence clip or selection set elements you want to include in the new terrain.

Glad I found this thread. I've been trying to create a design terrain model for a complicated design consisting of a number of roundabouts using both linear and surface templates at regular intervals along the main corridor. The command appears to run through the process but then hangs. Says it is still processing but nothing happens. Zane's comment "Alternate surfaces don't work with surface templates" may be the reason why. Wasted too much time already trying to get this to work. I'm going back to the graphical filter method.
cheers,
Mick
