Grading Corridor Loop

[jmoore.218473]

Does anyone know if there is a way to get the grades to stop after they reach their target without using a boundry.

The picture below is part of a loop track, and as you can see the grades are not stopping where they're supposed to (at target surface), and continue to other parts of the corridor.

I have no problem using boundries, but it seems to me that they should stop once they reach there target.

Thanks,
Jon

Sorry Forgot the image.

I didn't see an image.

I know what you're talking about. That would be a nice feature to just stop at the end of any assembly targeted or not.

Did you try to exclude triangels above a certain length? Perhaps this will do what you want.

[jmoore.218473]

That might work. How do you enter a maximum length?

[gandocadguy]

In your surface properties box on the DEFINITION tab under the BUILD section there is a maximum triangle length. You set that to something less than the offending triangles but longer than those you want to keep. It may not get rid of all of them but it should get you pretty close.

[jmoore.218473]

It helped a little, but it was still triangulating for distances that were a lot longer then what I had entered for a maximum. Maybe I'm missing something? I ended up just deleting the triangle lines were going past the maximum entered.

(I entered in 80, but it was still going a distance somewhere around 1400')

Thanks,
Jon

That's the way TIN surfaces work. When you create a corridor surface, you are just creating a regular ol' surface with corridor data added to it. There are three types of data you can add to a surface from a corridor, links, feature lines, and boundaries.

I personally would be very upset if a corridor surface just stopped at the limits of the corridor automatically because most of the time I don't want it to do that (don't do much highway design).

If you are using 2010, you can right click on the surface under the boundaries portion of the corridor properties and choose to "add the corridor extents as boundary" (or something like that). That will pretty much do exactly what you want it to.
