Design Contours

[SAIMA JALIL]

Hi

I need to show the design contours up to shoulder and tadpole for the batter extent. How can I trim the design tin only up to shoulder extent .??Generally tin models include sections and strings for the super alignment.



Thanks

hi

simplest way is to use "Utilities > A-G > Change, filter select the strings for the road and copy to a new model, triangulate that.

or
you could create a closed polygon using the edge of shoulder strings and "Null by Polygon"

or
using "Utilities > A-G > Delete, filter and delete strings by name. the ones outside the shoulder.

or
use Model > String Info Table. select the road string model, sort the list by name and delete strings using the delete string button. once you select a string, you can keep pressing the delete button until all the string codes you don't want are gone. see pic attached.

there are likely several other methods, these are the ones i thought of.

I presented a webinar in 2016 that demonstrated a general technique for this:
