Extract Objects from Surface in Civil 3D 2008

Have you ever wanted to grab out just ONE contour from your surface for a cut/fill line?  Or maybe you’d like to turn your pond contours into polylines for some volume calcs?  In Civil 3D 2008, you can grab things like contours, triangles, borders and more while keeping your surface intact.

I used this tool today for a rendering project.  I grapped the border from my road surface and used the resulting polyline as a hide boundary in a copy of my Existing Ground.  Very cool.

    Way cool. Sure beats blowing up a copy of the surface just to get two polylines. I’m probably stating the obvious, but the objects you extract become static, right? I expect as much, but how cool if they knew when their ‘parent’ updated?
