Creating a vertex/line where vector data touches the surface

I was wondering if there was a way to determine where a vector feature meets the terrain surface in the main viewscreen, and if it does, to place a vertex or a line at those points. Currently the only way I can think of is to put the vector data (lines and polygons) into 3D mode and to guess at a correct position.
If not, is it possible to have the program determine this and place a vertex at the appropriate place(s) on the line, or create a line feature showing the places where the polygon intersects the surface?
Thanks so much, and if this is actually in the wrong forum, please move this thread to the correct place!

What you can do is select the linear feature with the Digitizer Tool, then right-click and select the Analyze submenu option to show a path profile for the line. You should see both the 3D line path and the terrain surface so you can easily see where the line passes into the terrain. You can right-click on the path profile and select to create points at a cursor location to drop points there. I will also add a todo list item to automatically do this.
Thanks,
