ditch profile & alignment assembly question

i've got a ditch that has to be a minimum distance from the travel lane. it also has to have foreslope of 4:1 max. the ditch can move away from the travel lane at 4:1 but it can't get closer than minimum distance. i've got a ditch profile that varies quite a bit causing my ditch to be closer to the travel lane than the minimum required. what type of subassembly would you use to a) make the ditch follow the ditch profile and b) lessen the foreslope when the ditch gets shallow enough to cause it to get to close to the travel lane? is this a case for a conditional subassembly? thanks.

If you switch from the Roadway mode to the Layout mode in Subassembly Composer's Preview pane then you should see what it will look like when inserted into a subassembly in Civil 3D. This setting ignores all targets for calculation purposes since there are no targets associated with an assembly prior to being part of a corridor. You will need to change some of your default values that the targets override in order to get a link to display (you will want to change a 0 somewhere).

sweet! that got it. thank you very much.

i listened to the 2 presentations about the subassembly composer and i followed what was going on but to learn it i think i need something a little more basic. any recommendations?
