Roadside Ditch Corridor

237 Views, 3 Replies

I am trying to create a road w/ ditch corridor that takes the ditch elevation from a created profile and calculates the offset from the shoulder based upon a 4:1 slope. I've tried a number of different sub-assemblies and can't seem to get it to calculate the offset correctly. Any help would be greatly appreciated. Thanks.

Try LinkSlopetoElevation. It can have a target profile for the elevation. The slope is shortened or lengthened to the target at the slope specified.

I am currently using the LinkSlopeToElevation subassembly, with a -25% slope and it isn't calculated the offset correctly... for example on a elevation difference of 1.42 it is calculated the offset to be 11.61 instead of 5.67. I can't seem to figure out why it isn't working for me.

Well I decided to just go ahead and delete my assembly/corridor and start over... it is now working using the same subassemblies as before. Thanks for the help.
