Roadway section grading in Autocad
Roadway section grading in Autocad
(OP)
I am trying to get a roadway section to follow an alignment in for grading calcs. I am working in Autocad 2006, with the land desktop package. I have defined an alignment (both vertical and horizontal), and saved my typical section. I can not seem to get the section to follow the alignment properly (the contours always show something slightly different). I also can't find anywhere to set how the outsides of my proposed section are to be graded to meet the existing grades; I'm looking for a 3:1 slope to meet existing. Any pieces of advice or online sources of information? I've picked a few things up from the help section in autocad, but it mostly seems worthless.

But first you will need to define a template for your road then use design control to generate cross sections
when you get to wierd areas like intersections and road width changes you can use 3d poly by elevation and transition the breaklines in the grids.
Hope this helps

When I first did templates, I always drew it in a drawing that only contained the template, and I set the H & V scales to 1.
If you draw the template in your design drawing, use the template drawing routine in LDD. You don't want to just draw polylines and define it, use the routine.
Do a Google search for Land Development Desktop and the name Phillip Zimmerman. Zimmerman has written several good books.
